Water Injection nozzle size?

[deerefanatic]

Hey guys, getting the last bits of my Chummins wrapped up. Gettin ready to do the water injection. I have a Cooling Mist controller that I'm going to set up for 2 stage injection. I've got the 220psi Snow performance pump, and a 100 and 175cc nozzles...

Truck is a 12v with 188/211 (reground industrial cam) and H1c/HT60 twins with 5x16 sac injectors, 131 dv's, and soon to be racked pump barrels. I've got a water/air aftercooler that runs off of a heat exchanger (ford taurus radiator) out front. You guys think those nozzles will be big enough, or should I go bigger? I want to keep EGT's managable when towing.

Thanks for any input.

I'm going to be using 2 1000cc nozzles, I would at least get like 625cc nozzles

Will you be using the mpg-plus settings of the CM controller, or just twin nozzles?

 

[cumminsman315]

I'm not using a snow performance kit, mine will be without a controller and just a pressure switch

I was referring to the coolingmist (CM) controller. It can control two nozzles separately.

MPG-plus is a snow performance thing..... This is just for EGT control for my majorly oversized injectors.

I'll be using a 100 & 175 cc nozzles together for stage 1, then 625cc nozzle for stage 2

MPG-Plus is a Coolingmist thing

MPG-MAX is a Snow thing.

Youre right. my bad. No my setup wont have the mpg thing. I plan to start stage 1 at over 2500 rpm or over 950f, whichever happens first. Hit stage 2 at 1100f or 3000rpm

Any 1.07 CMBS or VC2 can use those settings.

 

[deerefanatic]

I don't have either of those controls. I have the Digital Smart controller.....

Would 1100* be to late to start the injection of water meth?
