Thought about this last night. Probably crazy as hell, but just wanted some other input.
I currently have an open K&N filter on my 305TPI and wondering what would happen if I install a small DC powered fan inline after the filter. It would have to be sealed in the air tubing, but I could manually turn it on and off to pull more air into the motor via dash switch. Would work something like those "tornadoes" they sell, but would be regulated and should be more effective.
Anyone else ever done anything like this? The cost to try would be cheap and easy. All positive and negative thoughts are appreciated, so let'm rip

you don't really want to know what i think, might hurt your feelings. if you think it's a good idea go for it, all you'll be out is time and money if it doesn't wrok.

Yea, I'm pretty interested to know what everybody thinks. I've got some pretty tough skin and can handle the abuse
Thats what this board is for anyway, to get info before things get too f**ked up

the "boost" you will see at idle will go away and be a restriction in the inlet before you reach 1000rpms....

It probably won't work, but I'll bet you could market and sell it to Honda drivers, and others that have no clue. Make it variable speed, and it might sell even better.

vader I keep trying to tell you on my honda some of those electric fans blow more air then what my carb is rated at in CFM :-p

somebody is sounding like a honda owner here.

your intake is only gonna flow as good as your weakest point. Like stated above you might see a difference at idle, but step on the gas, and the fan becomes a restiction in the intake because it can't keep up with the air flow, and just obstructs the inflowing air creating a bunch of turbulence...

these things become a restriction when you have a hamster powering your car, i can't imagine how bad it restricts when you have a V8 under the hood...

Thanks guys. What kinda cfm's are flowing through my standard intake? This is exactly the kind of input I was looking for. Just looking to play around with some different and cheap approaches to get some more power. Once again this site kicks ***!

Oh and BTW, We got all American made around here, NO ****

2002 F-150 XLT 5.4 Triton V-8 4x4 (for horse trailer)
2005 Dodge Grand Caravan (for wife)
2000 Buick Park Ave. (company car)
1989 GTA (the toy)


BUY AMERICAN!!!

I am a honda owner

the carb on my car is rated at around 150cfm
there are 12v computer fans that flow that much

but yeah on a big v8 it would be another story I'm s

pay them thar messicans

sorry I'm just stiring up I know but it's fun

messicans or "flapheads" (the South Park term reffering to Canadians) just kidding!!!

Yea I know that most of these vehicles are assembled either in or with parts from CAN or MEX. Gotta love NAFTA!!
My company has just opened a plant in Mex to comply with NAFTA guidelines for military units. Better start learnin Spanish.

And BTW, I had a '87 Honda CRX Si in high school. Loved that car and ran the **** out of it.

i think TPI engines are somewhere around 500-600 cfm if i recall right...

so look for something that flows that much if you want to experiment..you might want to look into marine blowers, they are little housed fans that you put in your engine room in your boat to clear it of fumes before you start it up. I've heard of honda owners using these, i can't believe they work tho..i guess its worth a try tho..

I would be concerned abt mounting a fan after the air filter.
When the airflow kicks up, the little fan would probably overspeed, throw the blades off due to centrifugal (sp??) force and they would be ingested by your eng.

Yuck!!

Do it. Report back with a before/after dyno test. We need some hard proof that it doesn't really work.

Good luck finding any fan that small that can push 1000CFM...

here's a 240 cfm fan...this little guy spins pretty fast too....you could maybe split the intake track and make something work. Like something like this, you have the filter, than a chunk of pipe, than a piece that is like a y pipe but splits into like 3 pipes, run like 3 of these blowers, than come out of all three blowers back into a single pipe then into your engine...

with a setup like that you would be 70 bucks poorer and maybe you could get a pound of boost outta that....

If i were crazy enough to bother doing something like this this is what i would do...

Instead of putting the fans inline i would use a sealed airbox. put about 20 200cfm fans in holes in the side of it!

That way if something flys apart your engine doesnt eat it and you also have alot more room to mount alot more fans

yea that would work also...prolly would be easier also....

my idea wasn't to put them inline, because each blower would be in 3 seperate pipes...

My final thought is, just go buy a supercharger....

use a honda powered leaf blower and use that. run an AC converter and go for it.

Get a gas powered leaf blower and convert the window pisser bottle to a gas tank for it!

Dyno proven results right HERE
$120 bux at Lowes. Works on pickups too.

thats funny...thats gas powered tho right???

you could soup up like a 5 horsepower motor, make it turn out like 10 horse, and put that under the hood and get some boost outta that

cool vid supervisor 42! Those must be some twisted bastards to think up **** like that. In the power supplies we manufacture, we utilize some very high speed 1000+cfm small dc powered fans. I can get one for free to try. As for it blowing into my intake, the screens on the MAF (yes they're still there)will block that. These are fairly ruggedized fans being that they are used in some military supplies we do. Be fun to try anyway. Although I do like the gas in the window pisser idea from 84z28350
BTW, is it possible to change a cam in these cars without pulling the motor? Just wondering.

my streaming sucks, you can't be serious. There IS no way that will work. Is there?

Why wouldn't it work? More air is more air regardless of how half-*** the install is. I'd rather put the money towards new runners, gears, or something more practical. At that point, why not just get NOS and have it slowly bleeding into the intake for more Oxygen.

All that leaf-blown air and then straight nitrous on top of that? I wonder how much more power they would have made by adding extra fuel? or if they had an 02 meter hooked up, I wonder what the a/f ratio was?

I did my cam while it was still in the car. It just barely made it out, i had to bend the X braces that go infront of the rad out a little bit to slide the cam straight out.

Remember the ECM is constantly monitoring mixture, when they blew in the N02 it saw the mix go lean and added fuel. If the mix went lean and it didn't compensate it would have dropped power, not increased it.

firebird45331: Sorry your streaming sux. Well I'm afraid it does work, and good for over +10 horsepower without the N02. Over +40 horsepower with the N02.
4.3 V6: 177.7hp stock, 191.3hp with leaf blower, 222.4hp with leaf blower and N02.
Never underestimate the power of us crazy people!
