Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Cheap forced air induction

Or why not build an electronic turbine setup with alternating fans. You could definetly increase the PSI that way.

Hmmm.. i've got an idea brewing in my head. Yup.. turbine is right. I'll construct something out of cardboard, and show. It'll help with the thing about cheap forced air induction.

If you don't like my ideaa fine, but no need to mock me.

I saw this actually on tv yesterday, its kinda
the same idea i think, from what they say seems awesome...not sure, check it out...

I might purchase one (Tornado Fuel Saver)just to see if it actually works. If it works, then the overall theroy (spinning air is actually more stable)is sound, but unless someone has ACTUAL dyno data to post, then it doesn't really matter. Do the before and after dyno data to support the theroy (just to appease the masses). I'll do the same and post the results if I decide to purchase it.

The problem I see with the proposed centrifugal fan is that while it may be able to provide the necessary cfm (per manufacturers website), it can't provide any pressure increase.

Look at the plot from the manufacturer. Its max pressure output is 1.2 inH2O (inches of water) at 0 CFM. That translates into a whopping 0.0433 psi at no load airflow. At max flow (262 CFM), it would be able to provide the air volume, but only at atmospheric pressure (0 psi boost). So it really wouldn't do much of anything that your airbox isn't already doing.

Looking at the electric supercharger page, you'll see that they give an example under their product desciption page saying that their unit provides the air at about a 0.5 psi pressure boost. That's how they can claim to increase horsepower. But still, it seems like a relatively low amount of boost that the solution could really provide, especially for $300. I'd just as soon use the money on the stock exhaust and probably see better gains throughout!

That's my take on it.

Boost = increase in PSI = HP
Force Air = CFM = Quicker response

I'm looking to increase the amount of air available to the intake.

The Tornado is a good idea gone bad.

So if my idea was able to produce an extra 1-3HP at lower RPM and increase throttle response by 10-20% would anybody be intested?

Sleeper, I wasn't mocking you I was actually quite serious.

All you need are a set of fans that can maintain a positive pressure.

Say 3 that rotate clockwise and 4 counter clockwise?

If you can produce a cheaper E-Ram I'll be interested, price depending of course.

I was thinking about your RPM vs. always on Q. heres what I think. If possable it should be RPM dependant but with WOT over ride for Max blower RPM's. So at regular driving it would always be on giving alittle better performance, But at WOT there won't be any motor spool time giving max perforamance from the start.

I had one of those tornado air type things once. It was the a ' spiral max ' actually, I used it on my old sephia. (okay, so it was a new sephia) I did several tests with gas mileage and 'percieved' hp increase and didn't feel any. I kept a good log of fuel mileage of about 70k. I tried with and without it and didn't see a difference. Maybe it was just my car, who knows. The idea was definiately interesting.
I also have some info on an electronic turbo, similiar to the E-Ram, but computer controlled. If anyone is interested I'll post the specifics. It seems to me like it's better than an e-ram, but of course I have no hardcore proof.
