Want to compete in Time Trial? Read this.

So, you think you want to drive in Time Trial? Time Trial is a great choice for drivers who are ready to test their competitive driving skills. If you have never driven in Time Trial with NASA SoCal, read on to find out how to get started.


Typically, we require that you successfully complete HPDE 4 at a NASA SoCal event. This means that an instructor has approved you to move into Time Trial. If you are new to NASA and have appropriate experience from other major racing organizations, we may allow you to skip this step and go directly into Time Trial competition. Additional licensing information is here.

To be considered for immediate entry into Time Trial, please e-mail a brief resume of your competition experience to John Magnuson, [email protected]. We will get back to you quickly with a decision.

If you think you meet the eligibility requirements, you can apply for your NASA Time Trial License HERE.


Time Trial rules: https://members.drivenasa.com/rules/time_trial_rules.pdf

You MUST properly classify your car before you compete. This involves taking your car to a Dynojet dyno for a power test (on a Dynojet dyno) and weighing your car.

Car classification rules, forms and procedures can be found in the Super Touring series rules:

TT1 thru TT4https://members.drivenasa.com/rules/super_touring_1-4_unlimited_rules.pdf

TT5 and TT6https://members.drivenasa.com/rules/super_touring_5_6_rules.pdf

Make sure your dyno operator also completes the certification form here:


Once you know your car’s maximum wheel horsepower and minimum competition weight (with driver), you should start playing around with the online classification tool to figure out where you’ll be competing: https://form.jotform.com/drivenasa/st-tt-car-classification-form

If you don’t have time to complete the full classification process before your first Time Trial event, we can put you in the unlimited class (TTU); or, you can run in HPDE4 which is very similar to TT, but without the competition aspect.

Make sure you come to the first morning meeting. You may need to stay past the end of the meeting to discuss our operational procedures in more detail.

Hope this helps!
