turbopath Posted November 2, 2006 Share Posted November 2, 2006 (edited) ya, if you haven't gotten off yer lazy butt and ripped out the stock fan...do it already! It's amazing. I now a have a really quiet ride that doesn't struggle to get up the hill to my house anymore. It's not some huge hp gain, it just doesn't struggle as much with hills etc. I'm in the middle of fiberglassing a shroud for a pair of fans to throw on there. Even sitting in traffic etc the truck hasn't come close to going past the 1/2 mark on the guage with no fans at all....

MichiganAve Posted November 2, 2006 Share Posted November 2, 2006 What did you get and where? Did it bolt up without having to fabricate anything? Link to comment Share on other sites More sharing options...
vengeful Posted November 2, 2006 Share Posted November 2, 2006 Even sitting in traffic etc the truck hasn't come close to going past the 1/2 mark on the guage with no fans at all.... Hah...try that in July. Link to comment Share on other sites More sharing options...
turbopath Posted November 2, 2006 Author Share Posted November 2, 2006 well, you could get some cheap through radiator fan mounts and not fabricate anything. I'm making a fiberglass shroud to hold my fans though....for when july comes again. haha. Link to comment Share on other sites More sharing options...
nissandoms47 Posted November 2, 2006 Share Posted November 2, 2006 i need to do this. sense my radiator support is all messed up. the the shroud is out of line with the engine fan so it scrapes and what not. lol. Link to comment Share on other sites More sharing options...
MichiganAve Posted November 2, 2006 Share Posted November 2, 2006 Hmmm, just read an article that points out some issues with E-fans and suggests that their HP gain is very minimal: http://www.aaroncake.net/rx-7/efanmyth.htm Link to comment Share on other sites More sharing options...
vengeful Posted November 2, 2006 Share Posted November 2, 2006 The reason to do an e-fan is not for the HP gain. An e-fan with the same CFM rating as a clutch fan will cool more effectively, because the engine does not have to create energy and thus heat, to drive the fan.

turbopath Posted November 2, 2006 Author Share Posted November 2, 2006 That guy isn't completely correct...my fan only draws 20 amps and the only fan I can think of that draws 60 is the 4000 cfm taurus fan. And he isn't considering the loss of a 10lbs of weight from the rotating mass of the engine. People bash underdrive pullies too, but I picked up 8hp to the wheels with my aluminum lightweight (and smaller) crank pulley. I can guarantee you the engine wasn't making any more hp, I was just losing less of it. Different car though. Link to comment Share on other sites More sharing options...
vengeful Posted November 2, 2006 Share Posted November 2, 2006 I have a fan out of a big Volvo Truck.. Y'know, one of these The dimensions of its shroud match my radiator perfectly. The diameter of the fan is 1" larger than my clutch fan. It pulls some 4,500 CFM, and only draws 30A. I haven't installed it yet, because it was a recall unit because the relay box on the unit itself is prone to fire. All I have to do is cut the wires coming out of the relay box, and splice in some nice heavy gauge wire, and then install it. I'll post some pictures when I do it. I got it for free through a contact of mine at Volvo Trucks here at my job. All the rest of the recalled units were destroyed. They retail for close to $1000.

max_stryker Posted November 2, 2006 Share Posted November 2, 2006 i snagged my dual e-fans out of a 92 maxima, its not mounted because it is a VERY tight squeeze, actually had to trim the shroud wher ei bent it to make it fit. however my fan clutch never came off....its stuck...and prob wont ever come off...but i love my efans. wired them to a switch the dash for a temp but will go through a constant later so they turn on by themselves when i turn the truck on Link to comment Share on other sites More sharing options...
QuismO Posted November 3, 2006 Share Posted November 3, 2006 i'd totally do this if it was a direct bolt on (i'm not good at fabbing things up). so do you totally remove the clutch fan and its components? what about the belt that drives the fan? turbo, do you have the t-stat/relay setup? or just a switch? how would you hook a lead up to the t-stat? or is there already a sensor of some sort that triggers the fan?

turbopath Posted November 3, 2006 Author Share Posted November 3, 2006 you rip it all out. You have to leave the belt. My fan clutch took some persuasion to remove. You could leave the shroud and just stick a fan in the middle there. I bought a wiring kit that came with the sensors and everything for the fans.

I'd absolutely love to get my hands on something like that for our Frankenvan... As it is, I am going to try to squeeze 2 Taurus fans in there. Climbing up ultra twisty 15% grades at 10 mph while hauling our trailer and toys on 100+ degree days requires a wee bit more airflow than stock! I have a Taurus fan in my '88. The main benefit I've found is fuel economy. It takes a lot of energy to spin a fan. If you don't need to, why do it? Back to back 1000 mile round trips showed well over 1 mpg improvement. I have it wired where the fan is always off at highway speeds, even if the A/C is on. Link to comment Share on other sites More sharing options...
XPLORx4 Posted November 7, 2006 Share Posted November 7, 2006 FWIW, last summer I installed a Flex-a-lite #295 27" electric fan in my Pathy. At first, I was dubious about its cooling ability, but after enduring the summer, it proved itself to be worthy. One thing I did learn, courtesy of my Scan-Gauge, is that "normal" coolant temperature has a very wide range, from 172°F to 225°F. The temp gauge needle starts to move up from its normal 1/2-way position at around 230°F. I don't really know how much fuel economy I gained, but one thing that's nice is that in the summertime, you can get cold AC blowing all the time, even at idle.
