Homemade water injection kit......
Hey guys, I'd like to sharre some info on my homemade WI kit....Very simple but effective.
Quick rundown- Car = 89 Ford Mustang Engine = low compression 306ci w/ a Vortech Strim @14 psi (non-innercooled) I am using this temp meter : Omega HH12 Here's the WI kit rundown- -Hobbs switch -Alum tank -NOS solonoid/and paper fuel filter -NOS Nozzle -Various braided/teflon line, and fittings ect... More Pics: Here's some #'s: Now for boost, i was only concerned with intake temps, so i measured at the throttle body with 14psi and 91 octane... I made 5 verifying runs per test, just to get more info... Under 14 psi, i saw between 243-251 degrees, respectivley. NO WATER With the water turned on, (.034 jet) i saw temp drops in the 20 degree range. About 230-234, respectivley. Not too bad, but come on....LOL A trip to the local parts store got me some more jets..Next up was a .044 and boy did it work..Again 5 runs with no water @ 14psi, and all were around 250 degrees...Flipped the water on, and made 5 passes to back it up....All 5 water runs were in the 180 degree range ! Thats a drop of 70 degrees. Sweet! I only logged 1 time and that was last weekend. I plan on a lot more tuning....Running 14psi with no cooling and crappy 91 octane is always fun...LOL I have not taken the car to the Dyno or track,(with the water) but i will soon. My best time at the track is a 10.98 @ 128. Thanks, Miles

So what was the total cost and time spent making this? And do you have any thoughts of trying a water/methanol mix? I am very new to WI, so I am full of questions; but it seems very intersting.

I would say total cost is in the $80-$100 range...My buddy welded the tank for me (out of scrap alum), and the most expensive part was the NOS solonoid....
I have not tried any meth/mix yet, but i am definately going to mess with it... One thing to remember, i am using boost to force the water into the blower..To inject water into the intake (pressurized) i would need a pump, ect...This is more crude, but seems to work well for an experiment....LOL

I do not have any safety stuff on it....But i drive this car mainly on weekends and such, so i watch it like a hawk....LOL Im not sure how much water it holds, but while i was testing we drove the car hard for about 3 hrs and the tank went down like 1/2".....
I never went to the track, because i found out My harness is now past its legal date.....uggh. Sucks but i gotta pass tech to run.... And yes you are right, i am using boost pressure to pressurize the tank, wich forces water into the blower through a NOS nozzle...

I had a similar setup many years ago on a Kawasaki750 turbo. Non-intercooled aircooled engine running high boost brrrr.....
Boost pressure was pushing water mist just before the compressor wheel. Worked well, but was heavy on water usage! |

tank? Methanol corrodes aluminum, you don't want that stuff in your engine. Or am I mistaken? BTW, awsome looking work, very pro indeed! :!: |

Filter, nozzle
I had a paper filter disolve in water/alchohol. Keep an eye on it. At least, you have a clear filter. So, you can watch it.
Have you tried the Carr/McMaster nozles? that's what I use on my homemade system. |
