Well I got a water/alky injection kit.. Well sorta of a home made from from pumps and lines and all that I got..

I'm just needing to know what kind of nozzle you guys run!? I'm looking at a 9.5 gph nozzle?

Whats the GPH the nozzles are rated for? Or CC

How long of a shot is safe.. where is the best locating to mount the nozzle?

10gph nozzle is equal to 660cc. Mount the nozzle in the TB elbow.

how long of a spray would be safe?

Might want a tad smaller nozzle like a 7gph nozzle. Your going to want it to spray whilie your under boost.
