Here's a picture of my mechanical throttle linkage mocked-up with wooden dowels. Since I have quite a range of adjustment at the gas pedal with this set-up, I'm looking for recommendations as to a good length of travel for the gas pedal. Do any of you have preferences? Given the high horsepower and low weight of these cars, I'm thinking more travel is better, but I don't want it to be too much. I'll tweak it once it's in go-kart stage, but I'm looking for a suggested starting point.
