All went well. Very stable with plenty of power. I’ll fly another week or so to ring out the engine and them put on the gear leg fairings and wheel pants.
Wings level and ball centered hands off – can’t ask more than that.

Congrats Carl.... we've got another 10 here (Dave Moore - Pecan Plantation in TX) that's being inspected tomorrow with first flight scheduled for Tues.
How were the temps w/o the pants?

500 for the hottest cylinder heads (#1 & #2) on the climb out (120 kts). All others were below 470 at the peak. All came down when I lowered the nose to a 130 kt climb. Second hop all were below 460, #1 & #2 again hottest. Oil temp peak at 226. OAT 80 or so. I have air dams in front of #1 and #2 that I knew were probably too tall. I just finish trimming them down and will test tomorrow. It took me a couple of tries on the 8A to get these the right height.
The significant drop in CHTs after the first hour is a hopeful sign that the engine break in is progressing as expected.

Carl, I ca't believe no one else has commented.... those temps are WAY tooooooo hot. 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.

Congrats!! I think most people are removing both cylinder dams. To get my engine cool and to balance properly, that's what I had to do, along with a second set of vents in the lower cowl to increase exit air and of course wheel pants. They all help!

Congrats Carl.
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".

Congratulations on the first flight. I will have to ditto Don’s 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.

Some follow up. Second and third flight this morning. On the second flight I had the air dams cut down to 1.6” at the highest point. #1 and #2 CHTs were much cooler than yesterday, but still hotter than the rest. On the third flight I just took the air dams off. Now #1 and #2 are the coolest, but just a little. #4 and #5 are the hottest but not much more than the rest.
Max CHT today was 440 after climb out from a quick fuel stop (yes – another overly aggressive climb), oil peaked at 226. At 4500’ with 24” and 2400RPM all cylinders now below 400, oil at 208. OAT 80+ and humid.
Of note the oil temps are lower than I expected for these conditions. I did a different cooler mount than Van’s so perhaps that had an effect. Next flight I’ll shut the oil cooler butterfly valve some to see if that puts more air over the cylinders.
Wheel pants and fairings go on next weekend. I’m hopeful the extra speed will further help.

Congrats Carl.... we've got another 10 here (Dave Moore - Pecan Plantation in TX) that's being inspected tomorrow with first flight scheduled for Tues.
How were the temps w/o the pants?

All went well. Very stable with plenty of power. I’ll fly another week or so to ring out the engine and them put on the gear leg fairings and wheel pants.
Wings level and ball centered hands off – can’t ask more than that.

Wheel pants = less drag and more speed. The plane doesn't work as hard and flys faster. You will notice some more improvement.

[quote] Some follow up. Second and third flight this morning. On the second flight I had the air dams cut down to 1.6” at the highest point. #1 and #2 CHTs were much cooler than yesterday, but still hotter than the rest. On the third flight I just took the air dams off. Now #1 and #2 are the coolest, but just a little. #4 and #5 are the hottest but not much more than the rest.
Max CHT today was 440 after climb out from a quick fuel stop (yes – another overly aggressive climb), oil peaked at 226. At 4500’ with 24” and 2400RPM all cylinders now below 400, oil at 208. OAT 80+ and humid.
Of note the oil temps are lower than I expected for these conditions. I did a different cooler mount than Van’s so perhaps that had an effect. Next flight I’ll shut the oil cooler butterfly valve some to see if that puts more air over the cylinders.
Wheel pants and fairings go on next weekend. I’m hopeful the extra speed will further help.

Carl, I ca't believe no one else has commented.... those temps are WAY tooooooo hot. 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.

500 for the hottest cylinder heads (#1 & #2) on the climb out (120 kts). All others were below 470 at the peak. All came down when I lowered the nose to a 130 kt climb. Second hop all were below 460, #1 & #2 again hottest. Oil temp peak at 226. OAT 80 or so. I have air dams in front of #1 and #2 that I knew were probably too tall. I just finish trimming them down and will test tomorrow. It took me a couple of tries on the 8A to get these the right height.
The significant drop in CHTs after the first hour is a hopeful sign that the engine break in is progressing as expected.
