but one that i know someone will find something wrong with which is why i am posting it first........

here goes nuthin........

refer to this diagram of my homemade RAM AIR system:

for any questions about construction of it please see my other topic

NOW FOR THE BRILLIANCE

what if i was to mount a small electric fan after each K&N????? the K&N should keep water out and there should be enuff room............

so whats wrong with this idea???? lemme know !!!!!!!!!!!!!!!!!

 

Fans wouldn't do anything except restrict air flow.

Removed air baffles, mandrel bent cat-back pipes (but stock replacment muffler, Dynomax Turbo and Catco converter are on thier way)

 

hmmm....... are you sure???

wouldn't they help get the air moving after being slowed down by the filters???

 

LOL!!

ok my friend explained to me today why it wouldn't work: because the faster you travel, the air is pushed in with more force..............so much force that the fan wouldn't help


just a dumb idea

 

SAYS WHO!!!!!
Back in the mid 60's
Jim Chapparal used FANS TO KEEP HIS RACE CARS SUCKED TO THE GROUND FOR BETTER CORNERING!
The next racing season, "Fans" were banned.
The stories of the original Can Am racing days, when dinosaurs made the ground rumble with unlimited horsepower and cubic inches of CHEVY RACING POWER (try the ZL-1 ALL ALUMINUM 427 blocks, with Kinsler mechaincal fuel injection systems).

Just that in this instance, your fan idea, will not be as effective, as you thought!

This is the same theory as the "flex" fans.
Once you get up to a certain (freeway) speed, those fans are walls, that cooling air cannot pass.
That's why thermostat clutch fans are kings!
Electric fans are second in that chain.

Uh using fans to create a vacuum to hold the car down is one thing. Using it to pump air that will eventually push the blades faster then they can go is another. A proplerly desinged ram air will begin to flow lots of air at a lower speed and gain as it goes faster. Personally I have seen a ram air setup that produced .7 PSI. Not alot but its alot for just ram air.

 

well since there is gonna be a twin intake on my RAM AIR what about putting a fan in one intake and leaving the other open


i could also have my friend design a KILL switch for it for me

 

The kill switch idea wouldn't work, because the fan would STILL be a restriction. Ditch the fan idea, it's stupid. The ONLY place you will ever feel it would be at idle. Just make youself a good ram air setup.

 

thanx Overclck

i figured that it had to be stupid for some reason.......mainly because no one has done it before

dont worry the idea is drained from my mind

 

IF you really want the fan idea, go back to World War Two.
Those prop planes had varible pitch blades.

CHD, I realized that the fans may work at "low pressurized speed", possibly assist.
BUT, just like with the Flex Fans for cooling radiators, after a certain forced air situation (or going faster), they become a wall of solid air, preventing what that flex fan should be doing, which is attempting to cool the warm radiator.

Same idea with fresh air induction into our drivetrains.
After a certain point it becomes a wall of air, not allowing what should be done, let in more air.

No way is your thinking stupid.
Just not as effective as it can be.

Back to the drawing board.

I'm still at the drawing board thinking of better ways to get air into my/under my Firebird hood, without hoses all over, vunerable to the ground bumps.
Right now, I keep looking in my Corvette catalogs for ideas about this air inlet project.

well heres one... While I was in the Navy we used venturi tubes to get rid of fuel fumes from drop tanks. Now I know this has been mentioned before but not like this. Ok heres the idea.


Get a venturi coupler in the intake tube. you need a compressor on board(I know I know) but anyway, If the compressor can supply 25 PSI continuous you can triple that volume with the venturi tube.


Well if you do not know how venturi tubes work here it is.
1. A venturi tube is a cone shaped metal tube.
2. If you can create a gross vacuum just behind the peak of the closed end of the tube it will draw a tremendous vacuum.
3. so you have a 4 inch venturi tube with the intake opening of 4 inches and the "exhaust" opening of 3 inches. Just behind the cones peak you have a ring that the compressed air can jet out twoard the exhaust side. This created vacuum will draw air through the intake.
4. With the compressor shut off the engine can breathe normally, but with the compressor on it will creat a low boost system in the neigborhood of around 1-2 PSI I think. I think it may be able to get more PSI but the lower PSI is fine because of the shear volume being moved.

 

That's a very cool idea.
How can we adapt this to our cars?
Have any drawings to show?

well...no pics right now it was just a spur of the moment thought...but if you get a power converter, and a small compressor(a mini tire inflator type might work I dont know) Anyway you get a metal cone with a tapped hole for the air inlet tube and have a cone nozzel jet to fit inside the small end of the cone. Then you install it with a "custom" intake tube. Just remember big end facing out closed end in so this would help mating it to the intake itself...Having the clean 4 inch inlet will help with the K&N filter though... No need to run the intake tube for the big end any farther than what is needed to make it fit in the compartment. You don't want a long intake tube going to the venturi tube, keep it short and simple. Heat will not be a problem so don't try a CAI...It will restrict airflow.
