<![CDATA[Electric Fans+Save gas+more hp]]>Whats the best kind? I know they help save gas and add a little hp if you have a fan running on your belt. Opinions? I want a good blowing one that doesn't cost a lot and the best place to get one.

NEVER would have guessed that they weigh close to 10lbs though. Shit, that's like spinning an extra wheel.

The fan weighs in at 4.2 lbs as well. By themselves the 8.8 pounds is quite a bit, though not 12hp by itself. See post above for rest of explanation.

The above was done on an RX-7 everything else was stock except they eliminated the fan clutch and fan and added an electric fan.

Do you guys have any sense of how much 12hp is? Especially when we are talking about a little fan! If that fan was replaced with a similar electric fan, that fan would be drawing 750 AMPS!

Nope, Dave and his 7.77 second 1/4 mile supra have no idea what 12hp is. Do you understand what rotating mass is? Let's say the standard fan clutch and fan weigh in at 5 pounds for conversation sake. Just by eliminating them you would free up some horsepower... ok, now let's add in the resistance of those blades as they are pushing air through the radiator. That rotating mass has probably gone from the 5 lbs that the parts weigh to over 100 lbs of resistance that has to be spun by the engine itself... add a 100 lbs weight to your crankshaft pulley and see if your car performs better or worse.

Getting rid of the clutch fan also get's rid of the annoying whoosh under the hood it creates.

Raider is one of the few people I will take at his word on this. It does make sense though, with a fan clutch and fan the blades are ALWAYS spinning, sometimes more aggressively than others but still always a load on the system to some degree. Electrics kick in and out more efficiently and only come on when needed. I can easily see that being up to 12HP.

On my 01 5.4l f150...I gained 12hp by removing fan clutch and fan and replacing with Efan

Any dyno proof of this?

The power to drive them has to come from somewhere.

However, I kinda doubt you will have any noticeable "gains" buy doing this on most vehicles.

or, you could just go the junkyard route. Just make sure that you get something with enough flow and that you install a temp sensor to trigger it on/off when needed. A few years ago I took a job with Nissan and shortly after they had a massive recall on the electric fans out of the Nissan Titan's. I loaded the back of my Jeep up with at least 20-30 electric fan's. There's a couple of boosted Honda's in Louisiana running a Nissan Titan fan now. They were super thin, mounts were easy to mock up, and have great flow.
