RE: Hot rodding a Zenoah GT80??
I had no idea it was for a war-bird. When H9 came out with my 33% Cap, they were pushing the GT-80. I put a BME 102 in the airplane that was 3lbs lighter and 20% more powerful. The BME has a bare weight of 4.0lbs. Plane balanced fine, infact to get it to fly the way I wanted it still needed a little tail weight.

not looking for 3D performance, but it's powering a 33 lb warbird that only has ground clearance for a 23" prop.
plane at best does a loop with no umph at the top

What exhaust do you have on your GT80. The factory cans are quite but cost 700-1000 rpm depending on prop.
Most hot rod tricks will add HP but will require more RPM, reduce power at the lower end and will have a narrower power band.

I tend to fly at half throttle most of the time and will go full throttle on a straightaway every once in a while.
I would like to have a decent top end for some speed but want to make sure it has enough power to muscle it out of any dicey situations I might get into.
This Terry?

It's got the factory exhaust on it.Was looking at Toni's 2 into one exhaust but don't know if the gain will be noticeable for my style flying.

I think that J&A Engineering makes mufflers for the GT 80. Way back when the Zenoah first came out Joe had a set of HP mufflers, a little noisy, but they actually showed a power increase over open exhaust (some tuning was happening)
Yes its Terry, cant stay away
