Clutch fan removal, Is it a worth while mod?

[JDMbyBlood]

Is the performance gain worth the removal of the clutch fan? Those of you that performed the mod, what did you use for the electric fan control? I found controllers priced from $20.00 all the way up to $180.00. I guess the Altima fan is the way to go. (From what I've read.) What year Altima should I look for? Do any of you have a link on how to wire up the fans?Thanks....

Pretty sure that any KA powered altima is going to have came with adiquate fans to cool a KA.

The first preformance benifit i can think of is hearing exaust instead of fan roar when reving the engine.

I noticed today that my AC fan is where I wanted to install the Altima fans. I was thinking mine was in front of the radiator like my buddies, I guess the SOHC and DOHC placment of the AC fan is in different locations. I assume that I remove my AC fan and hook up the Altima fan. 1 for AC and the other for radiator. I guess I'll go and do some research.... I've only had my car for 2 weeks..

boznuttz, Thanks a million for the link. VERY helpful in my quest to dump the clutch fan...

i plan to just forget to put the clutch fan back on when i reassemble the KA

theres a junkyard close to me that has a shed full of electric fans (seriously FULL of them) so i'm just going to go buy one and if it doesnt work bring it back. I'll keep that up until i find one that fits, works well, and is semi-quiet.

I'd say its def. worthwhile if you get a good deal on the fans

I had my clutch fan lock up on me one day while I was out runing a 5.0 Mustang. At about 6000 rpm the fan exploded and put a dent in the hood, a hole the the battery, and runt the bearing in the water pump. So that is why I have a eclectic fan on my car.

Over the summer my a/c auxiliary fan broke. I’m not sure what had happened, but by the time I realized what had happened 3 of the 4 supports had broke - this lead to the fan “kicking” into the mechanical fan shroud and the radiator when it turned on.

I opted to purchase a FAL 210 to replace the factory electric/mechanical fan setup. This package included a dual fan and adjustable controller for $240 (at summitracing.com). The setup was the perfect width. However, it required about 1 1/2” to be cut off of the bottom because it was too tall.

I had the controller set to a fairly low temp setting and I must say that over the summer the fan only came on once. This was while idling at a bank drive-through for 3-4 minutes. I didn't want to believe that the trend of using the a/c fan alone would be enough to cool the car, but now I must agree that that setup would probably work fine (at least for my situation). However, if I would have FI or live in a hotter area I would not want to relay on the a/c.

I must admit that I did not notice any gains in acceleration, throttle response, or mpg without the mechanical fan. I know in theory that removing weight/resistance off of the crank should have improved all of these things, but the effects just were not large enough to be noticed.
