Be careful about Marvel Mystery Oil as it can seperate in your mixture. Also a 50/50 mix should not need any oil lubrication, it's the high concentrations of alcohol that needs it. I believe that the second gen Buschur kits can handle the water/alcohol mixtures with no problem. I think you better check with Buschur on that one.

 

I just ordered the kit from Al 2 days ago and I asked him about which oil was being used and he told me I have the 3rd gen version and it doesnt need it.

 

hi guys.

i designed my own system early last year and installed it on my car (2003 evo, pretty much stock, with homemade exhaust and tuned to 11.5 AFR using HKS super AFR).

i run the stock ecu with no boost controller; i wanted the water injection not for more power, but for reliability. i basically only arm the system when i am on the track (i am a senior instructor for the PCA, BMW, NASA, etc) or if it is an extremely hot day and i am boosting a bit on the street.

i mounted the system in the trunk; it draws off the window washer tank; i am using a high pressure pump (100 psi) with check valves. the system is adjustable as to what boost setting it comes on at (set currently to 12 psi). i tried out many different nozzle sizes, and settled on a 5 gph nozzle for my application.

i am very happy that during a 100 degree track day, i can go out ***** to the wall, with the intercooler spray on "auto" and the water injection system armed; i run straight water in the window washer reservoir, and it easily lasts for a 35 minute session with water to spare. the car appears to show no power drop off as one usually experiences on a hot day with a highly boosted turbo car; runs extremely strong and gives me lots of peace of mind.

i like the technology; i had fun designing and installing it into my EVO!

sounds awsome...Any pics?

 

hello again.

i took a few quick pics (as requested) of my car with my custom-designed water injection:

1st pic is inside the cockpit. the blue toggle in front of the gearshift is the arming switch for the water injection. flip it forward, and it lights up blue in color when the water is flowing. its small and fairly "stealthy"

2nd pic is in the trunk where the pump is mounted and i popped off the cover so that you can see the window washer reservoir.

3rd pic is under the hood. unless someone is knowledgeable, they probably won't notice anything amiss.... if you look at the aluminum tube going to the TB, you can just see the 3/8" ID polyflo tubing and fittings coming in from underneath. you can also see the adjustable pressure switch slightly behind the valve cover, and can just see the relay control mounted just under the strut bar brace up against the firewall.

i ran all the heavy wiring under the body in armored #16 SJTO, alongside the 3/8" polyflo tubing (very tough industrial stuff). i installed this about 17k miles ago, and has survived thru winter and track events and daily driving without a single problem. i'm really happy with the outcome!

any more questions, and i'd be happy to answer, if i can!

Just from the looks good job first of all but I do have a few questions in what I am looking for to be sure it would work for my needs. I am guessing this is just a flat on / off type system or do you have some sort of pressure sensor or item tapped to make it a progressive flow? I would like to feed somthing a extra injector output to monitor and regulate the flow.

 

i have the aquamist 2c using 25% methanol. the whole thing is being controlled with the xede. i gained 15 whp with shiv's tuning last week on a mustang dyno. not the first power mod i would do, but it helps, once all the other mods are used like exhaust, cams and ems.

 

hi.

i designed it for my use, which was primarily to be a safeguard for the engine during extended track use; i.e. during a hot day (140 degree surface track temps) prolonged running at max stock boost pressure; i wanted to greatly reduce any tendency for detonation to occur; plus i run 93 octane, not 116....

therefore, i tuned the system with an adjustable pressure switch, to come on at a preset boost level; i went thru quite a few nozzle sizes until i settled on the correct one.

i run straight water or occasionally a mix of water and window washer fluid (winter time).

it is not an adjustable flow system; it comes on (at the desired preset point) and sprays until the boost drops below the switch setting. simple and effective, at least when used in this type venue.

car runs really really strong, even on those hot days. and doesn't surge and pull back the power level as it used to when running long and hard and hot....

hope that helps you a bit!

I have a snowperformance.net stage 2 kit.

I was using it on my 2G eclipse. Now I would like to install it on the EVO for the same reasons as mentioned above....high speed autocross events.

So my evo will be stock but with H2O injection.

I have a 225, 325, and 625cc injectors. For a stock evo adding smurf **** for chemical intercooling only what size nozzle should I install?

 

Buschur SMC enterprises kit .. @ 15psi w/ 100% meth

 

I just rode in my buddies Evo 8 with the Buschur Alky kit and all I can say is WOW that is a nice setup with the stock turbo the car pulls like mad.. I am convinced I will be getting one soon.

 

Pretty sick kit huh.. Is he using 100% meth or 50/50? and what is he set on.

 

Why did you choose to use the Winshield washer res. instead of the I/C sprayer up front? dont plan on using your wipers again?

 

I just installed the buschur kit this weekend and had big AL tune her on the road. Man did that thing wake up. I promptly went to the dynojet ad put down 250whp and 245tq. Not bad for 93octane and some alcohol. He tuned it for 10.9:1 on the street and on the dyno it went off the scale, so it is definitely a safe tune. There was more power to be had (he didn't even mess with timing), but the car is strong enough and I would rather have a nice margin of safety than a few extra ponies.

I am going to VIR next month, so we'll see how this kit works for extended hardcore use. Why are people using water? I thought alcohol was better for cooling the intake charge.

 

Water has a higher latent heat of evaporization and will help you run the car cooler.
Alcohol gets you more octane.

Which one is better?
