Engine and Transmission

8.2.1 Modifications

Body Work

8.1.2 Body Work

8.1.2.1 Cars must maintain the OEM look and feel and be clean, free of

damage and presentable for competition.

8.1.2.2 Aftermarket body panels, front and/or rear fascias, side skirts

and wings, etc are permitted; body work that is not designed as O.E.M.

or an O.E.M. replacement of the original make and model of the vehicle

must be approved by EVERGREEN DRIFT TECHNICAL MANAGER.

8.1.2.3 No vertical aerodynamic elements may be added other than, 2

(two) wing standoffs and 2 (two) wing end plates. The size of each of

these my not exceed 12x16 inches in size per unit (dimension, not

surface area). The installation of these devices may not obstruct the

view, from any angle, or operation any of safety device, signaling

light, indicator, or other equipment. No body or aerodynamic elements

above the door  line may extend wider than the wheelbase of the vehicle.

Electrical System

8.6.1 Master Cut-Off
A Master electrical cut-off switch, wired to completely shut off all engine and electrical system function (except for electrically operated fire suppression systems, if applicable) is mandatory and must mounted outside the vehicle, on the right side cowl just below the windshield and is to be clearly marked with the appropriate “OFF” markings. The electrical terminals of the cut-off switch and/or any relays used in the circuit must be sufficiently insulated.

8.6.2 Battery
The battery must be securely mounted and the positive terminal completely insulated to avoid contact with any other metal parts. Batteries may be relocated. If the battery is located in the drivers compartment, it must in a sealed box bolted to the unibody/chassis with the battery securely fastened inside the box and properly vented and drained.

8.6.3 Lights
All vehicles must have normally functioning brake lights, tail lights (rain lights), and headlights. A high mounted 3rd brake light in an area not likely to be damaged in a collison is reccomended. Competitors shall make best effort to repair lighs damaged during competition. Headlights damaged in competition will not prevent the competitor from taking competitive runs. Vehicles must have at minimum one functioning brake light for all competitive runs and is subjet to forfit if repairs cannot be made in time.

The use of electrical cut off switches, or any other device that renders the brake lights inoperative in any way, is strictly prohibited.

Fuel System

8.5.1 Fuel Cells

The fuel system design is free. Fuel cells meeting SFI 28.1 for FIA FT-3 are recommended. Fuel tank/cell must be separated from the driver’s cockpit by a permanently mounted fully sealed  .036” steel or .059” aluminum minimum thickness bulkhead.

The floor pan may be modified to fit a fuel cell and lines. Fuel cells must have a flapper valve installed to prevent spillage in the event of a roll over.

Fuel cells may be installed in the driver compartment of the car, within the confines of the roll cage structure. When mounted in the driver compartment fuel cells must be SFI 28.1 or FIA FT-3 or greater certiifed and contained in a .036” steel or .059” aluminum box in addition to the manditory sealed bulkhead enclosure.

8.5.2 Fuel Lines

Fuel lines and fittings must be high-pressure type and routed in such a way that do not interfere with moving parts and be securely insulated and attached to the unibody or chassis. No fuel lines may be routed through the driver’s compartment. Teams may install dry-break fuel-filler attachments in the rear quarter windows or into the rear windshield or trunk lid to facilitate re-fueling from outside the car. The fuel filler tube between the fuel filler neck and the fuel cell, or tank, must be bulk-headed with .036” steel or .059” aluminum and sealed. There shall be a flexible tube between the fuel filler neck and the fuel cell/tank to allow for misalignment of the tube as the result of an accident as well as a one-way “flapper” valve.

A positive locking fuel filler cap (no Monza-style, flip-type) must be used, and fuel pick-up openings and lines, breather vents, and fuel filler lines shall be designed and installed so that if the car is partially or totally inverted, fuel shall not escape. The cap, filler neck, vents, and all fittings shall be isolated so in case of spillage, leakage, or failure, fuel will not reach the driver. Fuel tank breathers must vent outside the car.

Window Restraints

All cars shall have a window net, the clear O.E.M. glass, or a piece of clear Lexan or other polycarbonate material, in place of the drivers front window opening whenever the car is on-track. All open top cars (i.e. convertibles) shall use arm restraints instead of a window or window net. Occupants may choose to use arm restraints in lieu of the required window or window net.

Arm Restraint Use

Arm restraints are recommended to meet SFI 3.3 and used according to the manufacturer's directions. Arm restraint use guidelines are;

  • Position the arm band just above the elbow and adjust to fit snugly.
  • Loop restraint tethers through the seat belt latch so that they are released when the seat belt is released.
  • Adjust the strap length to prevent the arms from going above the head when raised.
ProAm

Towing Apparatus

All cars must have a minimum (1) front and (1) rear permanently installed towing apparatus (eye, strap, cable, etc.) with a minimum hole diameter of 50 mm or 2”.

7.8.1 The apparatus shall be strong enough to withstand the weight of the vehicle being pulled from non-racing surfaces such as gravel traps, approximately equal to 5000 lbs.

7.8.2 Tow apparatus must be a unique-purpose device. Using other structures i.e; a wing, body panel, or wheel is not allowed. The use of factory “tie down loops” is not permitted.

7.8.3 Tow apparatus must be easily accessible if the car is stopped in a gravel bed without removal or manipulation of body panels or other bodywork.

7.8.4 Tow apparatus must not protrude more that 1” beyond the furthest forward or rearward dimension of the bodywork or otherwise are hinged and/or collapsible in order to create a blunt surface. If the towing apparatus is located more than 12” above the ground, it shall not be rigid enough, in the area between the structural part of the chassis and the bodywork, to cause any damage, other than superficial, to another car. Towing eyes that stick out of the bodywork shall either be hinged to create a blunt surface, or thin enough (1/8" max thickness for steel plate) that it will bend if it comes in contact with metal bodywork of another car.

7.8.5 Tow apparatus must be painted or the strap material woven in a color contrasting the body color.

7.8.6 Tow apparatus must be clearly marked with an arrow in a contrasting color to the body color by using paint or by using a decal.

Fire Suppression System

All cars must be fitted with a minimum two (2) lb. fire-extinguishing bottle mounted in the driver’s compartment within reach of the driver when he/she is in the normal seated position. The mounting bracket must be a quick-release type, and must be mounted so that it can be removed easily for label inspection and verification of full charge by weighing.

Mounting must be solidly bolted to chassis with minimum required hardware size utilizing a minimum of 2 independent bolts. If mounted to sheet metal backing washers with a minimum diameter of 1" must be used.

Acceptable extinguishants are:

  • Halon 1211, Halon 1301
  • Underwriters Laboratory 10BC ratedSiliconized Sodium Bicarbonate or Potassium Bicarbonate (Purple K)
  • Underwriters Laboratory 1A10BC Ammonium Phosphate/Barium Sulfate, or Monnex.
  • AFFF (Aqueous Film Forming Foam) or equivalent surfactant foam material have a 2.25 liter minimum capacity (by volume).

 

An on-board fire system may be used in lieu of a 2 lb. fire extinguisher. Any system must conform to FIA Technical List #16, or meet SFI spec 17.1. On board systems are required to have at least one (1) nozzle in the engine compartment and one (1) nozzle in the driver’s compartment. In addition, one (1) nozzle is required in the fuel tank compartment (trunk) if no Fuel Cell is used.
