How are these oil pressure numbers?

88COBRA · 02-24-2002, 07:32 PM

I am collecting parts for my motor build, and I have a question. First here are my numbers:

All numbers are from a Autometer gauge
All numbers are on a completely stock motor
The motor had 10W30 when the numbers were taken
The block has 140K on it.

Cold idle = 50PSI
Warm Idle = 20PSI
When I give it gas it climbs very well, about 10psi for every 1000rpm.

Now, I have read on the net that my numbers are ok, especially if the pressure rises with the rpm.

Are these numbers ok for a supercharged car? I will be pushing 350-400rwhp.

Those numbers look pretty good for your mileage. My car has about the same mileage and PSI numbers and I'm pushing about 8 #'s of boost with no problems ( yet ).

Thanks for looking.

I will be doing a compression check this week, and if everything looks ok, the shortblock will stay in. If I think there is a problem, out she comes

I want to make sure that it will take 360-400RWHP. The block has been maintained since new, and I have taken extra special care. It may sound odd, but I change my oil every 3500-5000KM. I know this may be overkill, but better safe then sorry.

I will be changing all my seals, rear main, front cover, ect.. so I will be able to run synthetic oil this year. The blower should also prefer synthetic.

Any more comments? Keep them coming.....

Cold idle - 50-55 psi
Warm idle - 35-40 psi

This is on a 39,000 mile stock bottom end motor.

PS - I change my oil every 500-1000 miles! (just because it sits sooooo long b/t regular uses.)
