  1. Things are progressing, although never as fast as I'd want it to. The room is a struggle to work with since one side has large glass windows and the other side is open with a bar, stairs, and a hallway. There are large bedrooms on each end of the media room so the room can't be expanded those directions. They did a modal review of the room and initially placed the subwoofers in these locations. THe subwoofer where the arrow from from was not going to work in that position as it would have to stick out in the floor. My suggestion In the bar area where I drew the red box is an ice maker that no longer works and is too expensive to fix. It made 60 lbs of ice a day so it's not a little icemaker. ๐Ÿ™‚ WE have plans on removing that and adding shelves, but it would be a great place for that subwoofer to go and it would be hidden. We can add black fabric panels in place of the wood panels that you currently see. The original modal graph looked like this. Notice all of the peaks. After their original placement it looked like this. Much smoother. Again, the room is far from ideal. We will be using acoustic panels extensively in order to help with the room acoustics, and the rest will be managed during the final Trinnov calibration.
  2. Got my car back from Balanced Performance Motors today after having a few changes made to it this week. I had to replace the low pressure fuel pump (LPFP) that I had purchased from Tapout Tuning since it couldn't hold enough pressure on E85. It was supposed to be a "Stage 2" pump, meaning it wouldn't have any issues running straight E85, but testing during the tuning process showed that the pressure was dropping to 45 lbs or so which is not anywhere close to what it needs to be. It will be sent back for a refund. This is a picture of the pump/housing that came out. It is a DW400 pump but apparently the venturi in the housing is the restriction to the flow and the reason for the low pressure. I installed an XDI Stage 1 LPFP and it is supposed to be sufficient to run E85 up to the limit of the stock turbos. Specs: OEM ATSV ACDELCO LPFP Specโ€™s: 377 LPH without back pressure. 215 LPH at 70 PSI XDI Stage 1 Spec's: 435 LPH at no back pressure 265 LPH at 70 PSI 23% Increase overall Maximum Pressure >80 psi at full flow (PLV opening pressure 85-90 psi, stock is 70-75 psi) See chart. Fuel Compatibility: all known fuels, all Ethanol blends Fitment: 100% OEM, no cutting, no crimping Tuning Support: HPT, Trifecta While the car was there, I had them replace the plugs with NGK Ruthenium plugs since I knew it still had the stock plugs. The plugs were gapped at 0.026" which is what is recommended for these cars running the boost levels we are seeing. I also installed a new Renick cold air intake (CAI), here's a picture of the installation. Click to enlarge. The new system consist of two equal length tubes each with its own filter. "Equal length ensure that the compressor wheel on each side of the LF4 has identical RPM response as they spool up and spool down. The LF4 has matched mirror turbos for efficiency why not have a flow matched intake as well? This helps make the engine respond identical on both banks with maximum efficiency. " The CAI kit also came with an oil catch tank to prevent any oil from reaching the turbos. So... I need to take the car out and get a pull or two and send it off to Justin to refine the tune a little. The plan now is to get the car on the dyno the last week in July to see what it's making, but it should be somewhere between 620-640 whp. Can't wait. Assuming nothing breaks, I'm done with changes for this car for a while. Famous last words... ๐Ÿ™‚
  3. Done with appearance items for a while! Thanks to James Renick for many of the items on both the cars. We couldn't be more pleased with how they turned out. There is always more to do though... the fun never stops. ๐Ÿ™‚ The wife's car now gets: Cue update so she can get Android Auto New RE-alignment. Yes, to fix the current one AEM wideband/XDI translator/plugs install Justin Schmidt tune to replace the Trifecta tune I'll have them service the diff/trans/anything else that needs service when it's in for the Cue update... it has 56k miles My car needs: Have to replace the Tapout Stage 2 LPFP that is supposedly a DW400... we'll see but I don't think it is. I have a new XDI LPFP pump waiting to go in. Install Renick CAI and new plugs To the dyno to see how well Justin has done ๐Ÿ™‚ After the dyno I see I need more power, we'll install a fuel cam. Not much left to do now! Here is a link to more of the pictures that I took today: ATS-V Appearance Items Done - Google Photos PHOTOS.APP.GOO.GL 25 new photos added to shared album
  4. Finally. It's taken a long time but all of the appearance items are done and the wife LOVES it. ๐Ÿ™‚ So... we had the hood, fenders, and front bumper cover re-painted, the front splitter was refinished, both front grills replaced with the ones you see here, all the emblems were replaced, roof and mirrors wrapped black, and ceramic treatment. The springs and wheels and tire don't hurt. ๐Ÿ™‚ Now all we have to do is install the wideband sensor and XDI translator (for the high pressure fuel pump), and then I let Justin Schmidt loose on the car to tune it. I will get it re-aligned as soon as the shop I go to gets its new alignment machine. I also need to get it back to a dealer to get Android Auto on the Cue system. Midway through 2016 Cadillac added it, but this car was made early 2016, so they have to do an update to make it show up. This first picture was taken today (06/13/21) at Amicalola Falls State Park.
