cool

thats cool .all i can tell you is that i put a 11/16 I.D. pick up in a std clevo pump and saw pump efficiency continue to clime all the way to 9600rpm crank speed. my H1 hydraulic studies told me that the inlet should always be 20% bigger than the outlet so i tried it.it worked.twin pickup would do the same.most of the keith black hemis i build have twin pickups
