GENERAL REGULATIONS

Each car, regardless of class or category, must complete and satisfactorily pass inspection of a qualified scrutineer before being permitted to make a trial run or participate in any event conducted at an FIA licensed facility. (This includes private test sessions.)

Throughout this Appendix, a number of references are made for particular products to meet certain specifications (i.e.: FIA, SFI, SNELL, DOT, etc.). It is important to realize that these products are manufactured to meet certain specifications, and upon completion, that manufacturer labels his product as meeting that spec. Therefore, except as outlined under SFI or FIA requirements, any change to the product voids that certification; under no circumstances may any certified product be modified, altered or in any way vary from the as-manufactured condition; such a practice is in violation of the FIA, SFI, SNELL, DOT, etc., program and in so doing voids such certification and will not be accepted by FIA.

ENGINE: 1

1.1 COOLING SYSTEM

All cooling systems/radiators must be installed in the stock location for body style used. Front engine Dragsters must have system installed in front of engine. Rear engine dragsters with radiator mounted in front of engine must install a deflector from frame rail to frame rail and to the top of the roll cage. Portion above top rail may be width of rear roll cage bars. See 4.3 DEFLECTOR PLATE

1.2 ENGINE

Classes limited to automotive engines only unless otherwise stated under Class Requirements. Contestants in weight-to-cubic-inch (weight to cubic centimeter) classes must claim cubic inch (cubic centimeter) displacement of engine used; under no circumstances may claimed displacement exceed actual displacement by more than five cubic inches (81.9 cm3). No allowance for overbore; any part of a cubic inch (cubic centimeter) is rounded off to the next highest inch (i.e.: 301.2 = 302). If engine size is changed during a race, competitor must report to FIA scrutineer before a run is attempted. Crankshaft centerlines must not exceed 24-inches (61.0 cm) from ground in any class; except OEM trucks, max height 36-inches (91.5 cm) (inside). Engine must be mounted to frame by a minimum of two 3/8-inch (9.53 mm) diameter grade 5 (or Class 8.8) bolts.

Valve train must incorporate conventional automotive coil spring design; use of pneumatic-type valve trains are prohibited in all classes.

All classes, except ET cars slower than 10.99 seconds, harmonic balancer meeting SFI spec 18.1 mandatory. All cars with pressed-on front harmonic balancers must have such installed to prevent accidental loss (i.e.: drilled and bolted).

1.3 EXHAUST

If mufflers are used, they must be securely attached to exhaust system and car body or frame. Flexible tubing or "flex pipe" prohibited in all categories..

Consistent with its endeavors to maintain drag racing's acceptance as a recognized sport and recreation, FIA is experimenting with exhaust muffling devices and may in time require use of such equipment in certain environmental control areas.

1.4 FLASH SHIELDS

Carburetor inlet must not be openly exposed. In place of hood, carburetors must be equipped with a flash shield or velocity stacks which cover the top, back and sides, preventing fuel from being siphoned into the airstream or blown into driver's face. Additionally, any car that is driven, not towed, through the pits, with open stack(s) not protected by hood or scoop, must have screening installed on open stack(s) to prevent items from entering stack.

Gasoline is a good electrical insulator, or dielectric, and its relative effectiveness as an insulator is represented by its Dielectric Constant. The average D.C. for the hydrocarbons which comprise gasoline is 2.025. This is defined as a reading of "0" with the FIA Fuel Check meter.

Gasoline is tested and certified at FIA events through the application of various chemical analyses as considered appropriate by Fuel Check personnel. Gasoline in a vehicle may be checked before use in competition.

1.7 LIQUID OVERFLOW

All cars in competition with any type of water overflow capable of spilling water must have a catch-can to accumulate the excess liquids and not leak onto the track. Minimum catch-can capacity: 1 pint (.47 l). Catch-can must be securely fastened; i.e. bolted, clamped. Overflow may be routed into headers on cars that are supercharged or burn nitromethane or methanol.

Methanol is a clear, colorless liquid with a mild odor at ambient temperatures. Methanol is sold in two U.S. Federal Grades: A and AA. Either grade is acceptable for use in FIA competition, and racers should ensure that the methanol they purchase meets Federal standards of purity. The purity standards for each grade are shown in the table below.

Methanol is tested and certified at FIA events through the application of various chemical analyses as considered appropriate by Fuel Check personnel. To be considered legal, methanol used in FIA competition must meet the U.S. Federal standards of purity. Any deviation from these standards because of impurities (beyond the limits established in the U.S. Federal specification) in the fuel sample will result in disqualification. Since methanol is a hygroscopic substance, it readily absorbs moisture from the air which rapidly renders methanol illegal as a fuel for use in FIA competition. Racers are cautioned to keep methanol containers tightly capped at all times to minimize the absorption of water. Racers are encouraged to have Fuel Check personnel check samples of their methanol any time there may be doubt as to its purity.

1.9 NITROUS OXIDE

Nitrous oxide bottle(s) located in driver compartment must be equipped with a relief valve and vented outside of compartment. System must be commercially available and installed per manufacturers recommendations. All vehicles using a bottle of nitrous oxide must bear a mark in accordance with drawing n 23. The mark will be clearly visible and will be located in a place which is not likely to be damaged in the event of an accident and which is near to the competition number. External heating of bottle(s) prohibited.

1.10 OIL SYSTEM

Accu-sump, dry-sump tanks, oil filters, oil supply lines, etc., prohibited in driver compartment and outside of frame and/or steel body / fenders. Oil pressure gauge and line permitted in driver compartment. Metal or steel braided line mandatory, maximum 3/16-inch (4.76 mm) inside diameter. Power enhancing additives prohibited.

If used for installation, flat steel plates must be a minimum of 1/4-inch (6.35 mm) thickness and have rounded edges to prevent cutting seat belts. Under no circumstances can belts be installed with bolts through webbing. In all cars with fiberglass floors, a crossmember of minimum 2-inch (5.1 cm) x 2-inch (5.1 cm) x .083-inch (2.1 mm) wall thickness square tubing must be installed between frame rails for proper driver's seat belt installation. All cars in competition requiring a roll bar or when a roll cage has been installed or as outlined by Class Requirements, require a SFI 16.1 restraint system (See 10.5 DRIVER RESTRAINT SYSTEM).