  5. It has a HPFP and LPFP and is now running on E72
  6. The Big Canoe Car Club had a little gathering that we went to yesterday, and I managed to capture a few pictures. Big Canoe Car Club - 05/01/21 - Google Photos PHOTOS.APP.GOO.GL 61 new photos added to shared album
  7. Washed both cars today so that we can take them to the Big Canoe Car Club meet tomorrow. It's getting there... just a few more items. The guy that did the painting did a great job matching everything up. He painted the bumper cover, hood, and both fenders, and also fixed the pits etc in the front splitter. The new grills are installed and the "V" emblems have been ordered are getting replaced along with the ATS in the rear (black). The car will get a ceramic treatment and the roof and mirrors with get wrapped black, and hopefully it will be done the week after next. Since there isn't much to do as far as power goes, I'm saving that for the end. I just need the XDI translator, wideband sensor, and some new plugs installed, and it's ready for a Justin tune. Both parts are sitting in the garage, so hopefully in the next few weeks I can get Teddy Knisely to install those on the car and we'll be off to the races. ๐Ÿ™‚ The wife loves her car... ๐Ÿ˜‰ BTW, this is Obsession Red Tint Coat.
  8. Got the wife's car back from the painter today (Russ Cowart) and he did an awesome job! He painted the two front fenders, hood, front bumper, installed the two front grills, and refinished the front splitter. Now we have to get it ceramic coated, clear wrap the front of the car and rear bumper cover, wrap the roof and mirrors black, and finish changing out the emblems. All the chrome is gone except for the ATS letters and the three V emblems and those will be changed soon. Then it's off to get the wideband sensor and XDI translator installed and get it re-aligned. Love the black grills, and I think that's the way they should have come to start with.
  9. We took the wife's car to Russ Cowart for the front end painting. I stopped by on Friday to get some pictures of the car and take a look at what he's done so far. By looking at these pictures, you'd think the car had been in a wreck. ๐Ÿ™‚ For reference, here's before. And this is now. It's a three stage paint process, so it's more difficult to get right than a single color paint, and the big reason I took it to Russ. After the paint is completed, we're going to take some additional steps to protect the finish this time. The car will get a complete GTechniq Crystal Serum Ultra ceramic treatment including the wheels and calipers (the same treatment I have on my car). The front bumper cover, hood, and fenders will get a clear bra wrap along with the rear bumper cover (to protect behind the rear wheels), the glass will get a protective film, and the roof and mirror covers will be wrapped in gloss black. Her car is really going to look like new. I made this comment on a ATS-V Facebook group. The two grills in the front are being replaced with gloss black grills with a new emblem like the one that he added to the rear of the car. After adding this one to the back, we decided the the silver "ATS" and the "V" emblem looked out of place now. So I've ordered these. There are three of the V's on the car, one on the right rear, and one on each side of the front doors. So, while I was ordering, I've ordered new black grills and emblems for my car as well. They are the only pieces on my car that aren't black so I'm going to fix that. I also received my new rear trailing arms for my car, and hopefully I can get those on next week. These bars (six total) help to accurately locate the rear axles/wheels under hard acceleration and cornering. The red car already has these installed. Here's a comparison of the stock arms and the new ones. With 600+ whp the stock arms and bushings will flex which can cause unpredictable motions in the rear suspension. When I accelerate hard in my car I can feel the rear end moving around, partly because the tires are loosing traction and the electronic diff is compensating by locking and unlocking the two wheels, but also because the rear is squirming because these bars and bushings are flexing. It will be interesting to see what difference these bars make on the track or autocross course. I'm scheduled to run a BMW/Porsche autocross on May 16th, so I'll find out how well they work pretty soon. Speaking of my car, we're on the 13th tune file at the moment, and Justin has bumped up the boost so we can make sure the fuel pumps can keep up. I need to get a log file to see where we stand, and hopefully I can do that tomorrow. I talked to Jason Plante at Balanced Performance Motors about getting on the dyno next week and told him I'd call Monday to see what we could work out. He's also the person that will be installing the rear trailing arms (about a two hour job), so maybe I can get both done next week, we'll see. I'm really anxious to see what kind of power it's making now. Most of the cars that have similar modifications are making 600-630 whp, but I'm going to find out for sure. The limitation will be how well the high pressure fuel pump can keep up. Justin will be tweaking the tune while we're on the dyno so that we can get everything out of it that we can. If I want to get more power out of engine in the future, there really isn't much left to do. A fuel cam and cold air induction is pretty much it except for new turbo's which I won't do on this car. The fuel cam is really just an exhaust camshaft with a lobe on the rear that drives the high pressure fuel pump. To get more fuel, there are fuel cams of varying lobe designs that can increase the pump output by 20%-45%. With the addition of the fuel cam and cold air intake, we can get the car to about 650 whp, and I'd be real good with that. ๐Ÿ™‚ The wife's car is the big horsepower car and that's fine with me. I can still drive it. ๐Ÿ™‚
