What are the typical ranges for oil pressure (in psi) and oil temperature (in fahrenheit) for a stock redtop? And after a pretty hard and boosty run, how hot can the oil temperature get on average?

Thanks

(need this info so I can buy the appropriately scaled gauges)

I just installed my Defi Link gauges, so no idea if my setup is right on but I've gotten this so far -

Peak readings

Press: 90psi at WOT warmed upTemp: 190*F on hot day and LOTS of WOT(a few minutes of fairly steady boosting)

Average

Press: ~10-15psi at hot idle, 30-50psi in the midrange, 40-60psi at cold idleTemp: Takes about 4-5 minutes of driving to really pull the oil temp above 120*F. After about 10 minutes it normally sits at ~150-160*F with moderate to hard street driving.

I have a GReddy oil pan, and the temps are taken in the pan. Pressure is taken before the oil filter next to the stock pressure sender.

Those are about the numbers that I'm getting. A good rule of thumb for oil pressure is that you want about 10 psi for every 1000 RPMs that the engine is spinning.
