00 GT Saleen Supercharged...Boost Pulley Question?

SuperCharged00GT · 05-10-2004, 09:05 PM

i am thinking of changing the boost pulley on the saleen supercharger...i believe it is running 6.5 psi at the moment i would really like to take it up to 9 psi, i have the saleen intercooler, motorcraft fuel rails, n all the other goodies that need to be changed for a supercharger...is it as easy as changing the pulley n instang hp or do i need to adjust fuel injectors, timing, and ecu?? thanks!

Well, what's your complete current setup?
I'm not on top of the game game when it comes to knowing the 99+ GT's returnless fuel system, but if I was throwing the 9psi on a stock block, I would run: 42# injectors, 90mm Lightning MAF, 255 fuel pump or equivilant for the 99+ cars (I think the returnless guys go with the '03 cobra pumps or dual focus pumps,) and a Superchips Custom Tuning dyno tune or at the least a custom chip. I would also think about locating the IAT (or ACT) sensor in one of the intake runners.
