The 2016 TT season kicked off last week, and we are ready for a great year. The 2016 rules were released on December 3rd, and the TT Car Classification Forms were updated. We also have an updated ST/PT/TT Dyno Certification Form this year, so please use that if you get a new Dyno test. The TT Class Calculator tools that can assist drivers with classing their cars are posted here: TT123 Calculator TTB-F Calculator
All Rules and Forms can be found on the NASA website https://www.nasaproracing.com/rules
For 2017, we are planning on expanding the Time Trial Series to include the new Time Trial 4 (TT4) class. It will be similar to TT3, with a higher Adjusted Wt/HP Ratio, and a few additional restrictions compared to TT3. This class will be the substitute for TTB and many TTC cars as well. Discussions regarding this class are happening on the ST Forums here: http://nasaforums.com/viewtopic.php?f=18&t=131273 Feel free to give your input there.
Also for 2017 (or 2018), we are considering a complete transition of the remaining TT class rules (TTF-TTC) to also be based on Dyno results and the Adjusted Wt/HP Ratio, with additional cost-saving restrictions, as well as a car model specific Modification Factor table to take the place of the base class table. The discussions regarding these classes (TT5/6) are taking place on the ST Forums here: http://nasaforums.com/viewtopic.php?f=18&t=131274 Feel free to give your input there.
Final decisions on whether these new rules and classes will be implemented for 2017 will be made and published by July 2016.
Have a great season!
Greg G.–National TT, PT, ST Director
