how many cfm does the stock clutch fan pull and what would a electric have to flow to be effective?

i found one i want to get and i think its like 1675 cfm would that be enough?

 

Most people putting in electric fans are using fans above 2600 CFM for effective cooling.

Did your stock fan clutch fail?

 

i took a fan out of a mid 90's boniville. its huge and it works. as long as you have a temperature switch to not let over cool.

 

It's hard to overcool a car, that's what a WORKING thermostat is for. It's closed until it reaches operating temp.

 

Yea nowhere is correct. Its a good idea to replace the stock fan with an electric fan anyway, correct (I've read this in many places)?

 

Big waste of time and money to replace the stock fan unless you have a bad fan clutch.

With an electric fan replacement there are the issues of the considerably higher amperage load on the stock alt, and if the fan chosen is a poor choice, there is potentially problem of overheating or improper cooling.

 

1600 cfm Will do the job!

Been there done that!

 

Agreed, unless your situation forces you to run an E-Fan.

As far as the amperage load, if its done correctly (temp controlled relay, etc..) the load isnt as EXTREME as a constantly running fan. I just dont think anything can cool like the stock fan can.
