just a thought the more power the harder to turn fast lap times. thats why most of us run 21's in our truggy's. back in the day the stock 2 wheel class carried more corner speed than the mod class. although if you dont care about racin the extra power is alot of fun when beatin up on your buds. i think jimbo,john,cory and i had more fun indoor beatin on each other on friday night practice nights than chad ever had fertilizing chickens.
