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.

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'
