Chrysler 300C

Isn't it interesting that Chrysler's advertising tries to take advantage of the old "hemi" mystique while the best engines now use flat or nearly flat combustion chambers (literbikes and F1 cars)? I'm amazed at how many pseudo-technical males puff their chests out and get a slightly glazed look to their eyes when they say the word "hemi". They buy it hook, line and sinker.

Give me a break.

No offense intended to Hemi owners, I know they are the best and most powerful cars and absolutely reek testosterone and chest hair......

 

Indeed, the reason the hemi worked well (back then) was that the exhaust vavle was on the "other" side of the head and thereby, the exhaust gasses has easier egress into the header. This allowed the intake and exhaust ports to have "better" shapes (e.g. fewer turns more rounded profile). It had nothing to do with the shape of the combustion chamber!

Note the F355 and 360 engines have a pyrimidal arrangement of valves. The outer 2 intake valves are angled towards each other (4.8 degrees?) as well as being pointed towards a common point with the exhaust valves.

F1 engines have a true pyrimidal arrangement of valves where each valve points towaards the center of the cylinder bore. The current art is around 22 degrees of angulation between opposite vavles--e.g. a rather flat chamber shape.

neat package for the price though...but that name "chrysler" still bugs me...

 

I had a previous generation 300M. Drove it 65k miles in 18 months for work without any maintenance except new tires and a bent rim. I will definitely get the new on when the get the AWD into production for about a year. Big power, large sedan and loaded for 1/2 the cost of a 3 yr old 7 series bimmer. I think everyone still has the 80's mentality regarding US quality. Toss out the Geo's and all that junk and the cars do well. Go to an Audi, Bimmer forum on the web and owners complain about blown engine gaskets and trans. failures. Go to a Chrysler, Buick forum and they complain about some annoying rattles.

 

American cars are pretty good and long lasting, but there like the OZZFEST on wheels.

 

I like that big ol' Dodge Magnum for some reason a little more then it's 300C brother. I still have yet to see a 300 in black however and I'm sure that'll change my mind

 

Give ME a break. The combustion chambers are hemispherical, I'm looking at the teardown pics right now.

Oh by the way, 7000hp top fuel dragsters have hemi-heads.

 

Of course they are, I never said they were not. I said literbike and F1 cars use slightly domed chambers (with nearly flat piston crowns).

 

My apologies, Mike. After re-reading your post I realized my mistake. I thought you were implying that the new engine wasn't a true hemi. Sorry.

 

No problemo.

BTW, my 16yo daughter's BF's parents just bought a Durango with the Hemi. He just drove it over here (prom night), pretty impressive machine! They are going to sell a TON of those.

 

It's funny how everyone rants on average cars, but don't use their f-cars everyday ... damn ...do you all have rollerblades? LMAO

It's a Chrysler, and Hemi is just for the name, but I'd say you get your money's worth with this baby. I personally love the looks, and the V8 calls me. Since my chest isn't very hairy, I'd add a set of slightly more flowing exhausts and call it a nice everyday car.

If I was in the market for such car right now, I'd hit it! Just to encourage the big engines in average cars

 

What I don't understand is why the Hemi version has 340hp, and the other V8 version has 390hp... Why would Chrysler do this?

** Sorta resembles the Bently Arnage exterior doesn't it ? Buy the Chrysler and save enough to buy a house and have West Coast Choppers build you a custom bike.
