facelift w204 c350; 300+hp, 7200rpm redline, anyone know the changes made?
So if I understand correctly, the new c350 is getting somewhere around 305hp and like a 7200rpm redline?
So, I hear direct injection has been added.
What has been done to accompany the increase in redline? Valvetrain? Rods? Bearings? Approx 1000rpm increase, unless MB prepared the c350 for this abuse beforehand, something certainly has been strengthened?
Pardon my ignorance of OHC motors, but are there valve springs? Id think these would otherwise be the first thing to need beefed up.
Any ideas?
Whatever the case, my 3.5L that could is getting whatever spa treatment the new c350 is blessed with come hell or high water

I think that the mentioned 3.5 putting out 305hp is from a new family of engines with direct injection from the M276 rather than a reworked M272.
http://en.wikipedia.org/wiki/Mercedes-Benz_M276_engine
The first line of the second paragraph really scares me.
Also the M271 lives on as that has been re-worked with Turbo power with more hp and lots more torque (201/229). It will be replacing the existing 2.5L and 3.0 M272 as the upcoming base engine for the facelifted 2012 C class. It offers the same acceleration 7.1 sec but giving an extra 4mpg. Lets hope they get the cam sensor problem solved for this engine.
4 bangers are the engine of the future as they need to extract as much power from the smallest plant while saving on weight and fuel consumption. (even F1 is going to 4 cyl engines) The next gen 1 and 3 series will have 3 and 4cyl engines!

Hopefully the turbo will "refine" it a little more so it's not quite as harsh as the current s/c version.
Where's OneofakindTrini at for this talk of turbos? A turbo thread isn't the same without his presence, as well as an Evo reference! lol

Forgive me for my ignorance but what does a S/C have to do with refinement of an engine? It isn't a technical thing by a long shot but I prefer superchargers over turbochargers because of sound. Man I love the whine. Cale, you have been in the C230K cars, right? Not just parroting Glyn on this?

Per my quotations around the word refine, I was simply referencing, taking it as Gospel anytime you, or the omniscent Glyn... mentioned this trait of the m271; I have never ridden in a m271!
Being that inline engines are supposed to be quite smooth, I chalked it up to the belt driven supercharger and their slight lack of efficiency compared to a turbo.
So, I said "hopefully" the new turbo setup will improve it.

I'm hoping that down the line when I replace the mounts it will restore the smoothness overall. It has lost some of it with age, no doubt.

the M272 version would be the E35 from the SL350. 302hp and 7200rpm redline. you would think the M272 would last a while, but MB likes to change the engine every 6-7 years and the M272 is going to be 6 yrs old.

IMO Turbo spool sounds much better than a supercharger whine. Turbos are much more efficient as well. With the advancements with bearings the once hated "lag" is slowly starting to fade.
For the M271 I think the turbo move from benz is to make the vehicle more efficient with more power.

New technogolies in bearings and oiling systems have made turbochargers even better and more economical.

The N54 twin turbo has no turbo sounds that I have ever heard under any circumstances. But the M271 has an audible whine.
I applaud Benz for making the W204 class competitive with 300hp. Still, I'm willing to bet it will be no match still for a 335i in performance. Lack of a proper manual is an epic fail, too.

And yeah I'm with you on the manual issue. They won't beat the Bavarians unless they can develop a quick shifting auto that sees its way into more than just AMG's or simply add the 3rd pedal and have getrag design a 6spd

Turbo sounds or not it hauls *** in the right gear. There are many DIY's to open up diverter valves on the i/m on e90post that I've seen..

Nah bro someone working in the yard bought the red one and there was a white MR selling but it sold for 11,500.. way too much for a evo with both airbags deployed. And just my luck that while my car was parked there someone gave me a nice scuff on the side of my right rear 1/4 panel.

Uh yeah give MBUSA's "pimp my engine" hotline a call. I'm sure a qualified engine builder will get right on that parts list to update your engine.

Different compression ratio, different cams, different head, completely revised intake manifold, different tune. This is not an educated guess.

Yeap, the 3rd pedal is really needed to maximize the expierience.
