I agree, 80lbs cold idle pressure sounds pretty high to me.

That's what the car has though.

Here's the oil pressure rundown, when I had the car running at oil temps above 200.

Cold idle pressure 80lbs

Idle pressure 30lbs at 200 degrees

Pressure at 200-2500rpms 70-80lbs

Cold idle pressure 80lbs.

This why I thought maybe dropping a weight to 10-40 from 20-50 might be OK.


I've always gone by the 10 lbs per 1000 rpm rule, and my engine was definitely running higher than that.
