Question Water/ Meth injection

Are there any down sides to w/m injection? I was thinking of adding a stage 1 kit. Right now I run 20psi Boost.

Thanks

Don't waste money on Stage I, it's for low boost trucks like PowerStrokes and 6.5 GM diesels. Get the Stage II kit.

The only downside I have experienced is having to pop the hood and refill the tank when the fun runs out.

Seriously though, it's safe if you are careful to not exceed 50% meth and also not to spray at low boost. Mine kicks in at 20 psi. Set yours up to start spraying no lower than 15 psi, you will find that you pick up about 5 psi as soon as the spray starts.

Yup, as soon as the spray hits you'll see the needle jump about that much. Total gain will be closer to 10 psi on 50% meth.

Since the install of the 3200 GSpring at Rebal's place(thanks again, BTW), I have lowered both the initial spray and my full on to 16/20 on my stage 2 W/M, well before I had it at 20/22. Big difference. I gotta tell you all, I love all the chemical juices, especially the pane, but the 3200 spring is a must do 1st item before adding chemical power. The Gspring will compliment all. BTW, with what I have updated in my sig, I'm finally hitting 1100 @ the pyro. Carmyne

The controller is dash mounted and includes read-outs for boost, exhaust gas temp, and pump output for full visibility. This feature precludes the need for boost and EGT gauges. Complete kit ready to bolt-in!

How much benefit would I see running the WH1C with no intercooler?

Should I get the Stage 1 or Stage 2?

The Stage 3 is a towing setup. It's designed to keep EGT under control while getting the best water/meth "mileage". It works for playtime too, though. If your main reason for wanting water/meth is towing, then the Stage 3 is the one to buy.

For play trucks there is no need to spend the extra money for Stage 3.

Edwin, I'd still expect to see the same benefits (200 degree EGT drop and 30-40 RWHP) out of your truck. You might do even better on the HP end of it since the air on yours is hotter to begin with.

If the W/M solution is injected into the stream it would cool the hot air and reduce pressure which would cause the WG to close down some to maintain the same pressure of boost. Is this correct?

How does this make the boost 5# higher?

I can certainly see how it would add power. Could I then add more fuel?

WANT MORE MORE MORE!

More power = more boost. Also you are spraying a good amount of water in there, when it flashes to steam you get a lot more volume going through the exhaust.

You are adding fuel by putting in the meth. However, if your EGT is under control there's no reason you can't crank up the pump more to correct that little problem.

I'll prolly get hammered for this but im not terribly impressed with snow, i preferr aqua mist if i were buying a set up. Mine comes on at 15 the second stage on at 20 and cold start inj comes on at 25, quite a ride.
