DRC Speedway Dirt Oval Rule Book Updated

Transcription

1 DRC Speedway Dirt Oval Rule Book Updated General Rules Race Format Heat Races: Each racer will participate in two rounds of 4 minute heat races. Round 1 heat races will be randomly sorted by the computer. Heat races will be resorted for round 2. All races will be a heads up start. Electric classes will use a standing start while nitro classes will have a rolling start. Main Events: All classes will run 4 minute main events. The six racers in each class with the fastest single round times will qualify straight into the A-Main. The next six will be in the B-Main, etc... Top 2 finishers in each lower main will bump up to the next higher main. Main Event Grid Lineup: All Main events will be lined up according to qualifying position. Lower Main Transfer drivers will start 7 th and 8 th accordingly. Track Procedures Turn marshals may not work on or repair cars. All cars must enter and exit the racing surface via the pit lane at all times. Any cars damaged and placed in the infield will remain there until that race is over. All drivers must turn marshal the race immediately following their race. All cars will be made available for tech inspection before and after race. Once a car has gone through tech before the race it must go directly to the track and not to pit area. All cars must have a personal transponder, or it will not be scored. Race Format 8 cars maximum per heat race. There will be no fewer than 2 rounds of heat races, unless poor weather or other uncontrollable circumstances arise. Scoring Issues In the event that laps may have been missed by the scoring system, please let the race director know IMMEDIATELY after the race in question. The race director will investigate the situation. It is a judgment call for the race director, based on several factors, including if the system has had issues or not, and if the race director witnessed the missed laps. If the race director does not witness missed laps first hand, the only other method to be awarded all appropriate laps is to have video evidence of the race to verify lap totals/timing. It is the racers responsibility to have transponders in perfect working order. The Race director will do everything possible to ensure proper scoring in any event, but a non-scoring transponder is not the race directors fault. Personal Transponders and ROAR memberships Personal transponders and roar memberships are required to race in any event at DRC Speedway. Best of the West Series Anyone planning to run a Best of the West Series event should review the latest BOTW rulebook to ensure the legality of their car for the series. Any BOTW legal car will also be legal to race here at DRC Speedway. DRC Speedway Rule Book Disclaimer DRC Speedway rules are based off of the Best of the West Series rules which use a modified form of DLMRA rules for 8th Scale, and a modified form of DODC Rules for 10th scale classes. There are a few minor additions to each of the respective rule books, and these additions are to help adapt the rules to our race program. If the rule book does not specifically say you can do something, either assume that you cannot, or ask an official for clarification or legality of what you would like to do. Any attempt to cheat the rules or to do anything that is not within the Spirit of the Rules may be deemed illegal at any time. No silicone capped or rubber capped tires are legal for competition in any class. 8th Scale Super Dirt Late Model Rules Section 1: Chassis 1-1 Must be 1/8 production based 4WD buggy drive train.

If you run aftermarket A-Arms on your vehicle, you must have stock replacement A-Arms present with you at all series races to prove that the arm is a replica of a stock component. Aftermarket arms with different lengths, wheelbase options, or any other change in design will not be allowed. If a racer believes another racer is running an illegal A-Arm, he can file a protest with the Race Director within 20 minutes of the protested parts use in competition. The protest fee is a $20. If an A-Arm is protested, it is the duty of the owner of the protested vehicle to supply an original A-Arm for which to compare. The Race Director will compare the parts with digital calipers, and make a decision based on the findings. If the A-arm is found to be a legal Aftermarket copy of a Production Part, the protested racer will get to keep the $20. If the A-arm is found to be an illegal part, that does not have the same specs as a Stock Production A-Arm, the racer who filed the protest will be refunded the protest fee, and the racer with illegal part will be Disqualified for the previous run. The purpose of this rule is to keep the class affordable. Same Make and Model REAR a-arms must be run on Left and right rear of your chassis, no offsetting. Same Make and Model FRONT a-arms must be run on Left and right front of your chassis, no offsetting. -75cc Max fuel tank size. -Must use 2.2 Production Truck Wheels and Tires. Tires: Any Foam Tire or Rubber Street Treaded Tire Wheels: Must use 2.2" Production truck wheels. Minimum wheel width is 1.875". A.125" tolerance will be allowed due to varying manufacturer wheel widths, but any wheel that is not within this tolerance will be disqualified. Maximum wheel width is 2". A.125" tolerance will also be given on Maximum width. Engine Rules: The SPEC Engine Options are: OS Engines.12 TG ($ street) OS Engines.12 TG Version II ($ street) Jammin.12 Red-Head Part #50126 ($99.99 street) Dynamite Platinum.12RE ($ street) - Engine modifications of ANY KIND will not be permitted. OPEN Engines: -Maximum Engine Size.12 cubic inch engines only -Engine modifications are OK -Weight penalty of 10 ounces will be applied if using an open engine. Minimum Weight:

6 Spec - EDM Bodies - Minimum Weight is 66 ounces without fuel. - Truck Bodies - Minimum Weight is 62 ounces without fuel. Open - EDM Bodies - Minimum Weight is 76 ounces without fuel. - Truck Bodies - Minimum Weight is 72 ounces without fuel Sportsman Sprint Car Rules: - Sprint Car bodies and wings must adhere to DODC body rules. Maximum 6 x 6 wing. - Any ROAR Approved 7.4 volt LiPo Battery. - Minimum weight is 52oz. Race Ready with Transponder. - All racers must use a ROAR Approved 17.5 turn Brushless motor, set to 0 degrees of motor timing. - All racers must use the SPEC Mandated Spur and pinion gears, under supervision of the race director. - All racers must use NON-BOOST ESC s or a profile set with zero degrees of motor timing. If your ESC has boosted profile capabilities, it must be set to a ROAR Spec/Blinky mode to indicate zero ESC timing Sportsman Sprint Car SPEC Gear Ratios - All participants will need to adhere to the following SPEC GEAR RATIOS: - Direct Drive Cars: Must run a 93 tooth 48 pitch spur gear, and 23 tooth pinion gear (4.04 FDR) OR Must run a 81 tooth 48 pitch spur gear, and 20 tooth pinion gear (4.05 FDR) -2.4:1 (B2,B3,CW) Transmissions: Must run a 88 tooth 64 pitch spur gear, and 52 tooth pinion gear (4.06 FDR) OR Must run a 66 tooth 48 pitch spur gear, and 39 tooth pinion gear (4.06 FDR) -2.6:1 (B4,HD) Transmissions: Must run a 80 tooth 64 pitch spur gear, and 51 tooth pinion gear (4.07 FDR) If you plan on running a vehicle with another type of transmission, let me know so I can calculate a proper gear ratio for you. If you have any questions feel free to ask. The reason some cars will use 64 pitch gears, while others use 48 pitch is to get the Gear Ratios as close as possible, to eliminate any advantage to running a particular transmission type. There is no advantage to running 64 or 48 pitch, as long as the ratio is the same. SPEC Tire -The Sportsman 17.5 class will run 35 Shore FOAM tires as a SPEC TIRE at all races. Regardless of tire diameter, the same SPEC Gear Ratio must be used. This will prevent racers from truing tires down small for more corner speed, as you will lose straightaway speed. As tires wear, corner speed will increase, and straightaway speed will decrease, resulting in a happy medium, no matter the tire size. -The race director reserves the right to slow down any racers car if needed to even the playing field. This is purely power related. I will make no attempts to limit handling. If a car is motoring past all others, It will be looked at to determine how to even the field, in the best interest of the class. Street Stock Class Rules Legal Chassis Platforms: Any production OFFROAD REAR MOTOR Buggy chassis, Current or vintage.
