Re: Water Injection for 6L XJ engine?
 

100% Alcohol will require doubling the size of carburator jet size,
etc. for approx. four times the flow rate. True that water injection
will increase the 'octane number' but you will NEED that water
injection since alcohol (volumetrically) burns at about 300 degrees
hotter than normal gasoline because alcohol 'carries' its own oxygen. I
used to burn methanol in a sprint car; and, can tell you that straight
alcohol will not be a 'benign' fuel to use as it will require you to
regularly rip down and clean out all the intake/exhaust passages
(carbon, etc.). Engine wear will be quite accelerated and you will need
to continually 'perfect tune' the engine. The down side with alcohol
is that if you have a fire in daylight, you cant see the burning
alcohol flames and will only know when something is wrong when the
paint starts to bubble and the rubber/plastic stuff starts to 'drip'.


Wow 26 mpg with an XJ !!! Ive busted my tail trying to get 22 and
cant get over that 'hump'. Good for ya !!! Maybe I've lost the
'touch'

20MPG is typical to good for an XJ, depending on the details. Mike, I
don't know what your special circumstances are, but they give uncommonly
good results. Hmm, maybe you have Keebler elves working on your
vehicles.

Re: Water Injection for 6L XJ engine?
 

Isn't all Kalifornia Gas now about that mix? All the brands I've
tried smell like it, and all drop mileage by about 10% on the
freeway. Maybe I should inject some water.

Never heard of gas/water helping an engine unless the engine is
turbo-charged. e.g. the old Oldsmobile engine that had a water
injection system, where if I recall, the alcohol was mostly
just for antifreeze.
