Highest but safest compression ratio on 92 octane
I have a JDM B18C in my EK and I have the basic bolt ons, I have the Skunk2 manifold (waiting for installation), and I have my cams too (also waiting). I know the next thing I'm going to want to do is raise the compression and get hondata for my car.
I don't want to have to buy race gas for daily driving, but whats the highest compression that I can use SAFELY with 92 octane. I believe the compression ratio I have right now is 10.8:1.

92 octane. I've seen people run 12.5:1 CR on 92 octane with the Ignition timing set at dead center with no pinging. We are also at 4600 elavation feet which would cause more of a detonation due to thinner air as well.