  10. It is in the shop right now, I'll be making a new post shortly.
  11. Yes, this is the one with Turbobay turbo's.
  12. The wife was taking the car out yesterday and I wanted to get the exhaust sound. But it's still a phone so it is what it is. It actually sounds pretty good through the music system that's attached to my TV. You may hear a little "clink" sound as she starts up the hill. We think there is something in between the wheel and tire that is moving around. The guy that is doing the paint work is going to look at it. As she backs out, you can see that the hood is a little scared up and the front end pitted. He's also going to try to sand the splitter and try to make it look close to new. The exhaust uses the stock rear muffler system, but in front of that it has New Era Performance downpipes with a Vibrant 4โ€ resonator and custom 4โ€ single mid pipe. This is the car with Turbobay turbo's. Wish I had a couple of those snails on my car. ๐Ÿ™‚ Maybe she'll let me drive. ๐Ÿ˜‰
  13. We got the wife's car back two days ago with the new wheels/tires/springs on it. I drove the car today for the first time and it rode great. The alignment is not what I would have specified, so I'll get it back to the alignment shop in a few weeks. We drop off the car again on Friday to Russ Cowart at HOME | cowartcustoms WWW.COWARTCUSTOMS.COM to have the front painted and to installed the front grills. They will buff out the rest of the car, and at some point will probably get a ceramic treatment on it. Before we do that we'll have the roof wrapped in gloss black as well as the mirrors. At that point everything is done except to install the XDI translator and wideband sensor and then I'll have Justin start working his tuning magic. I took some pictures comparing he Swift springs (left) to my Eibach springs. You can see that the Eibach's are a little lower. The rear wheels stick out a little further on the sedan, so it's a good thing that those springs aren't as low. When they were trying to adjust the rear suspension, they discovered that one of the camber bolt washers were just spinning on the bolt. These were on the car when we bought it and these were not OEM parts, so not sure why they were changed out with incorrect parts. 20210407_120926.mp4 My car is on it's 6th E85 tune file and the car is currently running on E68, and it appears to be running like gangbusters. The gas pumps only have E71 right now, but I'm hoping that as the warm weather takes hold they'll start bumping that up closer to E85. I took the last log file (for Tune #5 - E85) and looked at the 55-95 mph time from a pull I made two days ago. Since I don't have Dragy yet, I used the times and speeds from the log to see how quick it's running now, so none of this is scientific, I'm just getting a ballpark. These times are on PS4S 305's (brand new ones at that), so no really sticky tires to help out. For the 55-95 mph pull, and the best I can figure, this is what it did: 55-75 mph - 2.223 seconds 75-95 mph - 1.992 seconds It looks like the tires are spinning in the 55-75 mph range, but once they hook up it pulls strong. This is Dragy. Dragy Motorsports DRAGYMOTORSPORTS.COM Monitor your 0-60mph, 60-130mph, 100-200kmh, 1/4 mile, 1/2 mile performance, and more!

  14. We were suppose to pick up the wife's car today but it won't be ready until tomorrow, so I got out and washed the car instead. ๐Ÿ™‚ Yes, it was a little cold but the sun was shining and I had 120 degree water to work with, so not a problem. I finally got to put my foot in the gas briefly since it was dry outside today, but I wasn't logging the car at the time, but MAN... this thing is making some serious power now. ๐Ÿ™‚ I'll get out tomorrow and log it and see how it's doing. I have about 3/4 of a tank of E62 that I'd like to run down as low as possible so I can add about 13-14 gallons of E85 (or whatever percentage is coming out of the pump) In the meantime, I thought I'd get some pictures of the fitment of the new tires in the front. This is the way that Cadillac should have done it from the factory. Before the front had a larger gap between the fender and tire, the new tire size fixes that. Everything is tucked in and nothing rubs. I do have -2.5ยบ negative camber in the front and -2.2ยบ in the rear, so that pulls the top of the tire in a little more than other people might have. Here's a zoomed in view of the front.
  15. Picked my car up at noon in the pouring down rain today. The new Michelin's are now on the car. Since I couldn't get the Falken tires that I wanted, I got the tried and true tire. But this time I went from a 265/30-19 to a 275/30-19 in the front and so far I haven't noticed any rubbing except in a tight parking maneuver which I can live with. There is no more room in the front or rear, so this will have to do except for a stickier tire. While the car was there, the new stainless brake lines were installed as well as new Porterfield R4-S front and rear pads. Since everything was apart the system was flushed with Motul 600 brake fluid. Jason told me the fluid was really brown, so obviously cooked. Not good at all. After I picked up the car from the shop, I went to fill it up with some more E85. I had been running E43 and still had some left in the car, so when I filled up with 11 gallons of E85 (the car holds 16 gallons) I ended up with a tank of E62. Since it was pouring down rain on the drive home, I couldn't try it out, nor did I have my datalogger anyway. But I will take it out tomorrow and make a few pulls in it to see how the fuel system holds up. We'll be looking to see if the high and low pressure fuel pumps can keep up. There's no doubt the low pressure pump (DW400) will be able to provide enough pressure, and I'm pretty sure the high pressure pump will be able to do the same, but the high side will be the weakest link in terms of making power. The only way to overcome that would be to add a fuel cam to the engine. A fuel cam is a an exhaust camshaft that has a lobe on the end that drives the high pressure fuel pump. By changing the size of the lobe, you can increase the amount of fuel the pump can supply. Tapout sells a 21% fuel cam, ZZP has a 45% cam, Weapon-X has a 30%, etc. My high pressure pump is a 35% pump meaning it supplies 35% more fuel than a stock pump. If you add a fuel cam, just add the percentages together to get an idea of the fuel increase. To max out the turbos, I will need a fuel cam at some point, but right now I didn't want to crack the engine, so the pumps are the answer for now. If they can provide enough fuel with straight E85, even at reduced power output, it means I don't have to worry about running any variation of ethanol, the tune will be correct for any blend of ethanol and 93 octane. ๐Ÿ˜‰ I discovered there is a dyno at Atlanta Motorsports Park, so I'm going to look into taking the car there to tweak the final tune and see what kind of power it will make. I drove the wife's car down to pick mine up, so I left hers at the shop to have the Swift springs installed as well as mounting the tires that came off my car on her new wheels. We will pick that one up tomorrow afternoon. Can't wait to see what that one looks like! At that point I'll have a set of wheels for a coupe and a set of wheels and PS4S tires for a sedan for sell.
