General Rules

BODY: All replacement body parts must resemble the stock factory item they are replacing, however, they need not be exact, i.e. fenders may be wider to allow for bigger or wider tires. A stock appearing deck lid is defined as follows: The deck lid shall slope downward and the bottom shall extend furthest rearward. Deck lids where the top extends farther back than the bottom shall not be allowed. A fabricated deck lid should include a break in the rear plane. A deck lid is considered part of the car and must be painted. 

ENGINE: Contestants in weight to cubic inch classes must claim exact cubic inch displacement rounded out to the next largest cubic inch. No allowance for overbore. i.e. 131.6 = 132. If engine is changed during a race the competitor must report to TxPRA technical department supervisor before a run is attempted. The formula as follows can be used for determining cc's: Bore x Bore x Stroke x 3.1416. (example: 94mm X 94mm X 86mm X 3.1416 = 2387.289 cc's, or 2388 cc's) The formula as follows will be used to convert from cc's to cubic inches: 1 cubic inch = 16.387 cc's. (2388 cc's divided by 16.387 = 146 c.i.)

EXHAUST: All cars must be equipped with an exhaust collector or stacks installed to direct exhaust out of body to rear of car, away from driver and fuel tank.

FUEL SYSTEMS: All fuel tanks, lines, pumps, etc., must be within the confines of the frame and/or steel body. All fuel lines must be metallic or steel braided. A maximum of 12" total, front to rear of non-metallic or non-steel braided line is permitted for connection purposes only. Whenever possible, fuel tanks, and fuel lines, should be located ahead of engine. Fuel lines near flywheel bellhousing, & clutch or pressure plate components, must be enclosed in a 16" length of steel tubing. The use of Allen bolts to hold shield to engine not permitted. Bolts must be identifiable. Maximum depth of flywheel shield is 8 1/2". All bolts and covers must be installed prior to starting engine at any time, including warm-ups.

ALIGNMENT: Each car must have sufficient positive front end caster to ensure proper handling of car at all speeds.

BALLAST: Any material used for the purpose of adding to a car's weight must be permanently attached to the car's structure and must not extend behind the rear of the car's body, or above the rear tires. No liquid or loose ballast permitted, i.e. water, sandbags, rocks, shot bags, metal weight, etc. Weight boxes (2 maximum) made of 1/8" material may be constructed to hold small items such as shot bags, lead bars, etc., as long as box and contents do not weigh over 125 pounds. The box must be securely fastened to cars frame or crossmember with at least two 1/2" diameter steel bolts per 100 pounds.

TIRES: Tires will be visually checked for condition, pressure, etc., and must be considered free of patent deficiencies by the technical committee prior to any run. All street tires must have a minimum of 1/8" tread depth. Farm implement or trailer tires prohibited.

PARACHUTES: Any car exceeding 150 M.P.H. will be required to be equipped with a parachute from that run on. (Example: once a car exceeds 150 M.P.H., it will be required to have a deployable parachute installed on it before it will be allowed to make another run.) NO EXCEPTIONS! A parachute must be produced by a recognized parachute manufacturer. Tech inspector may inspect the condition for worn or frayed shroud lines, ripped or dirty canopies, and worn or ragged pilot chutes.

Parachute cables housing must be mounted solidly to the frame. The release cable housing must be attached within 12" of the parachute pack and in a manner that will allow the inner cable release of the chute.

GASOLINE: Gasoline as refined is a mixture of hydrocarbons. Gasoline is a good electrical insulator, or dielectric, and its relative effectiveness as an insulator is represented by its Dielectric Constant. The average DC for hydrocarbons which comprise gasoline is 2.025. This is defined as a reading of 0 with the Fuel Check Meter. The addition of compounds containing nitrogen and/or oxygen may produce a mixture with a DC greater than 0. Most gasoline will meet this criteria. It is recommended that unknown gas be checked before use in competition.

PROPYLENE OXIDE: The use of propylene oxide is prohibited in all categories.

THROTTLE: Regardless of class, each car must have a foot operated throttle incorporating a positive acting return spring directly attached to the carburetor throttle arm. A positive stop, or override prevention, must be used to keep linkage from passing over center and sticking in an open position.

FLYWHEEL SHIELD: (Turbo Cars): Must be made from 1/4" minimum thickness steel plate, securely mounted to the frame or frame structure and completely surrounding the bell housing 360 degrees. The flywheel shield shall not be bolted to either the bell housing or engine. The flywheel shield must extend forward to a point 1" ahead of the flywheel and 1" to the rear.

ROLL CAGE: All cage structures must be designed to protect the driver from any angle, 360 degrees. When driver is in driving position the roll cage must be at least 3" in front of helmet. The side bar must pass the driver at a point midway between the shoulder and elbow. All cage structures must have in their construction a cross bar for seat bracing and as the should harness attachment point and be installed no more than 4" below the driver's shoulders or to side brace. All chromoly welding must be done by approved heliarc process (TIG Welding). Mild steel welding must be approved wire feed process (MIG). Flush grinding welds not permitted. It is recommended that all cage welds be gusseted. All cars without the stock floor must have a sill to tie the front and rear of roll cage made of 1 5/8" x .083" Chromoly or 1/5/8" x .134" Mild Steel.



BURNOUTS: All pre-race burnouts are restricted to designated areas, using water only. No one may touch the car during a burnout. During eliminations only one burnout across the starting line.

A car must be backed up to the starting line after a burnout. A driver cannot turn around on the track and drive back to the starting line. Cars can be pushed back to the starting line after a burnout if they cannot back up under their own power.

STAGING: Once a car reaches the front of the staging lanes it must be ready to fire and race. The car must self-start. No push starts allowed. Staging must be done under vehicle's own power. Deep staging not allowed in PRO classes. The "Blue Light" will be used during eliminations. Both pre-stage and stage lights must be lit. Courtesy staging will be observed during eliminations. Both drivers must have their pre-stage lights lit before either may advance into the stage beams. Once both lights have been lit a driver cannot re-stage for a second time. Doing so will result in disqualification. All decisions of the starter are final.

TOW VEHICLES: All tow vehicles must have the number of the car they are towing displayed on the front windshield. This will allow the time slip personnel to quickly find the correct time slip and reduce traffic tie-ups.

RACE OFFICIALS: The Competition Director has the final authority on any dispute or interpretation of the rules. Any driver, or group of drivers, attempting to override the Competition Director will be removed from the program for that race with no refund of entry fees.

COMPETITION: All winners are advised that their engines will be checked for displacement prior to being awarded the win. All engines must be the exact displacement as claimed or smaller. If the engine is larger than claimed the driver will be disqualified even if the car has the correct weight for the actual size of the engine. Driver must proceed directly to scales after each round of qualifying AND eliminations to be weighed.
