Water Injection

[Roy]

Hi all

Have been reading a lot about water injection and how
it reduces detonation.  To run high boost I think
water injection is the way to go, but as stated it
must be in atomised form and not produce steam.

So where is the best place to inject it and just one
injector or one per cylinder ?

Before or after the turbo ?

If after the turbo would it be best before or after
the fuel injectors ?
