Hi all,
My car is fitted with a stoker 302 giving 347 cu. inches.
I have uprated exhaust manifold. Same as a factory lightweight, and slightly hotter road cam. Net result, lots of torque and somewhere in excess of 320+ horses. Also oil cooler fitted.
Oil pressure in normal driving is generally rock steady around 50psi. However if I drive it at or over 3000r.pm. (roughly 100 m.p.h with my diff)in 5th for any period of time, I lose 3-4 psi at speed and around 10psi on tickover.
Now, is this just because I am useing so much throttle, to maintain this pace, or should I look at the cooling again?
Does anybody else see this effect, and if so have you taken any action, or, are you relaxed about it?
Thx
Nick G
