Personally I prefer the added fuel mileage, we don't need more power.
On our tracks we generally agree that 9 minutes is repectable, assuming you have the power to clear the triple jumps. I am currently running the .21 in a 1/8 TT using the smallest ventury and generaly make a pit between 9.5 and 10 minutes, however I admit that my son gets almost another minute... Newer motor or better hands... Anyways there is a craze over here about some new motor creating 2.8 hp!! I would appreciate details on the wasp us spec power range, as the www nor the papers in the box give exact details. Thanx
