Update (3/14/14): Effective immediately, per Mo-Kan and /or IHRA rules the following devices are not legal for bracket racing at Mo-Kan.
All Davis Technologies traction control devices.
And #7761 add on module.
Super Pro (0 - 8.00 -- 1/8 mile)
No down track stutters. All wiring to trans brake and delay box must be identifiable to tech inspector.
No-Electronics (0-10.99 -- 1/8 mile)
No delay boxes, delay boxes must be removed from car. Throttle stop controllers and automated throttle stops must be disabled. Pneumatic/electric shifters allowed. Any device that relays vehicles on track performance, other than OEM, is prohibited. Line locks on non-driven wheels only. Line locks may not be used as a launching device. All wiring to line lock must be visible and traceable. Transbrakes may not be used as a launching device. Two or three step rev limiters are prohibited. Single stage rev limiter is acceptable but cannot be used as a launching device. Clutch launched, stick shift vehicles may use line lock on starting line to prevent vehicle from rolling. Clutch launched, stick shift vehicles may use single stage rev limiter to control starting line RPM. Tree blinder is used for No-E eliminations.
Sportsman (11.00 - up -- 1/4 Mile)
11.00 and slower dial. No delay boxes, delay boxes must be removed from car. Throttle stop controllers, pneumatic/electric shifters and automated throttle stops must be disabled. Any device that relays vehicles on track performance, other than OEM, is prohibited. Line locks on non-driven wheels only. Line locks may not be used as a launching device. All wiring to line lock must be visible and traceable.
Transbrakes may not be used as a launching device. Two or three step rev limiters are prohibited. Single stage rev limiter is acceptable but cannot be used as a launching device. Clutch launched, stick shift vehicles may use line lock on starting line to prevent vehicle from rolling. Clutch launched, stick shift vehicles may use single stage rev limiter to control starting line RPM. Tree blinder is used for No-E eliminations.
There is no break rule for bracket eliminations. If you win a round and cannot return for the next, you will receive points and/or money, if any, as if you appeared in the next round and lost.
Car & Driver
A single car may enter once in any class it is legal for. A driver may enter each class once. You must run the same car during eliminations that you start with. If your car breaks during eliminations, you cannot substitute it with another car.
Cars will be pulled with the first car on the left, as the staging director faces the lanes, running the first car on the right. EXAMPLE; if lanes 1 to 6 were used for Super Pro, as the staging director faced the lanes, he would match the first cars in lane 5 and 6. if lane 6 emptied first, he would then move to lane 4 and match it with the remaining cars in lane 5 until it emptied, and then move to match 4 and 3. When all but one lane empties, those cars will race each other. Fast car goes right the first round, left the second and so on. When there are 12 or fewer cars, parings are done from round sheet. With the first winner from the previous round running the second winner, and so on. If there are odd numbers, the bye goes to the best reaction time, provided they have not had a bye. Bye run runs last in the round.
After time runs, the computer will generate a PRO ladder based on reactions times. If there is an odd number in round one, the computer will pick the best R.T. for the bye run. It will be mandatory that the selected bike take the bye run. Just as we do with the cars, the fast dial will go to the right lane in round one, and left in round two, and so forth. After round one, parings will be from the round sheet, with the first winner running the second winner, etc., for round two, the round sheet will also be used to pair the loser's side of the bracket, from those that buy back.
In non paired rounds, all bye runs are potential. Bye runs for round one is given to the best reaction time from the official time run sessions. Bye runs do not carry. If there is no bye that round, a new bye is picked from reaction time for the next round. If you get the wait and see bye, and there is no bye, you can still earn it by having the best reaction time. One bye run only during eliminations, unless all cars still in competition have had a bye.
Staging, auto start, cross talk
Must courtesy stage. Auto start will be on at all times in Super Pro and No-Electronics. Deep staging is not allowed. Staging must be with the front tires of the vehicle only. There must be at least 3" ground clearance for all parts of the race vehicle as it sets on the starting pad.
If either of your stage bulbs are out when the tree activates, you will get a red light. The three bulb timer is also on in Super Pro and No-Electronics. Once your opponent has both stage lights on, and you have the pre stage on, you will get a red if you do not stage in a timely manner. If you have problems behind the starting line, your opponent will be given a single, once the starter has determined you cannot make it to the line in a reasonable amount of time. This call is the starter's discretion. For Super Pro, cross talk will be used. If you happen to be the fast car, and you want cross talk disabled, put an "N" after your dial.
If excessive braking causes loss of control, you will be given ONE warning. The second time will be a disqualification. This call is made by track officials only!
Disqualifications are made on a first or worst basis. EXAMPLE: Crossing the centerline is considered worse than a red light. Since we cannot possibly cover all situations that may arise during eliminations, it is the Race Director's responsibility to make a judgment on disputed calls. If it is necessary to settle a dispute, the race director will speak with the drivers involved ONLY. Not the crews, wives and/or husbands.
