The only thing you're missing is a hunchback and a lab coat. The pretty

(maybe using tranny as gear reduction?) cool with big fan. spin it at 1700-ish rpm the math: theoretical cfm=(c.i.d.*rpm)/3464 19.43 cfm=(39.6*1700)/3464 i'm assuming compression of 130-150 in the head.. total materials needed: 4 check valves 1 pressure cut out switch. 1 relief valve 1 5hp motor (230/1) 1 regulator 2 intake filters 1 line filter various fittings to plumb motor to tank. am i crazy or will this work? would a 5hp compressor spin this? if i used tranny as gear reduction, and put it in 5th gear, i would think 5hp would be enough to turn it over? would there be a ton of oil in the air? it seems like an ineffecient, single stage compressor to me. am i missing something?
