after taking a tour of CMW who makes race oil for NASCAR teams among others I would ask Ron or Scott at CMW about their products.
FRI did something with oil pumps, I think they mostly deburred and cleaned it up a bit. Might want to read up on it on thier web site. -R
sweet even at the 800crank hp lvls?? Also what do you guys believe is the thickest oil that pump can handle?? Any ideas??
