Nice gains! 23psi huh? Can you run that high of boost on 93 octane or does it require race gas? What was the power on 15psi? Very impressive for so few mods.

23psi is race gas only. 17-19 psi is max on pump for kb's (usually)

It needs and octane booster to make over 730 RWHP, it made 656 RWHP on 16 psi which is the 91 octane pulley they send with the kit you can run up to 720 RWHP on just 93 octane.

Awesome numbers! I bet with a set of long tubes and full 3" exhaust it would break 700rwhp on pump gas.

Thats the thing with FI cars, They will make insane power and still be docile on the street. Especially those 4v mustangs.

great numbers. what are the specs of the stock engine? compression ratio? cams specs? is the rotating assembly forged steel, forged aluminum pistons?

thanks.

those cars need blowers to make torque at all. modular mustangs without a kenne bell or whipple are junk. stock gt500s run 12.4 thats slow with a blower and 500 horse. but congrats thats insane power.
