Dynoed 4 exceptional cars Saturday, big cubes, 2 stage N20, wheel and weight comparison, and our stage 1 ported manifold compared to our stage 2 ported manifold.
Was a pretty hot day 90F+

Ported FAST, alky injection, Full exh.
The dyno shows the peak TQ @ 5100 RPM the car makes 15PS1 @ 5100 as well but falls off to 11psi. This car should be on par for 680RWHP- 720RWHP depending how high we can turn it.
Lino stg 1 to stg2 intake
This is the highest stock exhaust manifold car I have seen. We did a comparison of a stg1 manifold porting vs our stg 2 porting. This Car is an 07 Z06 with the following mods:
Callaway CAI, Fasterproms Ported TB and stg 1 manifold, STOCK EXH manifolds, B&B Fusion catback, Fasterproms
Run 1 was a baseline pull with all aforementioned mods, fully optimized.
Run 6 was Stg 2 manifold and a tuning tweak, more fuel.
