Ditch the clutch fan????

[smokenhalfton]

any every got rid of the clutch fan and installed an electric. thinking about it say it on the Powerblock today. my truck never runs hot anyways, got a electric fan out of a car

I installed a clutchless flex fan its a lot cheaper and makes more power that an electric fan does.

An electric fan draws amps and that draws horse from the crank.

A flex fan is 10lbs lighter so it always makes more power.

Just my .02

were did you get on

[dereku]

crap I knew you were gonna ask I'll look

1999-2003 FORD Superduty Powerstroke 7.3L Radiator Coolant Flex Fan System here is a link. Its a decent price too. O wait you have an OBS maybe it will work tho. All the bolt holes are slotted I think.

how does it draw power from the crank the alt is spinning no matter what putting a fan back on will take more power to run then a elec fan. Also be careful with that flex fan i have seen a lot of them fly apart and cause a lot of damage.

the alterantor at low or no load does not require much energy to run, but if you start drawing power, the alternator requires more and more power input to raise the output.......kinda like a portable generator, when you plug in a heavy load, you can hear the motor bog down.......

but it is still going to take less power then a flex fan to run this has been proven many years ago

I know they sell the kits for Dodge diesels so if they are used with a cummins they should be able to cool good enough for the 7.3. I would prefer electric because then it is on only when it needs to cool. I put an electric fan on my street rod and it works great and it was supposed to free up about 15hp at max rpms. I think the issue would be finding one that can flow comparable cfm as the clutch driven fans....

Nope do the math with energy loads. So many amps rob so much horse power when they are on. Not to mention a flex fan is $50 from summit and an electric fan is 500. The cheap flex fans blow apart all the time. The flex a lite ones wont, they are designed to spin upto 10,000 rpms.
