CHP Oil Feed Pumps for Flatheads

It’s a fact: when pushed, those trusty Flatheads get hot, or very hot to put it bluntly, 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 substantially raises the capacity of the engines lubrication 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 this is a a true bolt-on unit.
