well, thats sort of what i ment, in that it's a great engine but dodge is just throwing it in every damn car they can stuff it into in order to slap that badge on the cars and up the cost by like 10 grand. i'm a little supprised they havent offered it in a neon/caliber package the way they've been doin things, it'd be like ford trying to stick a gt engine in every vehicle car they sell, it may sound cool, but it's not exactly practical

then new "hemi" is not actually a hemispherical combustion chamber like the real hemis were, so yes it is a gimmick, and that thang don't got a hemi.

 

sure, but none of that keeps them from constantly heading to the shop for this and that.

 

Sogofast, what makes you the expert on combustion chambers.
I'll attach a link and you explain to all of us what makes a hemi a hemi.

Thanks

nothing inparticular makes me an expert on combustion chambers. I'll explain it for you though, since the link you posted has most of what you need to see the difference.

the first picture is a hemispherical combustion chamber. you can tell this, because it's round. Notice, that it is round, completely round and shaped like a hemisphere.



This is the picture from your link that shows the combustion chamber in the new "hemi". It is round-ish, but not completely round. That makes it a polyspherical combustion chamber. It's not something that is new by any sorts, as chrysler has been doing it I think since the '50s. The reason then for making the poly chamber, was cost savings.



You can read more about it on wikipedia, they have a pretty good explanation of it there.

it lost to the toyota tacoma in a tug a war.
In other news my one uncle swears by dodge, hes had 3, bought 2 of them new and one of them used.
Hes got a 1500 4x4 it gets crap gas mileage, but its reliable.

 

Most importantly the valve are opposed and does not shroud the air flow. When a valve opens up into the middle of a bore air flows completely around it.
On engines with all the valves in one straight row. Air flow near the cylinder walls does not flow as well.

The reason for the slight shape difference between new and old Dodge Hemi is compression ratio.

The 426 did it with monster domed pistons. The new gen Hemi had to reduce the combustion chamber volume to achieve the compression ratio without using moster domes.
