IS any one using this for their turbos or superchargers to prevent detination a high boost, my tuner runs this on his twin turbo 585 cubic inch big block chevy at 1680 RWH on 91 octane pumped gas with no problems. This set up allows him to run 7.8 at 178 in the quarter. I'm looking at buying it, if anyone is intrested I can problably get us all a deal as this system is made locally, works automaticlly and uses windshield washer fluid (cheap) gives you complete data logging and is activated on injector duty cycle.
Let me know if you are intrested as I might by buying this week.
PM Me.

 

lots of people use water injection. go to my350z.com and look around or do a search...

 

I just ordered the Snow Performance stage 2 kit

 

I just order my FJO System, it actually does more than I originally thought it will data log usage ect. it pulses the spray just like a fuel injector would while mantaining pump pressure, they say this prevents burble at lower RPM and is run by it own ECU. Will say how its works. They also have a wideband O2 gauge that uses two O2 sensor, one for each bank, the display always displays the leanest bank of the two, it is kind of a neat gauge set up, I'm getting one of these also to replace my AEM wideband.

 

Got a link on it ?

I have a coolingmist kit on my car. It does not give much for power but does help reduce the risks here in the 115 degree summers.

 

Water injection is great. I built my own WI kit back about 6 years ago and it dramatically reduced detonation. Generally one should inject the minimum amount of water necessary to raise the effective octane to a safe level (after all, vaporized liquids will displace air). I recommend running 100% water rather than using methanol as a band-aid fuel solution. If you're running too lean and need more fuel, fix it the right way.

 

Is anybody tuning cars on dyno after install? My guy said with out tuning I would loose power do to lowered EGT's. After tune I could gain some power and run safer.

 

Assuming you're not currently running in some fail-safe mode due to excessive knock, yes, simply adding WI and not changing anything else will generally decrease your power output. However you will be running much more smoothly and safely (assuming you don't inject way too much). After some tuning you can produce more power than before and safer than without WI, but you can also tune it to the point where you're just as on the edge as you were initially. When water runs out, boom boom.

 

The Snow Pereformance system has a fail safe controler Also . It will open the BOV if the W/M injection flow drops to low .

 

Sounds like a good feature.

However I've yet to see a perfect WI system. They all attempt to regulate flow by regulating upstream pressure from the nozzle (by varying pump voltage or pulsing a valve). The downside is that to get a decent range of flow adjustability, your nozzle needs to flow at very low pressures, so you're forced to use relatively course nozzles, and pump output is dicey and varies quite a bit at low effective voltage. If you use an atomizing fogging nozzle that doesn't crack until 30+ psi, even with a 100 psi pump you only have a 1x to 1.8x range of adjustability, which won't even handle the change in airflow over the RPM range. If there was just a high speed injector (like a fuel injector) that was compatible with water, life would be easy.
