OB_OT: A few decades ago, the Fremont race track used to have a 1200cc aircooled "anything goes" class. Then they changed that to 1200cc aircooled VW "anything goes" when I was 1/3 of the way through building a car out of two Honda 600s. The Honda 600 resembles a Mini-Cooper, with 600cc 2 cylinder engine resembling a motorcycle engine, front wheel drive with a trailer axle rear end; ~36HP, but ~45 with the Hawaiian head and cam, plus ~10% more with some porting and polishing. By mounting an extra front subframe where the rear used to be, it was 1200cc, 4 cylinder (2 in each engine) >90HP, higher power:weight ratio than anything else in the class, much cheaper to build than any of the serious contenders, 4WD, 4W disk brakes, 4Wsteering (that REALLY takes some getting used to!) And street legal. almost.
