I Googled "intercooler spray bars" and saw types that were tubes surrounding
the intake opening with little jets all around.  I also saw one that was
simply a large jet in the air stream spraying towards the center of the
radiator.  I would guess that there is no real answer yet, or that either
works.  I also saw pump pressures from windshield washer pressures(?) to
40psi and flows up to 6 liters/hr., I believe.  our application is way
simpler than in these race cars.  seems easier to try out than, say, adding
a turbo!
