I've been thinking about getting an electric fan and came across this company. I've never heard of them before and was wondering if yall knew anything about them. This is the one I was looking at getting: http://store.summitracing.com/partdetail.a...15&autoview=sku |

Hmm I cant say I have heard of them. But then again I am no expert in the E-Fan area.
One thing I noticed though is that one you linked is a 16" - Im not sure if that will even fit. I think most guys use 12" ones. Something worth looking into.... I was going to put E-Fans in my Blazer this spring/summer and was planning on ordering from Synergy. They are much cheaper than the one you linked. This one is probablly what I will go with. Synergy also has a 10" and a 14" too if you wanted bigger. |

I'm almost positive you can fit a 16" e-fan, you could probably fit even bigger but not many companies make anything bigger than 16", instead you move into getting dual fans. And people don't seem to have problems fitting dual fans because many swap the clutch fan out for a nice Dual LS1 fan setup.

I like it, puts out 3000 CFM and at only 10 amps if I am reading the Summit page correctly. That is awesome, well worth the money.

I'm lost a little. I called flex-a-lite the leader in fans, they said they did not have a fan yet for a 2003 4.3L with air. Flex asked if it got to 100* here, and I said yes. A model dual 480 ( I think ) will be out in spring of 08', but the single blade unit they have now would not cool enough. So I was wondering what people are using in the South West and out West here.

If it can be used with the original shroud, it shouldn't be too bad... The Zirgo, I mean... Heck, you could always trim the fan shroud to clear the 16" if the orginal hole isn't large enough, lol.
Then fab up some brackets and you're good to go. Though, you'll need to wire in a temperature switch... Unless you want to turn your fan on and off manually... Which means no letting it run when you're not at it, lol. |

Are you thinking of running two 16" fans? or just one?

If you go to two 16" fans, I don't know if it'll fit...
At the very least, you'll have to make a new shroud, instead of modding the factory one... That's assuming the 16" works good... Not sure what the clutch fan pulls as far as air flow is concerned... |

I'd worry about it pulling enough, and in the event of it burning out, you'd be without a fan. With the dual fans, you'll have the redundancy of the second fan. Just a thought (or two, i guess :lol: )

You have a good point. I figured I'd get one of these and a nice 180 T-Stat to go along with it. Do you think I would have any heat issues w/ the T-Stat and e-Fan on those 100* days down here in S.Car? |

Rig up each fan to kick in at a different temperature, or the second one to kick on when the A/C is turned on...
That's how it worked in my old Lumina... One fan kicked in at one temp, and the other fan barely ever kicked in at all, except for when the A/C was on... |

Reports have the stock clutch fan pulling in excess of 4500 cfm. If you live in a warm climate you need to pull at least 3500-4500 cfm minimum.
That single 16" fan will not come close to cooling a v-6. If you had a 4cyl it might work. I would go with no less than twin 12" fans in a good shroud. If you want aftermarket look to the Flex-a-lite 210. Personally I think the LS1 fans are hard to beat. |

Well dang. There goes that bright idea. But I guess if I'm gonna do something I better do it right the first time. Quick questions, can those LS1 fans be found in a V6 Camaro/Firebirde because my friend has an '02 V6 Firebird with dual electric fans or are those different?

Hell I had one of those el cheapo fans from advanced on my 94 with the 4.3 cpi and it cooled it just fine here where it gets up to 100 degrees I also had a hyper tech thermo master chip, 180 stat and water wetter. Never got over 210 degrees

I wonder how well the W-Body e-fans would work for application?
Either the ones from the V6 or the new V8 versions... I know with my old Lumina Z34, in 80 degree weather, when I turned on my fans I could bring the engine temperature from normal operating temperature to 1/4 of the way up the gauge... It had the same #'s as my Blazer does... |

Those should work. Mine are out of a '98 Camaro with a V-8. The newer ones are probably better since I think those have the blow through rubber doors. Take a look at them and compare the pictures. I bet they would work just fine. |

This is another one of their fans which pulls 3630cfm but is much more expensive.

Calculate the square inches of coverage and subtract it from the core surface. That electric fan has to mount close to the core and will only draw efficiently for the area it covers.
The stock fan draws from the whole surface since it uses the shroud and extends just out of the shroud to take advantage of the extra draw created by the air tossed out of the shroud. There is probably a more accurate description of this, but that is the best I can do right now :? With a custom built shroud the efficiency of a single 16" fan could be improved. Would it be enough? Maybe. I prefer the twin fans for one more reason. Redundancy. If one quits, there is still one to get me home. All in all the stock clutch fan is pretty hard to beat. It is dependable. Cools pretty good. and really doesn't hurt performance or mileage much. I installed the efans to better match the lower operating temperature thermostat that I installed. IMO, the stock clutch fan engages way too late, and the stock operating temperature is just way too close to the edge for my tastes. With efans I choose when they engage and I can cancel them for deep water. It is all about control issues. Maybe I need professional help? Nah! ;) |

Good info HJ. Flex a Lite #60 "Back Magic" 15" single blade is good to 97'. Later years got a thicker rad. I was told (?), so 98' on needs more cfm. That dual 480 will pull 3000cfm for hot climate use. The 210 pulls 2500cfm. To calculate the clutch fan is way to hard, to many variables. RPM, # of blades, pitch of blades. What it pulls at idle is not what it does at 2k rpm. |
