ShawnQ,
Forgot about the clutch part, not even sure I fully understand it. Motors I've done in the past were BDS 871's which was constant boost and a few eaton whipples which had the vacuum by-pass. If it is clutched is it always partially engaged? Usually a motor designed around a blower has lower static compression and is a dog without boost. I'm guessing it has some type of electric clutching based on throttle position and MAF readings. Anyone have a link to this style/type supercharger. Thanks.
