electric fan conversion

Has anyone done an electric fan conversion? My A/C wasn't working right, so I took it to a shop and they looked the system over for leaks (they put uv dye in last time the R143a was filled), but couldn't find anything. The mechanic told me the fan was turning slow and causing the compressor to cut in and out to keep from building too much pressure and he thinks the fan clutch is shot. I've been looking at electric conversions, but one I found was over $500. Hayden makes an electric fan I found at O'Reilly Auto Parts for $65. I'd probably need two of them to pull enough air through that wide grill, but that's still only $130. Even if it doesn't come with mounting hardware (but I think it does), I could build some sort of frame to hold the fans and still only have $150 in the thing. Also, I've heard that electric conversions unleash about 5-10% more power and fuel economy. Anybody know if that's true?

I would use the flex-a-lite units. They are a little much, but they move a lot of air. I put one on my chevy when I replaced the motor with a 383 and it works great. It gets tied into your ac system and will change the speed of the fans. They really are nice units and worth the money. The other nice feature is that if your truck is not up to temp, the fans will not turn on. Helps your truck heat up faster in the winter.

On one of the other forums several guys put dual efans on their duramax's and they overheated under load... I wouldnt do it. what I'd do however is add an aux fan in the front, something that is on my list of things to do. problem is there is very limited space up there and from what I could tell, the biggest fan you could get in there would be 10" assuming a 2"~3" thick fan @ the motor. there just isnt enough room at the front of the stack.

I went to O'Reilly today and looked at the 12" unit. The guy at the store said a lot of guys bought 2 12's for conversions, but they were probably gassers he was talking about. I measured my radiator and I'm pretty sure the larger 14" and 16" units will also fit. They are only about 2-3 inches thick. Two 16's would cover more area of the radiator than the standard fan. My maximum weight is about 13000#, but usually between empty and 9000# gross combined weight. Thanks for the info so far, guys.
