Rock Posted January 14, 2015 Share Posted January 14, 2015 This is what I like, it's a dual 14" fan set-up with a carbon fiber shroud. Comes with a relay, alum. over flow a 48" hose (which i dont need) the guy said he would exchange the harness for the hose even up....$378.00. Good deal? any one run an elec. fan set up on these cars and do you notice a difference in cooling or any other positive differences?

502ci Posted January 14, 2015 Share Posted January 14, 2015 What cfm is that set up rated at and what brand of fans are those? Not trying to be rude but to be honest it kinda looks like two generic fans place on a carbon fiber board. Also it looks like it isn't even mounted and there are a bunch of extra tabs on it.

7tonemonte Posted January 14, 2015 Share Posted January 14, 2015 No real info in the ad as far as cfm. I'd call and try to get some details at least Quote Link to comment Share on other sites More sharing options...
Boots Posted January 15, 2015 Share Posted January 15, 2015 I always thought the shroud should itself should not be flat but have a depth to them like a pan (it's not like there's little room between the fan and the block) to create a vaccuum from the entire rad area not just where the fans are on the shroud..other than that it does look cool..no pun intended Quote Link to comment Share on other sites More sharing options...
Rock Posted January 15, 2015 Author Share Posted January 15, 2015 The add says 1700 cfm for each fan....He said the fans are a little different that what's pictured. They are a black and don't have the brass motor mounts like in the picture. Quote Link to comment Share on other sites More sharing options...
Boots Posted January 15, 2015 Share Posted January 15, 2015 I believe that the performance of the fans/and your cooling would be linked to the performance of your radiator also..from what I have read over the past while core size would also dictate cooling performance..4 row rads are not as effective as lesser rows??..and construction of the rad itself being copper or aluminum.....If your present rad works then I can't see why, at that cfm it wouldn't work..but I am a newbie at this stuff..just an info sponge..I have saved that product though for future reference and you can tell us all how they work,,,,just out of curiosity does anyone have the cfm rating of a 7 blade old style fan would be???

Rock Posted January 15, 2015 Author Share Posted January 15, 2015 I already have the 3 row champion radiator in the car and it works really well. Now this is just my opinion and don't anyone get butt hurt over this but that long shroud is just ugly. I have seen pic s of Montes without the shroud and electric cooling fans and it looks so much better. Quote Link to comment Share on other sites More sharing options...

dbreese Posted January 15, 2015 Share Posted January 15, 2015 Gotta be careful how companies rate the cfm on their e-fans. Company A may rate their fan at 1700 cfm but the cfm rating is taken with the fan not pulling through a radiator. Put this same fan behind a radiator and its efficiency can be greatly reduced. Company B rates their fan while pulling through a radiator and rates its fan at the same cfm rating, 1700, that is a good thing. I installed a dual fan kit for a customer on a mild sbc in an C-10 P/U. Generic 12" fans/ shroud with a 2 core aluminum radiator. Worked ok but a soon as the a/c was cut on the temps climbed. Swapped fans out for some Spal units and the problem was solved. Just my experience. David Quote Link to comment Share on other sites More sharing options...
Rock Posted January 15, 2015 Author Share Posted January 15, 2015 I have also noticed that depending on how the fans are wired they can push or Pull air. Which would be the preferred method? How does the mechanical fan work? Push or pull? Quote Link to comment Share on other sites More sharing options...
dbreese Posted January 15, 2015 Share Posted January 15, 2015 Pulling fans are more efficient. Mechanical is a puller. I have never seen the cfm rating for a mechanical but I'm guessing a bunch. LOL. I still have the old school setup but with a aluminum 2 core radiator, Hayden 2747 fan clutch, Stewart Stage II aluminum water pump, Autozone 15356 160 degree t-stat that is drilled, factory fan and shroud. Radiator is filled with deionized water and a bottle of Redline Water Wetter. Something else to consider. Some aftermarket e-fan shrouds have rubber flaps that open as air is pushed through when the vehicle is at speed. This is said to further aid in cooling.

Leghome Posted January 15, 2015 Share Posted January 15, 2015 Most of them pull the air through the radiator. Quote Link to comment Share on other sites More sharing options...
502ci Posted January 15, 2015 Share Posted January 15, 2015 I took a look at the link you provided, you might want to make sure that is not going to be a flat piece of carbon fiber (meaning that it would lay directly on the radiator) but instead a raised surface where the fans are able to pull every square inch of the radiator surface. I am not trying to sway you from buying this product I just want you to get a good product. Here is a recent link where we were talking about fans (not sure if you already seen it) where you can see some pics of the "raised" shroud I was talking about. http://www.firstgenmc.com/forums/index.php?/topic/12349-cooling-fan-question/?hl=%2Belectric+%2Bfans&do=findComment&comment=142926 1 Quote Link to comment Share on other sites More sharing options...

Trust me.....I am researching and asking questions. Don't want to spend 400 on something I can't use. 1 Quote Link to comment Share on other sites More sharing options...
Bluemalibu Posted February 21, 2015 Share Posted February 21, 2015 By the look of the light gauge wire (14ga?) the manufacturer of those generic fans do not appear to be very concerned about the need of their motors to draw very high amperage. That makes me suspect. Remember the laws of physics... if you want to accomplish substantial work, it going to mandate the expenditure of power. High amperage draw of 12 v electricity requires large gauge wire for reduced resistance and safety. We're just trying to help you from being burned here... not trying to put down the merchandise, but I would really doubt that those two fans could even move 1800 CFM of air through your radiator. I'm a DIY guy, and have had real success with using the OEM Mark VIII fans on three previous vehicles. So, I just pulled the Flex-A-Lite dual fans set-up below (Straight blade reversible version, with thermostat installed) off of the car that I just purchased. They looked new, and seemed to be up to the task of cooling my big block when I bought it in the fall, but it gets 120* here in the summer, and I believe that over-built is just about right. The measurements on it is 16" x 27". Let me know if you want to use it.

Bluemalibu Posted February 27, 2015 Share Posted February 27, 2015 Well, it's been a week since I made the offer to donate the dual fans to your build... I'm guessing by the non-response that you've decided to go a different path. So, let's see if we can't find a new life for the fans through SecondChanceRaceParts.

Grizzly1911 Posted February 28, 2015 Share Posted February 28, 2015 Not sure about the fans, But I used this http://www.summitracing.com/parts/der-16779 to hook up the fan in mine (not sure from what) after my engine fire. The adjustable controoler is really easy to install and set up took me about 30 mins Quote Link to comment Share on other sites More sharing options...
