With regard to this thread on water injection, I had some

experience back

in the 60's with a device made by a company called Automotive

Performance

Inc.  Don't know much about the company itself, but the product

they sold

was call a "vapor injector".  It was a glass jar containing a
water/alchohol mix.  It had a metering valve on the lid that could

be

opened or closed to admit more or less atmospheric air.  The

outlet on the

lid went to a vacuum line as close to the base of the carb as

possible.

The pressure above the liquid in the tank was whatever vacuum was

being

pulled by the manifold, and could result in a dense fog of vapor

pulled

into the manifold and thus to the combustion chambers.  When

properly

adjusted the system seemed to be quite effective at keeping carbon

to a

minimum and also to prevent detonation.  At any rate, the system

did not

inject liquid water, which I would be pretty leery of in the hands

of a

shade tree mechanic (water being incompressible FAPP).  It only

allowed

the engine to draw water/alchohol vapor in at it's own rate,

unfortunately

more at idle (high vac) than at WOT (low vac) when it would be

more

useful.

Anyone ever hear of these things?  I think there is one in my

garage

somewhere.

Yes, J C Whitney sold them. Beenj using one for over 25 years, Virg
