My factory gause actually reads VERY slightly higher then my aftermarket.
So I have the factory guage - attached right above the oil filter in a T-fitting that feeds oil to the super charger, and a mech. Autometer attached into the top of the block in the rear.
I Run 10-40W Dino
Mech gauge shows about 2-3 Lbs less then stock gauge.
At startup I'm around 80PSI, Once oil temp gets above 180 to starts to drop off slightly. Sunday is was 82degrees out and I was hot laping the car Oil was about 195 degrees and pressure stayed above 65PSI.
I don't know if I would go lighter on the oil, unless something like 5-30W with a bottle of STP?
