Electronic Cold Air Intake?

So the other day I was doing the usual ebay surfing and stumbled upon the electric superchargers. I researched them to see if they actually worked and... nope. But then the idea came to my mind to use a fan to draw colder air into the engine bay using a small fan.

Right now I have a cone filter with the stock resonator. The problem with this is that it pulls in air straight from the engine bay. I still have the stock tubing that normally connects to the bottom of the airbox leading to under my intake. To help the colder air get to the intake I am thinking that I could attach a 4" duct fan, which moves air 100 cubic feet per minute, to the end of the stock intake tubing directly under the cone filter. I have airplane switches in my dash that I could attach it to in order to toggle it on/off. Does anyone else think this would work? Any suggestions? Just throw any crazy idea you've had out there.

your engine uses several times that right now.

sounds like you might like a turbo charger.


But first....... are you sure that your plugs are new, oxy seniors new, ?

If not, a good tune up.

Start there.

Ya I've done an entire tune up already and I'm really wanting to stay NA. Would that amount of colder air help the intake at all.

The reason I wasn't going to use a regular CAI is because I want the least restrictiveness as possible. The cone filter with a little bit of colder air being pushes under it would be free flowing as a SRI, yet with colder and fresher air.

I wouldn't think a fan blowing air at a cone filter would have an appreciable effect on the volume of air entering the engine behind the filter.

The point to the fan isn't to force more air into the intake. It's to allow colder air to be available for the intake to take in even though it is located inside the engine bay.

Your 100 cfm fan got me thinking about how much air does the engine use. So I worked at it and came up with 1887.78 rpm as using 100 cfm.

So armed with this information, I can now go into a bar and order me a cold beverage. When they bring it, I will inform them of this and I don't have to worry about getting thrown on out as long as I have put a fiver on the counter.

Would you mind sharing how you worked this out? I would like to be able to figure this stuff out when theorizing mods.

a 3 liter engine is 183.0713 cubic inches

being a 4 cycle engine, only half of the cylinders do an intake stroke each revolution

This equals 183.0713 divided by 2 or 91.53565 cubic inches per revolution
Rounding off to 91.54 cubic inches

A cubic foot of air equals 12 x 12 x 12 or 1728 cubic inches.

Divide 1728 by 91.54 and you get 18.8778 revolutions of the engine to use one cubic foot of air.

At 1887.78 rpm, the 3 liter engine is using 100 cubic feet of air per minute.
