I've noticed that when I'm WOT down on the deck on a hot 95 degree day, my oil temps are still a bit high. DUH. So now I'm just being picky. Decided to add a row of Louvers to the lower cowling in an attempt to aid in pulling hot air out and away from the oil cooler. I have no clue if this will help but it sure looks good if I may say so myself. :) For now it reveted in for testing. Final configuration will be cleaner.
