408 with rear mount 76 GTS dyno
Hi guys, i just had a 76 GTS turbo put on my camaro. It's a 408 with a 4l60 tranny, with a VIG 3200 TC. I still have my 373 gears, i know i should have lower. But with the big MT on back, it helps alot. It was really hot and humid out today, the DA was around 3000. We was only able to go to about 11.5 lbs of boost. Ran out of injector, but the GTS has a lot more in it. Had a E-boost 2 boost controller installed also, seems like a very nice unit. She ended up doing 686 HP and 675 lbs TQ, this was on a Mustang dyno. With the 4" exhaust...WOW!...she sounds really good. We did a quarter mile run on the dyno @ 8 lbs of boost, I didnt have enough gear for 11.5 lbs of boost. With a terrible 60' on the dyno,(1.82) and the 1/8 (6.89) @ 111.2 and the 1/4 (10.48) @ 136.6

Hey bcs, if you go to EPP's website and look under project cars, look for Scott's camaro, you will see most of the information. There the motor is a 382, with the 408, only parts that are different is the block and pistons. No meth, just a fmic, and my IAT's, at the end of the pulls only went up maybe 10 degree's, if i remember right. I know it wasnt much higher than at the start of the pulls. Maybe that means th 76 isn't working very hard. And my 60 lb injectors are not up to the job. My heads are TEA stage 2 LS1's.

Cool those EPP guys are on it. I bet she is loud, after I removed the pipe for the air filter and place the air filter on the turbo with a 3 inch dump you can hear the spool twice as loud I love it. But what is the differance between a GTS76 and what you have?????

I don't remember what brand my 60's are. And yes, it's the bad boy fuel system Bob and the boys @ EPP done for me. Unfortunately I didn't go bigger with my injectors.
