[punker69q]

does anyone have a reliable source for the octane rating needed vs cool head volume for a 265r? I know their is alot of factors involved, but an estimate could help me.

I was wondering this also, Im gunna give a shout to LRD and see what kind of information they can give me, about switching back and forth to premium and race fuel/AV fuel.
