[Supras] mk3 cooling fans

[Chris Smyczek]

You do not need massive amounts of air to properly cool, you do however need
air channeled properly to make the exchange. One square foot cross sectional
is adequate at the grille. Your shrouds must be in place, under engine
plastic specifically. Stay away from fans which move lesser amounts of air
than the stock blade clutched. Why look for power from your cooling system
when you are generating increasing amounts of heat?

The car should have plenty of air flowing across the radiator at 100mph+
unless the fan itself is a restriction to airflow.

I thought there would be a problem as well when making the switch to dual
electrics.  I live
in FL and no problems yet unless I'm thrashing around at 100mph plus in
which
case the temp
needle just creeps up a teensy weeny bit higher.  On very very hot days I
might
not take it up
that high and loaf around to keep things on the safe side.  I had my
trepidations but no longer,
electric fans is definately an improvement where every second
counts.....doesn't
seem to tax the
alternator either.  I have 3 stereo amps plus all the electronic doodads one
could ever imagine and
never had an issue.

I don't know if I'd call that BS. Sounds more like you needed to have the
shroud mounted properly. ;)

If the stock shroud, fan, and clutch are in proper working order you should
never see this. Even if your shroud was mounted correctly (and free of
cracking damage) this would be an edge case at best and not the rule.

I've never seen dyno sheets showing a significant gain of power just by
switching to electric (doesn't mean it's not possible), but I have seen dyno
sheets showing no significant gains (no I don't have them myself).

Heh heh, this topic comes up every Spring though. Must be time to change my
heatent [ (c) Jeff Mohler ] again. :P
