Bruce:

Awesome info.  Thanks.  What % of the intake charge have you "scrubbed" with
water?
What kinda humidy (absolute) levels did you reach?

Also, what kinda setup did you have that could support/utilize 60 psi boost?

I too am considering this as a mileage enhancement.  I would have to discuss
the potential gains for increasing the water input rate above that which is
required for stopping detonation.

I beleive Sir Harry Ricard used 30-50% of fuel volume as a norm.
(this figure may have been primarily for turbo/supercharged appl).
Lots of folks have used a windshield washer tank/motor as a
dispenser (use a check valve so low manifold vacuum doesn't
draw it out).  Also anything more than just enough to get rid of the
detonation is a waste of fluid.  No real gains past that.  Might
be more info in archives, about this.  ie injector types methods.

Sir Harry Ricardo has covered it in more detail than I mentioned
his book "the High Speed Internal Combustion Engine", last
revision 1965,  is the best source of this, that I know of.
  I've seen no gain in MPG, and slight gains in HP in naturally
aspirated engines.  Now when ya talk turbos, I've had intakes
hot enough to cook paint off of (60 PSI, of boost), and it makes
a HUGE Increase in HP, when ya have the water right.  And the
30-50% figures hold true for diesel, and gas in my experiences.
  I've also tried a humidifier set up where a percentage of the
intake charge air was drawn from above a water trap type
device.
