Water Injection Nozzle Placement?

I have a Stage III kit thats been collecting dust. While the truck is down I'd like to get it installed. The HMax y-pipe has bosses cast into each side. Should I put them there or in the intercooler tube?

Re: Water Injection Nozzle Placement?

that will be a good place to put them... Thats where I used to have mine, but the stock Y pipe started to wallow out. Bungs would be fine though.

Is that what those bosses are for in the Hmax Y-pipe?

And is it a bad idea to put the nozzle(s) before the turbo? I've always wondered why they are put post-turbo.

Re: Water Injection Nozzle Placement?

The water will cause wear on the leading edge of the blades pre-turbo. And compressing air with water displacing the overall volume is not effective. Adding water to near ambient temp air is not gaining the best use of heat displacement pre-combustion.

Re: Water Injection Nozzle Placement?

A lot of pullers will put one small jet ahead of the turbo to keep the wheel cool. In fact Columbus Diesel recommends it. But that only applies to competition only vehicles. I would not run a jet ahead of the turbo for cooling on a tow vehicle as it will cause wear.

Re: Water Injection Nozzle Placement?

I agree with you on the cooling aspect. Small jet for small micron particles. Not for the daily driver.

Re: Water Injection Nozzle Placement?

I also need to add that the only ones I know running a small jet before the charger are also running high pressure systems, NOT low pressure off the shelf towing setups. I'm talking 500 to 1200 psi.

I would imagine at those pressures the water would be atomized to the point it wouldn't damage the compressor wheel.

I'd have never thought that water would cause turbo blade wear. Learn something new here all the time.
