. If you remember I do not have coolant temp reading right now, so I closely monitored the oil temp and kept the run short, but I was curious as to what I could run it up to. Thanks again.

My=20 prop is an IVO in-flight adjustable 45 to 105 % pitch range, so I guess = it is=20 pitched full fine at 45%. We also did a mild street port during = the=20 rebuild. The prop is, IIRC 66" per Velocity, Inc. = recommendation. (if=20 not 66 it is 68").

All=20 the best,

Chris

Chris, that is great power "out of the box" = with=20 the 2.17 redrive. My early engine and induction system was = humping to=20 produce 5000 rpm static with a 68x72 prop (2.17:1 gearbox). What = pitch=20 do you have on the prop? That will of course make a big=20 difference. But, regardless, that is a great start.

Congratulations

Ed

Subject: [FlyRotary] Static = RPM

Ok, I know I have read about this = somewhere,=20 but not sure where or what I read means, but I finally ran my engine = up to=20 full power and was wondering what kind of numbers I should be=20 seeing.

Even though I had some intermentant = wire issue=20 (SUPRISE) in that as I got over about 4500 rpm the rpm = would flash in=20 the hundreds and then go to zero. When I throttled back = to below=20 4500 ish, the reading came back. This happened a few=20 times.

However, later when I did = it, the readings=20 were better and I was able to run the rpm up to about 5500 rpm = at full=20 power on the Mistral Intake (so about 2534 rpm at the prop). = It seem=20 to reach full rpm at about 3/4 (to 4/5) of full throttle and then = mostly=20 stablized. Sounded smooth even though I am still running = rich. =20 It seems to run much better with the mixture at about 9 oclock and = bogs as I=20 bring it to the noon position. In auto tune it seems to = be=20 trying to lean but kinda slow and if I try to keep it at the 12 = oclock=20 position it seems too rich, so I think I will need to do some = manual=20 leaning and then go back to the autotune. I am idleing pretty = smoothly=20 at about 1000 rpm.

Is this RPM range acceptable? = Is this=20 good; bad? What should I expect? I was nervous to run it = up like=20 this, but I just kept telling myself that I am not gonna be throwing = a rod=20 or blowing a jug <g>. If you remember I do not have = coolant temp=20 reading right now, so I closely monitored the oil temp and kept the = run=20 short, but I was curious as to what I could run it up to. = Thanks=20 again.

All the best,

Chris
