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?
