where are you going to carry the water or CO2 bottle ?
still working on that part. but i was thinking about using a small paintball tank such as a 4 oz which is 5" tall and 2" diameter (probably would need multiple)

or a 9 oz which is 10.5" tall and 2-1/8" diameter

obviously the system is not going to be large enough for a constant blast of CO2 but might be able to be during situations where the engine is hotter than normal such as heavy traffic or when racing
