I used to be one of those idiots... quite awhile ago.
Every time we've been to a road course we thru a mix of at least half 100 octane. The one time we did not (really just forgot and didn't drive by our usual gas station on the 5 where we'd get it) the motor blew up.
Good plan Robski.
My experience tells me that boosted applications have a much greater benefit and opportunity for increased power via octane boost than an NA motor.
