injection plus carb?

would it be a feasible project to have a carb manifold work with an injection system?......i.e my idea/conecpt would be have a injection system running lean gas, while still have a carb running lean alcohol, so there would be no throttle body or anything, air would still be pulled in through the carb and mixed with a small bit of alcohol, then the injectors mix in a bit of gasoline to create a normal ratio of air/fuel but obviously a little potent......plus i think thats an awesome novelty


now if there are problems i would havve to work out (besides for proper ratios as i can see this being a big problem already) please explain them because i would really like to attept this project either now or sometime in the near future

good luck

I don't think it would be possible, but if you are ever able to pull it off we would all like to see.

You might be able to modify a TBI unit to work in this manner, it would mean installing a third injector on the TBI. You would need 2 complete fuel systems that would then need to be metered together by a computer running some very sophisticated software. Since Alcohol would be used up faster than the gas that would be another issue. Most pump gas already has alcohol in it, so getting a proper mix might be a bit of a science experiment. You might want to consider using a water injection system that squirts alcohol instead of water. This way you would run gas at idle and only inject the alcohol when the engine is under demand for power.

Just a though

Mark

I'd rather have a vaporized gasoline system, somehow 100 miles to the gallon sounds more exciting, Wait... is that the SS at my door?

My big question is why? If your going to go through the trouble of setting up a fuel injection system for the gasoline why not add injectors for alcohol too and have the ecu control the modulation between the two and ditch the cab all together?

I agree with buckethead. If you really want to do this, you should just run more injectors so that fuel can be properly controlled. Running a carb with efi does not make sense.