  16. Dropped of the car at Balanced Performance Motors today. Tomorrow I'll pick it up with new Michelin PS4S tires, new brake pads, new brake lines, and a brake flush. I'll do my best to run it out of gas before I bring it back home as I need to fill it up with E85 so I can finish the tune with Justin. When I pick my car up, we drop off the wife's car so they can install my tires on her new wheels and install the new Swift springs and hopefully we can have hers back on Thursday. I'm on my 11th tune file with Justin. We're going to throw as much E as we can to see how much power it will make. The thought is that it will run full E85, but whether it makes full power at that level is another question and one we hope to answer. I shared this earlier today.
  17. Well... another setback. I can't get the Falken RT660 tires until June since there is a nationwide backorder. So in the meantime, I've ordered another set of Michelin Pilot Sport 4S tires and they will arrive Friday. Of course that means I don't get any work done to the cars this week, so we're now looking at next week before we can get all of the wheel/tire/suspension/brake work done to both cars. I did go ahead and order a 275/30-19 for the front, and that new size will be going on my car to replace the 265's that are on there now (those go on the new wheels for the wife's car). Sooo... we'll just have to wait another week. I have been working on the remote tune for my car with Justin Schmidt. We're on the 5th iteration of the 93 octane tune at the moment, and I hope to get that version in the car this morning so I can go out and make a few pulls to log the data. The rain returns tonight, so I'd like to get as much tuning done today as possible since the car won't be going out again until the rain is over. Power wise, the car appears to be much stronger with this new tune than with the Trifecta tune and now we're just working out some part throttle smoothness at this point, so I'm pretty excited. I can't wait to dive into the E85 tune to see what it will really do. I need to schedule some dyno time but I have to wait until all the other work is done first. The biggest pain in doing all of this is scheduling things, especially when you have delays with parts/tires/etc. But we're coming down to the wire as there isn't a whole lot left to do to either car. For mine, it's finishing the 93 tune so we can start of the flex fuel version, getting the brake work done, installing the rear trailing arms once they become available, and finally getting some grippy tires to help harness all of this power. For the wife's car, I need to get the tires and wheels on the car, install the springs, install the XDI translator for the high pressure fuel pump, take the car to have the front end painted, have the new grills installed, and wrap the roof and mirrors. At that point, we need to spend some time on the dyno and let Justin tune that one and we'll be done for a while. Yea... right. ๐Ÿ˜‰
  18. I took my car to Atlanta Motorsports Park last Sunday for my first day at the track with the car, and my first time at that track. It was a blast! The car did very well, I really could not have been more pleased. You can tell that the engineers spent a lot of time sorting out the cars track capabilities, as there was nothing that it did wrong and nothing unpredictable about the way it drove. I was impressed. The 300 treadwear Michelin PS4S's actually did really well, they had a lot of grip and showed no real handling quirks whatsoever, and the alignment seemed to be spot on. The only issue I had was the fact that I didn't have a chance to flush the brake fluid before I went, and after about 3 sessions on the track I pulled back in to let the car cool down some, and when I got back in to drive again I had no brake pedal at all. Apparently, the fluid boiled while I was sitting still, because I never had any fade or any other brake issues while I was on the track. Once everything cooled down, the pedal came back and I could drive it home. I'm just glad it showed up while sitting still instead of at 100+ mph and trying to slow down to 30+ mph in Turn 1. That would not have been good. So, I have new brake pads (Porterfield RS4 front and rear), new steel braided brake lines for the front and rear, and we'll be flushing the brake fluid with something that is track friendly. All of that will be happening next week. I'm waiting on the 2 new rear tires (Tire Rack says they should arrive today) and the steel braided brake lines (Friday) to get here so we can take both cars to Balanced Performance Motors to get all of the work done. It seems like the longer I have to wait, the more things I find to do. ๐Ÿ™‚ So this is the current list for next week. Both cars will go at the same time and they will be there for a day or two, but hopefully just one. Dismount my tires (Michelin PS4S) and mount/balance on the new wheels - wife's car. Install the Swift springs - wife's car Mount/balance new tires (Falken RT660) - my car Flush brake fluid - my car Install new brake lines - my car Install new pads - my car We'll drive her car around for a day or two to let the springs settle, and we'll take it back for an alignment. All of the new hardware that was installed last week on my car worked perfectly at the track. The high pressure fuel pump, low pressure fuel pump, flex fuel sensor, and wideband gauge all worked great and are good to go for the E85 tune. I tried to remove the Trifecta tune from the car yesterday but had issues, so I'm going to try that again today. The Trifecta tune has to come off the car first so that I can send the stock file to the new tuner. Once he gets that, he'll send me his 93 octane tune back to me, and I flash it to the car. I'll then go out and log a few 2-4 gear pulls, and then send him the log file back. He'll then tweak the tune based on the data from the log file, and send it back to me to flash to the car. We may go through that several times to get it right. Ideally I would do tha ton the dyno, but I'll save that for the E85 tune. Once we have the 93 octane tune down, work starts on the E85 part of the tune, and that will happen on the dyno. According to Justin, I should be looking at about a 100 rwhp increase with his E85 tune versus the 93 tune, so "maybe" going from 520 whp (Justin's 93 tune and dp's) to 600-620 whp. I would be VERY happy with that power. That is basically a 700 hp at the crank engine. I thought I'd share a couple of pictures I took at the track. There were a lot of very nice cars out there that day and I wasn't sure how my car or myself would do compared to everyone else. Once I got comfortable and started passing people, I had the answer. ๐Ÿ™‚ I need a lot more work though, I was really rusty after three years of not going fast, so I definitely will be back again and again. ๐Ÿ™‚ Plus, the next time the brakes will be better than they were, the tires will be grippier, and the engine will have another 100 horsepower. ๐Ÿ™‚ And I'll turn on the data display next time. ๐Ÿ™‚ You can see the kart track in the center of the road course. It is huge. The have enduro races and open lapping, so there's another thing I'll be doing this year. ๐Ÿ™‚ I told my wife I just need to buy one of their new trackside condos and live there. ๐Ÿ™‚ This video taken when three of us were on a leisurely pace behind the instructor so we could get familiar with the track. This is the only time I had the data overlay turned on unfortunately, so that's why I included the video here. It gives you an idea of the data I will have next time.... you know, when I won't make that mistake again? ๐Ÿ˜’ I had planned on using my GoPro too, but never did that either. I'm a real slacker... ๐Ÿ™‚ This video was made using a dashcam that we use on vacations and trips, and at least it shows the speed even though it lags what the car was doing. It's also 1080p in stead of 720p like the camera in the car (above).
