JohnC Posted May 4, 2022 Share Posted May 4, 2022 Going to try and show the mods start to finish…. Here was my 2010 Camaro SS 6.2L L99 with 6L80 as is when I bought it. Quote Link to comment Share on other sites More sharing options...

JohnC Posted May 4, 2022 Author Share Posted May 4, 2022 Before I found sport mode, it ran 8.8’s in Drive with TC on. Mods already on car when I bought it were Varam hot air intake and Corsa catback. Quote Link to comment Share on other sites More sharing options...
JohnC Posted May 4, 2022 Author Share Posted May 4, 2022 From there, cat deletes, Cold Air Inductions CAI, widebands, and HP Tuners along with a trip to Beech Bend got me in the 8.5’s in the 1/8 and 13.1 in the 1/4 once I found Sport Mode.

JohnC Posted May 4, 2022 Author Share Posted May 4, 2022 Next was Circle D 3400 stall, full 3in Kooks exhaust with Kooks LT’s, TFS GenX 255’s, TSP VVT 3.2 cam and DoD delete from TSP, etc. First start: This got me in the 11.7's with TC on and with all season radials.

JohnC Posted May 4, 2022 Author Share Posted May 4, 2022 After this, I tried to get a new 6th Gen ZL1, but couldn't cut a deal I was comfy with. That said, I decided to supercharge the 5th Gen instead. I did the DSX auxiliary pump, ID1300X injectors, and already had the ZL1 pump in the tank. We welded in the AEM wideband bungs in the new Kooks connection pipes and hooked up the AEM widebands. First start after ProCharger D1X install: Quote Link to comment Share on other sites More sharing options...
JohnC Posted May 4, 2022 Author Share Posted May 4, 2022 Took it to DBR for a tune and switched to the 3.9" pulley. Made about 13lbs boost peak at 6,800 rpm's and 760rwhp. Quote Link to comment Share on other sites More sharing options...

JohnC Posted May 5, 2022 Author Share Posted May 5, 2022 Right after leaving the dyno, I gave it a WOT test run on 840 and ended up blowing the rear main seal out. So off to the shop again to replace that. I also fixed the issue by installing a Mighty Mouse Camaro 5 Wild -12an vented catch can. Quote Link to comment Share on other sites More sharing options...
JohnC Posted May 5, 2022 Author Share Posted May 5, 2022 After this, the 6L80 started slipping. So I decided to do a built Stage 2 Tim Kng Racing CTSV 6L90 swap with external trans cooler, Circle D Pro Series triple disc 3400 stall and one piece driveshaft. We had to make a custom mount as the CTSV 6L90 is longer than the 6L80. Old 6L80 coming out…^ Quote Link to comment Share on other sites More sharing options...
JohnC Posted May 5, 2022 Author Share Posted May 5, 2022 About 2 days after the fresh 6L90 went in, the pump failed and broke the bell housing as well, so back to TKR for another refresh and converter. After that maybe a year later, the TC solenoid locked the converter, so a WOT downshift broke 4th, 5th and 6th gears. This time, I sent it back for a Stage 4 Max Effort rebuild, new TEHCM, new valve body and Zip Kit. Also got the car retuned. New parts for fresh build and of course fresh full synthetic fluid and filter was done... 2nd build back from TKR Quote Link to comment Share on other sites More sharing options...
JohnC Posted May 5, 2022 Author Share Posted May 5, 2022 So now the car started over heating and having cylinder imbalance OBD2 codes. It was down on power and not running good at all. I thought I was lifting a head gasket, so I bought ARP head studs, LS9 head gaskets, etc. Turns out it was just a stuck thermostat on the over heating issues, but we found valve train issues in the tear down. Broken rocker arms and worn push rods... We replaced the TSP rockers with stock rocker arms and Smith Bros trunions along with BTR push rods.

JohnC Posted May 5, 2022 Author Share Posted May 5, 2022 After all the bugs got worked out, I put on some DR’s and re-dyno’d the car. It put down 781rwhp with 400 less rpm on TKR’s dyno! Before valvetrain was fixed, 760rwhp at 6,800 rpm's. After valvetrain was fixed, 781rwhp at 6,400 rpm's. Quote Link to comment Share on other sites More sharing options...

Ashley P Posted May 26, 2022 Share Posted May 26, 2022 I hope you get some good passes on it soon. I'm studying the trans mount, but I can't tell if it's "solid" or not....? The reason I ask....I think it's highly unlikely for the pump to break and cause the bellhousing to break. It's likely the other way around. Double/tripple check driveshaft length and make sure the trans mount is more flexible than the engine mounts. Quote Link to comment Share on other sites More sharing options...
jamtoy Posted June 13, 2022 Share Posted June 13, 2022 Other than stroking mine to 427", I think we will have very similar builds. Same heads, cams are close and I went with a fast intake and NW throttle body. Once its back and I get some miles on it then its fuel and supercharger. Not sure which procharger to go with though? My goal was always to stay pump gas but that probably will change. 1 Quote Link to comment Share on other sites More sharing options...

I have a 3.9" pulley and its making 781rwhp at 6,400 rpm's through a 3400 stall and 6L90 slush box. Quote Link to comment Share on other sites More sharing options...

JohnC Posted June 16, 2022 Author Share Posted June 16, 2022 Fwiw... A TSP forged 427 in a C6 ZO6 on just under 11 psi via D1X N/A 604/527 Pump Gas + Meth 895/721 wheel E55+Meth 948/756 wheel This Vette used to run the D1X Quote Link to comment Share on other sites More sharing options...

jamtoy Posted June 16, 2022 Share Posted June 16, 2022 (edited) Yep forged and dropped compression about a point. Darton sleeved at 427ci. should hopefully get on the engine dyno next week and if all is well car should be done soon after. would like to see near 500rwhp na. That’s on a stingy mustang dyno.
