less draw off the engine = increase in power and economy.
my stock fan didn't even lock up (which was fine all summer) and when i took off down the road with the plow on,i had to be real careful! she would have overheated real quick.
well rather than grab another stock,power hungry fan clutch to fix the problem,i had that mod planned anyway,so i went with it.
the guys say when the stock fan locks up you feel it rob power!
some estimated 20-32 hp loss at the rear wheels!
i wanted no part of that.
when my e-fans turn on,there's no way i can tell.i feel nothing.
if im curious,i'll turn them on/off to watch my volt gauge to see if swings or i'll have to pull over and walk up front so i can hear 'em.the only way i know if they're on or not.
to top it off?
even without a locking fan clutch,ditching that fan made taking off from a stop easier.felt like i lightened the truck by a good 1k lbs.no bs.
if you want to check it out sometime to see for yourself,just remove the fan and go for a drive (once you've gotten used to the engine with it on for a while.) just don't drive far from home for the test of course and put it right back on so you don't over heat the engine.
you'll feel it.
freeing up whats already there is just as good as mod's that add it.
