Time Trial basics

The purpose of this page is to ease the transition from HPDE4 to Time Trial (TT).  Obtaining the driving skills may be difficult for some, but the process to get into Time Trial should NOT be!

 

Time Trial Licensing Process:

Option 1 – Traditional Method

    • Drivers work their way through the NASA “ladder system” w/ sign-off for each level by an Instructor or Group Leader
    • When a driver has experience in HPDE4 or shows evidence that their overall performance/skills are appropriate, one final sign-off is simply requested to move into “Time Trial” (aka – “HPDE5”)

Option 2 – Similar Experience with alternative Organization

    • Advanced/Expert level drivers who already compete in similar style events and show evidence of being competitive for their series/class may apply directly for a Time Trial License
    • Drivers who choose this path and may not be familiar with NASA protocols must show initiative by already having their car properly classed via the Time Trial Rules as well as ensuring their car number does not cause a duplicate number issue for T&S and track officials.

 

Key Points & Resources for Time Trial:

  • Time Trial Rules – NOTE:  TT classification info is NOT in the Time Trial Rules but instead are detailed out in the Super Touring (ST) rules (since ST & TT are the same):
  • Classing Calculator
  • Dyno Certification Form – NOTE:  The most common questions are all answered on page one of this form under “Dyno Testing Procedures:“.  Please make sure to READ all 14 of the bullet items to ensure you (& the dyno operator) do it properly!
  • Annual Tech – A NASA Logbook will be issued but it will be stamped “TT Only”.  Additionally, a TT only car will have the annual tech sticker affixed to the lowest part of the driver side windshield (as opposed to the roof or highest part of the driver side windshield for race cars).  The Annual Tech form is the same one used for “wheel to wheel” Race cars.  Despite Time Trial cars only requiring the min HPDE requirements, drivers should expect to be held to a higher standard.  Examples:
    • Tow hooks
    • Fire extinguisher/system
    • Harnesses that are in date (or barely expired)
    • Safety gear exceeding typical HPDE participants
