Dan Warner sent this along for everyone to read. Yes, it has been cleared with SCTA to post 'em here, so have at them. Remember -- these are just the rules that have been changed -- to which you'll have to add the 2014 rulebook to get a complete set of the rules.
Thanks, Dan. Happy Thanksgiving all.
SECTION 1 GENERAL COMPETITION
Where applicable, vehicles may be inspected with body panels off and on to verify the driver can reach all levers,
switches, etc., with the body in place. VEHICLES
PRESENTED FOR INSPECTION SHALL BE IN RACE READY CONDITION, i.e. RACE TIRES, SEAT BELTS, PARACHUTES, FIRE BOTTLES, ETC. INSTALLED. It may be required that the vehicle be presented for inspection on the ground. LIMB RESTRAINT SYSTEMS EFFECTIVENESS SHALL BE DEMONSTRATED. All technical inspections shall be made with the primary driver and alternate driver(s)/riders intending to operate the vehicle in attendance unless the driver/rider has/have already been safety-checked as noted in the Logbook and previously operated the vehicle at a SCTA sanctioned race meet. Inspector to have discretion in the matter. All vehicle technical inspections will be based on existing class record or the next higher class where a record exists.
In all cases, and regardless of other conflicting information on the entry form, it shall be the computer codes that determine what class the vehicle is actually entered in.
A FIRE EXTINGUISHER (4-lb. minimum), AND AN
OPERATIONAL CB RADIO (handheld CB radios do not qualify due to limited range and power), SHALL BE IN USE IN ALL PUSH/RECOVERY/SUPPORT VEHICLES. No race support vehicle shall leave the starting line without a working CB radio. CB radio microphones should be mounted so that the possibility of an “open microphone” is lessened.
SECTION 2 CAR COMPETITION
V4 (Vintage Four) class consists of any pre-1935 four-cylinder automotive production engine, up to 220 CID.Specialty heads are allowed.
V4F (Vintage Four Flathead) class consists of any pre-1935 originally designed flathead four-cylinder automotive production engine, up to 220 CID. The engine shall have been produced as a valve in block engine, the camshaft must remain in the same location as produced (in the block).Only flathead-type cylinder heads (valve in block) are allowed. No specialty OHV or OHC conversion cylinder heads are allowed.
The Vintage Four engine classes (V4/V4F) are allowed in Special Construction and Vintage Categories only.
For reasons of historical authenticity, vintage engine
modifications and equipment used shall be restricted to older technology levels, so far as is practical. Accordingly, in classes XO, XF, XXF, XXO, V4 and V4F, using Vintage bodies:
1.Turbochargers are not permitted.
2.Computers (2.Q) are allowed for data collection purposes only.
3.Electronic fuel injection prohibited.
4.Any ignition system may be used and may employ a crank trigger magnetic pickup. Timing may be "pre-programmed" or "mapped" and apply a preset timing curve and rev limiter. However, the ignition system shall not be "interactive". That is, the ignition system shall not make "variable real time" engine managementchanges while running based on sender or sensor inputs. For example: Manifold pressure sensor, O2 sensor, knock sensor, wheel speed or gear change sensors, etc. Entrant is responsible for demonstrating compliance..
SECTION 3 TECHNICAL
SPECIFICATIONS & REQUIREMENTS
3.QFIRE EXTINGUISHING SYSTEMS:
All cars and enclosed motorcycles shall 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 Gemfoam, Halotron or other Halon replacement 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 accordance with the manufacturer’s recommendations for 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.
SECTION 4 DEFINITIONS
A device on the upper portion of the body for the purpose of spoiling lift. The spoiler shall be mounted in the rear
portion of the body behind the rear axle centerline. Two different Implementation Approaches can be used but not mixed together, see Figures 9 and 10. Should a competitor wish to use a different approach to a spoiler implementation, that approach must be submitted to the Technical Committee for review and consideration prior to the race event.
Implementation Approach One:
The spoiler must have a continuous surface no wider than the outside edge of the rear tires. The maximum chord measured on the top surface at the center of the car can be 10 inches. A 1-inch tab or hinge can be added to the leading edge of the spoiler for mounting purposes only. A spill plate on each side of the spoiler is allowed and they must be mounted parallel to each other vertically and horizontally. Additional intermediate plates are allowed along the spoiler between the end plates. Care should be taken that the bottom of end plates (if used) does not interfere with parachute operation. The intermediate plates may be no larger than the end plates. They can extend no further forward than the rear axle centerline.Spill plates are allowed to be no more than 8 inches above and below the forward-mounted position of the spoiler when the spoiler is parallel with the ground and extend no more than 2 inches past the end of the spoiler. Gurney flaps are allowed but cannot extend above or behind the spill plates. The design is allowed to fill in the horizontal gap between the leading edge of the spoiler and the body with a plate no farther forward than the centerline of the rear axle.
SECTION 5 CAR CLASSES
5.A.4STEAM VEHICLE - /S
This class is for vehicles using steam power as the sole means of propulsion. The vehicle shall be wheel-driven. THE BODY CONFIGURATION IS UNLIMITED. The vehicle and driver shall meet all technical and safety regulations based on the speed of the existing record. The class will be based on vehicle weight less driver. The entrant shall provide a current weight certificate for classification
Class IUnder 1099 lb.Less than 500 kg
Class II1100-2200 lb.500-1000 kg
Class III2201 lb. and overOver 1000 kg
SECTION 7 MOTORCYCLE
SPECIFICATIONS & REQUIREMENTS:
All motorcycle entries, including streamliners and sidecars, shall use tires with an appropriate speed rating. The required speed rating is governed by the record speed in the class entered. Tires rated H CANNOT be used beyond the speed rating. Any run in excess of 200 MPH requires that the contestant return to technical inspection area where the tires shall be examined for apparent deterioration or damage before further runs are permitted.
7.B.19CHASSIS and STEERING:
All motorcycle entries shall use handlebars for steering
control and be wheel-driven. All moving parts of the steering system shall
operate freely without excessive play. It is recommended that all steering system components be visually inspected on a frequent basis.
One-piece or two-piece 350 degrees (zipped together) all leather is required and the zipper must be sewn to the leather. Limited perforations and/or cloth or non-cloth panels are allowed in the armpit and at the back of the knee. No single panel can be larger than a total of 12 square inches each. Fairing (leather or cloth only) on the back of leathers is allowed in Partial Streamlined classes only.
Leather gloves that cover the entire hand and fingers with a minimum 2-inch gauntlet cuff and wrist enclosure are mandatory. Additional safety features such as knuckle, palm and/or finger protection with other engineered materials are acceptable.
