All vehicles participating in Time Trial will automatically be entered into the TTT competition. This new innovative class will allow all drivers to compete against each other with the goal of being the most consistent between their fastest lap of the day and their next three fastest laps, using the fastest two laps of each session as the source for the data points. A driver is qualified for the TTT podium as soon as there are at least four (4) lap time data points (requires a minimum of two completed laps from two different sessions). However, the driver can continue to improve their TTT position by running additional sessions. All TT sessions that are not disqualified (DQ’d) will count, including practice sessions that do not count toward regular TTU/TT1-6/TTEV competition. The results will be tabulated by NASA’s proprietary program after each session and posted along with usual session results. The TTT results will show the competitor’s fastest lap time, and then the 2nd fastest, 3rd fastest, and 4th fastest lap times along with the Delta” (Δ) for each. The winner will be the competitor with the smallest summation of those three Delta’s. READ MORE Everything You Wanted to Know About NASA’s Time Trial Program Compete for the best lap time in your street or race car! In NASA Time Trial competition, anything goes, from prototype racecars and converted production cars to the current crop of electric 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. Series Description NASA Time Trial is an automobile road course competition series focused on time trial-style competition, and shall function as an advertising and marketing tool for the series sponsors, the independent sponsors of each team, as well as the official sanctioning body of the series. Eligible Makes and Models Virtually anything from Acura to Volkswagen in race or street trim is eligible to compete in NASA Time Trial. There are the usual classes for internal-combustion-engine cars, and now EVs also have a Time Trial class in NASA. Donor Prices and Availability Because you can run anything in NASA Time Trial, donor prices to build a new Time Trial car range from several hundred dollars to several thousand. Daily driven street cars also are eligible to compete in Time Trial. From shop floor to showroom floor, all cars are welcome. Engine Specs There are no engine specs, per se, but according to the rules, the Adjusted Weight/Power Ratio for each vehicle will be calculated based on a simple competition weight to average chassis dynamometer (Dyno) horsepower ratio (Wt/Avg HP), followed by the adjustment of the resulting ratio by adding to, or subtracting from it, based on the list of Modification Factors.” Competition Weight is defined as the minimum weight of the vehicle, with driver, any time that it competes in a qualifying session or race. Average horsepower calculation (Avg HP) is defined in Section 7.2.” Weight All vehicle weights will be measured to the tenth of a pound (xxxx.x), and then rounded off to the nearest pound for all calculations. Any weight ending in .5” (xxxx.5x) NASA Super Touring (ST1-4 & SU) Rules 2020 v14.1 Page 13 of 28 will be rounded up or down to the benefit of the competitor. All horsepower measurements will be rounded off to the nearest whole number, and any number ending in .50” (xx.50x) or less will be rounded down. Any Adjusted Weight/Power Ratio” calculation ending in .995” (xx.995) or greater will be rounded up to the benefit of the competitor. TT1 = Adjusted Wt/HP Ratio” equal to, or greater than, 6.00:1 TT2 = Adjusted Wt/HP Ratio” equal to, or greater than, 8.00:1 TT3 = Adjusted Wt/HP Ratio” equal to, or greater than, 10.00:1 TT4 = Adjusted Wt/HP Ratio” equal to, or greater than, 12.00:1 TT5 = Adjusted Wt/HP Ratio” equal to, or greater than, 14.50:1 TT6 = Adjusted Wt/HP Ratio” equal to, or greater than, 19.00:1 Fuel Required Nitrous oxide use is prohibited. Pre-existing tanks must be removed. Methanol/alcohol-water injection is permitted provided that the mixture does not exceed 50% alcohol by volume. Methanol is not permitted as a fuel. (See CCR 15.19 and 18.3) Average Cost to Build Car Because the cars in TT are so varied and because some of them are street driven, there really is no average cost. Figure $10,000 to $15,000 for a race-prepped TT5 or TT6 car. From there, prices rise with speed and horsepower. Average Cost to Buy Built Car You can buy anything from a used first-generation Spec Miata for $5,000 to a $250,000 prototype. Your budget will determine how fast and powerful a car you get. Typical Modifications That’s the beauty of Time Trial. You choose which modifications work best on the car you have chosen to build. The rules allow for freedom and creativity. Cost Analysis Average cost to run a weekend — $500 to $1,000. Consumables Prices Tires, size, brand and prices Because wheels vary widely with car choice, figure $192 for 205-50-15 Toyo Proxes RRs to $315 for a 275-35-18 Proxes RR. Brakes, brands and prices $150 to $250 depending on the car you choose. Available Contingencies Check the NASA Contingencies page for the latest programs. Factory Participation NISMO, Mazda Motorsports. Benefits Build whatever car you want Variety of competing cars Lots of creative freedom within the rules Lots of tire choices available Challenges Competitive cars can get pricey Electric cars are coming on strong! Rulebook Highlights TTEV (Electric Vehicle) Classing TTEV (Electric Vehicle) is an Open class for Tesla Model 3, Tesla Model S, Porsche Taycan, Ford Mustang Mach-E, and other performance electric motor vehicle models as added in the future. HPDE technical safety inspection rules shall apply. No modifications are permitted to the factory motor, software, EV related safety features, or batteries (other than replacement of the 12-volt lead-acid accessory battery), except that aftermarket hardware and software solutions to disable traction and stability control and to maximize cooling systems are permitted, provided they do not increase power output or alter the ABS system. All vehicles must use either tires with a UTQG treadwear rating of 180 or greater or the Toyo R888R or Toyo RA-1, with maximum size 305mm. Note that future additional classing rules and/or Modification Factors may be added. (The Tesla Model S Plaid may compete in the TTU class using the same rules as above, except that tires and ABS are unlimited.) TT Classification Forms In order to accrue points or compete, each year/season, all NASA TT competitors (except TTU competitors) must submit a current year, completed NASA ST/TT Car Classification Form (and certified Dyno report) to the Regional TT Director prior to having lap times count toward competition. Once a form has been submitted during a season, if there are no modifications to the vehicle that would change the form, a new form does not need to be submitted at subsequent competitions in the same region. A new ST/TT Car Classification Form copy (and certified Dyno report) must be submitted when a competitor competes in a different region or at a Championship event, or if changes have occurred to...
