NOS

[NaN]

Hi, I have never seen N2O being used circuit racing. But I see the fun factor.

I'd love to have some details about nitrous oxide injection. What I've found is:
N2O is injected to increase the oxygen saturation allowing to burn more fuel. So I think it should scale the engine output torque.
Wikipedia says the power increase is up to 1.5 times engine power. But it surely depends on the thermal/mechanical limits of the engine.

About the car parameters:
What is the usual N2O bottle/tank size 1-10kg? If the tank mass is about 10kg. Its mass contribution/position can be neglected.
Liquid N2O density is constant(should be somewhere about the density of liquid nitrogen 0.8g/ml). I think we don't need it in the parameters file.
What are realistic nos-boost values(1-1.5 or more)? Should the user be able to regulate the boost amount in game?
What does the consumption depend on? Should it be proportional(boost-value) to fuel consumption?

I am not sure what you mean with "NOS sound and flames coming out of the exhaust pipe".
You can observe a so called Back-fire on racing cars caused by incomplete combustion during deceleration/gear shift(suddenly closed throttle). The unburnt fuel ignites on the hot exhaust pipe. I'd love to see this effect in VDrift.
