07 GT manual.
4.75l Stroker, Forged internals, balanced ,9:1, Ported stage 3 heads, with stage 3 blower cams.
Stock intake manifold, Stock TB, Paxton 2200sl, 3:33 pulley with CX racing intercooler HPx MAF, Tial BOV.
60lb injectors, S&H 477 Drop in, 12ga direct wire, big line kit at intake. Lots of fuel at WOT 12.4 AFR. 6400 rpm redline.
Tuned on 91 ( no ethanol)
436whp on a mustang dyno, max BO0ST 8LBS, At 4200ft
I am wondering if there is an intercooler restriction ( 12"x24"x3") or should I pulley down? Max RPM currently on Paxton is 46k rpm. Paxton says good for 52K.
I was hoping for somewhere around 12psi, and 550whp. Which I don't think is excessive as the engine is more than capable of more boost. If you add the correction factor for the Mustang Dyno( I'm guessing) on 12% that's somewhere around 485whp on a Dyno jet.
Any input is allways appreciated.
thanks
