GENERAL RULES
Any car that fits within the rules of this class is welcome to race. Any “unique or unusual” combination not addressed above can be considered for competition on a case by case basis – with a significant weight penalty.
All races will be run on a .400 Pro Tree; Courtesy staging will be in effect. All cars must stage on their own power. Deep staging is not allowed. All races will be run 1/8 mile. In the instance where there is a malfunction of the track equipment, the cars in question will be brought back up for a rerun (in a reasonable amount of time – at host’s discretion). Tuning changes are prohibited, the only changes that can be made are: refueling, changing nitrous bottles, changing air pressure in tires, cooling off engine, or other safety related issues.
All IHRA and local track rules apply for driver, and car to include use of an oil retention device.
All cars must be scaled when required. Failure to do so will forfeit/negate that run. Please contact Mike Garvin if you are unsure about what weight your car should be.
If the car you are racing is late to the lanes and arrives at the burnout box before you have prestaged your car – that car will be allowed to run. You will be allowed to back up and start your burnout again. If you have already prestaged and the other car is not present, then that car will be disqualified. In any other circumstances, if you have taken the tree – you have agreed to run that particular race as is. There are sometimes mitigating circumstances, these instances will be dealt with on a case by case basis.
All drivers, pit crew and family members will be expected to act in a professional manner. It is the driver’s responsibility to ensure that all pit crew members as well as family members adhere to this rule, any violation will result in disqualification and loss of entry fees. We reserve the right, as hosts of the race, to make the final decision on disqualification.
Under no circumstances are you to pull to the line without proper safety gear in place. This means EVERYTHING. Gloves, helmet, jacket, pants, harnessess, etc. This is for your own safety.
No infrared “cheating” devices are allowed on ANY car participating. If you have anything that extends from the front of the car in front of the tires, below the front of the car in front of the tires – or any thing that can trip the beams at the end of the track before the tires can. (This rule can be modified at group’s discretion)
Elimination
Racers will qualify then be paired with Sportsman Ladder.
The Sportsman Ladder is built on the concept of dividing the class into two groups, the higher qualifying drivers form the fast group and the other half of the class form the slower group. In the case of ET’s, the drivers with the fastest ET are grouped together against the drivers with the slower ET’s. The fastest ET in the fast group is paired against the fastest ET in the slow group. The second fastest ET in the fast group is paired against the second fastest ET in the slow group and so on. BYE runs are inserted in the ladders to match the best qualifier with a BYE run in the earliest round. The second best qualifier will get a BYE run in a later round if a second BYE is available for that particular ladder. BYE runs could apply to the third and possibly the fourth best qualifier in some ladders.
Tech
All engines are subject to valve angle, port location, and displacement verification at any time. Nitrous limits and turbos size will be verified before each event and at random during the event as deemed necessary by tech officials.
THE RULES MAY BE ADJUSTED AS NECESSARY IN AN EFFORT TO MAINTAIN PARITY
