However, the design is an old design, and not good for emissions. As you said "with new laws comes new technology". ooooo, ok so what's the secret dodge did to improve emissions? The current hemi magnum uses TWO spark plugs per cylinder to ensure thorough combustion, rather than one. Yeah. Big technology jump there....
Now, your argument is that it outperforms "our" cars (or engines in this case) and that it's not outdated.
When in fact, it's the other way around. Compared to modern engines such as in hondas and toyotas, imports and other more modern engines use a design that is WAY more efficient than the hemi. It's called a Pent Roof combustion chamber. The pent roof combustion chamber also allows for FOUR valves per cyclinder. A Hemi can only have TWO. So better air flow and mixture is accomplished in a pent roof design over the hemi design. On top of that, because of the shape and size of the pent roof, it has less heat loss and more efficient burning than the hemi.
So. Cliff notes:
You have no idea WTF you are talking about. And the "hemi" at this point is nothing more than a marketing ploy.

wow u do know what u are talking about, i'll give u that, however i didn't once say anythign about how the hemi worked and what it did yet u automatically tried to say i didn't...I didn't say the hemi outperformed. I never once said anything to down play your engine at all nor did i try. I commented on how u think urs is better. Weird how someone who obviously has knowledge on vehicles can be a big *** at the same time...mechanics must have taken the place as civil conversation in your brain. O well if i have a problem i'll be sure to ask. Get a life buddy.

You posted like an ***, so you got a likewise response.

Rep Power: 399 well then they say the srt4 isn't going away. the engine might not go away, but the neon srt4 is.
so no more turbocrap neon.

Lets not plays games here. You use your vast car knowledge to prove whatever you wish, but when it comes down to it Japan doesn't have a motor with as much displacement as the 5.7L hemi for the cost. And as the adage goes, "there's no replacement for displacement." You right that down.
back when it was first invented, yes the hemi was a great revolutionary design.
but not anymore. today it's nothing but a marketing ploy. and you talk about the 375lb/ft of the hemi vs an import. ok then compare it with another torque monster. the Z06/LS6 corvette uses pentroof combustion chambers. So does the mustang GT. in fact, pretty much every car on the market, regardless of it being a high revving import, or a torque-gushing domestic has a pent roof design. the hemi is now nothing more than a marketing ploy, and a relic when compared to the pent roof combustion chamber.
in fact, did you realize that even the new hemi is not even an actual hemispherical head any more? lol. it's actually what they call a "WEDGE" or pentroof hemi design. because of how inefficient and so far behind the hemispherical head is compared to today's pentroof design, dodge engineers had to take the shape and make it a WEDGE and adapt some of the pent roof technology to get it to work right.

your proctologist called. they found your head.

Granted, you have a vast array of car knowledge; however, we seem to be having trouble staying on topic. Lets get in the Dalorean with Doc and take a trip back. . . .I don't recall ever mentioning the chevrolet LS6 or the Ford 6.8L V-8 for the '05 'stang. These two power plants should be honored to be regarded as chrysler hemi competition. You stated in one of your previous replies that the high rpm, low displacement honda motor is better than the new 5.7L hemi design (and you're right, its not a hemi - but its a design unique to chrysler products none the less). I rebuttalled the hemi far outperforms the japan low displacement motors. Its not hemi vs. the world, its hemi vs. import. Don't add other aspects to the arguement. Big Daddy Don Garlits, a legend in racing, stated the new hemi looks and performs well, and his car knowledge far excedes your's and mine. Futhermore, Ford developed a hemispherical head, and as did Porsche. If the American and German powerhouses invested money into the design, it can't be that inefficient and pre-historic. On the contrary, you have no idea what you are talking about.

Compared to modern engines such as in hondas and toyotas, imports and other more modern engines use a design that is WAY more efficient than the hemi. It's called a Pent Roof combustion chamber.
And if you want to discuss which is more efficient at producing power, guess what? The S2000 F20C makes 76.5 lb/ft of torque per liter. The hemi, with it's less efficient design, only makes about 66 lb/ft of torque per liter. In other words, the hemi is the less efficient design.
And the vette and stang should be "honored" as competition for the hemi design?
My little friend, you need to seriuosly educate yourself, because you're just plain wrong. The hemi is nothing more than a marketing ploy. As I already said, the hemi doesn't even work. lol. They had to change the head from hemispherical to the more modern pent roof adaptation used in modern engines today. In fact, the ONLY thing the new "hemi" even has in relation to being an actual hemispherical engine is the 2 valves per cylinder. Otherwise, it's a pent roof design all the way.

I'm showing you the proof, the technical aspects, the literature, and the information regarding the fact that the hemi is nothing more than a marketing scheme. You're now backpedaling after I showed you how wrong you were when you said "the hemi is not a marketing scheme and it's a great design and blah blah blah". You're backpedaling and now trying to say it's better than the imports, which in terms of efficiency, it's not. And the vette is proof. If you take the same technology of the vette with pent roof, it makes even MORE torque/liter than the hemi.
I'm trying to tell you the earth is round, and you're trying to argue it's a triangle.
