question for supercharge guys
a friend of mine is trying to figure out if its possible to run underdrive pullies (pretty much the same pullies i have, underdriven water and powersteering pump pullies and only lightened alternator not underdriven)with his rotrex supercharger? apparently the company says that it will throw off the speed of the blower and will be a negative affect on the boost. but i was always under the impression that with pullies on a normal setup the speed of the belt, and the crank is always the same regardless to what the accessories are driven at. is this true? will pullies cause the blower to run at a differnt rpm?
and my friend says thanks
