[Supras] mk3 cooling fans

Whoa. Don't blame me buddy! I said use the HEAVY DUTY zip ties to fasten  the 
shroud--not the standard duty.  Well, live and learn I guess.

that's  total BS... i was running a mechanical fan at atuo-x and it was 
sucking in  enough air to pull the (poorly mounted) fan shroud into the fan 
blades.. I  chucked one and a half blades, through the radiator...  doesn't 
sound  bullet proof to me!!!!   ;)

I do need a new shroud, but not  until I'm sure the damn thing won't fall off 
the crappy radiator...   It's getting into summer time, need max air flow..
