I agree with others, 500 is too hot. I know that's Lycoming's red line but most people think that's just too high. OTOH it will be tough to break in a new engine and keep the CHT's below 400. But below 430 is certainly doable, and lower on a cool day or as the engine runs a few hours (shouldn't take more than 3 or 4 to see CHT's drop). Run full rich, as fast as you can (minimize climbs), stay low where the air is denser, reduce RPM (that doesn't help with break in anyway). If there's one piece of advice I'd give to new owners with new engines, it would be: "Forget the air dams. After break in decide if you want them, and how big". -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=374065#374065 ________________________________ Message 13 ____________________________________ Time: 07:01:37 PM PST US Subject: RV10-List: Overhead Air - Bulkhead Penetration From: Phillip Perry What sized holes has everyone been punching through the bulkhead for overhead air? I've got the typical dual NACA setup on the sides feeding 2" tubing to the bulkhead. I'm tempted to drill a hole in the neighborhood of 3/4 to 1" in size and let the 2" tubing feed air through those smaller holes. Has anyone done that and how much air are you getting? I'm not a fan of knocking a 2" hole in a 3" bulkhead.

I will have to ditto Don=99s comments and suggest you use what ever flight technique is necessary to keep those temps significantly lower while you work out the cooling issues. My cylinders have never seen more than 430 on the hottest even at ISA +30F climb conditions out West. Good luck.

The Aluminum starts breaking down at those temps.... Questions: Do you have a stk Vans cowl? Plenum? I would suggest you put the wheel pants on immediately... that will enable you to climb and cruise at a higher speed, which will provide more cooling. Also, pull back the rpm's and mp a little and keep those temps under 430 in climb, and 400 or so in cruise... optimally 360 to 380. Please keep us informed.... talked to one of our RV guru's here, and he agrees totally.
