Looks familiar.....anyone remember the notorious 6.1 HEMI engine pic.


We have seen a 5.7 HEMI 300C go 5.3 0-60 and 18.8@101 in the quarter. Now we gain a hundred pounds and 85hp and 30lbs of tq. This car has been rated at 0=-60 in low 5s, which the 5.7 already does, and quarter in mid 13s. For some reason I think when the magazines get ahold of this car they will be shattering those numbers by big margins.

 

when will this be availible to the public? I know somebody who was looking into buying a 300C, but will probably just sit tight for a while when he sees this.

 

This is what makes a 6.1 different than a 5.7.


The 425-horsepower, normally aspirated 6.1-liter HEMI is the highest specific-output engine ever offered by the Chrysler Group. Its 69.8 horsepower-per-liter rating exceeds even that of the legendary 1966 "Street HEMI." Torque is rated at 420 lb.-ft.

Although the Chrysler HEMI was born in the 1950s and entered into legend in the 1960s and '70s, today's version took much of its inspiration from the original - particularly the namesake hemispherical combustion chambers that provide power and efficiency.

When SRT set out to develop a more powerful HEMI for the Chrysler 300C SRT-8, they were mindful of the engine's heritage, which led to adopting traditional HEMI engine cues, such as an orange-painted cylinder block and black valve covers.

The SRT powertrain engineers who developed the Chrysler 300C SRT-8's engine achieved more horsepower by adding more cubic inches, increasing the compression ratio, redesigning the cylinder head intake and exhaust systems for increased flow, and increasing engine speed.

To get more displacement, SRT engineers bored out the diameter of the cylinders in the Chrysler 300C SRT-8's HEMI by 3.5 millimeters each, to increase the total displacement to 6.1 liters from 5.7 liters. Compression ratio was also increased to 10.3:1 from 9.6:1, unleashing more energy in the combustion process.

Engine breathing was increased with new high-flow cylinder heads, a specially designed intake manifold, and exhaust "headers" with individual tubes encased in a stainless steel shell, all unique to the 2005 Chrysler 300C SRT-8's 6.1-liter HEMI engine. Larger diameter valves and reshaped cylinder ports in the heads allow for maximized air flow. The intake manifold was designed with larger diameter runners for higher-speed tuning. Exhaust is routed through a larger-diameter (2.75-inch vs. 2.5-inch) exhaust system with 3.5-inch chrome tips.

Performance-oriented camshaft profiles were developed to balance total vehicle requirements, simultaneously allowing more air in and out of cylinders. This increases performance and manages a higher engine speed, which is another method to increase horsepower. SRT engineers increased the HEMI's peak engine speed nearly 15 percent, to 6,200 revolutions power minute (rpm) from 5,400 rpm. Intake and exhaust valve stems are hollow, and the exhaust valve stems are filled with sodium to help dissipate heat more efficiently.

The high-performance 6.1-liter HEMI is further strengthened with a host of redesigned components, including a reinforced engine block with increased coolant flow, forged steel crankshaft, high-strength powdered-metal connecting rods, floating-pin pistons (cooled by oil squirters), and an oil pan modified for reduced oil foaming.

The 6.1-liter HEMI's power is channeled through an A580 five-speed automatic transmission with specially calibrated AutoStick® driver-selectable range control, which offers fully automatic or manual shifting selection. A heavy-duty four-flange prop shaft sends the torque from the transmission to an upgraded differential and axles.

 

Theres a few visual differences with the CTSv, mostly just the grill But still...you can tell the difference between a v and a CTS on the road pretty easily. Probably unlike the SRT-8.

 

I don't know if I'm getting the whole reason behind muscle-sedans. Why not save that for the intended purpose musclecars? Who needs a 425HP 4-door sedan, and why? To roll around in and say bling bling? It's getting a little ridiculous. Sedans now that can beat L98's, LT1's, (even with a few mods) and give LS1's a really, matter of fact, way too good of a run for their money.

I mean LB9 M5 and L98 A4 G92's, LT1's, LS1's etc. are fast cars to just drive on the street and are quicker than 90% or more of the cars you'll be with on the road at any given time each day. Low 13's-low 14's/5-6sec 0-60's is not particularly slow. These new cars with all this power stock is pretty crazy. But put it in the right cars at least!

 

Maybe......

Someone like me.


Why? I love to drive great performing cars....and sometimes I need to carry people in them.

 

I would love for a LS2 powerd, RWD, 6spd Grand Prix.
If I had 50k, I would probably get a CTS-V as well. I think its pretty cool, thoes muscle sedans. It seems that the only RWD cars anymore are sedans or trucks, so we have to start somewhere.

 

I would rather have a 300C SRT-8 Coupe, but as I said before in another thread. Sometimes people need the practiacality of a sedan or wagon. Just because I have to have 4 doors or cary a big dumb, deff dog around doesnt mean I should be limited to driving a a slow unresponsive car.

Still no word on a SRT-8 Magnum? I could care less about a 4 door Charger. Id take the 300 C 4 door over a less optioned oversyled Dodge. we could really use a Car like a SRT-8 Magnum.

 

Patcience, 5 new LX based models will be in production next year. Including the Charger, SRT8 of said Charger(should have a manual), and SRT8 Magnum. Things will start to get good about the time of the Detroit Auto Show. There is a possibility of a coupe coming next year.

 

Saw the 300 SRT-8 at Pebble Beach Saturday. If anyone is basing their excitement level on a bunch of tacked on add ons, you won't be interested in this car. On the other hand, if you had a thing for Thunderbird SCs, or 90s era Impala SSs when those cars hit the street, then this is going to be something you'll want to look into.

In fact, this car IS the modern Impala SS of the 90s. It's big, it's very quick, distinctly American, & even the price level is dead on (anyone who thinks mid 90s Impala SSs were cheap, affordable, or reasonably priced when they were out gets an "F" for the day ).

Unfortunately, the coupe market isn't what it used to be. WE may be coupe & performance enthusiasts, but we are only a very small fragment of the automotive market. Other than the Mustang, there isn't a rear drive coupe on the planet with a V8 going for under 30 grand. Even the GTO that everyone says is too expensive, is the 2nd cheapest V8 coupe on the planet.

 

You could ask who needs a 425HP 2-door car??? 2-door cars arn't allows the most practical for carrying people/cargo, so put that fun engine in a practical car or truck and you have the best of both worlds.

 

You are not alone...

 

I'm aware of the fact that DCX has built a couple of great cars in the 300 and Magnum, but to be honest, these cars would not have gotten one-tenth of the buzz if they named their pushrod engine something other than 'Hemi.'
Simply saying the word 100 times in commercials and articles has had the desired subliminal effect on the car-buying populace...am I correct in understanding that the new hemi isn't even a "true" hemi??

And I saw the other story posted about an interview with and engy from GM...he said the new hemi is almost a carbon copy of the LSx engines...doesn't that mean lawsuit or something?

 

That carbon copy comment is just wrong.

Deep skirt blocks, cross-bolted main caps have been done before the LSx family of motors. The old SBC and SB Mopars haver more in common than the new hemi and LSx motors. The heads are completely different, the block is a lot different. The block has more in common with the outgoing 5.9s than the the LSX. Other than the intake I dont really see that much in common. They are bothe Pushrod motors.

 

man that things tryin to look like a bently
