Why not use water/alc/meth injection?

svxsubaru1 · #1 01-31-2006, 03:26 PM

Since the SVX has a 10.1 to 1 comp ratio it seems like using some sort of injection system using water/alc/meth/propane would be greatly benifical in letting us run alot more boost while still using the stock internals. I know you still need to be able to mess with fuel supply and boost to aculy get any benifits, but it seems like emanage could let us adjust enough to get some pretty large benifits from it. Any opinons?

Here are some links on genral information on it, and evn DYI kit for under $200.

I've been suggesting this for the last couple years, and back when I was planning to build a turbo EG33, I was planning on using water injection instead of an IC. For mild boost levels, it could easily work in place of an IC. Seems that the most common arguments against it are, "what if it breaks", or "what if I forget to put water in", or "its a hassle to always have to add water".

I think it could do more than that, theres STi putting out 500 WHP on pump 93 with meth injection. I bet we could get the eg33 to handle +10 PSI on pump if we could get the fuel (injectors/pump)for it with a safe tune with alc/water mix.

I have been running the SMC kit on my WRX for almost year now. I picked up 40whp and 60tq from being able to push the boost up and pulling out some fuel. If your crazy like me you may even try adding Nitro to the mix.

If you are going to get one I would suggest getting one with a progressive MAP based controller.

Yep, that's exactly what I would expect... A little less fuel to get more to the optimum power afr and better detonation control. Makes me want to reconsider spending the money to turbo my EG33. :-)

I have a friend with a pickup thats about 10:1 with blower and water injection thing is a 2.25ton weapon. Don't forget the fuel economy benifits of injecting water
