Well, I have to be cantankerous again (seems that's the only time I bother posting). 10% per point is very optimistic when you're talking 8:1 and higher. You'll probably get 10% (or more) going from 5:1 to 6:1. But I've heard more like 4% increase per point when you're in the 8:1 - 12:1 range. In fact, I read that in an article in a magazine (Car Craft I believe it was) wherein they actually tested it by stacking head gaskets to go a point at a time from 8:1 to 12:1. As best I recall it ended up showing about a 4% gain per point. I just have to say that in my opinion compression ratio is very over-rated for increasing power. As I alluded, I suppose it makes sense up to around 8:1 where you can get by on regular gas. After that, if it were me, I would take the extra money you would spend on race gas for a compression ratio increase and spend it on more bore and stroke or making your heads flow better or putting a better cam in it.
