yup its gonna hit the chargers for 09 or 10
it hasnt been confirmed yet though

 

how are they doin that, tune? and thats crank right?

 

For starters I think they went to variable valve timing, and I believe the heads were revised. Fuel economy went up also.

 

Advertised HP is always crank

 

I'd suspect they are going to direct injection, but don't know that as fact.

 

The picture of the engine, show the injectors in the same location. I do not know if they are using the correct photo though....

I've read that it's the variable valve timing that's giving it most of the horsepower and fuel efficiency gain.

 

I have no clue what variable valve timing is.

But I read that also. :yes:

What happend to the hemi being discontinued in the chargers?

 

I don't think the new CAFE Standards are effective until 2010. Those will likely kill the HEMI.

 

Here is the reason for the power increase:
2009 Ram:
"Towing is estimated at 9100 pounds, thanks to a revised 5.7-liter Hemi V-8, now with 380 horsepower and 404 pound-feet on tap, up from 345 horsepower and 375 pound-feet. Its cylinder-deactivation capability remains (called MDS), while significant changes include variable valve timing, a bump in compression ratio, and a two-stage intake system that switches between long and short runners for power or torque."

"The Hemi’s claimed extra refinement comes from better airflow management in the enhanced intake and a first-ever factory dual-exhaust system. The upshot is a four-percent improvement in gas mileage, partly from the ability to use the cylinder deactivation more often, partly from the variable valve timing and improved aerodynamics."

It's not VVT, it's VCT, variable cam timing. The gains are from VCT, higher compression, and a few other things. You can read about it here: http://www.allpar.com/mopar/new-mopar-hemi.html

It's supposed to come to the Charger and 300 in 2009, possibly, along with the Challenger. Might see a 6-speed manual option for all of them too.

 

i dont really see what the difference is if people call it variable cam timing or variable valve timing, the cam controls the valves so calling it either one still makes sense.
Hopefully now, all those jokes domestic car owners make about Honda and their VTEC can be laid to rest, i cringe when i hear a fellow V8 domestic car owner make an ass out of himself.

 

Wow, someone posts a picture of a blown Chevy big block and nobody flipped out. Color me surprised.

 

I'm even more surprised at all the hoopla over an 8-9% power bump.

*shrug*

 

I can't believe you can't say p u s s y footing. I wonder if you can say ****er spaniel?

edit: apparently not.

 

How about the guys that swap in a different cam and a set of heads and they dyno about 40 RWHP more than before .... and that's with no VCT or VVT or V-whatever-T .... I guess they lose some fuel economy ? that's the only pro to using VCT versus better heads/cam combo?

 

It's gonna be interesting to see how the the various vendors in the cam business are going to adapt to the changes.

When they do figure out how to adapt to the new hardware we are gonna see even some good gains from a cam swap.

 

well if you must know vtec stands for VERY TALL ENGINE COOLER

HAHAHAHAHA OMG THAT IS UNREAL LOL

 

well damn thats kinda ***. I guess its ok tho, because im sure the msrp of the car will go up.

 

I look at it like the different types of supercharging. Each has their advantages and dis but it is all supercharging.

 

It's a 100% definite for the '09 Charger R/T. Info about the new 5.7 Hemi going into the 2009 LX models was posted almost a year ago (last April) in a "2009 models" thread on the 300Cforums site. All Chrysler/Dodge/Jeep models with the current 5.7 will get the new gen II Hemi for 2009.

 

I dont think the 5.7 has been underrated at all. 350 rated for 280ish at the wheels. 380 should net about around 300, maybe some more, but not too much. The SRT is the "underrated" one, since its rated at only 75 more, but dynos 90whp more on average.

The 6.1 appears to be underrated becuase they (SRT) test under much harsher conditions than the normal engine guys do.

 

+~20 at the wheels, a few % improvement in mpg, smoother running, no complaints here.

 

(yeah, baby, I'm a prophet of horsepower)

 

So perhaps the 6.1 is probably closer to 450 crank HP

The GM guy had the idea a couple of days ago

They can make small changes to the engine and up the rating to 440 or 450HP for marketing reasons.

 

why is that when the 6.1 dyno's in at about 360rwhp? since we do not know the efficiency of the SRT8 tranny, do you have any engine dyno #'s to back your arguement?
