How about a nitrogen cylinder mounted in the trunk?  I know this posses
some plumbing problems, however a nitrogen cylinder with a regulator set at
around 100psi and a nitrous oxide injection nozzle and solenoid would be a
simple yet effective setup.  The nitrogen cylinder would be easily
recharged at a welding supply shop and since it is an inert gas, should
pose no fire hazard.  

Does anyone think this is crazy?

The one problem I do see is how to meter the water.
