Where Do I Position My Water Injection Nozzles

I am thinking of running one pre-turbo and then one in each runner.
This discussion of pre-compressor injection was emailed to us by a member on here asking about it. For years everyone has been running nozzle just before the throttle body. While this works fine. A few years ago we found there were more gains to be had by also running water methanol through the turbocharger or centrifugal supercharger in combination with nozzle(s) before the throttle body.

A great article to read on this which goes into more detail is

Positioning The Water Injection Nozzle

I great recent example of this that was recently in the magazine was this Corvette which recently broke the record becoming the fastest pump gas C6 Z06 that went 8.80's over 150 MPH.

Here's the link to the article.
