Oil Temperature

It's interesting that Scott said relocating the muffler only gave a 7F improvement in oil Temp. Sometimes I entertain the idea of water spray like they use at Reno. At least it would be a solution for climbs in PHX during August!😁

"RV-12 contrails" (instead of smoke...lowers oil temps and eco friendly too!)

Al Gore would approve!😁

Bahapilot, check your pm's

Hey Dave, I do have your cowl mod. I misspoke in my original post when I said Bill's cowl mod. It definitely is yours. Thanks, so much. That really did help a lot, and I have never seen temps in the yellow. I am much too watchful to allow that to happen. From seeing the posts here, I have been a bit too cautious, and I plan to raise my personal oil temp max closer to book numbers. I guess, as long as I never see the oil temp in the yellow, I will consider it good. Thanks again for sending me the details on your cowl mod. That certainly made the job a lot easier..........Tom

What would really be interesting would be to know if the relocated muffler also lowered the temps in other areas within the cowl, such as the areas by the carbs, and the firewall shelf, where the voltage regulator was originally installed??? Lowering the muffler could reduce fuel temp, and have other multiple advantages, as well..............Tom

FWIW Last summer I was running high oil temps with ambient temperatures in the 80's on climb out. I considered moving the oil cooler but since my prop pitch was more cruise than climb (about 4850 rpm) I decided to change the prop pitch first. By changing the pitch to get about 5200 rpm on climb out my oil temps have stayed below 230 this summer. The trade off of a lower cruise speed and lower fuel consumption was worth it.
