Where/how to mount pump for WI?

[Lancer]

Finally got around to installing the WI kit but couldn't decide where to mount the pump. Found a good spot next to the A/C condensor but I need to drill holes and it's really tight for a drill. Then I thought about onto the bumper.Anyone have pics of how they did installed it?

[Lancer]

Nevermind, I figured out a spot. Right next to the washer tank in the engine bay. I accidently broke off the boost gauge hose at the fitting that goes into the s/c manifold. So I put the spray nozzle in the side of the s/c. I figure it would cool the air where it's hottest and the expanding water vapor should give me a little more boost. I heard a lot about the s/c rotors getting worn by having the spray going through them while they are turning at high speed.I only have to finish the wiring and figure out how to tap into the washer bottle. I'm thinking of tapping into the lines with a 'T' connection and a check valve after the 'T' so I don't suck air.Here's a couple pics.I ran the hose inside the front frame just above the radiator then had it come out through the access hole for the A/C lines.Don't miss this pic, too.

What are the specs on the water pump? Specifically, what is the discharge pressure?I have never installed a WI kit, but theoretically, you would want to inject water into the intake downstream of the supercharger. This would prevent excess corrosion or pitting. But, since the air is at a higher level, you need to make sure that the discharge head on the water pump is at least 11psig (that would be the S/C pressure plus a little more). Install looks great!

High pressure 120-140 psi diaphragm pump with viton valves.I think it should do. I e-mailed the company that makes the kit. And I'll call the local tuner shop for thier advice. I've been wondering how safe this set up is. Looks clean though!!

[engineertwin2]

Diaphragm pumps are good positive displacement pumps. You'll get a fair amount of slippage (losing as much as 25% of your injection volume) if the pressure in the manifold is near the max discharge pressure. Interesting to note, you won't get 120 psi unless it requires it. Basically, it can provide up to 120 psi before it stalls out.It's good that the valves are viton, but what are the wetted parts of the pumps? I'm guessing probably plastic or composite. You are lucky if they are stainless.It should remain fairly safe provided you don't over inject. Are the nozzles included atomizing nozzles? Try to look up and research psychrometrics (see dew point). You only want to provide just enough water to saturate the air but not leave any free water. This will vary with temperature and relative humidity. Too bad this isn't a variable stroke positive piston pump with logic that can vary the stroke according to ambient conditions...that'd be sweet...do they make an intelligent WI kit?

What brand is the WI kit? I think a lot of people with trix put the WI nozzle in the CAI, it sucks our SC doesnt have a intercooler :/

I never thought of putting the sprayer where you did, Lancer. I have my boost guage line there. I mounted my WI pump way down near the bottom of the washer reservoir under the bumper. Looks good!

[northvibe]

did either one of you use your windshield spray tank as the reservoir? I hear the 50/50 water/alcohol mix or a washer fluid thats about that will work good for both cleaning the windshield and WI.

[Lancer]

Mounds of info! Thanks!I'm thinking, too, tht it should be alright. I'm actually more worried about the pressure increase inside the manifold than the water accumulating. I figured that the air is constanly moving very quickly into the engine that it wont have time to collect anywhere.The nozzle IS a atomizing one. Very stout looking. And with the high pressure I should get a very fine spray.I am using my washer reservoir. Tapping into the rear spray line instead of drilling a hole in the thing.Quote, originally posted by damronjr »Mine is in the CAI tube. I never thought of putting the sprayer where you did, Lancer.

First things first, though.

dang lancer your a mod maniac i hope your going to be at the August 5th meet in MN? I HAVE to see your ride!!!

damronjr what do you use for the "water"?

I bought some before but it had some stuff in it youre not supposed to use, so I gave it away and found this stuf on my trip back from Dallas at a gas station. Never could find it before!

WI???

WI is great for NA applications too

Got all the wireing done and I tapped straight into the washer tank from the rear pump. Just need to put a 'T' with a check valve in there. Have been running it for a week now. The engine runs a lot smoother at WOT now and there's a little more power that you can feel. Aslo, I get to 10-12psi faster with the wi on then off.So far I guess it's safe to put the nozzle in the manifold instead of just before the throttle body.I hooked up a switch so I can control it more and ease the wear on the pump and sylinoid.Here's a few more pics of the completed set-up. Just have to make the wires 'pretty'.

[damronjr]

****, my engine bay looks like a birds nest! I can't even think of where to run the wires so they look decent. Need to make a new harness!

[NascarXprt]

ha! yours looks like a birds nest mine really looks like one especialy after i was in water back to topic:man that looks good Lancer. now all we need are some #'s of what she is capable of doing and what she can do.

