The 6.4 would weigh about the same as the 6.1 it replaces. Adding displacement doesn't really add weight to an engine. Could even be lighter, if they replace the iron block with aluminum. And the weight gain from the 8 speed will probably be closer to 25 lbs, not 250. Beyond that ... there isn't really anything that could add weight.

I totally forgot about the iron block! There's another 100 pounds probably!

I understand what your saying BUT let's compare Apples to Apples, 2SS against SRT8 and see what the price difference is!

Read my post, that is what I did.......

Should be all Aluminum I believe as it is based on the newer 5.7 and not the older 6.1. Also it is getting electric power steering which should save a few pounds as well as reduce power loss to the rear wheels

No, it would reduce power loss to the flywheel. And all accessories are accounted for under SAE net testing anyway, so there isn't going to be any 'hidden' power gain from it. It just contributes to its 480ish rated output.

there will be virtually no weight gain as the new 6.4 is based off of the 5.7 v8 not the 6.1.

It will need to be compared to the gt500 because of it's new added hp putting it past the SS in straight line performance.

2011 Dodge Challenger SRT8 to get 480 HP?

First and foremost among the predicted changes on the 2011 Dodge Challenger SRT-8 is more power from an enlarged 6.4-liter Hemi: a bump of 55 horsepower and 40 pound-feet of torque. That would put the big coupe at 480 ponies and 460 lb-ft., and rumor also has it that power will get to the wheels through an eight-speed automatic transmission developed by Chrysler and ZF. Also according to Allpar's inside man, output levels will remain the same on the R/T model, while the base SE will get Pentastar V6 engines with 40 more horses and 20 more lb-ft, for 290 hp and 270 lb-ft. in total.

Most of the other supposed changes seem meant to make life easier for Chrysler and Challenger buyers. The floorpan is being reworked so the car fits more easily into Charger and 300 production, an electric power steering pump is coming onboard and an upgraded interior is in the offing. Cosmetically, the muscle car picks up the Charger's door handles, the Magnum wagon's hatch release button for its trunk, and the lower front grille gets turned upside down.

More displacement doesn't mean it will be physically larger. I wouldn't expect weight to rise much, if any.

Dodge is still missing the boat in comparison with the GT500. The 2011 GT500 is rated at 550HP, is lighter, and will run circles around the 6.4/8 speed auto if this is indeed what is to be released.

IMO what should have happened:

• R/T gets the 6.1 from the outgoing SRT8; 5.7 is dropped; price remains the same.
• SRT8 gets a 6.4 525+HP motor and improved suspension to compete with the GT500 and Z/28. Pricing is in-line with the GT500 and Z/28.

Dodge is really shooting themselves in the foot by focusing their upgrades on the the SE and SRT-8. The R/T attracts the most interest, but is underpowered so most enthusiasts don't give it a second glance. If it had 400-hp on paper with an upgraded interior, I think it could give GM and Ford a run for their money.

It's a real shame too. The Chally has some of the sexiest lines of any recent production car from any major automotive manufacturer. It's sad that Dodge doesn't seem to want to be as invested in the pony wars as much as Ford and GM.

Those were literally my exact thoughts.

if i recall correctly the 5.7 is actually a newer more sophisticated motor than the 6.1 and that the 6.4 is actually being developed off of that. and without putting my entire foot in my mouth i will attempt to say the 5.7 is being held back by the 6.1 since it is not allowed to step on big brother's toes.
