ok so i have another one of those ideas, the ones where its either a good idea or im a total idiot.... what would happen if someone put a air sucking motor in-line between the intake manifold and the air filter? would anything happen? idk, i dont know anything about cars really and i had this idea last night while me and a friend we working on his car.. he didnt know either.

and on a different note.... last night me and my friend after we got done with what we needed to do mechanically to make it run again.. we decided it would be hilarious to make a hood scoop for his car out of sheet metal... omg it looks horrible... total time was about an hour. its big, different colored and held on by self tapping screws haha. its ok though because his car is a peice, a hardly running, 94 crap-a-lier.

your air sucking pump is called a supercharger or turbo.........

if you sit down and actually figure out how much air your engine pumps at redline, you will know that there is no way you will ever be able to pump that much air without a supercharger or turbo

What you're describing is actually a supercharger.
The problem is, an electric fan cannot build any pressure, or flow enough air to begin with, to make any extra power.
Anything like that is a fraud, will not make any HP, and is a complete waste of time and money.

im not talking about a super charger, i know what a super and a turbo charger are. yall dont know what im saying, and it was just hypothetical, it wasnt a product i seen. so im done...

Yes, you are describing a super charger.
A supercharger takes filtered air, and tries to stuff it into the engine. THe only difference between a SC and a turbo is what powers the unit (makes it's turbines/wheels spin). On a turbo, it's the engine's own exhaust gases. For an SC, it's anything but the exhaust gases.

The only difference is that the electric fan in your idea would be located before the throttle body instead of after it, like a typical SC setup is.

They even try to sell them on ebay:

ive seen these posts soooo many times over the years, no offence, but usually by newbies to cars,

think of it this way..

your putting a giant restriction into your intake path. IF you can find a product that can draw enough air to equil the restriction you just added, you just broke even for your power.

if you try to get more power, you'll realize that a Turbo or SC setup is what is needed.

ill admit im a newbie to cars, im only 18. i dont know anything about cars, not to start a sob story or anything like that but my dad wasnt around when i was young so i didnt have anyone to teach my about cars. im trying to learn from my friend who is a mechanic at a car dealership. but yea, like i said, i have random ideas sometimes and i just want imput on them.

I have some 4" fans that flow 200cfm. I had wondered about making a Y pipe one with a fan one without if it needed more to breath. But I thought with all the fuel management involved with forced induction that this seems too cheap compaired to how much time and money you would spend on the rest of the sytem.

even 2x 200cfm fans will not flow enough air if they were somehow able to actually create boost, which they are not able to.

You cannot use electric fans to create usable levels of boost at the price level you guys are looking at. Might be doable if you had a fat enough wallet (think 4 figures).

Consider that your car should be sucking at a rate of about 600 cfm or more...that makes her one good blow job :wink: Rudy is absolutely correct along with everyone else that has told you it is a waste of money and time. Buy a turbo kit or better yet, go talk to Mike and buy his S/C kit. :idea:

I really wish I wasn't so lazy right now, cause I know with enough searching somebody on sixthsphere has done the CFM math on how much our cars breathe, then you would realize that even ten 200cfm fans wouldn't be enough for any engine.

I couldnt find any thing on 6th sphere I found this tho.

http://www.squirrelpf.com/turbocalc/

I changed the CID(116) and HP(124) and got 181cfm at 6000rpm. Which to me sounds right. On qksl2's old webpage he had the math to figuring it out and I remember the cfm being around 200 at 7000rpm.
So fans are meant for cooling and will stay there.

A motor between the air filter and intake manifold? What? Can you explain it further?
