I have a Cobra running 8psi on a stock pulley procharger P1SC. I have a smaller pulley going on soon, but was wondering if it is worth upgrading to a larger TB over stock? I have heard both sides say yes worth it and others say the forced induction makes TB changes minmal to nothing?? Any ideas??

are you going to a single or dual blade, either way its going to help you out with your blower. how many psi are you planning on getting? my stock pulley on my p1sc was a 3.2" and you should have the same diameter crank pulley so i would figure if you want more psi you would get a 3.1''

4" ! big pulley, so youll def. get some boost from a 3.2" what i was asking was if you were planning to use a single blade or a bigger twin bore.
