I know what water methanol injection is and how it works. I am just wondering if it can be used on a daily driver? I have looked at all of the kits and I want to know if there is a way to toggle the system on and off so that it is not wasted on trips to school or if it is best to just leave the system on at all times. Or is it just best not to have it on a daily driver at all? Are the kits hard on a motor (in my case a 4g63)? I have a 97 GSX that is all performance.

yes, it's ok for a daily driver. it depends on what system you get. some of them work like nitrous systems that only come on under certain throttle positions. daily driving doesn't usually use a throttle position that high so it won't be wasted.

Most of the kits I've seen have a boost sensor. That way it only comes on when you need it, at higher boost to prevent detonation. Obviously, you don't drive to work with your foot to the floor do you? If not, it won't kick in. Heck, most of them even have a little light you can mount inside the car so you know when you are running low. And yes, you can just put a switch on it to turn it completely off as well.

I agree with the above absolutely. My car CAN'T be a daily driver without water injection.

not everyone has a daily with a holset turbo though either :P

Just to get this strait, that holset is the one out of the early 90's dodge ram diesels, right?

And holy hell man, how much boost are you running on your dd to need it that bad?

Well, a kit that can do exactly what mine does can be had for $200-250. Water is free. Wiper fluid is cheap. Race gas is not.

My kit is VERY simple.

A shuflo 100psi pump: $90
A normally open Hobbs switch from NAPA: $35
Fuel injection hose and wormclamps: $40
GOOD check valve: $25
2 nozzles: $20
Wire: $5

$215 total. The hobbs switch is by far more reliable than other devices out there to control water injection. It is basically a oil pressure sending unit but normally open instead of normally closed. No relays to fail, no solenoids to fail. This kit has served me for YEARS. Water injection suddenly failing in the middle of a hard pull is NOT what I'm interested in.

do you run washer fluid or the actual mix?

Right now I'm running 80% water 20% pure isopropynol. You can get 98% Iso from wal-mart in quart containers.

Could you by any chance post some pictures of your injection system hookups, etc? I would like to see your setup.

what size/brand nozzle do you run?

Here: AquaStealth nozzles.

A 3 GPH and a 5 GPH.

thanks for the link!! :beer:

do you have yours in the tb elbow or intake manifold?

The larger one at the TB turn in. Like a TB elbow but better (I have an n/t TB). And the small one farther up the intercooler piping by 6ish inches.

i've read that it's better to have one in the intake manifold? do you prefer they be in the piping or you just didn't want to drill and tap a hole in the intake manifold?

how so ??



let see i still have most oem stuff on my car running more boost almost 20ish and running on crappy 91 octane and still not water injection.

the downside to this is that i have not driven my car over a year now. :( :crying:

Yep. I'm running 30 psi with pumpgas. Water injection made the difference. I couldn't run this kind of boost on pum gas without it. I wouldn't have bought a Holset if I wern't looking for more flow that 30 psi and a better turbine wheel gave. I had the small 16g on this setup before and I could run up to 22 psi and not need the water injection. . . But yea, water injection is streetable. It makes race gas tunes streetable. It makes high boost streetable.

There is a time and place for it. . . Well, even if you don't run high boost, 100% intercooler efficiency still helps a great deal, which water/meth injection yields.

^ what turbo you have now ????

Still the Holset H1C (older hx35). I have the h1e (older hx40) in my shed :). I got a rebuilt one and a new one for the price of one PTE turbo and about 1/2 of an fp turbo. I just want to switch over to my AWD shell and get some solid numbers out of this H1C first. . . Then I'll go from there. I wasn't anticipating the h1c being this fun. It spools so fast for how much it flows.

This is obviously a noob question. But can you meth inject on a non turbo car such as the gs. I havn't read anywhere that says anything about it so I am assuming no, or if you could you wouldn't see much gain in power. Correct?