  19. I took my car to Teddy Knisely last Friday for have the low pressure fuel pump, high pressure fuel pump, flex fuel sensor, and AER wideband sensor installed. The LPFP is installed and working as well as the wideband sensor, and he is installing the flex fuel sensor and HPFP tonight, so hopefully I'll have it back tomorrow. I'm still waiting my tune file from Trifecta that I requested last week, so can't put any E85 in the tank until I get that. This is the new low pressure pump and old pump. The gauge for the wideband sensor is going behind the little door where the cigarette lighter is, so it's completely hidden if there is no reason to be looking at it. That is not mine but it shows how it goes in the area. Two of my new tires have already arrived at Balance Performance Motors, and the last two (along with new TPM sensors) should show up tomorrow (Wednesday). After that, we'll get both cars there to do the wheel/tire swap/installation as well as installing the Swift springs on the wife's car. I have her wheels sitting in the garage (image below). We're swapping my Michelin PS4S tires on her wheels and the new Falken tires go on my wheels. I don't know how much, if any of the wheel/tire stuff will be done before the weekend. I should have my car back tomorrow (Wednesday) and hopefully have the tune file by Friday. But I doubt the new tires will be on the car by then. I was hoping it would all be done, because I get to go to Atlanta Motorsports Park on Sunday for a AMP Bring-A-Buddy Day event. We have a gentleman here in Big Cane that is a member there, and he secured 10 buddy passes for a whole day at the track. In order to drive at AMP, you have to have a SA rated helmet. The helmet that I've had since about 2012 was about to expire and it wasn't fire rated anyway, so, I went to Discoveryparts.com at AMP today and bought a new helmet. It fits great and doesn't have a bunch of sweat in it. ๐Ÿ™‚ So I'm ready to go! It ought to be a blast! First time at the track and the first time in my car!
  20. 02/22/21 My car has been at the dealer another 10 days. Cadillac was called on Friday. I finally got to talk to the technician and explained what was going on, so he now knows what do to. What a waste of a month. The good news is the the wheels for the wife's car have shipped! Now I need to call Gran Turismo East and get scheduled to install. The images below are the wheels on my car, and hers are EXACTLY the same in every aspect except for the rear offset which is slightly different between the coupe and sedan.
  21. I relate to Tim Allen in more ways than one. ๐Ÿ™‚ But I certainly agree that everything could use more power. ๐Ÿ™‚ I'm doing things to our cars right now that give them more power, and it takes lots of power to drive a media room, so this will be my new "engine" that I'll be using for my power. I've always owned high power amplifiers from early on. The speakers that I've owned have been inherently inefficient do to their design and required a lot of power to drive them, and their low impedance made that even more difficult, so having a stable high power amp was very important. I also like having "headroom" or a reserve of amplifier power. There is nothing worse you can do to a speaker than to drive an amplifier into clipping. Speakers are generally forgiving of amps that can drive clean power into them for musically brief time periods, but when an amp starts to clip the music, the severe distortion that it generates can destroy a speaker in a heartbeat. I'm going to be using two amplifiers, one for the front three channels, and one for the other 6-8 channels. The main amp is going to be the ATI flagship model AT-6003 designed by Morris Kessler. I'll do a little copy and paste so you can read more about the amps. This image shows a 7 channel AT-6007, mine will be a three channel AT-6003, otherwise no different. The 6000 series amplifiers, available with 2 to 7 channels, are the companyโ€™s flagship power amplifiers for over a decade. Furthermore, their โ€œsignature seriesโ€ designation with a facsimile of Kesslerโ€™s signature on the main panel acknowledges the special nature of these designs. Beyond Kesslerโ€™s personal identification, these amplifiers are new in more significant ways. As in Kesslerโ€™s previous top-of-the-line designs, these amplifiers are fully balanced, differential amps, but unlike his earlier balanced designs which were essentially balanced bridged amplifiers, the 6000 series uses only a single input stage with dual-differential output stages. The reason: the advantages of balanced designs are retained and noise is reduced by 50%. The design uses current feedback instead of the more common voltage feedback. The reason: current feedback amplifiers are faster with virtually unlimited slew rate and are better able to reproduce todayโ€™s best music and film sound. Kessler used Thermaltrak output devices for the 6000 series. Unlike traditional designs where external diodes or transistors attached to the heat sinks track the amplifiers operating conditions and use the details to adjust bias, Thermaltrak devices have the temperature sensing device in the same package as the output transistor. The results: bias is optimized in real-time. The 6000 series use dual DC servos to track and maintain DC offset. The result: DC in the amplifierโ€™s output is reduced to insignificant levels. These amplifiers use a revised PCB layout. They are still modular with the complete amplifier including the power supply parts on a single card, but now the AC components are on one edge of the board and away from the signal input. The result: improved signal-to-noise performance. All of the amplifiers in the series use dual toroidal transformers, dual power switches and dual line cords. The results: the AT6002 is now a complete dual-mono design and the amplifiers with many channels, as in the 7-channel AT6007, can be hooked-up to two independent 20 amp circuits for greater sustained output power than is possible from a single AC circuit. All the amplifiers in the 6000 series are rated at 300 Watts RMS