aero turbine

[wallaka]

I wouldnt imagine a performance benefit over a muffler would exist.

As mentioned in earlier posts, think sound manipulation.

Then turbo "paddle" vs muffler, becomes as subjective as ones love of a flowmaster vs glasspack.

How do you know it wont work as I think it will? I know how a turbo affects sound, shouldnt there be reasonable expectations?

Doesnt hurt to think outside the box, wont hurt ya.

I am just trying to figure out why anybody would want one of these. If you want a turbo sound, put a turbo on it! Then you won't be an object of ridicule.

I'm trying to be as nice as possible. This is "out of the box" but not in a good direction.

How about a Mega-Watt sound system with the biggest speakers you can get in the bed of your pickup. Have a recording of a T/F leaving the line.

Idle up to some ricer at the red light and on green key the stereo.

Blow his little mind, his fake turbo sound and ruin his seat cover.

Its not about having a turbo sound. Its about taking exhaust sound in another direction, using aspects of. What this thread was never about, marketing, although based on other gimmicks, as described here, Im sure they could be sold. Whatever "they" is, as this was more of a rolling thought than any fixed concept.

Talk about sticking things on the end of the pipe for performance here is one for the intake of a m'cycle. Definately a performance inducer

Im well aware of those, crap no doubt.

Not a new thought, there are companies that market this very thing, although, it includes multiple car sounds and speakers under the vehicle.





Ill let this fade, seems everyone has this uncontrollable desire to say something is unable to work, just to be right, as opposed to thinking outside what you know and question, how could it work?

DONE.

At least it's a change from trying to make this:

I'm a pragmatic person, what can I say? This is the same reason I eschew ram air intakes, spinning rims and fake dual exhausts.

 

[XPC66]

What's wrong with fake dual exhausts?

 

[Lazy JW]

... seems everyone has this uncontrollable desire to say something is unable to work....

I never did figure out exactly what sort of "work" you are trying to accomplish.

Placing spinning vanes in a stream of gases to make noise isn't exactly a new idea; sorta reminds me of sticking a playing card in bicycle spokes (the novelty factor wore off many years ago on that one for me).

But hey, nobody ever said it had to make sense!
Have fun,

FYI, the ricer tail pipe addition that "sounds like a turbo" sounds like an intake underpressure ~ aka boost ~ high pitch ~ blow off valve, what it doesnt sound like is the exhaust of a turbocharged engine.

I'm a pragmatic person, what can I say? This is the same reason I eschew ram air intakes, spinning rims and fake dual exhausts.

Yet you find the time to hypothesize what wont work, based on your best guess, even with lack of total understanding. Everyone is hypocritical.

That was obvious. Turbo generally tone down the exhaust, so this noise you speak of? Subjective. Some state laws consider a turbocharger a sound "deadening" device and legal alternative to a muffler on vehicles with a high GVW. Take a little from a (turbo) and b (traditional exhaust) and mix thorougly, what might the possibilities be, all this was about.


Would it be logical to just instant a freakin turbo, likely. Would it be rational to install a large OE muffler designed for a larger HP engine, sure. This was just hypothetical and a curiosity, if a muffler with internal moving parts had ever been conceived, as Im sure all possibilities have been explored by someone.


Come on folks, you know Im ocd as hell, so lay off the responses, you know Ill wanna respond, but Im DONE. If you wanna tell me how crazy I am, PM me, we might talk. If you dont get it, you dont get it, if that is my fault, so be it, if its yours for making assumptions, what can ya do?

I think the aero / turbine exhaust used to have Rusty Wallace as a spokesman. I know nothing about the performance advantages.

I don't think you are crazy, I was just giving my views on the enterprise. The purpose of forums is to talk, so that is what I was doing. Besides the constant blockage of exhaust flow and induced turbulence, the high heat of the exhaust would make spinning parts impractical without a cooling mechanism or a large mass to limit corrosion. This is why I think it would not work well. Don't get worked up because people don't always agree with you.

