Snow Performance GM MAF water injection kit.

[Kmiller86]

Hi, this spring I am going to be adding water/alky injection to my car. I have been looking at many different kits that are out there. I dont want an on/off type of set-up. I want a progressive set-up so everything comes on smoothly. I have the gm-maft in blow-thru set-up and wanted to know if this would work well or if anybody has anny experience with it? I also have dsmlink. would this still be able to work? Any help would be appreciated.
Thanks.

It should work pretty good with your setup, I say go for it

I am wondering the same thing, if the injector needs to be after the GM maft. My main concern is that the water might damage the MAF.

The Snow unit is a nice kit. Cooling mist also makes a progressive controller for thier kit.

Most of the research I have done people have put the injector after the MAF-T.

You guys don't understand click the link he doesn't want to know if the injection kit will conflict with his GM setup, he wants to know if the setup which is designed to read a GM MAF signal and inject according to the reading it gets works well for our cars seeing how the kit is designed more for like mustangs and cars that se the GM MAF stock. To the original poster I was lookin at this kit as well as I want a progressive kit also. I think that no matter what the GM MAF works the same no matter what car it's on and should work great.

As stated, the Snow kit will work fine. And I would put the injector after the MAF-T.

I was also giving him another option for a controller that works off boost pressure instead of a signal from the MAF-T. I'm a bigger fan of using a boost signal as the source for controlling my future WI kit and have been looking at the CoolingMist setup. Thier controller has a variable lo/high settings with 10 different "curves" for injection, plus the ability to make your own "curve" through a laptop. Plus you can log your WI using the TPS as a "normalizer" to overlay it with a DSMLink log inside Excell to see how things are working together.

I guess I'm just a log pullin' SOB.

Just letting you know that the Vari-Cool controller is by far the best, most advanced, and most tuner friendly controller available. This is why we now offer the controller as well.

I just got water injection from you guys and
i have dsmlink. Would dsmlink be a good controling unit for WI by using nitros control...

i wouldn't worry about the water damaging your maf as much as the incorrect airflow damaging your engine. having water go through the gm maf makes it go CRAZY and all its readings are WAY off, so youll get ultra rich or ultra lean combustions...

who cares if it damages your gm maf, thats only 130 bucks. compair that to a new longblock

works well for our cars seeing how the kit is designed more for like mustangs and cars that se the GM MAF stock.

so now gm makes mustangs? jk, I don't care about either cars so it doesn't matter.

This Snow product should work great. The GM maf sensor, though "translated" by the maft, will still consitantly output the certain signal for a certain airflow. This is why the translator can translate the signal and deliver it to the ecu in a "language" or hertz count it can understand...

A problem w/ boost based water injection controllers is that water injection works best when water is used at a quantity of 15-25% of the total fuel being used at any given open loop session. Now, metering out water based on boost alone cannot possibly maintain a 15-25% water delivery WRT fuel, as there are intake air temp changes from the outside air and from the turbo passing through its efficiency bands. As well, the engine volumetric efficiency changes plus and negative at different rpm levels. Referencing just boost won't yield a consistant water/fuel mixture. However, you can indirectly meter the water to correspond to fuel flow if you directly meter it w/ the mass airflow (not volume airflow), as most of us try to keep a relatively consistant a/f ratio when running WOT.

But nevertheless, I've had great success w/ a boost reference switch/meter in my kits. I think that such a level of precise water/fuel mixture is more beneficial for track-limited setups. As long as you can bring on the water flow in such a way that it does not cause a noticable bog then a boost reference meter is probably best because it mostlikely is more affordable.

HA HA HA yeah I was def thinkin about camaro's but it's ok I opened myseld up for that

Another option is the progressive kit from Devils Own. Two fast guys from my town run their setup and are very happy with it.

i have been looking att hem for a while because they have cheap progressive kits. i bet he would do a group buy on kits along with the 3-bar map sensors, not the punny 2-bar....
actually, were would you go about mounting a map sensor on our cars?

Both of the guys here in town, 11 second spirit R/t and the 280zxt that traps 127, run speed density. They just tapped into the MAP sensor they use for the ecu. The 280Z uses a 3 bar gm map mounted to the engine side of the firewall.
