good points also bryan, i'd bet that is was done parked and not moving at which point that car does not suck as much air, as many of you can tell by reving you car in neutral it doesn't sound as mean as it does when you are moving because it's not sucking as much air. and once again, other factors play into the hp side of the intake like smoothness and intake velocity.

Now don't go and throw a tantrum, Steve. You know we all love you around here.

I too apreciate Steve and his input at the ORG.... Oh by the way Steve, Hurry it up with my intake ! Im racing in May ! . iwant to BRAG about my Frankencar, the powdercoated Red one !!!!

Larry discusses this more over here. He also goes to the extent of saying: "My results do indicate there is hp gains with an aftermarket intake or by removing the factory cool air box. But isn't the latter easier?".

From Larry

I ran it at full throttle in gear. The vacuum maxed out just before the shifts. I only read the 1-2 and 2-3 shifts. There was zero vacuum at lower rpm. I am not sure exactly where vacuum started building but somewhere above 5000 rpm approximately. I would have to be able to look at the vacuum gauge, tachometer and road ahead to get more readings. Need two buddies to ride with me. One for vacuum gauge, one tachometer and me the road ahead. Below 5000 rpm I don't think the factory intake is a restriction on my car.

Larry

Thanks for the clarification, Kev.

From Larry




I have modified my cool air intake to see if my vacuum lowers. The following pics show how I have cut out the center pillar and added a small pillar of my own made from hard wood dowel. As you can see, I contoured the leading and trailer edges to allow better flow.

My initial tests indicate I have improved flow. On the 1-2 shift I got just flicker on the gauge, maybe 1/4" of Mercury, on the 2-3 zero. Previously I got about 1/2" on both. I can't explain the 1-2 flutter although I believe my transmission shifts lightly higher on the 1-2. If this is the case then perhaps my modification is marginal but improved. I am reasonably sure that with a good flowing exhaust system I will have mountains of vacuum to rid.

So I guess we're back to Steve's point, Kev. Is vacuum the only important measure of an intake's performance? If so, how would Larry explain dyno runs that indicate substantial horsepower increases for aftermarket intakes, all other factors being equal?

Larry never disagreed that there's HP gained w/ an aftermarket intake (see my previous post). He's saying that one can achieve it just by modifying the airbox.

Turbulence/flow should play a factor. Have you ever tried emptying a two liter bottle of water upside down? If you leave the bottle upside down, water would slowly blurp out while air goes in. If you give the bottle a little whirl counterclockwise/clockwise, water comes out at a MUCH faster rate.

Airflow intot the throttle body is probably not as extreme as my example, but you sort of get my point, right?

Most of these aftermarket intakes provide better flow than just unhooking the stock intake box.


This is my theory.....

Based on your Theory... would you agree that the Tornado Air Intake would work on cars?

But that causes a lot of turbulence.

I wonder if it could work in conjunction with an aftermarket intake like the Frankencar? It seems sound in theory however I am very skeptical of "infomercial" products.

but what about the tornado effect? makes coke go down faster... why not air?

ok. just playing with ya.

Right. Got it!

Hahaha! I know you're playing.

They have the right idea, but the product doesn't work as planned.

OK. Let's play with your theory for just a minute, Kev.

If turbulence exists at the point where the meter is measuring vacuum, wouldn't it tend to affect the meter's readings? I'd expect there to be some variance, perhaps intermittent, as the measurements are taken. But I haven't heard that any such variance exists. Perhaps that's because the meter isn't sensitive enough to detect the variances. But if the meter isn't sensitive enough to notice the difference (assuming it exists), is the engine sensitive enough to react to it?

And no, remykins. The Tornado Air Intake is worse than useless! Do a search if you'd like to learn more about it. It's right up there . . . or should I say, down there . . . with the Electric Supercharger (http://www.electricsupercharger.com/).

OK read my response in the general forum.


-Lemming Watch is ON~!

That has got to be the most retarded invention I have ever seen. Its up there with those coil adaptors that make your spark more intense(which I was stupid enough to buy like 8 years ago)
I would never buy the tornadoair, it just seems like it might have a good theory behind it.
Like the saying goes if it looks too god to be true then it probably is. Ill take proven results from a trusted company any day. So despite all debate I will be ordering my intake as soon as I get the money

Monkey boy gave wrote an excellent post in the General forum.

Thanks. I read it.

I'd like a valid response, from all the LEMMINGS on THE .ORG.

Like Bill said, if I make a comment prove it, I've done it.

Rebutt me.

-I'm sick of this "game."

Victor in the General forum has summed the therory up the best!

I do like Kevin's water in the bottle theory though. You are actually creating a vacuum in the bottle is the reason the water doesn't flow out freely. The weight of the water creates the vacuum. Call it turbulance if you like but eliminate the turbulance, by putting a hole of correct size in the bottom, and guess what, the water flows freely, increasing the gpm, not cfm in this case. You have reduced the vacuum!

Finally able to post, eh?

Yea buddy! Thank Kevin...

link, i can't find it.

and Kloogy i'm having them made this week.

-steve

Thank Jamie. I assume he fixed your account.

Yeaaaaaaaaa Buddie! Thanks Jamie!

So gravity is present in a vaccuum created by the water ????

so air being displaced up is sucked up by the water that is flowing down ?



-Its all right there.
