Maybe if I try two pumps I can pick up some more speed. Worth a shot anyways.

Given there are a gazillion blocks out there to mess around with, I have tried a lot of different porting measures. Some worked, some not. I have not burned a lot of pistons, but I have burned a couple. Most of my burnt pistons result from failure in water pumps or to large a brass fitting that broke off. Smaller fitting with adequate diamenter is the way to go. The big blocky fittings will break sooner.

Most of the serious racers know basic porting and tall or short and how it reacts on race courses of different sizes.

I guess some new homework was just assigned to me this fall.