I'm bored here at work, so I can speculate and hypothesize as well as anybody. Just because I work in a practical way does not mean that I don't think about alternatives before choosing a course. If I wanted the tried and true way, I would yank the 200 and put a 302 in my car instead of spending so much time and money on the six. The muffler was an interesting thought experiment, but confusion over your aims and considerations over physics and reality spawned some of these responses. If I think a concept is not a good idea, I'm not going to say that it is. Alternatively, if I think it is a good idea, I am not shy in saying so. I don't see how that is hypocritical at all, seems like you just wanted a dig at me. Forgive me if I do not respond in kind.

NASCAR drivers and most celebs, driver or not, would pimp for the devil.
Look at some of the things they peddle. ie teflon oil additives you know the ones with the DuPont disclaimer. Then there is the additive that will reduce wear tolerance, engine needs a 0.040" os pistons and a .010/ .010 crank, but one treatment of wonderous, fantastic, unbelieveable "TURBO SUPER GOO" with lazer sharp teflon in the titanium plastic bottle------

Hey if they say it is unbelieveable---don't believe it!

They have only one consideration, do no harm (no law suits) does not matter if if it does no good.

Titanium this and titanium that and it is not even made of any metal known to man.
Turbo this and turbo that and it doesn't have an intake and the only exhaust is the hot air of ad hype.
Laser or is it lazer, wife bought me a lazer razor but afraid to use it, don't want to do a Vincent

Sorry went off on a tangent ----- now if I could just find that Fisch carb, I know it is here so where, Oh! there it is next to the Brown gas generator-----

 

[66 Fastback]

Like I said, I know nothing of the performance advantages of this mufffler, but I do dabble in fluid mechanics. From their hype, I should be able eliminate some gas compressors out in the field. Seems to me if I strung a bunch of these things along a pipeline they would "suck the gas through it". All I need is enough pressure to reach the first turbo contraption and then those things would take care of transporting it down the line from there. Think of the savings in compression costs

There goes that whole First Law/Second Law thing again.

 

[Thad]

:deadhorse:

And as far as it sounding like a turbo on boost rather than the exhaust side says alot about ricers.

Hey, they don't know if it's blowing or sucking.

 

[mutt]

Harley owners can be....um, more gullible than your average gearhead, especially where exhaust & intake systems are involved.
I keep a straight face most of the time, but I swear ill fall off my bike laffin if i EVER see one of these setups. They SPIN!!!!!

TAILGUNNER EXHAUST

At $795 a set, don't want to buy, want to sell. :roll:

 

[TCIC 300ci superbeast]

well what about a Venturi type things. a long pipe with some holes at the bottom. the air rushing in thought the top suck in air at the bottom.
this is in reply to the aero turbine. this wont add a lot of air but more then the motor could suck in with out it.
i know this work in reverse. playing with the safety air hole tips on our air guns at work. :

 

[AZstang66]

It requires energy to make something move; this energy MUST come from someplace, in this case it will have to be taken from the exhaust gases. This ABSOLUTELY MUST result in the gases slowing down.

sure, we cant forget that most mufflers inhibit exhaust flow, not encourage.

now if you think outside fo an assumption and imagine this moving object(s) as not having tight tolerances to the wall of the ?? housing, then the force would be decreases if not minimal, with appropriate design. with each turn, each new vane or "paddle", would or I would think, reflect a certain amount of sound ??.

thinking outside of the box.

If you correctly install/create a nozzle before the said 'turbine', you CAN actually spin the turbine with no loss in the fluid velocity. Although work will be lost from spinning the turbine, the velocity of the fluid can be calculated and designed to remain the same. Additionally, if the turbine was designed correctly, it could actually reduce the 'back pressure' (static pressure at the turbine inlet) and increase the fluid velocity. I don't see how compressing the exhuast gases by means of a turbine would be beneficial though (unless it sounded different).

I doubt however, that this 'aero turbine' does any of the above; it sounds to me like the marketing people are trying to be engineers.
I mean come on... "thermaldynamics" and "airfoil cone"?? I couldn't help but laugh out loud.
