In Reply to: Chris, you left out water injection. ntxt posted by PittMan on Friday, May 26, 2006 at 12:49PM :
Not vapor injection, which is just a vacuum leak w/ bubbles. But a high pressure water injection with nozzles that spray water into he intake air path. Ever notice how your car runs better in the rain? Same thing. The water will cool the combustion chamber, allowing todays automatic ECPs to advance the timing. But if it screws up, you could hydrauluic an engine. If it don't screw up, it can rust carbs and injection systems, lije driving in the rain. You need a system with a plastic fuel pump for the water, lots of fail-safes, (oil pressure cutoff, electrical cuttoff,anti syphon valve) and a controll system to vary the water. It should use something like 15% as much water as fuel for optimum benefit. So, 5% could help.
Systems today are sold mostly for extreme boost on turbo'd engines, cost $400. I sure put on hundreds of them in the early 80's. Edlebrock made an electronically controlled system about then too. I might cook up my own this summer, if I can find the right propane regulator to modify to controll flow...
My guess is that the O.E. mfgs don't think the consumer wants to bother with another tank to fill. Or the maintenance, minerals do plug them up, so distilled water is preferred.