from 20 Hz to 20 kHz with no more that 0.03% THD at 8 ohms with all channels driven and 450 Watts RMS at 4 ohms under the same conditions. Signal-to-noise ratio is typically 128 dB referenced to full output so each amplifier in the series is capable of playing back the full dynamic range available on todayโ€™s lossless recordings. AC Power Connector - The AC input connector provides power to the unit with the supplied power cords. The 120VAC version of the 6000 series amplifiers is supplied with two 15 Amp power cords with standard NEMA-5-15P plugs on one end. The 230VAC versions are supplied with Schuko IEC 60320 with C19 plug. Some 230VAC versions are supplied with a different plug. Here are some reviews of the amp: Link to review Link to review Link to review Link to video The rea and surround amplifier will be an ATI 5000 series amps. The exact amp will depend on the final number of channels it will need to drive as they have models from 2 to 8 channels of power. ------------------------------- The AT500NC Series amplifiers use Hypex N-Core Class D output modules with ATI designed input buffers and linear power supplies and are available with two power configurations. The AT52XNC amps are rated at 200W RMS per channel at 8 ohms with 300W RMS at 4 ohms and are available with 2 to 8 channels. The AT54XNC amplifiers use two N-Core modules per channel in a differential bridged output configuration delivering 500W RMS per channel at 8 ohms and 900W RMS at 4 ohms. The AT54XNC amplifiers are available with 2, 3 or 4 channels. These AT5XXNC series amplifiers break new ground in other ways. They are the first ATI amplifiers to use micro-processor control for turn-on delay and feature automatic AC power recognition and configuration. The amplifiers not only recognize whether they are hooked up to 117V or 230V nominal power, they automatically self-configure. The amplifiers also incorporate a new and novel โ€œsleepโ€ circuit. When the amplifier receives no input signal for a period of 10 minutes, power is removed from the output modules and a front-panel LED begins to flash. As soon as an input signal is detected on any channel, normal playback operation resumes instantaneously. Per Morris Kessler, ATIโ€™s president and chief engineer, โ€œWe are excited to offer amplifiers with ATIโ€™s legendary high performance and reliability in designs that reduce amplifier weight by up to 50%.โ€ With rated distortion below 0.05% and signal-to-noise ratio of 123 dB (minimum, referenced to rated output), each amplifier in the series is capable of playing back the full dynamic range available on todayโ€™s lossless recordings.

  23. Every home theater system has a sound processor of some type to manage the inputs and outputs as well as the sound processing. On low end systems you would have a receiver that would handle those chores, and as you move up you might have a dedicated preamp that handles the same task. as you know, there are many different types of sound formats in use and they all require decoding in order to send the sound to the correct speaker. Some receivers/preamps even have their own automated calibration setup that utilizes a calibrated mic to adjust the time delay, frequency response, etc of your speakers. My Onkyo receiver has such a thing built into it and it came with a calibrated mic. But the fun doesn't stop there, and there is a whole other level of processing power that can be had, and this is the one piece of equipment where I will spare no money. This time around I'm going to be using a Trinnov Altitude 16 processor. This is the ultimate home theater/media room processor you can get right now (other than the 32 channel version which does all the same things, just with more channels). And know that this processor is not a bunch of hardware, it is a sophisticated computer with hardware attached to it and everything is done in the software. The tuning capabilities of this device are phenomenal and I can't even begin to describe what it is capable of in my own words, so lots of copying pasting here. ๐Ÿ™‚ There is a link to the manual toward the end of the post in case you are interested. During the installation process, a gentleman named Adam Pelz will be handling the calibration of the system. Adam is the best in the country with the Trinnov calibrations and is also very familiar with the Wisdom Audio speakers that I want to use, so I couldn't be more excited to know that I get to use his services. Combine all three for an audio match made in heaven. ๐Ÿ™‚ I'll have lots of videos along the way but I'll certainly have some videos of Adam doing the calibration. ----------------------- NO COMPROMISE The groundbreaking Altitude32 processor set the bar high -- and we didnโ€™t lower it for the Altitude16. Delivering the same processing capabilities and sound quality as the Altitude32 processor, the Altitude16 makes Trinnovโ€™s best-in-class performance accessible to a wider audience whose immersive audio system requirements will not exceed 16 channels. Equipped with Dolby Atmos, Auro-3D, and DTS:X Pro immersive audio decoders, the Altitude16 renders up to 16 discrete channels of information, natively processes high-resolution 24 bit / 96K audio, enables up to four-way active crossovers and presents no limitations in terms of Atmos and DTS:X channel assignments or subwoofer outputs. TRINNOV OPTIMIZER Our world-renowned Loudspeaker/Room Optimizer is recognized as best-in-class by users and reviewers across the professional, commercial cinema and high-end home audio worlds. Introduced to the pro audio market in 2006, its revolutionary solution was quickly embraced by many of the most demanding music, broadcast and post-production sound engineers. Optimizer technology is now used in nearly 2,000 studios across the globe with nearly 10,000 high-performance installations worldwide. This same technology, enhanced and refined over the years, is at the heart of the Altitude. To this day, the Optimizer remains the most powerful and flexible calibration system available. UNIQUE DECODING AND RENDERING Dolby Atmos The