Water Injection Systems???

Man that cant leave much wall left in the nipple. Doesn't sound that strong to me. Not something I would want flying into my motor.
 
Nipples aren't the way to go... besides, you have to machine for the correct nozzle penetration into the plenum or runner.
 
Snows kits have you account for that?!?

I was going to do the mcmaster carr thing but never worked out what flow rate to use and whether or not to use the filtered sprayers.
 
So lets move on to another subject. What are you all using for pump lube/anti-corrosion in with your water?
 
I use distilled water only and I add water lubricant at the rate of 6 oz to each gallon useing the NAPA/CRC Concentrated Radiator Anti-Rust and Water Pump Lubricant #095335
 
The Snow Kit that Matt sent me and the all the nozzle's that I will be useing 6 #175 nozzles and 2 625 nozzles with 2 pumps at 220lb pressure.he said that we will be able to flow 3200 ml per min.I don't know what that converts to.

Dale your going to loose a lot pressure trying to feed 8 nozzels with those two pumps, it certainly isn't going to be at 220lbs anymore. I think Jim Fulmer tried to run three nozzels with one pump and it dropped considerably.

its a 2.8 truck ... higher the psi the better i mean i need water but not as much as others do... do you think it would work for me 2 use a 220psi pump from snow or even 2 psi pumps or are they still to small
 
In my opinion why bother with setting up a sub-par system using only 200 ish psi. In my testing like mentioned above those systems can only support 2 of there nozzles.

Has anyone ever tried to run 2 surflow pumps ones outlet feeding into the other?
 
Would the second stage pump have enough torque in compound configuration?


IF you don't drop below the operating pressure of the nozzle, is there any other drawback to the lower pressure?
I know the atomization is a plus due to higher pressure, but is there any reason to have a problem running a nozzle at it's recommended operating range? Meaning, if i were to push 40lbs of intake manifold pressure, and the nozzles needed 100lbs, there would not be a danger so long as I maintained 140psig at the nozzles?

That's pretty close to 50 GPH

What do you use for nozzles then?

We machine adapters which thread into the bungs to hold the nozzles, then machine the push locks for screen clearance.

X2 - even if you boost-reference the pump, the pump overhead you gain is modest... and you still have the volume limitation.

I agree, but on the merits of flow volume rather than pressure - quality nozzle orifices have appropriate micron ratings at 100psi, so even a 200psi pump will have sufficient overhead at 100psi manifold pressure.

You can't plumb Shurflos in series (:badidea:) - their design inlet pressure is relatively low... been quite a while since I spoke with their pump engineer, but IIRC 40psi is about the limit.

Same reason why you have to be conservative when boost-referencing the pump suction.

Can you pm me a price on some nozzles?

What works better, to inject it in the runners? or into the inlet to the manifold???
 
What KInd of pressure are you guys using on the big systems? I was thinking no less then 500psi???

Just the nozzles or the whole nozzle assembly, ready to screw into the bungs?
Push-locks on top? - or NPT, 37*JIC, 45*SAE or inverted flare? Our push-lock tubing is rated to ~350psi.

I prefer spraying the runners (if you have them) because of the ability for cylinder EGT tuning.
