Begle's Water Injection

Postby Begle1 » Wed May 28, 2008 2:47 pm

Alright, I've gotten far along enough with my water injection system to post pictures.

Water reservoir.

Image

Pump.

Image

Image

I bolted the Cooling Mist controller behind this kickplate, where I had my inverter. Now the inverter is on the steering column...

Image

I got a milspec laptop programming things. Semi-permenantly wired it to the inverter.

Image

Water injection wiring harness through a DIN rail.

Image

Image

Boost pressure transducer.

Image

Image

My auxillary fuse block is getting full...

Image

Here's the biggest work in progress. I sourced some stainless-steel braided lines and some check valves from Swagelok. So I'm going to move the solenoids to the fender, mount the check valves directly on the nozzles and connect them with the stainless lines.

Image

And it's not enough. I need to get a pressure reading at the nozzles to see how bad I'd bogging down the pump at 40 GPH. But, the same system is adaptable for 1000 PSI water injection, or nitrous.

Looks good so far. Where did you get the solenoids, and how much were they?

Those solenoids are $40 a piece from Cooling Mist. I gotta get them onto the fender; I'm sure they're not too fond of the heat.

Think they'll work for air? I need 1 for the air horns and 1 for my exhaust switcher valve.

I'd assume that they'd work for air. I think they're only rated for 200 PSI though.

I've contemplated moving them to BOV duty after they get replaced with 1000 PSI nitrous solenoids....

That's plenty! I'm only going to run about 120.
Thanks for the info.

looks great begle! I love seeing creative work rather than some guy that buys all bolt on stuff for their truck. Do you have any plans for more pressure? Great work.

Can you show any close up picks of the computer and programming? what are you using? labview?

The laptop is a 850 MHz Itronix IX-250, which is a predecessor of the Panasonic Go-Book. I got the Itronix because they're $130 off of eBay, and they meet military specifications of 140 degree heat, vibration, water, shock and jar resistance. It also has an illuminated keyboard and touchscreen.

It connects to the Cooling Mist "Smart" controller with a serial cable. I'm using the software that came with Cooling Mist's controller, which is limited but constantly improving.

http://www.coolingmist.com/detailmain.aspx?pid=1099

Back at Arizona State they had a couple hundred LabView-compatable National Instruments DSP boards floating around... I was definitely tempted to sneak one or two into my backpack, but I'm sure they wouldn't have been too happy if they caught me walking away with $400 DSP's. The Cooling Mist controller only costs $200.

I'm going to get a pressure sender out of this set-up to make sure that it's working... I'd imagine that it's dropping below the advertised 150 PSI at 40 GPH of flow, against ~30-40 PSI of boost pressure. I can see the same wiring system controlling two or three nitrous solenoids in the near future. :lol:

I got that hydraulic pump too, that I wouldn't mind converting over to water...

Begle, I think you have found the answer to my VGT turbo problem. That system looks to me like it will do everything I need it to do for controlling my turbo......better than the megasquirt I picked up. Dirt cheap too.

It dosent need a laptop plugged into it all the time does it? That is just for tuning. It is like any other ecu right? tune and burn to ecu?

I have found everything I need to make my project work I just need to figure out how to monitor turbo shaft speed.

but that is for my thread...

Any how, great work Begle! Just throw that hydrulic pump in your tool box and I am sure you can find someone at ASU to make a starter drive it. We have a machinist at WMU for stuff like that.... Just tell them it is for a student project....

Dude! Read the fourth post!

:lol: :lol: :lol:

I even linked to it! Over a year ago!

The laptop is only for programming it. Once you get it programmed it's autonomous.

But the laptop also lets you monitor what solenoids are open when, and it works as a datalogger and displays virtual gauges of all your inputs. And it looks cool to be fiddling away on your laptop between stoplights...

Hey!
Nice work!
Where did you source that groovy pressure transducer? I have the MAS controller for my Snow, so I need a pressure transducer to feed the controller variable voltages.
Thanks!

That transducer isn't really the right one. But Arizona State had a limited selection.

It's good for 150 PSI, but it also outputs in 4-20 milliamps and requires 24 volts. So I had to use a resistor to get a voltage and I had to find a transformer out of the thrift store to run it. I don't think the way I wired it is supposed to work, but it does so far. :?


eBay has a pretty good selection of pressure transducers. There's quite a few that go for under $100. I think that good ones can list off-the-shelf for a few hundred.

Thanks, I'll check ebay!
