Hello everyone,
I made my first flight today, with a new engine that I need to break-in. It is a 180 hp Superior IO-360 with vertical induction, one slick mag, and one P-Mag. I was a little concerned about some of the temperatures I saw today in the 56 degree air and wanted to get some opinions about whether or not I need to make any changes.
The CHTs in my front two cylinders, #s 1 and 2, were running hotter than 3 and 4. When I first started my climb at full power I was at about 29" and 2660 rpm according to my EFIS. The CHT for cylinder 1 maxed at 432 and #2 maxed out at 429. #3 was at 403 and #4 at 398. My IAS at the time was about 125 knots. I pulled the power back to 24 squared and got my airspeed up to about 150 kts. The CHTs then went down 384, 397, 370 and 362. I have the vertical plates that come with the Van's firewall forward kit attached to my baffles right in front of cylinders 1 and 2. I'm considering removing those plates to let more air by those cylinders, but I've also been told that new engines tend to run hot. What do you all think?
The other question I had was about my oil pressure and temp. My oil temperature climbed to 200 degrees in the 56 degree air. My oil pressure at max power was in the high 70s. A local builder suggested that the pressure should be higher and the temperature lower. Once again, what do you guys think.
Thanks for any suggestions,
