Elec. fan worth the $ for HP gains?

[jaymac]

There's a flex-a-lite fan for $100 around here. Is a swap worth the HP gain?
I have no overheating problems what-so-ever, so in terms of pure performance gain, could my $100 be spent better elsewhere?
Thanks,
Jeremy

when i put mine on i did not notice a difference, maybe worth five hp. But 100 bucks does seem like a good deal, i would do it

I also use a volvo radiator fan, the power gain youll feel is from a cooler engine moreso than less rotational mass. Those volvo fans are monsterous.

You can pick up a dual 11" Ramcharger fan for $89 shippied. Add to that about $10-$20 in wiring supplies, and you have a awesome setup that won't break the bank.

Here's the fan without wiring harness..

If you don't want to make your own harness, you can buy it for $139 with a harness/switch setup here...

IMO, it's money well spent.

One thing you should consider is whether you are running a stock charging system, or a upgraded 3G setup.

i got mine for free.... from a friend, but i kept frying switches (i just wired it to an on/off switch) so until i wire it correctly it's out, i ran the time in my sig with it, and i'm running tonight, so we'll see if there's a difference, i doubt it

yeah, running a stock alternator w/ u/d's, so that was def. a concern of mine...
And I DO need d/r's but I want something I can take advantage of every day, not just a few times during the summer. Plus, if I shave another .5 off my time, then I'll need a custom-built rollcage

An electric fan draws approximately 1/2 HP worth of electrical power. Compare that to the 5-12 HP for a stock metal fan.

You need a relay. A bosch 75a relay should be ideal. Have your switch turn the relay on, then the relay turns your fan on. Use 10G wiring at minimum and use a fuseable link in between the + battery terminal and the + terminal on the relay. The fuseable link needs to be 2 sizes less than the wire its pretecting. I use 10G wires so my fuseable link is 14G.

jaymac, stay away from a flex a lit fan. Buy a cheap used Ford fan or any stock electric fan that will fit.

so then an electric fan is only great for cooling performance??? i was also considering this but i dont want to buy an 3g alternator too...
