I have a k20z1 in my ep3, with the A3 crank pulley. I am looking hard at the ct supercharger, and I wanted to know what size of pulley I would need for it to run around 8 psi of boost. Or maybe they already come with the proper size for my goals, I don't know, and Havent been able to find anything exactly with searching
I'm running the Pulley Boys 3.0 which is good for 10 psi. If I'm not mistaken, the 3.15 is what you're looking for.
Thats too small- he has a k20 with a bigger crank pulley. A 3.8 or 4.0 should be around what your looking for. If he had the smaller crank pulley from the z1- the 3.15 would work.
