Standard oil pump vs High volume.

[rebuilt]

Gotta buy one whats the advantage of the high volume?

[JoeliusZ28]

benefit is kind of obvious, it flows more volume? not trying to be sarcastic... just saying.

be sure not to use a high volume pump on a stock pan because you can suck it dry. it is ok to use a high pressure pump however, or the $3 pressure-relief spring upgrade.

Pretty sure you can run a stock pan with a high volume pump. There are guys doing it, including me.

Be careful is all i have to say. I think its about 50/50 with people running high volume pumps and stock pans. A local mechanic told me i could run one if my engine was clean with no sludge in it, but then there are guys who have lost engines on ls1tech i know.

FWIW, I've never actually met anyone who's sucked their pan dry with an HV pump, but I
have met many who have been running them for years without issue.

Having said that, I don't see any huge advantage to an HV pump, it seems to me that it would only cause more drag on the motor.
