About

Super Gas entries, which run on a 9.90 index, are primarily full-bodied cars and street roadsters. No dragsters or altereds are permitted. Rules regarding engine and chassis modifications are extremely liberal, though the use of exotic fuels is prohibited. The minimum weight is 2,100 pounds except for four-cylinder-powered cars, which may have a minimum weight of 1,200 pounds. As in Super Comp, competitors use electronic timers and throttle stops to run as close to the class standard without going under. Also as in Super Comp, races are staged using a four-tenths Pro start.
