Possible stupid intake idea... or not? Little long...
Okay, a lot of people prefer the hybrid intake setup over the CAI, because they believe the resonance from the longer tubing causes a loss in power... I recently saw a post by another member stating that he had turned his CAI into a hybrid intake, and then ran some tubing up to feed the intake colder air at speed... Now, what if we used one of those 'worthless' electric turbo's to feed air towards the intake, any benifit there? It would keep cooler air moving towards the intake even when the car was at idle, preventing the intake from soaking up heat... I also thought of trying to combine this with some sort of heat shield like a lot of Honduh and VW intakes come with... Just an idea, I don't have the money to play around with it right now... I'm done rambing... 
or not..
Throw a tornade fuel saver in there and you got a monster.
Seriously tho, if you put one of those electric supercharger fans, you'll be eating up too much power, you might as well make a cai with an electric supercharger. I think that should help it. Everyone knocks the electric supercharger, but if it were properly designed, it might work.

It was just a thought anyway, I wasn't thinking of using the fan to get any boost, just keep things cool, I know it's not good for boost, and the tornado is a POS...

I've been trying to come up with a good design for something to feel air from outside-in without using a hood scoop, and utilizing the short ram. Been so busy with moving and work though...I'll keep working on it.

I was considering adding a fan to keep the temp down at idle when I first put my hybrid intake in but never got around to it. I did leave the stock intake snorkel and lower half of the airbox in place to bring cooler air to the filter. For the most part it seems to work very well -- I did an intake temperature test similar to the one Str8ridin (here) did and found that at speeds over 30 MPH the intake temp quickly drops to near the outside temperature (within 1-2 min.).
The temperature would not rise very much on short stops (30seconds- 1minute or so) but after idling for a minute or two the intake temp would rise to about 30 deg. above the outside temp and continue to rise. It would be interesting to see if a small fan would prevent or reduce this temperature rise. I have a 12 volt fan left over from an audio project, perhaps I will try to rig something up through the stock intake snorkel or a separate hose and test the intake temp to see if there is any improvement. If I get around to doing this I will post my results on the board. If I have positive results I will investigate whether a bigger fan would work better and figure out how to turn it off and on.
If this does work I think it would have the most benefit at the track since you have to sit motionless for several minutes while you wait for your turn to run.

OK, here's a wild idea for a short/hybrid intake.
Air to air intercooler.
You'd need some fins on the tubing to get the radiator effect.
Then, encase that area in a plenum.
Finally, put a fitting on the plenum so that you could run some compressed air (or CO2) through the plenum. If you hooked up a small scuba tank, you could vent air through that plenum while waiting for your turn at the starting line.
Heck, you could put a nozzle up near the filter for that matter. As the air expands on its way out of the tank it will cool off (Charles' Law, I think ... it's been a really long time since I was a USNavy diver.) and give you ... a cold air intake!
Too much work for not enough benefit? I don't know

You could measure the voltage of the slectric signal used to control the speedo...and see how it changes say from 0-10 and over 10 or something like that, and then just make a little circui that would switch on the fan whenever your speed dropped below the set point (which you could even make variable). This would help while you're stopped since it seems to work enough on its own while you're moving
just a thought

Good idea, but first I would want to make sure a fan actually helped before I messed around with seting up a control for it.

I jus see there's enough space underneath the engine bay to make some sort of a scoop and use a long flex pipe and put it up in front of the intake or something. it would require moving the battery around and umm.... maybe puttin on a good sort of mesh for filtering out any road debris.
