[Supras] mk3 cooling fans

[Aaron Hansen]

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
