Water/Meth injection

Jordo!

Dial everything else in first. Honestly, if everything is tuned to the limit, there may be no more power to be made.

Before I had an intercooler on my supercharged 2ZZ, I picked up 15 whp with W/M direct port injection -- but I was overdriving the blower and had no IC, so I desperately needed some cooling at that point! Moroever, the ECU was pulling some timing. The W/M fixed all of that.

I had a nice coolingmist progressive controller with a W/M injector ported into each intake runner -- worked great!

However, after I had an A2W IC installed, the W/M made absolutely NO DIFFERENCE in power. We experimented for an hour with the tune on the dyno, and it just diidn't matter -- timing was optimal, and adding timing yielded no extra torque. I would have uninstalled it and sold it off a that point, but it was too much of a PITA, so I left it on as a safety measure as it wasn't hurting anything

If you were non-intercooled, I'd be more of an advocate for it. If you are intercooled, you probably won't need it.

In fact, I'd say the time and money would be better spent upgrading your IC components -- is it A2A or A2W (I recommend the latter, although the former can work well too)? If A2W, you could upgrade the pump or add another heat exchanger to further cool things down -- or as one person noted, you can get a larger reservior and pack it with ice for track days!

Also, what kind of track are we talking about? Road course, drag strip, autocross???
