Is it possible to use a standard injector for water injection?
this way you could vary the amount of water with the throttle.
i have an old injector from an XE to play with, does anyone have the specks, etc?

I used to have water injection on a 351c years ago. It actually worked well but it worked of engine vacumn not by a injection pump. The amount of water used was very little but it controlled pre- ignition well.

Pintle in injector would corrode also.

Water is way thicker than petrol spirit.I have used a BMW type washer bottle and mister/ fogger nossle from garden irrigation system.. The BMW type pump works better at pressue [83/5 model] good for intercoolers too...

That is what i am worried about spalding, but wouldnt it be made from stainless steel?
How much was the BMW pump?

BMW washer pump? Cheap as Pick and ...Pay... $2.00.. The pump has a scroll action rather than centrifical so can pump at some pressure...

Cool, think thats the way to go, just need to find out if the injector can handle it.
Another question, the reason I want to use an injector is so I can 'map' its squirts on a dyno (I will use pulse width modulation (PWM)) to obtain the best performance. Does your setup pool water in the intake when the throttle body is closed or how do you prevent this with a fixed nossle?

Na in my case I use it for an intercooler spray in a WRX and I use a foger nossle's off fern house water equipment..I guess so long as the bottle and motor/pump is below manifold you should be right..

I don't think they are stainless, but dont hold me to that , ask a place that services injectors they might even throw some your way to play with.
