I thought the reason you were going to go electric is for lack of space? The flex fan might only be 1-1/4" @ 8000rpm, but when they're only at ilde they don't flex much and will be a lot wider.

its 1-1/4 at idle, its the lowest profile flex fan they have, just checking my options before i drop $240 plus on an electric fan that i dont know is going to cool my motor for sure.

if i went with the flex fan id run the fan and a 1/2" spacer, so it would be tucked up really close, but i dont know if i should go 17 or 18(if i even do)

Weren't the flex fans the one that people were having problems with them blowing apart.[7]

[iagree] The flex fan will probably suck into the rad worse than a regular one when it comes to water. I think a taurus fan might be what your lookin for.

Flex fans blow, they cool worse than mechanical fans and have been known to blow apart. Not particularily efficient, either, they sap more power than a clutch fan. Not worth any amount of money.

I'm positive this topic has been discussed in the past, and the consensus (big word!) is that flex fans SUCK!!!! I've seen 3 different vehicles with flex fans lose a blade....
1: '69 Z-28 blade breaks off and sticks in hood!
2: '84 GMC full size blade breaks off and sticks in hood!
3: '77 Camaro blade breaks off and sticks in overflow bottle!

I refuse to work on a car with a flex fan if it involves me working in the engine compartment with it running. I've also read a report where a blade broke off and severly injured a mechanic.

The chances of an injury ARE slim, but why the hell should I take that chance for what I get paid/hour!!!!:D Hell, without one arm, I couldn't go quadding/sledding and it would be a real bitch opening twist-offs anymore!!!
