1986 third gen Trans Am turbocharged 5.3 LM7 LSx runs
Couple WOT runs in my 1986 trans. Setup is a 2005 5.3 stock bottom end, 317 heads, LS6 cam and valvesprings, LS6 intake manifold, and custom fabbed turbo setup with a turbonetics 76mm ball bearing turebo. Currently running 5 PSI but engine will take 12-14 PSI. Car has a T56 tranny with a textralia clutch as well.
Turbo TPI Iroc - Modded ZZ3 350 13 psi - First day at drag strip runs 7.71 at 92.2 mph on radials
Best run of the day and it was on a 1.84 60 foot, so easily could have ran a 7.5x on sticky tires. I was just about the only person on regular radials today. Soon I need to get a bigger turbo and it should open the doors to some low 7's. All in all I'm pretty pleased although I had expected my mph to be closer to 94-95. Engine is a ZZ3 crate motor modded to forged internals. See my other vids for more specs
