Water/meth injection pros and cons?

[tylerb05]

Exactly what the title says

Been looking at them just wondering what y'all guys know or have experienced with this.

Might invest in one down the road

I personally am more in favor of making the truck operate more efficient with an intercooler system upgrade and or a turbo upgrade. Rather than adding meth.

I can post links for intercoolers if you want.

Pros: Lowered EGT's with higher water levels. Higher HP levels with higher Meth levels.

Cons: Hydrolock of the motors, should the system not be shut down correctly, or have a failure somewhere along the way.

What are you intending to get out of a Water/Meth kit?

If you are looking for more power for the cost of some of these systems (plus fluids), I would look at the following options in order of how I would install:

1) Upgraded turbo - lower EGT and higher power levels.
2) Ported Intake Manifold - this is a huge restriction in stock form for airflow through the motor.
3) Intercooler - next step in lowering EGTs.

Not to suggest abandoning water/meth as an option, but its not something I feel is worth it on these trucks. There are better options out there, depending on what you are trying to get out of a system, with lower risk and won't require that supply of fluids.

been running snow's kit for years and works great.

Ya I've heard of the hydro locking the engine that why I was asking . I might just have to get a upgrade of a turbo later on.

I'm looking for high hp while lowering the egts . And what do you mean if the system
Isn't shut down the right way?

Strokin6 what stage you running have you had any problems?

I think he's referring to if the meth injection system isn't shut down properly prior to motor shutdown, then it will fill the cylinders with water causing hydrolock. Correct me if I'm wrong.

^ yes ...........

I've been running the Snow stage 2 for 4 years.

You don't want to shut your motor down right after running W/M, any moisture that sits in the motor, has a potential to cause rust deposits. This is why it's a good idea to run the motor at least 5 minutes prior to shutting down.


Hydro-locking is caused by having your tank higher than the injectors in the elbow when you don't use a check valve. Or if for some reason the pump doesn't shut off and fills the cylinders with W/M.

With the Snow stage 2 kit, you have a LED light that turns on when the pump is running, if you were to shut the motor off and that light is on, then you better check the pump, because its probably pumping in the W/M.

I have a Coolingmist setup and have nothing but pros no cons with it, better performance, lower egt's, etc.... The whole hydro locking thing while yes it could happen in extreme situations is few and far between with todays systems, also for those worried about things like rust in the cylinders from and left over residue you can add water soluable cutting oil to your tank to help stop things like that. 90% of the time I run -20 washer fluid then if I'm actually going to be racing or anything like I keep a few gallons of boost juice around
