People used to run 40% all the time.
Fuel mileage is such an issue these days I don't think there is an advantage to it anymore.

Big trade off here. Ran 40% on a couple of occasions. On the plus side, definite difference in performance.........down side is the rod big end pretty much goes away in a weekend of racing.
