I agree with you, on the ground it is much quieter at idle vs. takeoff power level. I always use noise canceling headphones. It maybe my calibration point is biased as it has been many years since I have flown behind a Lycoming.

It does seem to quieten up a bit after I get away from the ground. I am also running two Supertrapp mufflers, the only mod I did to the mufflers is to replace the inside fiberglass material with stainless steel wool.

(You are not by chance the person who bought Any Parrish's plane are you?)

Ok, other things could make a difference too: interior, prop, headset, etc...
I've not heard mine from the ground either, but several people have commented that it a very distinct sound and they know when I'm flying around.

I built the plane, bought the engine from Paul K, radiators/cowling from Caleb L, and prop from Dee W.

So, to tie this to the original post, Paul and Caleb have already switched to a lycoming, and Dee is in the process. All 3 are on this forum. (might be some kind of hint there , but it was not due to failures)

I predict that the next Lycoming replacement will be an electric engine, not a better Subaru package.

No. Sarcasm in this case does not help.
The business model does not support such a contention as I stated earlier. You need to charge close to current market prices. At which point you lose the primary incentive for many to consider an auto-conversion. Price.

I'd prefer if we try to keep this thread on topic. I've started another thread here: http://www.vansairforce.com/communit...d.php?t=154316 for those wishing to discuss and explore Subaru power.
