Almost as good as having a friend with a lathe!

Re: AeroVee Performance (Cold Air Induction)

I wonder if we have a minor intake leak on the hot EGT cylinder. I'm going to reseal the intake.

Re: AeroVee Performance (Cold Air Induction)

Could it be the uneven EGT's are contributed to by uneven mixture caused by the elbo at the input of the carb? Could be, but it was like that when I had the RC-1980 filter too. It met it's demise as part of my conversation to the church of safety wire and other positive retention. http://www.sonexb...

Re: AeroVee Performance (Cold Air Induction)

Left rear. Left front is the second highest. I have one style TC on the left and a different style on the right.

Re: AeroVee Performance (Cold Air Induction)

I flew today, after my latest adjustment and it seems pretty good. One odd thing though. The EGT that is generally the highest is going to about 1450F in the climb, while the other ones are pretty cold. I'm seeing 1100-1200 on the cool ones and the closest one is a little over 1300F. If I enrichen t...

Hopefully none. Lots of leaks in the air filter shroud and the rubber strip is free to flap open. Mostly I'm shooting for fresh air.

Re: AeroVee Performance (Cold Air Induction)

Flight test results: still too rich. At full rich the engine was not happy at all. Leaned out and it smoothed out. But in a full power climb I was having a hard time adjusting the mixture so the engine was happy and the EGTs were below 1400F. I'm going to try another 1/4 turn lean.

Re: AeroVee Performance (Cold Air Induction)

It took about 3 adjustments, 1/4 turn lean each time to get it to run well on the ground. Next step flight test.

Re: AeroVee Performance (Cold Air Induction)

The 2.5 needle is installed. As soon as the air filter is installed I'm going to try a ground run. I did add some sealing to the air filter shroud. flap closed.png This is installed so the flap will open and prevent high pressure, or if a bird flies into the intake and blocks the scat tube then it w...
