Using water injection instead of an intercooler?

[keithmac]

Yeh I`ve been having a bit of a dig about and it does seem a good solution seen as most of the time it`ll be driven off boost anyway.

I was looking at the Aquamist 1s, just a boost switch to come on at 5 psi, seems a good starting point.

I`ll be using a washer bottle in the boot with de-mineralised water (don`t want a false afr reading), take it the VW screenwash pump will be up to the job for priming?
