[6pack] Damper/fan discussion

[michael lunsford]

I have been running Rick Patton's fan eliminator kit (along with his TBI) for
about 3 years without any problems.  The kit was easy to install and I think I
got a little more power by eliminating the mechanical fan.  I'm using an
electric pusher fan which is a little smaller in diameter than I would like
(sorry I don't recall the diameter-same problem as Vance) and it has worked
fine.  I have a 9.8 to 1 compression ratio GP2 cam and other stuff that
probably increase the motor heat.  Since I'm in Florida where it gets ugly in
the summer heat wise I doubt that the minimal reduction in air flow due to the
placement of the fan will be an issue.  I used the thermostat provided with
the electric fan and just placed it externally at  the bottom of the radiator.
Once I got the right temperature dialed in to the rheostat it has worked
without any problems.  I have found that you can hear the fan running when you
are stopped and when you are moving
 it is usually irrelevant.   If I was going to re-do the wiring for the fan I
would probably put an off on switch into the circuit just for a little extra
insurance.  I also put the fan circuit on a relay with the electric supply
taken directly off of the output from the alternator (70 amp Mazda) to ensure
that the wires weren't overloaded.  Works for me.
