I calibrated a Powerdyne blown 302 for a guy with an XW ute.
It had Edelbrock heads,ED Sprint/Cobra intake, the wrong camshaft,65mm t-body and the blower made a piddly 7lb....the powerdyne bracketry deflected so much it's no wonder it couldn't make 9lb!.
It achieved a best of 432hp @ 5600rpm and over 400lb/ft for more than 1500 rpm of the rev range.
Engine management was EECIV(of course) recaled with an EEC-Tuner, 30lb injectors and 70mm Ford Racing MAF. We tried an 80mm MAF but it actually made less power...likely due to the backflow inhibitor being in place still.
This was tuned on an Superflow 901 engine dyno that was operated in a very poor way. They had no way to keep the battery charged!!!??? and the wideband O2 was wobbling around in the dyno headers like a cock in a sock. So they kept complaining why the tests weren't repeatable!? Morons!
Anyway I suspect this little 302 will make around 500hp once in the car.
