I do run on a small track. Maybe that's why I'm so amased when people get excited over 10 minutes of run time.

My point exactly bro


Its a little different when you get to a larger layout , more fuel flowing through the engine reaching higher rpm's and staying on the pipe . Runtimes decrease quite a bit , that's where the 6mm insert venturi and all that stuff comes into effect .


Happy motorin',

ok we haven't talked about this it all. Should I run a bigger venturi. I have a 70 foot straight, a bunch of turns and I think 9 or 10 jumps back to back down the back straight. I want to tripple one jump, but can't get enough power to do it. I have the pipe combo I want, but what venturi should I use. Right now I'm running the 6mm venturi. I usually end up in the B Main, which runs 20 minutes. I end up fueling least once.
