Pre turbo vs post Water injection
 

Im asking if anyone has tested pre and post turbo straight water injection setups to see what surpresses knock better with a air to air intercooler? Mainly want to know by how much (deg timing) one setup betters the other, in knock surpression. Thanks

Re: Pre turbo vs post Water injection
 

injecting water as close as possible to the chamber will offer more detonation suppression.

And timing can only be determined on a dyno, regardless of what or where you are injecting.
