But we have allot of pulleys to test with and I will report back the best combination and configuration for this setup. I really hope to make about 17psi but i dont know it will be that high since my engine flows real nicely with a lower ported intake manifold and full Motordyne LongTube headers and cat back exhaust. I have no cats on my exhaust system. It will come down to the whole argument of flow vs PSI so all I can do at this point is test and hope for the best.
