I know some people in the smaller engine world ( carb'd 4 and Inline 6cyl ) put 1 or 2 fogger nozzles on a log intake and use it just as a standard N20 system, because in most cases, there is no plate to fit the carb base. my thinking is 2 nozzles could be drilled and tapped for right into where the carb goes ( in the common plenum, before it goes into the individual runners ), they would have to be drilled at an angle, but 1 in each side of the plenum ( assuming a dual plain intake ) would work just as good as a plate system or the top shot system. it could go togther fairly cheaply, 2 fogger nozzles, a couple solonoids, lines, preassure gauge and a bottle.
