Tim, the claiming rule is an attempt to level the playing field, motor-wise, by removing the incentive to spend many thousands of dollars part selecting a “super motor.” The theory is no one will spend 10 grand building a motor only to have it claimed for 4 grand after the race. One hole in the theory is maybe a huge budget racer/team won’t care….they just want to win super nats, and give no thought to a 6 grand loss…cost of racing and all that.

My question: how much performance variation is there in X30’s? I’ve always been under the assumption they are much closer out of the box than Rotax motors. Do builders part select and Frankenstein them to the degree that happens in Rotax?
