Last weekend at OSH I spoke to Continental about an IOX-370. I'm leaning toward that engine selection. JB offered a nice show discount as enticement. I want dual PMAGS and they are offering the Superior cold air sump so that is all perfect. My delima is which compression ratio should I pick. There is 8.3 with 187hp quoted or 9.6 which some have said is over 200hp. The cost delta isn't very much at a few hundred dollars. So the high compression option is a pretty good bang for the buck. When I was looking at an IO-360 I had set my compression ratio limit at 9:1, but that configuration isn't offered in the IO-370.
I'd like everyone's comments on any concerns I should have with such a high compression ratio. This does include the counterbalanced crankshaft. I'm feeling like I should be more conservative and go with the 8.3 but on the other hand...
