Re: Oil Cooler: Type 3 Engine

["Keith Park" <TopNotchResto@worldnet.att.net>]

I disagree a bit with Jim here, the new engines start around 40psi at 70 on
a hot day cruising (~3400rpm) wander their way down to 20 or so when thier
shot.

Ive pushed beyond 80 PSI on a cold day with 30wt coming off first in the
morning.
