I bet if you used the stock muffler with the carb bored to the standard ventury size no one could tell or would be concerned if it didn't turn over 17.5k How much did you bore out the exaust tube? Is it noticable? I like this motors configuration for SSC because it's harder to tear up in combat. It's muffler is behind the piston so it's less likely to get banged up in a midair. You can deflect the exaust downward so that its blows out the bottom of plane while keeping the engine upright (easier starting) and the needle valve is less suseptable to breaking off because it is angled back. If AP engines did thier homework and put a standard carb barrel on there this would be a very competative engine in SSC and some of the big boys would be using it. It's got duel bearings and the ports on the sleave are huge so it can pass a lot of fuel mixture through the engine. I will never go to the national events as My wife won't let me get too far (she holds our two small children over my head), but our club does a lot of SSC and we are not concerned with the specifics of motor modification as most planes are fairly equal in performance (mine included). If I only bore your carb to the standard .15 size it should be 17.5k (mine is a little bigger than the magnums and LA's) and probably no one would care (heck they don't care now!).
Anyway I live in the northeast part of Louisiana so I'll take you up on your offer. Email me your email and we'll exchange money and motor.
