Re: Superchargers - Why?

Before I start with my normal answer again, I would like to know why you want a supercharger? Also, have you already done everything else (headers, cat-back, ported heads, intake manifold, etc.)? If you just want more power in general, then build the engine. Then, if you want more, add the supercharger. Now, where do you want the power? off idle (then a roots unit is what you want). If you want the power up top then get the ATI ProCharger (P1-SC). The major difference is when the boost comes on and at what psi. Roots will kick in at about 2200 RPM at 6 psi. Syntrifical (ATI, Vortech, etc) need to spool up a bit and max boost is found at max RPM (or until the bypass valve is activated).

Also, please search the archives for my previous posts. I've been there, bought the t-shirt and have the scars to prove it.
