SOUTHERN CALIFORNIA TIMING ASSOCIATION Presents
2008 Speed Trials RULES
*The rule change process is an ongoing one. Any active SCTA-BNI member may submit a request for rule change or clarification at any time by obtaining the proper form from the SCTA office or the registration trailer at an event. The form must be completely filled out and must be submitted by US or email to the SCTA office. The forms will be routed through the appropriate technical chair and committees for comment. When all appropriate research is completed, issues will be put on the agenda for discussion at the next scheduled rules meeting (usually in November of each year). Submissions received after September 1st of any year will not be considered for that year’s agenda.
SECTION 1 GENERAL COMPETITION REQUIREMENTS
If an appropriate class exists, a vehicle must run in that class. Any vehicle which is not legal for any class, but meets all technical regulations, will run for time only. No trophies will be awarded for ”time only” entries. Any questions regarding the proper classification of a vehicle should be directed to the class chairperson as listed in Section 17.
All protests must be made in writing using an official SCTA Protest Form. The completed protest form must be given to a Contest Board member prior to record certification or within 24 hours of the record being certified. All protests require a fee of $100.00. This fee is refundable if the protest is upheld, and if the protest is denied the fee is forfeited to the SCTA Treasurer. Protest forms will be available in the registration area.
Trophies are not awarded at all SCTA/BNI events. If it is determined by the Contest Board to award trophies, Record and Performance trophies will be sent to the winners by mail after the conclusion of a meet. Performance trophies will be awarded only to those entries that run within 3% of the record. When an entrant qualifies, but does not set a record, a performance trophy will be awarded. Trophies and record timing tags are awarded to the fastest record at the end of the event only. To obtain duplicate trophies for Bonneville records contact the SCTA-BNI office.
1.M DRIVER LICENSING:
All new cars/drivers/riders or drivers/riders new to the car/course may be required to make runs at less than full throttle or less than full course length. Successful completion of the license requirements shall include, but not be limited to, starting line procedure, course navigation and shutdown procedure, as determined by the Contest Board. ALL NEW DRIVERS/RIDERS SHALL ATTEND A ROOKIE ORIENTATION MEETING PRIOR TO THEIR FIRST COMPETITION RUN. The official conducting the meeting will sign a rookie sticker. Time and place for the orientation meeting will be announced at the start of the meet.
SECTION 2 COMPETITION REQUIREMENTS AND SPECIFICATIONS
Any internal combustion engine using either a two stroke or four stroke Otto cycle or Diesel cycle may run in any category, except for Vintage engine classes hereinafter described. In XF, XO, XXF, XXO, V4 and V4F classes, non-production engines or after-market blocks (even though they accept production crankshafts, cams and cylinder heads) may not be used. All other engines that transmit the power through the wheels only may run in Ù class. Only Streamliners and Unlimited Diesel Trucks may use more than one engine at the same time. For any engine to be considered for cubic inch (cc) requirements, the engine shall have contributed to the propulsion of the vehicle. Reaction propulsion engines are prohibited, except during exclusive meets.
In fuel classes, any approved liquid fuel may be used. Examples of approved fuels are: alcohol, hydrogen, nitro methane blends, nitrous oxide, and unapproved gasoline. The contest board may choose any test or combination of tests to assure liquid fuels used in ‘GAS’ classes comply with specifications. The tests may include but not be limited to dielectric testing, color comparisons, specific gravity and/or other testing methods. It is recommended that unknown gas be checked before use in competition. If the contest board establishes an ‘EVENT’ gas or diesel fuel, that product shall be used for record attempts where required by class rules.
SECTION 3 TECHNICAL
SPECIFICATIONS & REQUIREMENTS
3.A.3 Driver’s Helmet Support:
A side and rear helmet support system shall be used in all vehicles.
Forward movement: SFI 38.1 systems are encouraged, however, they shall be “engineered” as an integral part of the entire restraint system, inclusive of the seat, safety harness and roll structure.
Lateral movement: The structure shall provide restriction to lateral head movement of less than 2” per side by January 1, 2008. See Section 3.B.1.
Rear movement: See Section 3.C.
3.E DRIVER’S COMPARTMENT:
All driver’s compartments, driver’s positioning, and surrounding structures shall be designed to support adequate forward vision.
3.Q FIRE EXTINGUISHING SYSTEMS:
All cars and enclosed motorcycles must have a minimum of one driver-controlled fire extinguishing system using a minimum of 5 lbs. of extinguishing agent designed and applied to function as driver protection. Approved agents include Halon 1301, Halon 1211, DuPont FE36, and certain AFFF systems including Cold Fire 302, ESS Foam, Firefox Gem Foam and other Halon replacements certified by the manufacturer for use in a confined space. Dry chemical and CO2 may be used in the engine compartment only. The application and installation shall be in accord with the manufacturer’s recommendations and consistent with the size and shape of the driver’s compartment. The discharge rate should be designed to allow sufficient protection for the time it will take the car to stop from speed.
NOTE: Agent delivery lines are subject to dust and moisture clogging. Participants are responsible to assure that the fire system is full and operable before each event. Frequent clearing of the lines is recommended. Aqueous foam systems require that the nozzles be directed appropriately so that the agent does not impede the vision of the driver.
SECTION 4 DEFINITIONS
4.N ENGINE SWAP:
An engine swap is defined as when an engine from an engine design family that was not available as a factory or dealer installed option for a given vehicle year is used.
An engine design family is defined as engines which are made with the same basic material, have the same bore centers, crank shaft supports, deck height, cam location, head mounting, bell housing and engine mount patterns, etc. All OEM parts must fit the block without modification.
The use of an OEM or aftermarket replacement engine block from the same design family is not considered a swap. “Crate engines” are not considered engine swaps. Direct replacement aftermarket engine blocks are not considered engine swaps(Dart, World Products, etc.), if they meet the above engine swap design definition criteria.
An alternate spoiler design may be used. The spoiler must be a single surface with no side plates. The spoiler chord will be 10” maximum, measured on the top surface and at the center line of the car. The ends of the spoiler may follow the contour of the body but must not extend beyond the outside edges of the body at any point. When laid flat, the width of the spoiler chord can be a maximum of 16” wider than the outside plane of the rear tires.
4.EE STEP PAN:
The step pan shall be flat, parallel to the ground (side to side only) and no wider than the frame rails. A box may be constructed to enclose the portion of the transmission which protrudes through the step pan. The box must be rectangular in design, flat on the bottom, covering only the exposed portion of the transmission. The box shall not be tapered in any way; maximum clearance from the transmission shall be 1”. Chassis cross members are not considered as part of the frame for purposes of this rule. The transition at the rear of the step pan to the floorboard shall occur at a 45 deg. or steeper angle to be exempted from the definition of a belly pan.
All vehicles must have at least two parallel axles. The wheelbase is the distance measured from the centerline of the rear axle to the transverse center line of the front spindles. The wheelbase must be equal on the left and right sides of the vehicle to within 1”.
Streamliners are exempt from this rule.
A driveshaft is defined as the connection from the engine or transmission to the rear drive unit in a conventional front engine/rear drive configuration.
A bumper is a metal device that bolts to a car’s chassis to provide collision protection and may be removed in some classes. A bumper is typically 16-20” above the road surface. Bumper covers (thermoplastic body pieces on cars starting in 1978) are considered to be part of the body. The bumper cover cannot be removed or altered in shape and contour if not allowed by class rules. For the purposes of streamlining, any fascia covering the primary bumper bar ceases to be part of the bumper once above or below the primary impact absorbing region.
