Look what came out of my intake...

"hemi"...

...from my escort.

hemis have crap chamber swirl, which is why theyve always had trouble passing emissions (after emissions were introduced, that is), get poor mileage, and arent produced anymore. theyve been ditched for far more efficient head designs that increase combustion chamber swirl:

...and others.

I like the idea idea of putting them diesel exhaust stacks, that'd be really neat having swirly exhaust....

Yeh I cannot imagine the Tornado would do much good. Putting them in the exhaust of a diesel would be pretty neat though!

Even the new Hemi, isn't a true Hemi like the old ones.

 

[Wicked_Sludge]

nope. the new hemi is little more than just a name.

 

[MAKG]

note that im not saying they DONT work. im just saying that if they do, the improvement is immeasurable on a street driven vehicle.

Could you kindly share the difference?

An unmeasurable difference is EXACTLY equivalent to no difference. If it isn't possible to show them to work somehow, they don't.

 

[Wicked_Sludge]

mileage on street driven vehicles varys normally. if this was a test track vehicle that was always driven with the same load, under the same conditions, down the same peice of track...who knows? maybe there would be a measureable improvement of a fraction of a MPG. i cant say it wouldnt because i havnt tried it.

all i know is that my mileage limits havnt changed since installing that gizmo.

 

[Mechanickid]

forgot but what makes a hemi a hemi? Skewl me .

 

[Wicked_Sludge]

hemispherical combustion chambers. see my first pic.

Chrysler had to quit making the Hemi back in '72' I believe. Part of the new EPA regulations required any motor to maintain it's emissions for at least 50k miles. I had a D-50 with the Hemi motor but it was only a 4-banger with three valves.
Back to what was in the intake. I was at the Jeep dealer on time and the service guy was showing some women what he had gotten out of her intake. It was half of a floor mop that some mouse had taken up there to make a home.

My brother had a air filter canister on a 6 month old Explorer full of dog food, he was surprised it even ran. It came in for an oil change and he happened to check it while it was draining or else nobody would have known about it.

 

[Wicked_Sludge]

after moving down to washington (not much of a rat or mouse problem up in alaska), i got to see all kinds of neat mouse homes built in air filter boxes. youd be surprised what a vehicle with still run with stuffed in the intake.

A friend put one in his Dakota for better mileage.
He took it out after 2 months when he found he had worse fuel mileage.

 

[ehayes928]

It is just swirling the intake air, and if it is a restriction, it would increase the velocity of the intake air and encourage complete mixture of the fuel and air. (I'm talking about carbed and Throttle body engines)

Well, if you want proof it's not a gimmick go to basically any forced induction section of any serious forum and ask if it's a good idea. I may say whatever popular mechnics tested may be crap, because F1 people spend hundreds on these kits. But they do indeed cool the charge, allow for leaner burn conditions, more ignition advance, and suppress knock.

The Turbonator works, do you get the efficiency claims they make? That's for a whole nother thread!

Hey, this is a link to the wall Street Journal, specifically pointing out the EPA and FTC have tested these "vortex" "turbonator" whatevers, they dont work. End of debate i guess.

 

[OilPatch197]

What do you mean by "they don't work"?

Turbonators work, they simply swirl the airflow at the carb, it is the overinflated claim the devices make is what we are discussing, which I reckon would be very dependant on the vehicle, the condition of that vehicle and driving habits.
