Water injection
Water injection
Anyone run water injection? This is a cheapish setup we run on one of our pulling tractors (no room for an inter cooler and they aren't allowed)
I'm planning to use water/meth injection on my 606. However - Have not sourcesd any part yet...
We use a rather simple setup. The Hobbs switch in the crossover pipe is turned on by boost (I think we have it set to ~25psi), which then sends power to the pump. We chose to put pressure activated check valves in the top of the water manifold (the things with the orange caps on them) They can be set to open and whatever psi you desire, we have them setup to open close to 100psi I believe. They also act as a safety to keep water from accidentily flowing into your intake without you knowing
Like I said, the first Hobbs switchs activates the pump, the second hobbs switch is turned on when pressure in the water manifold reaches over 100psi, which then sends signal to a little light on the dash which lets you know that your water injection is on and working.
We also have a 200psi blowoff valve on the side of the manifold to keep from dead heading the pump
Its fun to play with!
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
I've got a nice modified intake with sprayers, only had it on for a short bit though. Nailed like a monster when the mix was wrong.
Are you running mcmaster sprayers inside the brass guys?
What's up with the tapered restrictive looking way-too-bendy charge pipe?

No, the big brass looking units are the nozzles.
And here's why the pipe looks like it came off a two stroke dirt bike...
Needless to say, there is very limited space
I had one little 2gph nozzle spraying in on the 617 manifold side of my turbo housing before. I thought it was a pretty neat thing. I might would do it again sometime in the future.
I am surprised some of the high HP guys haven't chimed in, I figured at least a couple of them run water/meth.
Simpler,
It is quite possible that on your setup you might have been spraying to close to the ports and not letting it atomize enough. IIRC, you had one nozzle spraying into each port on the head?
The most effecient place for water nozzles is on the outside of the first bend in your crossover pipe, closest to the turbo.
Sounds crazy, but the longer the intake pipe you use from the turbo to intake, the more power it'll make. A couple guys I know running really hot tractors would come out of the turbo, run the pipe clear to the front of the tractor then loop around back to the intake. One of my buddies said it took 14ft of pipe on his! But he said it really really made of difference.
Just food for thought
And simpler, I took a look today and those nozzles are s.s. co. Atomization nozzles. I'm pretty sure they are cone type, and I can't remember what size they are. There is one smaller and one larger I do know

Yeah, my manifold sprays directly into the ports in the head. I really didn't get enough time to experiment with it, I'm hoping to setup WI on the test wagon to play with it again.
Doesn't a super long pipe act as a cheap laggy intercoooler?
No way to modify that turbo and clock it down?

I run water/alcohol on my w123, I dig it, there is definitely a noticeable increase in power when I flip the switch, and after running a few gallons through I noticed the engine started to run a little smoother. I have a devil's own setup, with a 3gph nozzle, and if I remember correctly the pump is set to ~200psi or so. Unfortunately I can't remember where my pressure switch is that I ordered, so I have to turn the water injection on manually by now, so I just check my gauge and don't turn it on until I have a minimum of 5psi boost, usually wait until about 7. Since I have to turn it on and off manually I usually only use it for merging onto the freeway.
I was thinking of the snow universal meth kit. I wonder if I go this route rather then modifying the front end for a intercooler.
There is definitely power to be made with W/M injection. I would say our pulling tractor picked a at least 50hp just by adding W/M.
Sassparilla, go pick up a Hobbs switch! haha, they are pretty cheap. And devils own makes a good do it yourself kit for the guys that aren't going all out.
Mikes, If you end up going that route, I think a devils own kit will be cheaper, but just as good.
I have a Hobbs switch, it's just buried in my trunk someplace

Gotta hate when your trunk eats things, and then they get lost for what seems like forever.

Try a truck with a cap, you can lose an unbelievable amount of crap

Oh by the way, I have my nozzle spraying into the turbo outlet, where the air is the hottest and has the most time to vaporize

I'd love to hook up W/M on my car, but If I get my A/W intercooler on, theres no good place after the cooler to spray.
And I don't think you'd wanna spray before the intercooler cause condensation and corrosion etc..

No thanks, I don't like port injection for W/M. Its not as effective as port injected nitrous
Maybe port injection on a long runner w115 manifold, with the nozzles near the top of the runners, otherwise there's no time for the mixture to atomize
Couldn't agree more sarsaparilla. Went to some tractor pulls last night, and several tractors wheat down the track shooting a 12-15" flame out the stack, they REALLY need some water on those things!
