A member has inquired if a super charger and nitrous injection are compatible or mutually exclusive for air charge cooling purposes.
I have both with my centrifugal S/C. The nitrous (50 shot) is injected after the air is compressed but before the charge reaches the throttle body. I do not utilize an intercooler.
On an Eaton or other top of the motor set up (roots), the compressed air is not accessible so the cooling effect of the nitrous is greatly reduced. An internal intercooler is located in the upper intake manifold to help cool the compressed air charge.
So, my understanding is that adding nitrous to a roots type supercharger for additional intake cooling is not effective.
Adding nitrous as a power adder to a supercharged motor is compatible but several factors must be considered: total horsepower doesn't exceed engine design limits, combustion chamber temps, fuel delivery system, tune (timing) exhaust limitations.
Thought's.
