I have an MF2 injector controller, FMAX intake with two additional injector bosses welded in, and an MSD inline pump I'm not using. I'm not using the FMAX fuel augmentation 'cause I've got the DSM 450cc injector hack going on. Could I take that inline pump, plumb it into my windshield washer reservoir, fill the reservoir with a water/alcohol mix and use the MF2 to water inject my intake under boost? Is an alcohol/ water mixture going to **** up those injectors in no time flat?

 

I'm not sure about it messing up the injectors...I'd say that just plain alcohol would be better, but then there's the issue of blowing up your car since it's in the reservoir...I'm thinking of an alcohol injection set-up using a seperate washer fluid pump...do you think it would do anything to inject it prior to the TB, just using a washer jet?...or would it not disperse enough/not make it to the combustion chamber?

 

If you got high boost a washer pump might not develop enough pressure to overcome the boost. The washer jet also probably wont atomize the fuel enough. I've heard garden automatic misting nozzles work well.

 

How do you plan to regulate the water/alcohol supply ?

It sounds like cake, but it still is scientifically based.

 

Well the MF2 injector controller is normally used to inject additional gasoline into the intake (pre throttle plate) under boost, it comes with a GM 3 bar MAP sensor which I also have. So when I go into boost it would inject water/alcohol instead of gasoline according to the RPM versus MAP sensor settings that I can adjust in the MF2. In other words I can tell it how long I want the injectors open for a certain MAP sensor voltage and RPM. Oh yeah, I forgot about the pump, is an MSD inline gas pump going to be fucked up by pumping water/alcohol through it?

 

My question was more pointed to the quantity of water/alcohol that would be injected. I understand that you have something to set the injection point, but do you have a way to meter the volume and do you know at what point the volume would become unsafe for the motor ?

 

I have no idea how much water/alcohol is too much, hmmm now I know what you're asking. I've heard something like a 1:6 ratio of water to gasoline, but I'm not quite sure how I would verify that I was actually delivering that ratio. I'll have to think about that.
