I'm pretty sure they don't use nitrous because I read the cars specs and they didn't mention nitrous.... Here are some of the rules from the class they run.....
"PRO RWD
4 cylinder/2 rotor: 2,000 pounds 1 or 2 power adders
Maximum displacement 2.8 liter (170.75 ci)
3 rotor: (no change): 2,200 pounds 1 or 2 power adders
6 cylinder
3.5 liter (213.50 ci) max: 2,350 pounds 1 power adder
3.5 liter (213.50 ci) max: 2,450 pounds 2 power adders
Max turbo on 6 cylinder = 91.5 mm single, 72 mm twins, measured as follows:
Single Turbocharger - Single turbochargers are permitted with the following requirements: 1) Turbocharger must be of conventional impeller and housing design and type. 2) Turbocharger is limited to a maximum size of 3.602" (91.49mm) - inducer wheel diameter at the point where the leading edge of the compressor wheel meets the inlet housing. 3) Inlet housing is permitted a maximum inlet diameter of 3.673" (93.29mm) where the leading edge of the compressor wheel meets the housing. 4) All air entering the turbocharger must pass through the turbocharger inlet. Injection of any liquid, gas or any other substance into the inlet or exhaust housing is prohibited. Turbocharger compressor wheel must be constructed of cast or billet aluminum. Exotic material wheels prohibited.
Twin Turbochargers - Dual (2) turbochargers are permitted with the following requirements: 1) Each Turbocharger must be of conventional impeller and housing design and type. 2) Each Turbocharger is limited to a maximum size of 2.834" (71.98mm) - inducer wheel diameter at the point where the leading edge of the compressor wheel meets the inlet housing. 3) Inlet housing of each turbocharger is permitted a maximum inlet diameter of 2.905" (73.78mm) where the leading edge of the compressor wheel meets the housing. 4) All air entering the turbocharger(s) must pass through the turbocharger inlet. Injection of any liquid, gas or any other substance into the inlet or exhaust housing is prohibited. Each turbocharger compressor wheel must be constructed of cast or billet aluminum. Exotic material wheels prohibited."
As you can see if they used 2 power adders (turbo + nitrous) they would have to weigh 2450lbs, but with a single power adder they can weigh 2350lbs.... Even if they are using 2 power adders it's still very impressive!!!
