    Is there a down side to running 11 mm on a Screw blower. I would like to run around 94% over on a standard deck Hemi what pully and belt would I need?

    we ran them on a screw blown 481x for years with no problem. you will have to measure the crank to blower centerline to figure out pulleys and belt length. RCD has a reference chart you can use.

    I run 11mm. Both on 100 tall and -500 BAE blocks. I can barely get a 1595 to work. For a 92 over, I forget the pulleys, but the top one was small and tough to get on and off. I easily run the 1705 belt and a wide varieties of ratios. With 92, you could run a pretty big top pulley and be easy on belts. I am far from a pro at this, but my belts last forever unless I am doing something foolish.
