Folks,
I am soliciting opinions on the 400hp direct drive conversion to the
680F/FL/FLP.
My only experience of (roughly) the same engine was on the 400 Comanche and
the Excalibur conversion to the Queenair A80, neither were particularly
happy experiences, with quite a few problems with a big spread of CHT.
Regards,
Bill Hamilton

Bill,
Admitting no first hand experience, I did watch my mechanic/restoration guru Richard
Cam dial in a set of Gami's on 2 different QueenAirs. The temp problems
were eliminated, and the fuel flows reduced by 10%. It's still underpowered,
but not the problem it once was. The fit of the cowlings, and baffle seals
got a lot of attention as well. While the Gami's have not been fitted to my IGO-540's,
they have indicated they will work with me to fit a set. He's in St.
Augustine (Aeroquest Services) if you want the report first hard. He has a
lot of first hand experience wit the Mr. RPM conversions as well.
Good Luck
C
