I have been searching and I get conflicting results.
I just put a whipple on the 06 gt. ( I will get it dynoed and give everyone A comparison of the roush M90, vs the Paxton 2200 vs this Whipple in a couple weeks )
anyway I want to have a second pulley when I get to the dyno. I have the 3.25 on it now and I get about 10 psi at 6k.
The internals are forged so after an inital dyno on this pulley I want to up it to about 15 psi.
Can anyone tell me what pulley to use for this.
