I'm = trying to tackle the oil cooling. Currently have a CX racing 11x9x2 (https://w= ww.cxracing.com/oil-cooler-kit/OC-248-30-AN10)

 

On a 30C / 85F day in FL @ 2200rpm = cruising

Coolant is 180 = outlet / 170 inlet 

Oil is 225-230 pan / 200 inlet / 215 = PSRU. 

 

I = use Valvoline VR1 20W-50 standard oil, and have synthetic sitting = on the shelf ready to go. Since we can't post much in pictures here, I = put a video on youtube of the setup. The cowl inlet is 4" and the = opening to the start of the wedge is 3". I added some turning vanes = to help the wedge shape send more air to the front, but didn't change = the temps too much.  

The only thing left to do is = increase the opening on the wedge. I could probably get away with a = 5" opening. If that doesn't work, then time to source out a bigger = rad. What sizes are you guys running?
