Anything goes. Each vehicle makes two passes. The vehicle with the most

consistent two ET’s wins. This is determined by subtracting your faster

time from your slower time to determine the difference. Who ever has a

difference closest to 0.0 is the winner. If two or more people run the

same ET, then they will run off until winner is determined. For example,

vehicle 1 has ET’s of 4.0 and 4.1. Vehicle 2 has ET’s of 4.0 and 4.5.

Vehicle 1 wins because the time difference is 0.1 which is closer to 0.0.




Same as Consistency Class rules.




Kids will race atv’s, go carts, golf carts, etc. that can run no faster

than 6 seconds in 200ft. This is a consistency class so they will make

two passes, the vehicle with the most consistent two ET’s wins. This

will be ran side x side but consistency is the name of the game,

reaction time does not matter. Tether kill switches on all vehicles were

you are not seat belted on, standard kill switch on all others.
