water injection

[JET]

Not only that, Dre tried it on his car and could not tell the difference when it was on or off. That was with a well tuned car running an AEM EMS. We have had debates on here before about whether it would work or not. I don't want to get into that again. I would stick with the proven mods. UICP and a walbro 255lp for example if you don't have them.

a lot of people consider water injection just a band-aid for bad tuning, at least for a street car

I have dynoed a supercharged M3 a couple times that runs water injection. With it off or on the power is the same. The power curve with it off is very jagged and looks like the car is knocking, with the water injection turned on it is exactly the same. He can't turn up the boost easily like you can on a turbo car when the water injection is running, but it looks like crap no matter what anyways.

We have tried some WI homemade systems here and in the long run it just turns out to be a mess and a hassle to work w/. Although it did seem to cure some knock problems but all i gotta say is make sure you don't run out of water when your trying to tune w/ WI.
As far as running a stock fuel pump, you cant run water threw the fuel pump, it will eventually destroy it. Although Shureflow does make some high pressure pump designed for t his application. But IMO like others said it is just a band aid for a bad tune, and in the long run it just ends up costing more $$ than it seems to be worth...lost cause.

ding ding ding ding, we have a winner.
alot of the 3s community uses water/alcohol injection kits to cover up for a lack of fuel and lack of turbo efficiency, it helps cool the air charge due to the fact that the 9b's spit alot of hot air, and the stock sidemounts are smaller than dsm sidemounts.
upgrade your intercooler pipes/endtanks first, it'll be around the same price when you get down to it, and it'll show much larger and more consistant gains over a band-aid tuning method.
just my $.02, but what do i know :blah:
