Default Fairly Stock 4.8L and S475 on 12psi
Finally got my truck on the dyno with my turbo set up. Should be fun when I add 10 more psi to it. Shooting for 800rwhp

Engine:
Stock untouched bottom end 4.8L
Stock untouched 4.8L 862 heads
LS9 head gaskets
ARP head studs
Stock48 Triple 12 cam
LS2 timing chain
TBSS intake
LS2/7 throttle body

Turbo Kit:
Cast S475 with race cover
Trick cast T4 log
4" down pipe
4" core intercooler


578rwhp & 547rwtq. Not sure why but the graph looks like it shifted left 400-500rpm. I pulled it to 6500 or so and it showed peak hp around 6200 on his computer.

Wow those are some damn good numbers. I would have guessed lower. A little head work and you would break 600 super easy. Any track times?

HASHTAG VTEC 4 LYFE

Gamble, oh I have track times. They are horrible. 12.3 @ 113 is my best I need a transbrake to get off the line. I've never been below a two second 60'
