The dyno competition will be broken down into 4 classes Street Stock, Modified, Pro Street, and Pro Modified.
Each class will follow the same rules as for the track class breakdowns. In addition to those rules, the following rules will apply on the dyno.
1) Use of NOS (nitrous oxide) prohibited.
2) Each participant gets 2 pulls to produce their max TQ and HP. The maximum numbers will be used. (Example: If the max HP is from pull #1 and max TQ from pull #2.)
3) If the dyno has a malfunction or if the car downshifts a 3rd pull will be allowed.
4) No tuning will be allowed between pulls.
5) Torque converter locking is allowed as long as the person does not change any other transmission or tuning settings during competition (locked for HP and unlocked for torque).
6) A HP spike will not be counted as your highest HP. We are trying to achieve true actual performance numbers. Knowing how to manipulate a dyno and release the throttle at the right moment to achieve a HP spike will not be counted.
