E-Fan vs. Visko Fan
 

Hi guys!

I know the pros and cons of a E-Fan...

i only want to know how much m³ the visko fan per hour...

and with an e-fan, what is better?

blowing or sucking?

thank you!

do a search - it's been discussed ad nauseum. fan behind the radiator pulling air is better.

Wouldnt an e-fan suck just like the clutch fan? either way look here:

I have the E-fan mounted on the "engine compartment" side, then blowing onto to engine. This topic has been an issue for some. If the fan is blowing away from the engine and the fan is mounted like "above", the car will overheat.

Does this answer your question? The clutch fan works better (moves more air) but the E-fan looks nicer and is easier to work around.

ok, thx 4 the blowing info...

but what i really want to know are the m³/hour of the Visco Fan! :/

no ideas?

so i've seen that 2500 cfm/h are the minimum 4 a rotary...

so, i can get a efan with 4000m³/h, thats 13,333.33333 cfm/h!?!?!?!

1 cfm ~ 0,3 m³ or not?

I think that should be enough to cool the rotary like the visco fan or not?

No.

1 CFM = 1.699m³/h


4000m³/h = 2354 CFM

No one knows the flow volume of the stock FC fan, partly because it varies according to engine temperature and engine speed... if it were as simply as revving it to 3000 rpm and throwing it on a flow bench, hell, I'd fund the $30 to test it.

Also, there is no such thing as CFM/hour. You measure flow, in your case, as cubic meters per hour, or more typically for Americans, in cubic feet per minute (CFM)>
You cannot have cubic feet per minute per hour.
The stock fan flows as much air as the engine need to maintain a given temperature, and only that amount.

What the hell... learn sigfigs.
