CHP Oil Feed Pumps for Flatheads

It’s a fact: when pushed, those trusty Flatheads get hot, in fact very hot, which is also a result of low oil pump volume and pressure. The CHP pump is a once and for all cure for this problem. While looking stock on the outside it substantialy raises the capacity of the engines lubricate system with its internal modern gerotor technology. Oil pressure with hot engine is typically around 30 psi, instead of 5 psi with stock pumps. Feed volume is about 1 quart per 45 seconds, while original pumps need 7-10 minutes for this. As a result the engine runs smoother and cooler and can handle more power without problems. Installation is easy as it is a a true bolt-on unit.

Due to the substantially increased volume on the feed side it is recommended to upgrade the scavenger system with the CHP scavenger pump conversion kit.
