Intake Fan...Seriously

Intake Fan...Seriously
Seriously, if air intake is so helpful, why doesn't someone just take a high-powered 12V motor fan and connect it straight into their intake pipe? You could create some major air pressure straight into your engine.

It takes a lot of electrical power to run a motor like that, you could drain your battery and the gain would be very negligible in terms of CFM... a turbo or supercharger would be a much better way to accomplish boost...
On a similar note... If cold air is so helpful, why not hook up something between your intake and A/C - so the incoming air is really cold all the time? I'm sure there's a simple answer but I'm not really a mechanical person... I guess nitrous would be a better way to acquire the added HP...

If you want something drastic try this:
snow blower from sears(600cfm) $129
some tubing from local speed shop(home depot) $20,
relocate battery to the trunk
put the blower with modified fuel tank and exhaust under hood.
work out million other details.
Having boost when standing at red lite=priceless.

This idea has been explored. There is an electric supercharger on the market that says it creates 3psi of boost. Daniel B. Martin did a research project on this. Our conclusion is that from the provided information from various electrical blower companies that the technology is there to create an electric blower that would create a 9-12 psi boost for our maximum consumption. The problem is it would have to have a 12inch blades or would cost 15k and would last about 9 months of everyday use. Also, you mentioned a CPU fan... do this math, 3.0 litres x 6500 thats your maximum consumption for one minute. I believe its like approximately 19k litres of air to equalize the vacuum in your intake. Now remember you have to create positive pressure so you'll have to increase that to 3-12 psi to make it worth your while.
Good luck, great idea but about 15 years too early.

The electrical supercharger is not a good idea because there is no such thing as a 100% efficient machine. Power will always be lost from the conversion of mechanical energy to elecrical and viceversa.
You have probably heard of the new technology in hybrid cars were a battery is charged while the car is downshifting or braking and this battery is later used to move an electrical motor while accelerating again. Now, I know this is easier said than done but, What if an assembly like this is used also to create boost? We'll probably have to wait until some of this prototypes reach production, get used up and end in junkyards to test this.

Ok, this is just an idea, but I saw this on TV. It's a small plastic fan powered by it’s own battery supply (9-volt battery. This fan is connected to an insulated box, perhaps ¾ size of our car battery. Well, this box was filled with dry ice and once the fan is turned on, it draws air over the dry ice and out the fan which, when pointed at something, would instantly cool an object down. It was used on TV to keep regular ice from melting when “misted’ by this contraption.
Now, I don’t know where to get dry ice and I don’t know where to get this simple contraption, but what if someone were to put this little thing in their engine bay, connected to a switch on their dash and turned on when desiring to cool down their under-hood temps at the track? Even mist the intake with 0 degree air to bring intake temps down? hmmmm
Obviously, it has A LOT of short comings….but just an idea.

I'm not familiar w/ what's under the Maxima's hood yet cuz i don't pick up my car till next week... but aren't there ways to use piping a system that as ure driving, cold air from underneath the car will be pushed into the piping and in front of ure intake opening... sorry i'm a newbie at this. I'm sure this can be accomplished, my main question is that, if there is enough room for it, and has someone tried this before and had any success or probs w/ it?? thanks

The problem is if you suck up water into the intake you are completely screwed. One big puddle, suck up a bit of h20 into the cylinder. Intake valve closes. Piston comes up at ~800mph. Water doesn't compress well, at all actually....... Bang.... thump thump thump.
Not worth the hassle in my opinion....

What happened to the Maxima's battery? Doesn't this contraption sit right where the 12V battery used to sit??

Re: Re: Re: Intake Fan...Seriously
This is one of the funniest threads I've read in ages
There is one way to force air into the engine for a noticeable hp gain. It's called a supercharger!
I couldn't figure out whether the PC fan suggestion was a stroke of genius or plain stupidity, but I'll take the former since it made me howl...

eletric fan theory is really good idea (just not for today's technology)

I'm not here to wind anyone up. All I dissed was the PC fan, and I also said in the end that I believed it to be a joke (it says former, not latter). I said nothing about electrical fans in general.

Don't get me wrong, half this thread is thought-provoking too, and it's cool when people think outside the lines.

Actually while I think about it, if there is going to be a great electric fan idea (and I have no doubts that SLC is right in that this IS physically feasible), where's the current going to come from? If it's not from a VERY heavy duty battery (impractically heavy) or solar (no chance) then it's from the engine. Of course a supercharger uses engine power, but so would a high-powered alternator, which would then go on to lose further energy when converting back from electrical energy to mechanical energy. I don't think the technology will ever merit a *practical* electric fan idea for this reason.

Hey, thanks for posting SLC. Once again, I'm not laughing at the idea, what's funny about this post are the midget/bicycle pump/PC fan posts (I should have made that more clear).
In no way am I saying that this is not possible, my point is whether it will ever be more efficient that superchargers driven directly.
How much current would that fan be drawing? It would be quite large wouldn't it? If you're recharging the extra battery from the alternator, then frequent gunning is going to kill the battery and you'd have to drive around for a while not able to use it (a directly driven s/c is available on demand). If you add another alternator, you're losing overall as explained above. If you're charging it from an outlet at home, that would work but then you'd have limited life before a recharge.
I wish nuclear wasn't so dangerous sometimes.. Imagine, no emissions, no gas, fast as hell, but nuclear outfall whenever you crash

My conclusion is that NISSAN didn't put these into their cars because from we could find it would cost about 15k to put one in that ran on a 12v powersource and it would only have a couple year life expectancy. Similar blower systems are supposedly used in the space program to re charge compressed air banks on space vehicles. (according to popular mechanics) I don't know too much about that, just the blurb I read in an article.
