High volume /pressure oil pump Ford Kent

Recommended Posts

Is high capacity and high pressure oil pump safe for bearings? I sometimes read that too high a pressure eats metal bearing prematurely. Is the Burton High Power Pump High Quality?

No cooler, just base Kent Hybrid X-flow

All bearings are designed for a certain flow through them @ a certain pressure. Pressure before the bearing is determined by the restriction of the hole into it and flow is determined by the bearing fit / tolerance. OEM bearings will have design pressure between 30 - 60psi and at whatever the bearing fit is + some wear tolerance. The addition of a HP pump won't necessarily benefit or harm a bearing as no more oil can flow through it unless you change the previous parameters. It may improve flow to valve gear which tend to starve for oil when hot or used hard. Race engines on the other hand are built with slacker bearings to reduce friction (its a nonsense as there is no metal to metal contact to cause friction) but require the higher flow to 'fill' the bigger bearing gaps + use of coolers etc. increase pumping losses so higher pressure helps with that. IMO higher pressure / flow pumps are of no benefit to a std engine - excess pressure is just bypassed back to the sump ie. doesn't get used - just heated!
