I'm putting my 89XR7 back together, and I'm wondering how much overdrive I should run. I got a 94/95 blower, and I took it apart and ported it and the inlet pretty heavily. I also have a FMIC, cam, ported stock valve heads, and some 42lb injectors that will be going on the car. Right now the blower has a 10% pulley on it, but I'm wondering if that will be enough, or should I get a 5 or 10% JS pulley too?
Oh, and the bottom end is stock with all new bearings and rings, and some MLS head gaskets.
