Compression Question
Whats the highest that one would be able to go on the compression ratio? I've heard about 11.5:1 would be the highest for only 91 octane. Could I go up to 12.5:1 and still be on 91? Would have to retard a whole lot?

Around 12:1 on 91 octane, you'll still have to retard the timing some to avoid detonating.
