i have been wondering something how is it that dodge can make 390 hp 410 ft lb torque and
chevy-6.2 liter vortec 403 hp 417 ft lb torque
ford- 6.2 liter 411 hp 434 ft lb torque
toyota- 5.7 liter 381 hp 401 ft lb torque
nissan-5.6 liter 317 hp 385 ft lb torque

so how is it that for ford and chevy to make just a little more power they have to have an engine that has .5 liter of displacement on dodge

 

our hemi has more technology in it than fords or chevys big motors. Ours has variable cam timing and a short/long runner intake.

 

It is probably due to the Hemi head configuration.

 

All of those engines look pretty impressive when compared to my 1979 Z28.

180hp!

 

You can not look at CID and say it should have x more or less HP. Look at the little 4 and 6 bangers making 300+ HP.

The same CID Hemi made 345HP prior to 09. And there is plenty more to be had with the 5.7 down the line.

 

get rid of emissions requirements, and you could easily pull a few more just off having a free-er flowing exhaust (no cats, no resonator, performance muffler).

 

true agreed the technology has taken dodge along way with the new hemi configuration and also agreed displacement doesnt mean hp but i could see with a few changes ford and chevy with the bigger displacement becoming a powerhouse with the bigger engines. would i be correct in that statement.

 

With lots of money, you can make anything have more power, hemi or not, all are capable of a little more HP/TQ.
But i see the biggest advantage with a hemi, you can add more power to it cheaper than you can with a ford or chevy.
The potential is there, but more for the hemi, than any other engine. The hemi is a stronger design over the others as well.
Also, take into concideration, ford & chevy engines are pretty much maxed out, the hemi can withstand alot more HP/TQ by far.

 

My Charger 5.7 is N/A on a stock rotating assembly, and a Pre-Eagle setup as well, although I plan on changing that soon. Anyways my stock numbers were pushing 293 rwhp (Can't recall rwtq).

I completely striped out anything emissions, 02's, ERG Valve (blocked off), Cats, etc...

CAI, 180 T-stat, 87mm TB, 6.1 ported intake manifold, 268 XFI Cam, 6.1 rods/springs, Mopars Heads, Mopar High-Flow Cats, Custom Exhaust, and still running Pre-Eagle stock heads. After a CMR tune I'm sitting around 412 rwhp and 426 rwtq, as of September of this year. These motors do have huge potential, especially the couple years, back in 05-06 there was very little on the market, hell the JET Chip was a big deal then, now really not even looked upon.

 

And.....

Those numbers are with a 19-20% tranny loss, so it's pretty close to 500 at the motor.
