The mission of this division is to re-create the gas classes from the end of the Gas Class era. Most all street legal has been removed as these are full on race cars. We almost called this the outlaw gas class. As with any sanctioning body, the safety of the fans, participants and facilities is paramount. All safety regulations will be current NHRA safety regulations. NHRA safety rules and track rules supersede these guidelines where applicable in the name of safety. All other guidelines will be designed to keep the experience as genuine as possible while not being too difficult for the sanctioning body to enforce. Gasser Madness, the writer and administrator of said guidelines herein are not instructing an owner on how to construct participating vehicles, only classifying how participant vehicles are presented.
Competition Gas division is for race cars that can be more modern in appearance with a low stance for stability and aerodynamics afforded by modern slick technology and track prep. This class allows for narrowed rear ends and wheels tucked under the fenders/quarter panels. These guidelines could be interpreted to incorporate any modern race car but will be limited to gasser style vehicles. Bodies, engines, drive trains, chassis, etc. may not be altered, modified, or relocated, except as noted in class requirements. Push starts are not allowed. Return to the pit area by use of a push car is permitted. Unless track conditions prohibit it, all competition in Competition Gas will be ¼ mile handicap racing. Sportsman tree will be used.

Removable weight must be securely mounted to the frame, frame structure, by at least two 1/2-inch minimum diameter steel bolts; however, the use of railroad track, cylinder heads, or other bulky items not permitted. Recommended forms of ballast are: heavier gauge steel floors,-i.e., 16 or 18 gauge, etc. frame reinforcing cross members, or the addition of safety equipment such as roll bars, flywheel covers, etc.

INSPECTION: Each car, regardless of class, must complete and satisfactorily pass the inspection of the technical committee before being allowed to make a time trial run or participate in any Gasser Madness Gasser Magazine sanctioned event. All nuts, bolts and component parts on each car’s suspension system, chassis and running gear must be secured with lock nuts, lock washers or cotter keys, and must have at least one full thread showing through nut. All safety requirements are current NHRA safety regulations.
CREDENTIALS: Each driver of a vehicle entered in any NHRA sanctioned event must have a valid driver’s license subject to inspection by officials at time of classification, or at any other time deemed necessary by the technical committee. All drivers in all classes where required must have a valid Competition License.
STANDARD ELIMINATION PROCEDURE:
The “round-robin” system of elimination is recommended. With this tournament-style of competition, entire classes are called to the line in logical order starting with Supercharged class first. One complete round of eliminations is run within each class. Any single, or un-paired, contestants are required to make a solo run. Upon completion of the final round, the second round is immediately started. This system is continued until all class winners are finally determined. The ··round-robin” runoffs also permit complete control of competitors; each time a complete class is called to the staging area, cars not showing for competition can be noted and automatically disqualified from further competition, thus assuring that the eventual winner in each class has made a fair share of runs.