Altitude16 joins the Altitude32 as the only AV Processors on the market capable of decoding and rendering Dolby Atmos Home content with any 16-channel speaker layout. When it comes to channel count, the devil is in the details when it matters which channels are supported. Within its 16-channel capability, the Altitude16 supports any speaker layout, including multiple side surround speakers and high numbers of subwoofers. DTS:X Pro In 2019, Trinnov worked closely with DTS to introduce DTS:X Pro to the consumer market. Altitude owners enjoyed this major upgrade a year before our competitors could offer it. It benefits not only native DTS:X playback, but also the Neural:X upmixer, which greatly improves immersive playback of traditional soundtracks, maximizing speaker usage and listening envelopment. Auro-3D The founders of Trinnov and Auro Technologies know each other well, having been at the forefront of immersive sound research and development dating back to the early 2000's. Auro-3D, up to 13.1 channel configuration has been available on the Altitude32 since 2015. The Auro-Matic upmixer, highly popular among Altitude owners for music playback is also supported for all inputs. UNIQUE BASS MANAGEMENT The Bass Management solution in the Altitude gives users the most sophisticated tool available for managing low frequencies. Complete flexibility regarding high and low pass frequencies, filter types, and filter slopes is just the beginning. The low-frequency content of any channel can be fed to any combination of subwoofers, and there is no limitation to the number of subwoofer channels other than the number of available outputs. Going further, our unique intermediate bass management system is ideal for immersive systems using smaller height channel speakers. It can redirect low frequencies not just to subwoofers, but from a speaker with limited bass capability to the closest, more-capable speaker, before sending the lowest frequencies to the subs. EXCLUSIVE 3D REMAPPING TECHNOLOGY In real-world rooms, we canโ€™t always place speakers where we should. And in any case, Dolby, DTS, and Auro each have a different idea of where they should go. Trinnovโ€™s exclusive, patented Remapping is the only solution. During calibration, Trinnovโ€™s unique 3D microphone precisely maps the location of each loudspeaker in the room regarding distance, azimuth, and elevation. When decoding a particular soundtrack, we know the intended placement of each of the various sound elements. Then Remapping, taking the reality of the room into account, โ€˜remapsโ€™ errant sounds to the proper locations by using adjacent speakers and the principle of stereo imaging. ---------------------- I can talk all day about this, but take a look at these case studies from people heavily involved in the music and home theater world as well as awards. Awards Case Studies Technical Paper Webinars Manual Loudspeaker Placement Guide I can't even begin to talk about everything this processor can do but there is plenty of information on the Trinnov website if you are interested. Here's a short video of the object oriented viewer showing the visualization of the sound going to the different speakers in this Trinnov trailer video. Just amazing stuff. I'll obviously have more about this product when the time comes.
  24. Ahhhh.... the nitty gritty. Yes, we have to make the room look nice AND sound nice, but to get the "sound nice" part, you need to start off with some hardware. It's like a car. It's one thing to make it look nice, but to make it fast, you have to throw hardware at it. ๐Ÿ™‚ Just like the weather, there are a lot of pieces that go together to make a good system, and along with the hardware, one of the most important pieces is the room itself. That is a whole other post as it gets complicated, so I'll save that for later. I'm sure that some of you know, there is unlimited money that can be thrown into home theater rooms. Millions of dollars is not uncommon. Take a look at these speakers, there are considered to be the most expensive (and maybe the best sounding) speakers in the world. So home theater is really it's no different than anything else. You can spend a ton of money on a car that goes really fast and looks really good, or you can spend less and get something that may not run quite as good, but you are either willing or forced to take the trade off. Usually it's forced thing. ๐Ÿ™‚ The plan until the designers change it is a 5.2.4 system but I have no idea what the system designers will come up with. I can't do 7.2.4 as I can't use side speakers due to the configuration of the room. In case anyone is wondering what those numbers mean, the "5" is for the three front channel speakers and two rear channel speakers, the "2" is for two subwoofers, and the "4" is for four ceiling speakers. The processor I will be using can mange 16 channels of sound, and I'll talk about that in a totally separate topic, but I could add an additional 5 channels of sound if I had a location, and right now the ceiling might be the only location. This Trinnov Altitude 16 processor is the key to making this sound awesome and nothing like what you can imagine. ๐Ÿ™‚ Every time I start to think about what equipment I want to use in my room, it changes. Not everything mind you, and really it's just one piece, and arguably the most important piece of all the hardware... the speakers. No matter what other equipment you use, as good or bad as it may be, the speakers are responsible for reproducing the sound coming from the amplifier as accurately as possible without adding any of their own sound or coloration to the music. Speakers have gotten much better over the years and it's not hard to find good sounding speakers in most any budget category. But when you start stepping up in price you begin to enter another realm in sound that starts to make you go "wow". Ask anyone that has listened to music where the music has brought an emotional response to them. As a matter of fact, go to YouTube and look up "Hallelujah Pentatonix Reaction" and tell me how many are brought to tears. That