Oil pump

["Tom Phelan" <tomph@ispchannel.com>]

Hi All,

Got a question for you racers out there. While checking over the oil pump on
a 2L race engine I'm working on I found a 3/8" stack of washers in the cap
for the regulator spring on the side of the pump. I assume this was done to
raise the oil regulator/bypass opening pressure to a higher lb/psi. Anyone
ever heard of doing this? Any comments on the pro's or con's? What is the
normal pressure at which the bypass is activated?
