Tire changing is prohibited during or after the road tour.

    When called to the staging lanes, all Street Challenge competitors must report to their cars and prepare to make three back-to-back 1/8 mile passes. All hoods and deck lids must remain secured, as they must remain closed until completion of all three passes. Vehicles with air-to-water intercoolers may not add ice to intercooler tank between back-to-back passes, even if intercooler tank is located in interior of vehicle.

    After all three 1/8 mile passes are completed, each racer’s ET will be added and the average of these three passes will be computed. The outcome of the 3-run average will be posted, and the awards presentation will be held after all racing is completed. On a qualifying run, if a contestant properly starts, stages and receives the starter’s signal but breaks to the point the run is not completed, a time of 28 seconds is issued and it is considered a valid qualifying run.

    are not permitted around participating vehicles, in the staging lanes, or in the burnout area, between rounds of competition.

    Tire pressure may be checked in the staging lanes, or between rounds, and may be lowered. Air may not be added to tires any time during the back- to-back passes. Vehicles are required to make three full passes in order to be included in the final average ET tally. All vehicles must run three passes in the same order as the first pass, any attempt to gain additional cool down time between rounds will result in disqualification. The only possible exception to this rule is the use of a parachute, if required by vehicle speed. One crew member can be placed in the staging lanes to aid in the re-packing of a parachute, however, chute must be re-packed in a manner so as not to be disruptive to competition rounds. There will be a separate staging lane designated for any vehicle needing to re-pack parachutes. Any vehicle unable to start under it’s own power will be disqualified. Once all rounds have been completed, prize money and awards will be given based on the final average of all three 1/8 mile passes. During, and in between, the back-to-back passes, no changes may be made to vehicle other than lowering air pressure in tires. Fresh nitrous bottles, fuel, and ice may not be installed/replenished. Vehicles with air- to-water inter-coolers may not add ice to inter-cooler tank between back-to-back passes, even if inter-cooler tank is located in interior of vehicle.
