C14 min. Don't ask me how I know... Engine sounds great though, bet it would idle a little lower than that...
Not to appear pedantic but I think Europe uses a different way to rate octane numbers. IIRC I think 100 octane Europe is equivalent to 107 (ish) Stateside. Still not enough IMHO though.
yep! i think 100 octane is around 106/107 US Gasoline .. idle is around 1300 RPM
