I saw on ebay that a 98 and newer Mark VIII fan pulls more CFM than the older ones.  Any truth to this?  Could just be a ploy, but you never know.... (in reply to Mean Green) Post #: 33

RE: Viper Fan upgrade....worth it? - 6/21/2007 2:23:36 AM    Mean Green Posts: 3188 Joined: 6/22/2006 From: Reno, NV Status: offline Well I went around to a couple auto part stores and got the stuff I needed (a little too much I'm gonna have to go back and get a refund ). The relay I got had all the wiring done already and had very good instructions on how to wire the fan up properly and have the a/c kick the high speed on for me, while the low speed is kicked on by the engine temperature through a radiator temp probe. For anyone that is interested and good at wiring here's their instructions. I can't wait until next tues. or wed. I am gonna slap this baby in.

RE: Viper Fan upgrade....worth it? - 6/21/2007 9:44:14 AM    Kensai Posts: 1652 Joined: 12/30/2003 From: United States Status: offline Mean, if you go with the dual relay setup I would recommend to use the low speed setting for your A/C and the high speed for the temp probe.  Always use the highest cfm rating when cooling is called for by your D. Otherwise, if low speed is always on, and the temp probe is used for high speed, that should be okay. _____________________________ Black 2000 Durango 5.9 R/T Fastman 52mm ThrottleBody Fastman custom built Tranny Castrol Full Syntec OEM K&N Air filter Monroe Reflexes BFG Comp T/A''s Champion IR Truck Plugs 180 Stat Hypertech III (87 oct) Custom Made Ram Air Intake (in reply to Mean Green) Post #: 38

Here one about the CFM  (4800!! at 14 volts.) http://www.corral.net/forums/showthread.php?mode=hybrid&t=77892&highlight=electric+fan I've read on a couple site that it pulls 30 amps to run and people recommend a bigger alt.  But these are also on different cars.  Can our D's handle this power need stock?

RE: Viper Fan upgrade....worth it? - 6/22/2007 1:25:07 AM    ShadowRango Posts: 18 Joined: 5/21/2007 Status: offline I don't know why everyone is fussing over how much air the viper fan pulls in.  Think about it...depending on what year they come from, it is designed to cool a 488-505 ci V10.  It'll cool a V8 with ease.  Here's a site with viper fans for cheap: http://www.trademotion.com/partlocator/index.cfm?action=searchCatalogOEM&siteid=214096 They are p/n P5007266 _____________________________ I copied my list of mods from another site but it was too long....oh well.

RE: Viper Fan upgrade....worth it? - 6/24/2007 1:10:01 AM    Kensai Posts: 1652 Joined: 12/30/2003 From: United States Status: offline ShadowRango,       Think again.  Automakers put electric fans on cars instead of clutch fans mainly because either it is front wheel drive or cars that are not made to tow.  Let's say the V10 you mention that would be in a viper.  Ever seen a viper tow anything other than itself?  Big engines is one thing, but if they are in vehicles not design to tow or endure heavy loads, they won't even work up a sweat. As I have stated earlier in my post, have any one ever seen a truck with electric only fan straight from factory?  I haven't?  That is the real debate here, D owners that do part time towing or even full time towing are wanting some hard facts before giving up the clutch fan for a electric fan.  Otherwise, if your D is strictly for performance driving or just hauling your family around, the electric only fan should do just fine. _____________________________ Black 2000 Durango 5.9 R/T Fastman 52mm ThrottleBody Fastman custom built Tranny Castrol Full Syntec OEM K&N Air filter Monroe Reflexes BFG Comp T/A''s Champion IR Truck Plugs 180 Stat Hypertech III (87 oct) Custom Made Ram Air Intake (in reply to ShadowRango) Post #: 42

RE: Viper Fan upgrade....worth it? - 6/24/2007 11:53:01 AM    cesspool Posts: 199 Joined: 5/30/2006 Status: offline I'm more willing to take the chance on a Mark VIII fan for cost reasons.  I'll be out less than $100 versus $450+  if I go Viper. After my trip in July, I'll let everyone know the results.  Guess I'll have to take the clutch fan with me though, just in case (in reply to Kensai) Post #: 43

RE: Viper Fan upgrade....worth it? - 6/24/2007 6:10:28 PM    ShadowRango Posts: 18 Joined: 5/21/2007 Status: offline I guess it just seems odd to me that a V8, even while towing, would produce more heat than a V10 being driven hard.  Isn't the mechanical energy an engine gives off supposedly only 33% of the total energy, ie the viper's 500 hp engine gives off another 1,000hp worth of heat?  Kensai I'm not questioning what you're saying, but I've never heard anyone say that a viper fan couldn't cool their truck.  Most say that it never even has to use high speed.  _____________________________ I copied my list of mods from another site but it was too long....oh well.

RE: Viper Fan upgrade....worth it? - 6/25/2007 12:31:47 AM    Durango911 Posts: 194 Joined: 6/4/2007 Status: offline I think the viper fan is more than enough even if towing.(low t-stat/goodwater pump/fabricate a shroud)  My neighbor has a 5.9 ram with Ls1 fans and he's one of those "dedicated" people that love to tow just about everything.  He said it never overheats and he turns the fans off on the highway.  I want to put electric fans on mine but my charging system won't be good enough because of the underdrive pulleys.If you're looking for cheap fans(not $400+!), goto a junkyard and get them off a LT1/LS1.  I bought this gauge/controller for my tranny/oil cooler fan, it should work great for a project like this. http://store.summitracing.com/partdetail.asp?autofilter=1&part=CSI%2D1225&N=700+115&autoview=sku _____________________________ Prime Performance 5.9 bored .030 over,HER1828AL Cam,HPHD-MAG1-SP Heads with 110 Springs,Crane 1.6 Roller Rockers,Ported Intake,Holley 52MM Throttle Body,MSD 24/lb Injectors,MSD Ignition,Hughes Engines Re-flashed ECU,Gibson SS Headers,etc. (in reply to ShadowRango) Post #: 45
