Rusty, you are right man just fly the airplane uncowled and it will cool. My oil cooler with the nice diffuser inlet duct and no cowl ran the oil very cool. Today I ran the with the cowl on. If anything you would think my inlet flow would have been better because all the cowl does is add a nice small bellmouth to the duct. My total exit area for radiator, cooler, and 2.5 in dia exhaust pipe is approximately 30 square inches. Ran 29.5 inches of manifold pressure for 1.5 minutes topped the 220 degree farenheit oil temp with 78 OAT. It was about 180 when I started the power run. Have not calibrated the oil measurement and it is the hot inlet side of the oil cooler. I know Tracy wants to measure the cool side and I have the TC clamped to the fitting but have not chased down where it reads on the monitor. Will do that before I run with cowling again.
Called the DAR today and FAX'ed my registration and Wt&Bal sheet to him.
Bernie, getting closer every day by exactly one day!

Charlie, don't think you missed anything! I kidded Rusty a long time ago about continually opening the intake holes to cooling systems rather than decreasing the back pressure of the radiators. I told him to just leave the cowl off and it would probably be fine except for a small item called drag! Look at Ed Anderson's installation, you can get you fist in the intake side.
Bernie, waiting on DAR and new fuel injector.
