In NASA Time Trial competition, anything goes, from prototype racecars and converted production cars to economy cars. Weight-to-horsepower ratios make for fair classes and lots of creative freedom to build the car you want. NASA Time Trial provides a venue for spirited on-track competition with a high degree of safety and convenience. NASA Time Trial allows qualified individuals to compete in a “best lap time” format in a prepared car in advanced level open-passing sessions, and bridges the gap between NASA HPDE 4 and wheel-to-wheel racing.
– New to TT or NASA?: In order to compete in TT you need to have significant NASA defined Advanced HPDE experience. If you are new to NASA we reserve the right to require an evaluation period and may ask you to sign up for HPDE before allowing you to run TT. Some other organizations’ “Time Trial” groups differ in definition and practice, and we want to make sure any new to NASA drivers have proper understanding of our rules and procedures so you and all other drivers can compete in a safe environment. Checkout rides by the TT staff or senior instructors are available for HPDE 3 & 4 drivers to be evaluated for TT. If you are considering TT please fill out the license application and email email@example.com.
Classes: NASA Time Trial runs 7 Classes, TT1-6 and TTU. These follow the same rules and classifications as the Super Touring Race classes. For specific information about classing and what is legal/not legal in each class consult the Super Touring/Super Unlimited section of the NASA rules page here.
