Ok so the S4 TII has just been rebuilt. Im dropping in a Koyo Radiator and want to put in an E-Fan to lose the stock space sucker.



My question is for those in the know.... not those that just say "oooo that ones prettier.

Need to know about amperage and all that stuff. here are the two I am thinking about.

Which one do you think will fit better and provide the best performance? I know a bunch of you have Koyos so help a brother out.

 

when it comes to e-fans (actually cooling in general) it is all about CFM. Get the best fitting e-fan that pushes the most CFM (get the dimensions of the new radiator). I would highly recommend making sure it will fit behind the stock shroud and also make sure you still have your belly pan. Even if you have a bunch of airflow it can't do the best job unless it is directed where it will do the most good.

 

Agreed i would go with the second choice seeing as the CFM is 300 higher and it looks like the stock shroud will go back on it with little modification.

 

Ok. thanks for the responces.

 

summit sells a great e-fan...sucker moves 3200cfm of air....now that is cooling.. a little on the expensive side but worth it. CYMFC3S posted the link to it a while ago...

 

Summit is where I found these. Thing is nothing fits quite right and I dont want to have to keep the shroud. its starting to look like mt offtime at work is going to be fabbing something.

 

actually, if I had a Koyo with the stock fan shroud and drove my car all the time, i would stick with the factory fan clutch. I love e-fans, but sometimes Ive seriously considered going back to stock. Ive had 2 circuit boards fail, 1 motor fail. Thank god it hasnt stranded me out on the freeway in the middle of the desert yet. What you gain in engine efficiency and "coolness" you loose in simplicity and reliablity. Just a thought....

 

Truth is I thought about that but I live in western washington so dont really have to worry aboiut desert like heat. More worried about space, not to mention Id rather not modify the aftermarket pulleys

Any temp issues with that? What are you using as a switch? Always on or is it wired into something?
