Turbocharger size will be verified by measuring the housing bore at the leading edge of the impeller wheel. The maximum diameter of the housing bore at the leading edge of the wheel may not exceed 2mm more than the maximum allowable turbocharger size permitted. All turbochargers must meet SFI Spec. 61.1. Nitrous oxide injection with turbocharged engines prohibited. Maximum permitted turbo boost is 36 psi. Boost controller manufactured by Hyperaktive Performance Solutions, part No. PMBL is mandatory. No other boost controller or form of boost control permitted.

The Junior Dragster regulations were upgraded earlier this year, the 0.4 immediate disqualification regulation still remains, the rule regarding potential disqualification has been clarified with the regulation details below.

During Qualifying any Racer running under the class minimum index by less than 0.2 (.001-.199) seconds will automatically go to the bottom of the qualifying ladder, the run will no longer be disallowed, any run .02 and below index will activate the standard under index disqualification rules of a warning on the first instance and exclusion from the event on a second infraction.

Drivers running under their class minimum index by less than 0.2 (.001-.199) seconds during eliminations will not be automatically disqualified, the first or worst regulation will also not apply for Racers going under index within these parameters (.001-.199. The normal break out rules will still be applied in dual break out elimination rounds.

Any Driver running quicker than 0.4 under their minimum class index or exceeding 85 mph at any time during an event will be immediately excluded from that event. If a driver has no previous experience in Junior Dragster Racing, he or she must successfully demonstrate driving proficiency prior to competition.

The current SPRC Rulebook GSR 7:3 states numbers must be a minimum 76mm (3-inches high) and 38 mm (3/4-inches) wide. The correct dimension should read 76mm (3-inches) high and 19mm (3/4-inch) wide.
