Re: Homemade Water inject-->MISTER for IC

["Leigh Anderson" <leigha@teleport.com>]

This thread (s-cars list) reminds of another kind of related idea...
Simplest idea of all re water use, is to put a boost-actuated simple garden
mister in front of the IC for extra cooling on hot track days. Use ww fluid
reservoir for water supply.

Plus'es:  simple, inexpensive, prevents HP degradation in higher ambient
temps, (reduces detonation conditions?), zero risk if it malfunctions
Con's: doesn't have as big an effect on detonation, intended really only for
track days in summer

I haven't done it yet, and will be looking for parts soon, but a mister will
be on my UrS4 before summer track events.  Also plan on installing the dual
temp probe/gauge before+after the IC, to monitor the IC performance.  Has
anyone already measured mister effectiveness?

Any IC_mister parts/source/etc BTDT?

QUATTROS UBER ALLES!
