I don't think compression has a lot to do with it but more by choice unless it is gonna be strictly used for one purpose (NOS, Blower, Etc.). I have everything from 8:1 to 12:1 and the higher the compression the faster they seem to go. You just have to be careful on the timing issue or your day can be ruined in one pass.

I think the main issue is if your gonna use it as a daily driver because if you are then you won't care to ride around in a 16:1 car all day in traffic, etc...

Just my .02.
