I have a ctsc @ 13.5 psi circa 400 to 450 bhp at the crank with an aftercooler.

There are two nozzle so I presume the smallest is the best one to use?

 

The small one wont do shit AJ, it would be virtually pointless. You should have got 3 total with your kit. Small/med/large. 140cc/330cc/550cc. If your going to spray mostly water, then I recommend the med. If your going to spray 50/50 or higher meth concentration then go with the large nozzle.

Did you ever get the kit to work? Never got a reply on your half a dozen other meth threads

 

Hi mate haha i know, i only got two jets with my nozzle looks like i have the newer kit which only comes with a medium and large nozzle.

No i think the controller malfunctioned />

I will just use the larger one then, as ill be running 40/60 meth water.

 

interesting so the medium jet is the way to go i drilled the small jet out a bit but smaller than the medium jet. wonder if i should switch back car was running rich on the 50/50 mix but was lean on the small jet should i run the medium jet and back off the fuel pressure?

 

I ran the largest size nozzle with a 70/30 meth/water mix, turbo @ 13psi

 

This is about the ratio I ran as well with the large nozzle.

** AJ, More fluid = more cooling and detonation suppressant, but too much water isnt really a good thing, so calibration % between water and meth, plus nozzle size should be considered both. At 60% water I might stick with the Med Nozzle. Best thing to do is try them both on the dyno and see how things look.
