420HP/420TQ SAE A little higher than I would have guest. I guess that explains the 12.44 ETs

420 rwhp? sounds anout right for a broken in car. probably a bit lower off the showroom. probably 405rwhp. sounds exactly right.


doesnt sound a single hp under rated to me.

420rwhp is maybe 480-485 crank on a broken in motor. no suprise there. still doesnt equal a 12.44 @110.

it is what is it. an old school hemi.

Stock for stock the HEMI sounds a helluva lot better than the 5.0 and especially the LS3, which is so muffled you can hardly tell it's a V8.

I'd be curious to see what it does on an engine dyno. I'm guessing 480-490 given that drivetrain. It was reported on one of the Mopar boards that they had to take out some timing to pass emissions. With headers and some timing it reportedly made 525 at the crank. It's too bad they put it in such a pig. That motor has a ton of potential. I know a local shop who did a max effort porting on those heads and darn near had 400 cfm out of it.

People need to get used to these high weights. Its not going to change. Thank your local government official for that.

In addition you can thank the customers who insist that it has lots of sound deadening and unnecessary electronics and computers. It's a muscle car god damnit, why do people want it to be a luxury car too?

I think they should offer a live axle option on this car... that could knock a few pounds off and make it better at the strip.

420whp is about 500 crank, a good bit more than the rated 470. Pretty sad if it's only trapping 110 with that much power. I think a diet would have been much better than more power for this car.

I'm sure other drivers will be able to extract more out of this car stock.

The people voted for the ones in office. Look towards the root.

Question about "old school hemi"........

The last cutaway I saw of a 5.7 Hemi (2008) it had a wedge piston design and a Hemi head. I was under the impression that "old school hemis" were hemi piston and head design, not just hemi heads. This would lead me to think these new engines are more of a Wedge design than Hemi.

Feel free to correct me here, just curious. Thanks.

That is True, the new "Hemi" was a smart marketing move by Chrysler to bring back the Glory day's Idea to move units.

Slap that in an old beat up Dart or Duster and be done with it.

I think that is pretty awesome considering the weight. Sucks that all the new cars weigh so much with maybe the exception of the 5.0 but even that's a little heavy.
