Pro Comp

This class caters to no box bracket and street cars running 7.50 to 9.99. You get 3 qualifying attempts on Saturday, a 4th qualifying attempt on Sunday and eliminations on Sunday. You don't need to be at the track Saturday to race on Sunday. Rules are pretty simple and are as follows:

Class Description:

- The Pro Comp class was designed for all vehicles and trucks that run 7.50 to 9.99 seconds in the 1/4 mile. Open exhaust and vehicle lettering/decals permitted.  Dragsters, Altered & Motorcycles are not permitted. The "Pro Comp" class will be run on an Open Comp format with a 1-tenth (1/10th) breakout. What this means is, you get 3 rounds of qualifying. You choose your dial-in for eliminations. This time will be yours throughout eliminations (IT DOES NOT CHANGE).

Qualifying:*

The best reaction time is the #1 qualifier, you will then be put on a Sportsman ladder for eliminations. *There will be 1 (one) qualifying session on Sunday morning of each event for Open Comp and Pro Comp only. Racers in these classes will not be required to qualify on Saturday if they so choose. All racers will be required to pay the same entry fee regardless of whether they participate in one or two days of the event.

Class Guidelines

Rules & Regulations:

- Pro Comp is based on an Open Comp format, which uses a " 5/10ths Pro Tree" start system. Any "door slammer-type" vehicle is permitted. Any modifications, any tires, any vehicle weight, or power adders are permitted. Trans-brakes and 2-steps are permitted. Delay boxes, Throttle-stop, crossover boxes, or any "reaction-time related" electronic aids strictly prohibited.

E.T. Limits:

- The fastest qualifying ET permitted in the Open Comp class is 7.50. Any qualifying pass faster than 7.50 will be disqualified and will not count. Competitor will be permitted to requalify (if additional qualifying rounds are left) slower than 7.50. Competition will be regulated under standard IHRA "First or Worst" competition policy during qualifying and eliminations.

Deep Staging:

- Deep staging is permitted, however not advocated. If you plan to Deep Stage it is strongly recommended that you boldly display the words DEEP on all four windows, in plain view of the starter. It is always the driver's responsibility to stage the vehicle prior to the tree being activated. In any event, the driver must be prepared to leave as soon as the final stage light is lit.

- A competitor with the words DEEP displayed on the window is not necessarily obligated to deep stage. As well, the starter is not necessarily obligated to wait on a driver to deep stage, even if the words DEEP are displayed on the vehicle. All drivers must be prepared to leave as soon as the final stage light is lit.

Tow Vehicles:

- Pro Comp does not allow tow vehicles of any sort in the staging lanes. You can tow your vehicle back to the pits at the conclusion of your run after exiting the racing surface.
