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


The Euroepan 98/99 octane is about 93 octane US. European gas is rated as RON octane, while US is (RON + MON)/2.
Race gas is available, and it must be unleaded, we are using VP MS109 at the track and regular 95 in the street. Was a bit difficult to obtain MS109 in the states... The last barrell I bought cost 26.7$ a gallon. Dirt cheap!
