Water Injection

[Simon Quested]

Hi Jason &  All

I'm using (well trying to) a fuel injector, But I think the one I 
have is dead =-(

Tap water for me unless anyone has a good reason not to.

Atomized is the plan.

I've seen a simple set up that uses a boost activated switch to turn 
on an injector (not pulsed just ON)

I think it only needs to be higher than the manifold pressure plus 
a bit more to get the liquid atomizing from the injector. 

I guess that the colder the water the better as it will have an 
intercooler effect as the water mists, however I doubt it will be 
cold enough to make much of a difference ?
