Water/meth injection has been a thing for a while. Corrosion is a huge issue so thats why it hasn't been popular for daily drivers. This just sounds troublesome for the average guy to try to maintain. Snow Performance has been doing this for years

I hear this thing may be coming to Canada...

  then why is he choosing BEER ov'r METH...... ..does Canuck have a NEW IMPROVED RECIPE

Scottish ALE with 50% added MALT from ISLAY.....that should slay the Sassenachs....

Heh.

hmmmm........... a large container of water in stored in a car during a Canadian winter. What could possibly go wrong?

It's usually mixed with methanol.

Just chip it. That'll get your extra 68 horsepower, no dicking around with water injection. They can keep that wing, too. Blugh.

Yep.  And Snow Performance has the shittiest components I have ever seen.  I have had their fail safe module fail.  So much for being fail safe.  And looking at their design it is not inherently fail safe from a controls perspective. Methanol kills the pumps eventually too.  Had a pump fail on me too.  The other problem with 99% of the kits out there is they duty cycle the pump to control delivery, but it is very inconsistent from run to run.  As well, you cannot get even distribution to each cylinder if you are just spraying it into the intake tract.

The only way I would do water/methanol injection is if it's an Aquamist kit which has injectors that you duty cycle with a constant running pump to guarantee consistent delivery.  However, I would still want to plumb it into the intake manifold with individual feeds to each cylinder.

Honestly, I'd rather pay for more octane than screwing around with water/methanol injection.  Race fuel is cheaper than engines when your water/methanol system fails.

One nice thing with water/methanol injection is you never have to worry about carbon build up issues that is common with so many DI engines.

Didn't the Saab 99 Turbo have water injection (in the late '70s)?

In that case, you want E85 and be done with it.  HUUUGE gains.  And way, way cheaper than race fuel.

Alcohol Injections Systems make a really nice kit too.  http://www.alcoholinjectionsystems.com/index.php?cPath=37

I totally agree with you, fuel over water.....if we had E85 you could really tune the crap out of cars.

Excellent! It's the first thing that came to mind!

Just like the first line of the article says...

Problem is, we don't have a single E85 pump in Alberta.  If it was more commonly available, I would have done it in a heartbeat.  The Haltech Platinum Pro in my car can take a flex fuel sensor input and compensation tables can be setup.

I saw the Alcohol Injection kits.  The base premise is the same as Snow's kits.  You can never get consistent delivery nor good response when you duty cycle the pump to change delivery rates.  Hence why Aquamist is the best and is a lot more $$$ to do.

Agreed 100%, APR has a chip for the 2.0T in the A4, if you run E85, with no other changes, bumps to 280 hp/367 tq at the  wheels.
Unfortunately only for US flex fuel A4's, but it shows the amount of boost and fuel delivery that can be dialed in on E85.

Thats why I do not get all the stickers and badges on vehicles with the flex fuel crap....yeah, in the states, maybe, I have never heard or have seen an E85 pump in Alberta, BC, Sask or Manitoba.

Probably:
1) To let you know that you could refuel with E85 if you happen to visit where it is available
2) I believe OEMs get CAFE credits for selling flexfuel vehicles in the US, I'm not sure if they get any credit for Export sales.
