[quote name='rowtareh' date='Aug 24 2005, 01:52 PM']how the hell can't you use the stock clutch fan, that makes no sense at all?
is there really a difference in the size of an s4 and s5 rad???

there are some differences between the s4 and s5 rad. I have an s5 koy rad in my s4 also. I cant see the stock fan fitting with it. I have an e-fan hooked up to a switch.

curious to know too. it just seems kind of silly that they were not the same size radiators. is it thicker, wider, longer? what is it????

I used a taurus E-fan on my old setup with the stock s4 alternator, and had problems keeping the battery charged at all. Even after a 4 gauge ground wire from battery to transmission. Depending on how reliabable your stock wiring harness is you may/not have problems. But I would at least recomend upgrading to an S6 alternator at some point.

If you are looking for every ounce of performance you can get - going to efans is the smart chouice.
You get about 20pounds of rotating mass off of the engine.
In my case (autocross) or even a drag racers case - you shut off the fans at the start line (assuming your engine isn't on the verge of overheating ( I am usuaaly about 170 at the line)) to reduce the alternater draw. And then turn the fans on when the run is over.
If your car is just a daily driver or cruising machine I would never bother to do the conversion.
However my twin 10" fans cool the rad MUCH better than the stock fan ever did

the koyo is a little wider and longer and the rad cap is in a different position then on the s4.
