water injection

[dwalter2@wi.rr.com (Donald Walter)]

Back in my air cooled days I ran had both a spearco and garrett H2O systems.
I had a 5 gallon tank in the back of my Karmin Ghia.  The garrett used a
fuel pump for the water pressure.  It also has an electronic unit that
controled the flow and rpms when it kicked in.  By the way I was runnning
11.5 to 1 on 87 octane.  I still have parts of them yet, not everything.  I
used the pump in a car that the fuel pump died in.   I knew a guy that used
it in his 440 six pack roadrunner.

Later,
Don

Hey, I think I'm about to blaze some new trails here, but I figure I'll ask
anyway. Does anyone on the list have any experience with water injection?
I'm rethinking my plans for a fuel cell holding racing gasoline for use when
I activate my nitrous system.

There's a lot of redundant plumbing and electrical controls that I'd have to
rig. -more weight and more stuff to go wrong. I'm thinking that a well
implemented water injection system would do the trick just fine. I figure
that I could activate in two situations: a) via whatever signal triggers the
nitrous, and b) whenever knock is detected.

I could mount the water tank pretty much where ever I'd like. I figure I'd
put it somewhere around the battery (in the back) with a couple of small
windshield washer pumps run inline to keep the pressure and flow up. The
minor plumbing challenge would be rigging a distribution block and lines to
each throttlebody. And, of course, I'll have to find some spray nozzles with
a nice atomization pattern and the correct flow.

Babble... babble... I'm on Spring Break!!!! :^)
