[Fot] CR

[marty sukey]

What is the collective wisdom of the FOT masses as to how high of a CR can be
run on cast pistons? This would be Spitfire FWIW.  I am at 10.8:1,
intentionally kept it low because of the cast pistons.  I have had a
discussion with an engine builder telling me I can go much higher.  I am
contemplating bumping up to 12:1.  Before I blow something up I thought I
would toss it out for discussion. What say ye?

Thanks,
Marty (one race in and I already want to go faster) :)
