What's your pump gas in Finland.
People run 93 octane up in the 12.s for compression

Its 98 Ron, some chart did show that it should be quite equal to 93 US octane. I have heard that some have ran high 11s comps with out any knocking issues but most street engines are made to run between 10-11 to keep it safe.
