What happens when the nitrous temperature is too cold?
In reverse of the problems caused by supercritical nitrous oxide temps, if the temperature of your supply nitrous it too cold, you’ll have plenty of liquid, but you won’t have enough vapor pressure to forcefully push the liquid into your combustion chamber. The result of this would be a very underpowered flight, due to an under pressurized combustion chamber. You should not fire a hybrid motor if your supply tank pressure is below 500psi.
