water injection questions

[Robert Yorke]

Water Injection Systems are still available from Spearco Performance
Products, Inc., 14664 Titus Street, Panorama City, CA 91402.  Their Phone
number is:

                (818)901-7851
                FAX: (818)785-4362

The part number for their complete system is P.N 980 Turbo Water Injection
System; Price listed is $146.00 (This may have changed by now)

This unit is controlled by an adjustable "O.E" quality pressure switch, for
turbo engine use, so some other means of turning it on would have to be used
on non-turbo cars.  A 4-gallon aluminum reservoir is shown on the catalog page.

A lot of people mix Methanol (50/50) with the water.  Water alone will act
to slow the combustion process; equivalent to raising the Octane rating (All
Octane rating is, is a gauge of how fast a particular gasoline fuel burns in
a combustion chamber).  The ignition timing can then be CAREFULLY advanced
to take advantage of this.  With Methanol, you have a more pronounced effect
(The equivalent Octane rating for Methanol is 105).

If anybody tries this, be extremely careful.  If you forget to keep the tank
filled and you don't have sophisticated controls to either tell you of this
or to shut the advance curve down to stock when there is no injection taking
place, you will cause yourself a problem....
