Any restrictions on that STC? I think I recall reading that the angle valve engine might be slightly less prone to detonation because of the combustion chamber shaft. But it's probably not more than 0.2 CR difference. Heck, I'm going to be running about 9.7 CR on my 356 Porsche on 92 octane auto gas.

You obviously have a fair amount of experience with 10:1 CR with apparently no problems with 100LL fuel at least and that will not only increase HP and BSFC and be especially beneficial at high altitude where the engine would not be derated by limiting MP. A 9.0:1 CR might be much easier to get approved. The only real practical solution to the replacement of 100LL will be with ________________________________ Message 2 _____________________________________ Time: 07:04:08 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: Project X plane Are the side air ducts made out of aluminum?

Dave closed out the opening on the bottom of the cowling where the old inlet was. The housing for the air filter is the last to be finished. I will send pics when I get some. ________________________________ From: lmassaro Sent: Sat, October 23, 2010 7:26:26 AM Subject: TeamGrumman-List: Re: Project X plane Nice pics...
