water/methanol injection

You need about 30% more fuel. At speed it's more like 26% or so. Stoich on E85 is like 9.8:1.

Timing depends on the car and boost/compression. On the Evo I run around 2º more at peak boost and around 5º more at redline, but I also run about 5 psi more boost.

Also, stock Evo injectors are 550s if they will work on the 240. Not sure. But they are cheap.

The injectors the 240 uses are sidefeed ,high z,I haver been told that stock STI injectors are 480 and they are sidefeed so they might be the ticket . Are the evo injectors sidefeed?

Don't think so. They are also low z.

Ricky, I set up mine and Pat's turbo cars with water injection but they were not boost-tuned for it, it was strictly a safety measure.

I sourced parts from coolingmist.com over in Atlanta, Napa, Lowes Racing and an RV supply place and made up a couple of inexpensive basic systems that are triggerred by Hobbs (hour-meter) switches at a set psi with secondary pressure switches triggering a "flow" light so you know that the system is active, which is also recorded on the datalogger.

Not "fancy" and not really a power adding setup but it helped keep together 180,000+ mile stock motors at more than double the original hp. To tune for power you've got to step-up the reliability of the system with some sort of fail-safe.

They dont _have _ to be high z , I can set MS up for low z but I'd prefer to stick with what I have .

You can wire in resistors to make them low z. Again, you can search turbobricks for information on it. They might even have some to sell you for absurdly low prices.

Map switching would be cool though, never have to worry about where to fill up!
