Haven't seen one of these crop sprayers. Is it like one of those bilge pumps you can drive with an electric drill? Hmmm....

I'm currently using 2 windsheild washer pumps in series(30psi), feeding 2 nozzles(~350cc/min total) from spray bottles. The nozzles have been cut off and had small brass hose barbs screwed into them for water supply. Ever see how well hand pumped spray bottles can atomize? It seems to work OK. I don't have a dyno.
I inject into the atmospheric side of the compressor(I know it's a no-no). You could boost reference it by using boost to pressurize the resevoir behind the pumps.

Pressurized resevoir from some source of pressure? How bout something like one of those air bags they use in 4x4's for rock climbing, or for pre-loading the suspension in drag racing, lo-riders, etc? Then let the weight of the car put pressure on it? Super simple. "Why's the car getting lower as we drive?"

Well, if you're fishing.....

I remember seeing some cheezy little WI set-up somewhere that used the air pressure in your spare tire to pressurize a water resevoir.


Hmmm.... If you had a pressure tank, with like say 2000psi of nitrogen/CO2/etc. in it, and then had a dead head regulator on it to drop it to 200psi, then fed that to a 200psi-safe tank with a bladder full of liquid in it, you'd get a good, long lasting supply of 200psi liquid from the bladder. To fill liquid, just turn the regulator to 0psi and fill 'er up. Turn reg to 200psi again to re-pressurize. Use a solenoid to control flow. Refill tank every once in a while.

At this point tho, why not just fit a Nitrous system?
