I dunno if anybody has been reading the car mags lately, but the new 392 Hemi is showing up everywhere. Hot Rod's July issue did a dyno of the new crate engine...she made 560hp at the crank! As an SRT-8 owner, I sure hope that Mopar Performance releases a stroker kit for the 6.1L!

Whoops! I just realized I posted this under the wrong section! LoL I guess the redesign of the site threw me off on this one.

 

its supposed to be one bad *** engine..i look forward to seeing what dodge does with it, but i cant see it showing up in a car until they beef up the viper..

 

They threw one of those 392s into an older challenger. heres a link about it. I remember seeing this at the auto show. I wish they would have popped the hood but o'well.

 

Oh, I'm not talking about DCX offering the 392 Hemi in the SRT-8s STOCK. No No No- I'm talking about it in terms of an aftermarket kit! Apparentally the only proclaimed difference between the 6.1L and the 6.4L engine that was first displayed at the SEMA show are: the heads (CNC ported with beehive competition springs), stroker crank, and 50 mm throttle body (might have a ported manifold, bigger injectors, and a higher-lift cam, but that's just speculation on my part).

If you ask me (which you haven't), it would be extraordinarily easy for Mopar Performance to throw a 392ci stroker kit together for the SRT-8s. I'm willing to bet that the cost of all the parts combined (all the parts we know about, anyhow) would be around $3000 USD. In simpler terms, you'd be getting a horsepower-making monster for less than half the price of a Hennessey SRT-550 but with more power! It boggles my mind as to what kind of power it might make if one were to add alittle forced induction to the equation!

Three words for everyone: SIGN ME UP

 

well, i cant imagine that DCX would go to the trouble of making this monster engine, and showing it off all over the place, if they didnt have some plans for it...and i cannot see a crate motor being the only plans.

With hemi design being added to bigger and bigger motors, I like to see a hemi go backward and see them in some of their smaller motor's like V6's and even I-4's! Wonder how much power a 2.4l hemi DVVT engine would make with no induction?

 

i think that technically, the neon motors were somewhat of a hemispherical design...

 

They can't have too much of a hemispherical design because they are a 16-valve i-4. That's 4 valves per cylinder and you can't acheive that with a HEMI. You can achieve that, however, with a pentagon, sort of design where instead of it making a hemisphere, it makes sort of a triangular shape. Im going to go look up the link on this and then post it.
http://auto.howstuffworks.com/hemi.htm Here's the link explaining it. It's called a pentroof design. I'm surprised no other automobile maker has put a patent on that yet so they could have a motor that would come closer to competing with the HEMI (but it will still be no match, im just saying they would be closer and more efficient than probably what they have now) . (scroll to the near bottom and the pentroof design will be explained.)

 

I do believe that all the engines used in the Neon were of the pentroof head design. This design is practically a kissing cousin to the Hemi as you can see in this photo: http://www.sportcompactcarweb.com/pr.../photo_13.html

The only real difference between the pentroof and the hemi design is that the top of the combustion chamber is angled (pented) instead of being hemispherical. The valve and sparkplug arrangement are virtually identical!

 

it is similar ot the hemi head...alot of people refer to the neon engines as "semi hemis"...alot of modern heads use a design similar to that of the hemi head, with a somewhat hemispherical combustion chamber, with the valves surrounding the spark plug which is centered in the combustion chamber
