New invention...3rd fan setup for engine bay

Here's the latest of my little inventions....the first involving this Focus. Feel free to build your own, but if anybody wants to buy the design for possible resale, PM me.

The idea here is to remove some of the hot air that tends to heat up the engine bay of these cars. I suspect this design could be applied to most of the Focus models, with modifications of course. The air is blasted downward, and out through the exhaust tunnel. This mod would be particularly effective when in slow-moving traffic.

The whole setup is in it's initial stages, and under-going testing, so no temperature readings are available yet. Obviously the more powerful the fan, the better it will work. I have several different fans of this size (120mmx38mm). This one has an aluminum frame, is rubber mounted to it's bracket, and really cannot be heard if the AC is on. There's enough space available back there to mount two fans, side-by side.

If you're doing this yourself, make sure the fan is mounted to the engine.....or to the body, not to both. There has to be some movement available. The setup as shown has about 1" clearance to an AC line.....should be plenty if your motor-mounts are in good shape.

How to power it? Several ways....manually with an on/off switch, wired to come on with the ignition, wired to come on with either radiator fan, controlled by a temperature sensor, etc. I'll be testing various methods. Ideas or criticism welcomed.....





All the photos of this setup can be seen in this album

If you remove your rubber weather stripping from the cowl it will lower you temps alot more than that fan.............

lol is that a fan from over the oven in the kitchen? not a bad idea but i dont think i could do that , thats where my turbo setup is going. 03 orangesvt is right though, just cut the weather striping and you'll be good.

Perhaps so about the weather-strip.....maybe not just sitting still in traffic. This fan mod avoids opening up the rear edge of the hood, which affords possible entry of engine fumes into the cabin, and water splashing into the engine bay during heavy rains.

It's relatively easy to do.....I had to drill a single hole into the manifold heat-shield. The fan comes off in seconds.....three nuts hold it on.

I have heard people talking about cutting that stripping, but what happens with water and/or snow then?

water gets in the bay regardless... so its not going to affect it.

so what is the point of this mod? A cooler engine bay? for a stock or nearly stock car it's pointless.

err.... i think you'll need some kind of funnel.. or it just gonna get ambient hot air from the exhaust...

you need to find a way to channel it..



personally i think inventing stuff is cool.. and its a cool invention...

but i wouldn't do it. rear seal is fine enough for me... and now i've opened the front end by a few mm... i think i'm good.

I did this for several reasons......my hood is completely sealed on all the edges. I added weather-strip in a bunch of places. The rain channels on the edges by the fenders have been modified to dump any water that might get in, to the outside, not the engine bay. The only place water enters the bay is through the radiator, when it's raining.....or maybe driving through puddles. Needless-to-say, this sort of sealing does raise the eng bay temperature.

I have never liked the idea of water getting into the eng bay just sitting there, in the rain. This eng compartment stays dry unless I drive in the rain....seldom. Then.....I'm going to install a Steeda SRI, and I want the filter to stay dry, and not be hurt by hot intake air.

This setup is one of the steps to insure that will happen...

Besides.....black cars run faster, and three fans cool better than two. Right?
