The HEMI

This is an interesting article. I've heard the HEMI Magnum is a beast,
I would love to get my hands on one of those.

HEMI's HOT! - Chrysler Finds Winning Formula
AUBURN HILLS, Mich., Dec. 9, 2004; The HEMI(R) continues to build
momentum. Since first introducing the all-new 5.7-liter HEMI V-8 engine
for the 2003 model year, Chrysler Group has sold more than 300,000
vehicles with a HEMI inside. In Chrysler Group vehicles where HEMI is
offered, the take-rate is 46 percent.

"The HEMI continues to resonate with consumers and has essentially
become a brand within our brands," said Eric Ridenour, Executive Vice
President, Product Development, Chrysler Group. "And with MDS, our
modern cylinder deactivation system, the HEMI seamlessly moves from
eight cylinders to four cylinders and back. The only thing customers
notice is a savings in fuel economy of up to 20 percent."

On a product-by-product basis, the HEMI remains a popular engine
choice. For Dodge Durango, the take-rate is 54 percent. The 2005 Dodge
Ram is at 46 percent while Dodge Magnum and Chrysler 300C are at 43
percent. Jeep(R) Grand Cherokee's take-rate is 29 percent. MDS is
available on Dodge Magnum, Chrysler 300C and Jeep Grand Cherokee.

In the spring of 2005, Chrysler Group will up the ante and unleash an
all-new, beefed-up 6.1-liter 425-horsepower HEMI V-8 engine in the new
2005 Chrysler 300C SRT8. Preliminary performance targets for Chrysler
300C SRT8 are 0-60 mph in the low five-second range and a quarter-mile
time in the high 13-second range.

The 425-horsepower, naturally aspirated 6.1-liter HEMI will be the
highest specific-output V-8 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.

"Without question, the HEMI continues to play a critical role in
building momentum for the Chrysler Group," said Ridenour. "With the
introduction of the 6.1-liter HEMI, we're taking the legendary HEMI to
a new level of benchmark performance."

Chrysler Group builds HEMI engines at its Saltillo (Mexico) Engine
Plant. Production for the 6.1-liter HEMI begins in early 2005. Chrysler
Group sales are up three percent year-over-year through November.

Man those stoopid 8 6 4 engines were a failure way back when. You mean
they have brought them back????

Figures Chrysler would try it....

'Hemi' used to actually mean something, too bad.

Don't knock it till you try it...

I've had a hemi Ram 2500 4x4 for one year now. In that year, I've
never had to open it up fully! Them 345 horses do a great job of
moving that truck along without effort. The dual redundant ignition
system adds to reliability (each hole has two plugs, there are eight
coils, each coil fires two different cylinders.

Except for the truck's turning radius (about 125 ft, IMHO) making it
impossible to park in most parking lots, the rig is great.

Too many parts in my opinion.... Wasn't that the last 8 6 4's big
problem? Too many things to screw up.

If they run, then great, but if they fail, you need to mortgage the
house to fix them....

The GM 8-6-4's problem was GM. They produce garbage and were even worse in
the late 70s to early 80s. My guess is that Chrysler alone wouln't have
attempted it, rather the Daimler-Benz people are trying to maintain their
reputation for being engineering leaders. I've seen some docs on the web
and the new system is more sophisticated, but no, I'm not going to buy one
until they've been proven.

I think we've come a long way since that previous POS... <g>

That said, I don't think all Hemi's have the cylinder shutdown, I'm
not sure mine does... I was mainly trying to say that the engine
overall was a winner.

I'll have to find out when the MDS (multi-displacement system) was
first available...

2005 model years. Not even an option in Rams...

Takes care of that! <g> Thanks for the enlightenment...

So you can get the HEMI in the magnum but not the 2005 ram?

I think he meant the deactivating cylinders option. The hemi has been
available in the Ram trucks for a couple of years.

In fact, the only engine options in the 2500 and 3500, 2004 models
were the Hemi, and the diesel. (Not much of a choice!) The intresting
thing is that the diesel is been so refined that it is (almost)
competitive with the Hemi in driving fun. But... Much more expensive.

I've got diesel trucks, I've got the Hemi, and I like 'em all.

Yes.

From what I understand they've got 3 setups for the new "Hemi":

1. Truck (basic, 2 plugs per cylinder)
2. General purpose auto (4 cylinder fuel saving feature)
3. Performance (more HP, no fuel save)

-John

So you can get the HEMI in the magnum but not the 2005 ram?

As others mentioned, I meant the MDS. The hemi has been in the Ram since 2003.

Unfortunately, I bought a 2002

Fortunately, I'll by a Powerwagon in 2005

I took delivery of a 2005 Jeep Grand cherokee limited w/the HEMI(R) MDS
V8. as far as i know this is an 8 to 4 system.

Problem: Hesitation during exceleration. check engine light on. Dealer
had the truck for 1.5 days and had to call chyrsler engineering. long
story short, check engine light is out but there is still mild
hesitations throughout power application between 1700 and 4000 rpms.
acceleratin is not smooth and has high spots similar to that of a 2
cycle motor cycle engine. I am not pleased. contemplating what to do
next.

Gents: as far as i know the pick-ups are not offered with the MDS
system. Yes theres plenty of HEMI pickups to be had but the gang at
chrysler found the combination of a vehicle that worked with a load on
and the MDS to be not compatable.

Chrysler is finally doing the right thing. Is too bad that the company is
now owned by the Germans. The American management just don't know how to do
it right. It takes the Germans to come in and take over.

Ben

Not sure if it's the same thing, but I've got the Magnum RT with the
hemi and MDS and have noticed a slight delay on acceleration, but this
is only if I've been coasting or driving at a steady speed then nail
it. Likely this is the other 4 cylinders kicking in.

At worst, it's less than a half second though and you do have
acceleration prior to that, just not 340hp worth.
