hey
im thinking of switching from VP C12 to an oxygenated blend this coming july in maine.
right now i run 135 mph in my class, and i want to each 140 without blowing up.
im very close to the limit on leaded gasoline. the VP C12 is giving me about all i can get from my motor and aero. i need about 4.5 percent more hp to get to 140.
what do i need to change in my tuning to accomodate oxygenated fuel? i have never run it.
im running 30 BTDC on timing, and about 145 or 150 on mains in my 35mm keihins (as if thats any help).
what has to change with oxygenated fuel? im looking up options right now.
