so is it better to drill and tap your own intake or buy one like scheids?

 

-------------------------------------------------------------------------
My suggestion to you would be to try installing two nozzles in your air horn to start and see how that does for you, or drill and tap the intake as the Members have pointed out. The Scheid System I am running is pretty advanced and may be more than you need, but it sure does a good job!

 

ok thanks John_P!

 

but as ACE told you no way needed unless you want to blow the block apart

 

So, does anyone have experience with the LaBonte kit?

I don't think I've ever seen it mentioned in the 5 or so boards I frequent...

John-
do you have a pic of the pump installed?

 

Eric I looked at it but its basically the same thing as a Snow System!

 

Yes, kindof. The way I understand it, the Snow's controller is capable of 2D mapping, while the LaBonte does true 3D...and the LaBonte is $350 cheaper than Snow.

Here's the Stage 3 MPG Snow kit for Cummins:

However, the higher pressure and volume pump from snow can NOT be used with the stage 3 system.

It really seems like you aren't getting much for $1,000 from the Snow kit, unless I'm missing something.

Every kit is basically the same...including pump, solenoids, nozzles, lines, tank and controller. Sure, there are some variations among components, but I don't see where the price difference comes.

From what I have found so far, is that the LaBonte kits have as good of specs as any company out there (or better) for a cheaper price.

Sorry for the delay in replying to your post Sir!

To answer your question,......no I don't have a pictue of the way my pump is installed. But I can tell you that the Scheid System has their large water pump attached right to a three and a half gallon water tank. I have mine in a plastic Rubbermaid Tool Box right behind the cab of my truck. From there the main water line goes down through my bed, and under the truck and up to a
"distribution block" on the driver side of the engine, just behind the air horn.
Off that "distribution block", there are five (5) stainless steel braided lines that go into each nozzle which on my truck are machined right into the cylinder head.

Hope that helps you understand how it is set-up. BTW,....the Scheid Water Pump is alot bigger than the RV Style Water Pumps that come with the Snow and other water systems. It can put out up to 1,000psi versus about 200-220psi for those RV style water pumps.

John,
Sir what do you during the winter months since you run just straight water in your system? Do you mix alittle washer fluid or do you just drain the system????

Thanks,
Buddy

I have done it both ways Buddy. Fortunately, the temperatures don't get that low (cold) here in eastern N.C. I am sure if I lived up north or out west, I would have to flush with something like winter windshield washer fluid or something like that.

Hey John!

Is the Scheid pump with reservoir something similar to this?

http://www.northerntool.com/webapp/w...9764_200329764

This is a made in the USA pump with integrated 2 1/2 gallon reservoir capable of 1.4 GPM and 1,600 psi...from the Devil's Own calculator, that would be very capable of feeding 700+ hp at 4,000 rpm and 60 psi boost.

An additional 4 gallon reservoir is available for $82.

I'm somewhat contemplating going with a pump like this and about 10 gallon reservoir. Combined with a set of 4 - 6 high pressure fogging nozzles, it would run around $500.

I think it would be fairly easy to combine this with a progressive controller and solenoids from your company of choice.

Going this route, you'd probably have $1,000 in the system, which is right at the price of a good Snow unit. However, it would be a 1,600 psi capable system with true fogging nozzles and progressive control for towing/performance/etc.

Thoughts?

Eric:

Yes Sir, that is somewhat similar to what I have from Scheid but my tank is larger than that. That looks like a good unit from "Northern." No offense to the RV style pumps that many of the aftermarket water injection companies use, but they only put out a maximium of 200-225 Psi. When I went to higher horespower (750+) we found those little pumps just could not keep up.
If you add more nozzles, then the pressure drops down too much. You can add another RV style pump, but that still didn't get me up to where I needed to be.

Anyway, I think that unit you posted up from "Northern" would work real good for you Eric. I sure like my Scheid Water System. I really like
the "adjustability" of the pump so I can "tune" the pressure to what I need depending on the temperature, humidity, barometric pressure etc. It looks like that unit you sourced out will do that too.

Good job Eric!

I now have a 25 gallon tank I place in the bed when towing. I use 5 to 8 gallons of water an hour with my system. When I will not be towing I pull out the 25 gallon tank and just have a 5 gallon tank. I seem to atomize well with the 250 psi pump I have but that would be due to the relatively low flow I guess. At full water flow I am flowing about the same amount of water and fuel and see 20 to 40 degrees drop in intake temperature and 100 to 150 degrees drop in exhaust temperature.

I would love to get 6 EGT probes and see real world temperatures and the reaction to the water injection.

 

From what I gather reading on this thread, water injection on a basic level is a waste of time because it doesnt cool all the cylinders. And also impractical because of the water useage 5-6 gallons an hour wouldnt get me very far if they really use that much water. Maybe I'm not getting the whole picture but thats what it looks like from this discussion. So what's the best way to cool egt's on a truck thats used for hard towing on a regular basis?
