Is anyone using a Procharger & a underdrive pulley system? I have saleen pulleys & have a Procharger on the way, I am wondering if the S/C pulley will mount to the balancer from Saleen.
with prochargers inset crank pulley it's been found a aftermarket ud pulley doesn't fit.
If you have a standard saleen pulley, I have seen numerous saleen owners with prochargers and I have not heard they had issues with the pulleys at all. That could be good for your application.
The idea of underdrive pullies is to slow down the accessories causing a few hp to free up. When used collectively like with CAI, tune, lightweight driveshaft, etc.. collectively the mods give a little extra power. Going with a blower is a whole different animal where it's gains far outweigh the concept of freeing up a little extra hp, not to say you wouldn't notice a gain on a dyno graph.
