For those still interested,
After another 25hrs with the Show plane oil cooler configuration, I am seriously impressed. I've had no oil temps above 200 and I've pushed the engine hard for the last week. Im in SOCAL, so the Santa Ana winds have been blowing and I've had 85 degrees air temps at altitudes (around 6K) and the oil always settles down to 180 degrees. Pushed out the other day with 100 degrees on the ramp, typical fuel boiling during taxing, oil temp around 190. Took off with hard climb, oil temp goes up to 200, piston squirters keeping CHT's below 350 and leveled off at 6.5K. I pushed a 90KT climb (2000+ foot/minute climb) all the way. Couldn't get oil temp over 200 and I was trying. On the other side, around 7:00 am, I ran the San Diego bay bridge/San Diego coast route at 500 ft and oil temp leveled at 178 degrees. So I'll probably have to block off during winter months but I can live with that. Conclusion: I have full use of my power (200hp) during extreme heat events. Best modification that I could have made, this was after checking all baffling, leaks, etc...Again, my shout out goes to Donny Eccker for the install. So those that have heat trouble with Angle Valve, 200 hp engines and can't use all your power due to temps, please consider the Show planes engine mount solution. No long 3" or 4" tubes trying to direct air to the back of the firewall mounted oil cooler, the show plane sits back about 45 degrees off #3 with rubber seal to allow for the violent engine shaking that Angle valves are known for during start up. Happy camper here......