[Faultline]

Hey Lancer it looks good.I wouldnt worry about water atomization and all that, at least I dont. When I 1st put in WI , I was using a welding nozzle which was just shooting a stream of water right before the TB , after where I put my MAF. The idea was that the turbulence of the air would diperse the water/alcy. I was squirting too much water at 1st, and my motor would just start to bog down. I was using, and stlill am, the stock pump from the windshield washer resevior. I am using a smaller nozzle now. The nice thing about my set up is that I have a hobbs pressure switch plumbed into my IC pipe after my intercooler befor my BOV. I actually have 2 of them . They are adjustable, and will turn on the pumps at any pressure I set them at. One of them is for an auxilery fuel pump in my fuel set up, that comes on at 0psi. The other switch is for the WI. It turns the water pump at 8psi. I have a dual stage boost controller set at 6psi and 12 psi. At the lower setting, WI never comes on . At the higher setting, It comes on at 8 psi.This way, The WI is not on all the time, and only comes on when I need it. Btw, I usually just use straight rubbing alcohol for my mixture. For what its worth.

[Lancer]

Hey! nice to hear from you again! It's been a while.Thank's for the info. Mine is set to run @ 5psi +. When the system is switched on, the relay turns everything on, but the pump wont start flowing until the syliniod is opened by the pressure switch. I was thinking about just using the stock pump, like yours, but I didn't feel like messing with the harness to it. And the pump came with the kit so why not use it. And I want to still be able to use the washer fluid for the windshield without having to rig up a bunch of stuff to control the flow.I was looking at a adjustable pressure switch. But for now I just want it working.You think using straight rubbing alcohol would be alright with me? I'm already running really rich. Lots of black smoke in the exhaust and almost peg the rich side of the a/f guage. (yeah I know I need a wideband a/f meter).

(yeah I know I need a wideband a/f meter).[/QUOTE]Out here in CA we have 91 octane at best. I showed Stafford a book I read about turbocharging, that in the WI section , It showed that there was no more value in preventing pre detonation by mixing more than a 50/50 alcohol/water mixture. Stafford pointed out to me , that when the book was written, they had higher octane gas, and that he liked to use straight alcohol to boost the octane a little. I dont really know what is best. I have heard that the eaton m45 sc looses its effeciency dramaticly after 10 psi, meaning that after that point it really heats up the charge air. If you are ruiining up to 12psi, then you need all the help you can get. Running rich like you do sounds smart to me, and as far as straight alcohol??????????lWhat you are doing now sounds fine.

[Mrizzle05]

Well we gonna get any more updated pics or some video runs so we can see the car in motin?

[Lancer]

All I have is a digi cam that takes only 15 sec. videos. I'm gonna keep trying at the track, though. Last week I showed up and the track was closed. And the weather for this Friday looks like T storms. Faultline, thank's for all your help. It's much appreciated. Only on really cool nights (I'm sure I've maxed out the s/c. So what's next? I want to do cams and a Stroker kit to a 2.0lt, or higher compression pistons? To go with a hybrid s/c. By the way, is your record still 14.8 or have you squashed that by now?

I dont think that I have been to the track in over a year!I have never gotten better than that. I sort of got frustrated at the track because my times were not that good, in the sense that my 60ft times range from 2.4 to 2.6. It is really hard to launch a fwd turbo car, and I hope you do better with the SC. If you look at some of the times that Hope puts down in her Subaru, you will see that she breaks into the high 13's going 98mph. I was going 97mph just to get my time. The difference is, is that her 60fts were like 1.8. I kinda dont want to go back to the track util I figure out a traction solution....I still think about LSD's and how I want one. I think that the power is more linear in an SC, and you may be able to get a 2.2 for your 60ft's. If you do, you will respectably get into the 15's and maybe the 14's....its all about the 60fts. Each 10th saved there will save you a couple at the end. When you beat my record, I will have to go back to the track, LSD or not, and try to do better Have you thought about nitrous to go with your SC??

[Petrucci914]

Damn, Lancer. I have to make my way down to Appleton sometime and see your ride. When I graduate this year and get a full-time job I want to either get a Supercharger or the Hass Turbo. I have to do something with my tranny,though. I don't like how she shifts. Do you shift yours manually now that you had yours rebuilt? I don't know if it'd be cheaper to have Level 10 do something.

[Lancer]

Faultline,I'm VERY confident I'll get into the 14's. Got a new avitar for when I have a time slip to prove it. With the fast shifting tranny upgrade and the torque converter raised to a 3k stall, I just have to mash the gas and the car just chirps a little and takes off. I'm in full boost (9-11psi) by 3500rpm. First gear shifts just before 7000rpm. But the power seems to level off around 5500rpm. Third gear pulls a little better then second.Umm, LSD... I have started to notice that the WI is boging the car just a little. Must be broken-in and flowing better. Need to turn it down a little. I have thought about nitrous, but I don't think I'm gonna go that route for a while. There's a lot that I can still do to the s/c & motor first to get some really decent hp. I want to try cams next, then start building the short block and head.Petrucci,I just put the car in drive and let it do all the work. I'm not used to shifting the auto manually. I've tried it a couple times and I think it works better if I let the car do it. Level Ten is a really good place. But you still have to pay someone to remove everything ,unless you know trannies well enough to do it yourself. Then you have to ship all the (heavy) parts to them to rebuild it. T&A from MO had it done and just raves about their work.You have to do some calling and see what's available in your area. Or you can bring it to Bruce @ Aamco here in Appleton. Now that he know's everything about our trannies, it shouldn't take him a month to build it up like mine.
