alky on a n/a engine?

[monte_383]

Can I make it work on a natuarlly aspirated engine. Actually wanted to use water, but alcohol will work about the same. Got a 12:1 compression 383 and I don't want to have to pay for 110 octane everytime I drive to town. Besides that it is a 50 mile round trip for me just to get 110. Is it possible to adapt a SMC kit to trigger at WOT (with say a microswitch on the throttle) instead of a boost referenced switch? Was wondering if it would work the same as it does on the turbo'd cars. TIA -Chuck

I never really though about that. But it seems likely that it will work, you'll probably have to turn the pump speed way down to keep from drowning the spark in that NA charge. As far as triggering, I'd say mount a switch on the floor beneath the pedal(or even on the back of the pedal) and wire it into the test switch on top of the SMC's control box. Heck, you'll figure out a good setup with some tinkering. Hope it does good for you!

You should be able to wire it to come on at a certain tps voltage

Not to piss on your bon fire, but! W/ a turbo car the engine has to wind up before boost increases and detonation is a risk. Wit a NA car, high compression and ping can occure anywhere. . I am not say that it wouldn't work, but you would have to run the alky all the time, not just at WOT. Now the problem lies in trying to make a system that is multistaged so that it won't spray the same at idle as it does at WOT!

It might work if it is activated by a vacuum sensitive switch. It would probably need to have a pump that increases speed with rpm. The KB blown cars have a problem similar to N/A ones since full boost is there by 2,000 rpm to redline. I have ended up using dual nozzles with one being boost activated and the other being boost and rpm activated. Otherwise it will bog the engine at lower rpm's or not supply enough spray at higher rpm's. The spray required is determined by the volume of air the engine is moving which is constantly changing throughout the rpm range. The ideal controller box would increase pump speed based on engine rpm.
