This class is designed for stock chassis vehicles running a true 10.5 DOT approved tire. Vehicles must be registered and insured. Drivers must a valid driver’s licenses from their place of origin.

Street Cruise
There will be a 30-mile supervised cruise on highway and city streets prior to the race portion, limited to vehicles that have passed the tech inspection. An escort will supervise the cruise in accordance with local laws and ordinances. Each competitor and crew will be on their own reconnaissance during the cruise and bear full responsibility of their actions as they would on local streets. Please be safe and follow all traffic laws during the cruise portion.
Cruise is mandatory in the time allotted for completion. Any vehicle unable to complete the required cruise portion under its own power within that allotted time will be disqualified from the racing portion. Any vehicle that drops behind the trailing escort vehicle will be disqualified from the racing portion. No laptops are permitted once the car leaves for the cruise portion of the event.

Support Vehicles
Support vehicles (i.e. tow vehicles, crew vehicles) are permitted but must stay behind the True Street participants and trailing escort vehicle at all times. All support vehicles are on their own reconnaissance and must obey all traffic laws during the cruise.

Cool Down/Return Procedures
After vehicle has completed the cruise portion, they will return to the designated staging lanes for the cool down period. The cool down period will typically last 30 minutes. During this cool down period participants may lower tire pressures, install nitrous bottles, add ice to intercoolers not located in engine compartment. A strict closed hood policy is in effect until vehicle has completed the required three back to back passes. No refueling once vehicle leaves on cruise. Engines must remain off during cool down. External cooling by any means is prohibited. Any engine adjustments or repairs are prohibited. No laptops in vehicle during the cool down period.

Race Format
Racers must report to their vehicles in the staging lanes when called and prepare to make the three back to back passes. All hoods and truck lids/hatch must remain closed until completion of three passes. Additional nitrous bottles or ice for intercooler may not be added between runs, even if located in the interior of vehicle. Tire pressures may be lowered in staging lanes and between rounds. Air may not be added to tires at anytime during the back to back passes. Vehicles are required to make all three passes to complete event. Any vehicle not able to make all three passes will be disqualified. After the racer has completed a pass they must return immediately to the staging lanes for the next pass. Any vehicles trying to gain additional time for cool down between passes by not returning to staging lanes immediately will be disqualified. The only exception to this rule is vehicles that must use a parachute if required by trap speed. The driver is the only person allowed to push vehicle in staging lanes between runs. No laptops allowed in during race portion of event or in staging lanes.

Final Standings
After three back to back runs are completed, each racer’s ETs will be added together and divided by three. The outcome of the three run average will be available at the event awards ceremony. The winner, runner up, and King of True Street will be announced at the event awards ceremony.

Class Safety Requirements
Vehicle and driver must meet NHRA certifications for the time and speed the vehicle is running.

Not that it really will make a difference but you state, "Any engine adjustments or repairs are prohibited. No laptops in vehicle during the cool down period.", does this apply to adjusting electronic boost controllers?

[firebird_1995]

Why would you need to adjust it from the cruise to the race?

I have two settings, normal and race.

More concerned with adjusting the thing after each run, ramping in boost quicker/slower based on prep etc.

[firebird_1995]

Are you ok with me having a stacked chip and to be able to swich tunes with the flip of a switch? What wins TS is the fastest average of 3 runs, and the average of three runs closest to an index time. If you have to make adjustments for track conditions, AFTER your first run, id say you've already lost.

I wouldn't mind you switching, this is a street car class.. why have a race car tune for DD when you can cruise on a softer tune.

More just making some convo here.

[firebird_1995]

I know you are and I appreciate the chatter, but keep in mind that the use of laptops is expressly NOT permitted during the cruise, cool down period, or in between passes. That means I cannot adjust my tune to meet track conditions to aid in traction, or run a street tune vs a race tune. I know what a boost controller is capable of. Very similar to a progressive controller for nitrous users. I honestly don't think we could allow you the luxury of changing boost setting without allowing the nitrous guys to be able to change their settings. Then other users with real time tuning capabilities are going to want to be able to make changes, and rightly so. So no, you may not change your boost controller settings after the initial tech in.

[Ryan Stout]

Say I have a forward facing turbo. Can I run the cruise with the filter on, and pop it off during cool down as long as my hood stays shut?

[firebird_1995]

Afraid not. That would involve using tools.

Consider you are out on the street and someone rolls along side you and is ready to rip. Same situation here. He isn't going to let you pop your filter off lol.

In this for my question, I would just hit the button..switch to kill mode and nail it.

Either way, no matter to me, just asked cause the rules do not specifically indicate anything about EBC or progressives for that matter.
