Turbo 5.3L w/ 4L80E and STOCK STALL
my turbo 5.3 trying to push through the
long 4l80e 1st gear using a stock converter.
3000 RPM stall installed. Problem at 5,500rpm, but you see the improvement.
Idling and test drive
5.3 Twin Turbo Camaro Project
This is a project I'm currently working on. It is a series of pictures of
the things I have taken apart and modified on a 91 Camaro. I have made some of the
items shown in the video. With all the mods I'm doing to the engine the car
should end up being around 800hp! Once it's done I will upload another
video of it taking off. In the mean time check out

Trans AM FM MPT70 5.3L LM7 528hp 491tq (1BAD LS1)
This is my current setup, Front mount Master Power T70/.96AR turbo, Pullout 5.3L LM7 8.5:1 compression, 317
heads, 02 ZO6 Cam, COMP 7.425 pushrods, I Custom Fabbed the Merge pipe and
down pipe, FMIC, 9" 370 gears, VIG 3600, Tuned by me (1BAD_LS1 TUNING
It made 528HP and 491TQ with 22* timing, 14psi, 11.5afr at only 5600RPM
(trans was slipping like a mofo) it will make 600hp + easy! Those are the
best numbers the car put down because the trans/converter kept getting
worse and worse....
Those numbers were also made with a high stall auto Vig 3600 with a cracked
hub, a stock slipping 460e, and a 9" with 3.70's !!!!!!!!! I need a better
tranny/stall/gears because what i am running in not turbo friendly at all!
UPDATE... installed a th400 trans, new rear gears, and a few more psi!!!!
no Dyno numbers but i
would bet the car would put down close to 700HP!
