Kenne bell 2.6 3 1/2 pulley

[Cre8tivinstinkt]

New to the site and I stumbled upon this thread. I have a 04 mustang gt that I just had forged rebuilt .20 over, cams, ported heads, 72lb injectors, return fuel system, and added a 2.6 Kenne Bell mammoth w a 3.75 pulley. Have it at the Dyno and the tuner guy says the car only makes 8psi and 427 rwhp..does this sounds correct?

Any one out there with a 2.6 and a 3 and a half pulley, what mumbers did you make? (Pump gas) Very curious previous owner of mine thought it was a 2.8 with a different size pulley then whats on there. So i dont know if i trust his hp numbers haha. Thanks in advance!

If it is only making 8 psi of boost, then yes, that is in the ball park. Stock cobras with an Eaton don't make 420 on 8 psi of boost. Cobras with 15-16 psi make mid 400's.

Turn it up to 16-18 psi if the motor is built to handle it. Cobras are in the low 600 hp range on 16-18 psi.

Not sure how 2V's are related to 4V's.
