REFLECTOR: Engine Ideas? Superior/Lycoming

[Richard J. Gentil]

Kevin,

I have posted about it a couple of times now, I was one of the first to 
put down a deposit back in June. Right now Superior is expecting to have 
XP-400s maybe by September. The SRE's will not have a deadline, since 
they do not have the straight XP-400s sorted out. Also, in order to get 
the 250hp, you need to run the engine at 2,900rpm.

Right now I am trying to find an IO-390X, since I am too far along on my 
build and I cannot wait another year + for an SRE.
