hello, i was browsing eBay today and found and interesting intake mod claimed to help increase performance. it is essentially a electric air blower that you put in front of the intake. now the idea seems cool it would be nice to have it on a switch and be able to boost hp when you need it. but I'm thinking this product is a total gimmick / ripoff. so let me know what you guys think.
here is a an image of it
i found it by searching "mx3 filter" on eBay

Its a joke, we've found that before.

Although I remember one guy did install it and he said he did notice a little difference at higher speeds...

It's a scam, don't waste your money.

OK, I have a Jesse idea. We've used venturi air movers that are very efficient. For every cu.ft. of air you put in 25 cubic feet come out. So if you have a source of compressed air you could use this venturi to ram charge your intake. Varying the air you put it varyies the total output. Now, where to get the pressurized half from. The unit I'm speaking of is the size of your VAF. How cool is that.

It's a hairdryer.... you can make your own if you REALLY want!

yea just get everything port and polished in stead. although i saw a video on you tube the other day where they used a leaf blower to do it on a dyno and they got like an extra ten horses but i've never seen any real documentation helping these out

buy it..i dare you..

Ah those. They're more likely to damage your engine when a fan blade tears off.

They'll lower your overall performance, especially at the top end, by creating a blockage in the intake.

Look at the wires; they look to be around 14AWG. That means they'll carry at most 15.. maybe 20 amps. 20 amps at 12V is 240 watts.

To give you an idea, a supercharger at 6psi (ie. ~ +50HP) draws about 5000 watts.

You do the math.

Yoda had that on his car, just before the TB. The venturi effect can increase exhaust speed, too. I don't know enough about it, and hate doing formulas, but I would L VE if someone researched it! However, it too is something that would be tuned only for a specific velocity, and may hinder flow at other RPM.

if you guys really want electric superchargers, go find the air blowers that nascar uses to push more air to cool the braking system. Found out about these back when these electronic superchargers started to appear, and before thomas knight came out with system. Did the math and they can provide you with about 8psi. The downside, the amount of power these things take. You would have to do basically what you have to the same TK design (note you can not run the TK design but for a short time) and thats have other batteries that arnt tie to your motor power the ESC (electronic super charger). Thus making this to where its not a supercharger at all but more like a shot of n2o. More of a downside, with the amount you would spend on batteries to power (you'd have to get something like a optima to handle the fact its constantly getting drained and also you'd probably want more than 1 battery), the actual motor to push the air, and everything else, plus the fact you have to pay for power to charge the batteries constantly from your house, you would spend less just getting a n2o system and management. Since in the long run it would end up costing less for the same amount of power.

Couldn't you run a switch and relay to charge the batteries using your car, like at stop lights or at highway speed or something? When the motor isn't being overtaxed, and you need it to sit running anyway.

So nobody have ever actually bought and put one those on?

I'm sure plenty of suckers did.... Probably no one here though.

yea electric superchargers dont work unless its the E-Ram those are dyno proven in import tuner to give around 20hp it says E-Ram puts out 3psi. Other than that a leaf blower would work better than a electric supercharger.

haha this thing would have to spin pretty damn fast to create enough compression to make a difference. thats how turbos and s/c's work. they compress air into the intake. you can't just blow air into it.
