A friend of mine used one of these on his Cougar for years. He'd get better
mileage, less ping, etc. If you use a water-methanol mix (windshield washer
antifreeze) then the evaporation cools the incoming charge as well.
I don't recall who made the system but it installed using a spacer plate between
the carb and the manifold. The spacer plate had a spraybar going across it to
distribute the water/methanol mix.
For us height-challenged Tiger types, it would be possible to make a system like
this by drilling across the primary part of the intake manifold flange and
installing a brass tube with some small holes drilled in it. Make sure the tube
doesn't hit the throttle plates at WOT. If you position the holes at 90 degrees
to the airflow, then the water mixture will get drawn out of the tubes in
proportion to the airflow. You need to have the water tank level slightly below
the spraybar, or else it will siphon the whole tank into the intake manifold.
