Time Attack Format and Rules

Rules

A vehicles class is determined by its weight (race ready, with driver) DIVIDED by its peak WHP (W/H=Class), and tire UTQG

Class A, B, C, D, and R must be factory production road going vehicles available to the public with attached VIN.

  • TA-A: 15.00 and up, 100 UTQG and above
  • TA-B: 14.99 to 10.00, 100 UTQG and above
  • TA-C: 09.99 to 5.00, 100 UTQG and above
  • TA-D: 04.99 to 0.01, 100 UTQG and above
  • TA-R (Race): No PTW limit, no tire limitations
  • TA-U (Unlimited): No PTW Limit, no tire limitations (see competitor eligibility rules below for TA-R to TA-U comparison)

Classing eligibility is based upon a vehicles declared weight, its HP and inspection:

  • Dyno/HP
  • Tire UTQG
  • Weight

Dyno eligibility:

  • A dyno sheet obtained from UMS Tuning
    • This dyno sheet is the only “officially” recognized dyno for the SWSF / UMS Tuning Time Attack Event
    • A yearly dyno is required to be considered for event points (or carry over to UMS Time Attack)
    • For this event, a Dyno Day will occur in close proximity to the event to allow competitors to get classed 
      • The dyno fee is $60 for FWD, $90 for RWD which includes 3 pulls
        • Best pull of 3 is used for classing
    • An unofficial dyno obtained from a 3rd party dyno/tuning shop / out of state dyno sheet
        • This dyno sheet must be approved by UMS Tuning or the Time Attack Director
          • UMS Tuning or the Time Attack Director will assess the validity of the dyno sheet (equipment used, vehicle modifications and location of test into consideration), and authorize and assign a proper classing for vehicle
        • Upon approval, the participant must pay a onetime entry fee of $60 for FWD or $90 for RWD

The fee is used to provide prizes for competitors

    1. Purpose built non-production vehicles (production race vehicle) may participate in class U
    2. Production road going vehicles with a VIN that utilize non DOT tires (racing slicks) may participate in class R
  7. Vehicles must be classed and recognized as a Time Attack vehicle for points eligibility
    1. Dyno and weight is required (see Rules above)
  1. Vehicles may add ballast, but are limited to a maximum amount of 250 lbs

    3. Weighing

 

Appendix and Definition of Terms

Actual vehicle weight:  The actual weight of the vehicle (including driver) immediately after running the Time Attack as measured on event scales.  In most cases the weight can be done prior to the Time Attack, but in the event of a questionable protest, another competitor can request that the vehicle be weighed immediately after the Time Attack laps.

Ballast:  “Ballast” is a safe means of adding weight to a vehicle.  The most popular methods is adding lead bars or readily available home gym weights to the floor of a vehicle and secured with large bolts and washers.  If ballast is added to a vehicle, it must be present in the vehicle at the time of the tech inspection in which the tech inspector can sign off on the mounting technique for the ballast.

DOT Legal Tire:  ANY tire with a DOT rating and legal for use on a public highway.

 “Power to Weight” method:

  • Modified vehicles will use the “actual vehicle weight” and HP as measured at the wheels at the UMS Tuning dyno. Vehicles that are in a questionable class and do not have a readily available dyno chart to prove HP output will be classed at the discretion of the Time Attack Director or UMS Tuning officials.  All competitors that feel they may have borderline vehicles are *highly* encouraged to get a vehicle dyno to settle any potential protests and avoid any subjective classing.

Production Race Vehicle:  Any production vehicle that was built for the sole purpose of racing and never intended for public roads by the manufacturer.  Examples of these types of vehicles would be a Formula Ford, Formula Mazda, DSR, Porsche Cup etc.  NOTE:  The Time Attack Director may make some exclusions such as the Competition Viper – no VIN, old Bondurant Mustangs – no VIN, etc.)

Racing Slicks:  Any tire without a DOT rating.