is what quality music can do to your soul, and I have felt it myself with my current system (but not hear at this house). Version 2.0 is coming, and I'm going to do my best to bring tears to your eyes if you come to listen. ๐Ÿ™‚ You should and will feel in awe, and not because of massive volume, but because of the realism, presence, and dynamics. I've felt it, heard it, and want it in my room. You no longer are just listening to music, it surrounds you and places you there with the performers. I really think it's something you have to hear to understand, and when you do it's a earth moving moment. I think one thing that makes choosing speakers so difficult is that there is no way you could ever possibly listen to every speaker system to compare. Sure, for low end speakers you go in a showroom and they have 20 pairs of speakers setup and they can flip back and forth no problem. That's not the case with higher end speakers. In many cases, you might not ever hear the speaker you are going to buy because the closest place is 500 miles away. Some companies like Ohm Acoustics don't have resellers anymore, they sell direct. At least they give you 120 days to try the product, but most manufactures don't. So you have to rely on reviews, electronics shows, and word of mouth from those that have been in the business for 40 years. I don't really have much of a problem with that, although it would be nice to hear the speakers before buying. I will caution that when you go to listen to speakers, just know the room is changing the way they sound, so when you get them in your home your results may be different. I cannot emphasize enough how important the room is to the sound and why the room will be a separate topic. I've loved my Ohm Walsh 5000 speakers, and I have seriously considered using the newest Ohm speaker, the F5015, for my two front L/R speakers. I don't think that for the money, you'll find a better speaker. To replace mine with the Ohm F5015 it would cost about $5500 each which is a GREAT price for what you get in my opinion, but this time around, I don't think I want floor standing speakers. I've started with a budget but that seems to be a moving target as the design process starts. The person doing the design, Shawn Byrne, suggested I don't lock anything in until the design gets going. He will work with the room calibrator to make sure the speakers I want will be a good fit for the room and room volume. What I want might be overkill and if so, I want to know that since it would help to save money. Without getting into all the different speaker types, I'll talk about a type that I want to use in my room. You can break speakers into two different categories, although there are some that don't fit neatly into either one, point source and line source and it describes how the sounds radiates from the speaker. I'll do some copying and pasting so you don't have to go look it up... ๐Ÿ™‚ I want to use a line source speaker. One other thing about these speakers is they use a special type of driver called Planar Magnetic drivers. Front Channel Speakers You might have noticed a reference to a speaker called a Sage Series L75 in that quoted section... and that may be one of my target speakers along with the Wisdom Sage Cinema Line 2, but it will really come down to what the designers of the room determine to be the best speaker for the room. Keep in mind I'm only talking about the L/R speakers at the moment. Wisdom Audio is the company that makes the L75 and Sage 2 as well as other line source and point source speakers. The L75 series can be free standing, surface mounted, or in-wall mounted. This is the floor standing L75 with and without a cover. The two top sections are the planar magnetic drivers. This is the flush mount hidden version of the Sage 2. The hidden versions are framed into the walls which is likely the route I will take, but again, I have lean on the designers of the system. Rear Channel Speakers The rear channel will also by line source speakers from Wisdom, most likely these L8i models. These share the same pair of 24" planar magnetic drivers as the front L75's and Sage 2 speakers. These would be mounted in the wall. Center Channel Speaker This will also be a Wisdom speaker but just haven't identified which one yet. Ceiling Speakers I had these picked out, but I'll wait on these as well. I'm sure a lot of this will change and I might have to throw it all out of the window. As mentioned earlier, due to the design of the room I will not be able to use side channel speakers so nothing to pick for these. If I had 4 walls I'd use the Wisdom's for those as well. I think that's enough for now. I'm tired. ๐Ÿ™‚
  25. I finally have a plan... ๐Ÿ™‚ My car has been at the Cadillac dealer for three weeks now as they tried to figure out what the clunking noise is in the left front of the car, and it appears that the front sway bar migrated to the left and was touching something and making that noise. I've ordered collars to go on the bar that should arrive Tuesday that will keep it centered with the frame, hopefully that will fix the problem. Next, I have Friday March 5 appointment with Teddy Knisely to install the flex fuel sensor, Aric Miller high pressure fuel pump, AEM wideband sensor, and Deatschwerks DW400 low pressure fuel pump (Stage 2 Tapout) on my car, and he'll also be installing the Swift springs and AEM wideband on the wife's car around that timeframe. James Renick said the new wheels for the wife's car are done, so they should ship out the week of February 15th, so I will need to call Gran Turismo East to get some tires and schedule the alignment after the springs go on. After that we'll get the car to the people that will wrap it, get the grills/emblems on it, and make it pretty again. ๐Ÿ™‚ ZZP told me the rear trailing arms for my car wouldn't be available for another 4-6 weeks, so once those come in I'll get Teddy to install those as well. New tunes are all I will need after the items list above are completed. I'm so ready to be done with installs... I want to play now.:-) The end is in sight.
