Default 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...

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
