Time Trial

When HPDE4 drivers are ready for competition they can choose either wheel to wheel racing or “Time Trial” (or both!). Time Trial is ran similar to an HPDE group where multiple cars are on track at the same time in an open passing environment but with a few distinct differences in that vehicles are assigned a grid spot based on their lap time (fastest in pole position with the slowest in the back), all cars are properly classed and lap times are provided for each session.  The fastest lap from any session that day (assuming you don’t spin or go off track) is your official competition time for the event.
Unlike most other organizations that severely limit competitors or classing modifications, NASA’s Time Trial (TT) series allows competitors to choose how they build their car and what modifications to perform. Each modification is assessed a set number of points and the more mods the higher the class. It’s that simple!
NASA Arizona’s Time Trial competition season lasts from Jan-Dec each year locally as well as the opportunity to compete Nationally at the NASA National Championships each year where they can go up against the best of the best in the country across 15 NASA regions!  NASA TT competitors are eligible for the coveted NASA Arizona Champion jacket as well as many contingency awards such as free tires, brake pads, gift certs, discounts and more!
In total, there are nine Time Trial classes, evenly separated by the vehicles power to weight ratio and/or the points associated with each vehicle modification .  Awards are provided to our top 3 finishers at each of the regional events.  To compete in NASA TT, a driver must obtain a NASA National TT License, which requires the driver to be an advanced level driver or racer before they may apply for a Time Trial License.


What is the process to get my Time Trial License?

  1. Demonstrate proficiency in the NASA HPDE program (or equivalent) and have a fair amount of experience in HPDE4 (i.e. Advanced group with open passing)
  2. Fully read and understand all Time Trial rules and properly class your car (https://drivenasa.com/rules)
  3. Ensure you have selected a unique car number @ http://forums.nasaaz.com/showthread.php?t=3171
  4. Obtain a recommendation from the HPDE4 Group Leader to apply for a NASA Time Trial License (https://drivenasa.com/http:/www.drivenasa.com/images/rules-forms/Time-Trial-License.pdf)
  5. Submit your application to the local NASA AZ office.  NOTE:  Applications will be approved by the local office pending steps 1-4 were properly followed

If you are an HPDE4 driver but have not received sign off from the Group Leader (i.e.  “Step 3”) but you feel you are ready for Time Trial, you may be allowed to sign up for HPDE4 but be allowed to run in the Time Trial group as your “evaluation weekend”.  At the end of the weekend, the Time Trial Co-Director(s) will either accept your application or require more seat time in HPDE4 before applying again.




RACE Group

Want to race “wheel to wheel”?  Here’s what you need to do!

  1. Current “NASA membership” (https://drivenasa.com/users/sign_up)
  2. Read and fully understand all NASA CCRs (https://drivenasa.com/rules/ccr.pdf)
  3. Driving experience in NASA’s HPDE1-4 groups or equivalent (email Tage@nasaaz.com to confirm what is considered “equivalent”)
  4. Completion of a NASA “Comp School” (or equivalent race experience from another org – email Tage@nasaaz.com to confirm)
  5. Medical clearance from your Doctor that you are healthy enough for the rigors of a racing environment (https://drivenasa.com/forms/form_medical.pdf)
  6. Apply for a NASA Provisional / Competition License (https://drivenasa.com/forms/form_provisional_license.pdf)
  7. Application approval by the local region (NOTE:  Approval will be granted by pending steps 1-6 are properly fulfilled)
  8. Select your race series and class (Series and class rules found @ https://drivenasa.com/rules)
  9. Annual race tech inspection (details can be found @ https://nasaaz.com/tech/tech-inspection/)
  10. Register for an event and go race!  (https://drivenasa.com/events)

UMS Time Attack Rules

Time Attack (TA)

The TA series was formed locally and has no national support from NASA, and no national rule book or guidelines. NASA AZ and UMS Tuning have partnered to create this series  All rules, format, driver classing and administration were formed by NASA AZ members.  The TA series mimics the time attack events like Global Time Attack (GTA).  TA drivers pay $20-25 in additional to their regular registration fees to enter the competition.

TA Drivers are given 1 warm up lap, 2 hot laps, and 1 cool down lap.  The objective is to the the one fastest hot lap in your respective group.  Drivers are grouped into heat and released in intervals to give equal opportunity for quick laps.

The classing for TA is simple:  power to weight.  There are three main classes, each with a range of power to weight limits.  The purpose of this is to allow new entrants easily and not have the worry of classing cars using a complex set of rules.  The TA series is more “loose”, and meant to be fun, although some take it rather seriously!  You can see the full set of rules below.

TA drivers can also win fun prizes and bragging rights!  This series is open to drivers in HPDE3, HPDE4, and Time Trial.
