So I'm asking this question for one of my friends who doesn't use MBWorld.
The question is, why is there supercharger kits for the W204 C63 but not turbocharger kits?
I know the engine is high compression and isn't meant for forced induction... But supercharger kits are still available

 

Because the m156 is naturally aspirated and that's what makes the w204 a w204.

 

That doesn't answer my question, I'm talking about aftermarket

 

Turbo requires more parts, runs hotter, requires more room, and is is typically less reliable then a supercharger. With the torque this car already produces you def don't want an abrupt torque curve of a turbo to help break the tires loose that are already crying for traction. A super chargers curve is much more linear in power delivery it's still going to shread tires for sure but more controllable.

 

I always thought turbo's are more reliable since most every car brand uses them in stock engines other than superchargers

 

First a motor that is designed around a turbo completely different then what your talking about. Your talking about adding a turbo kit to a car that's not designed for one. Different animal. More issues then a supercharger. Most importantly more expensive to the consumer because of more parts required. People like the sensation of the turbo torque curve that's why your seeing it in new cars today.

 

With a 6.2L Engine, you'd need a very large turbo from factory, otherwise the turbo won't be in it's efficiency range.

Larger engines, it's easier to Supercharge than it is to Turbo. That's why the the 55AMG were Supercharged. If you look at all the new Turbo Motors, they're all typically 4L or less.

And no, a Turbo is not more reliable than a Supercharger. In fact, Superchargers are likely more reliable, depending on the type of it.

 

Did I not ****ing call this? From the "flat crank" thread on 11/11... :cheer s:

Your answer: No room, or, too expensive. Not to mention someone stuck a 5.5TT into a BS and it turned out to be slower than a weistec s/c application and cost way, way, way more money to pull off. Other TT applications you'll find are off e55/cls55's that come s/c'd from factory. Some crazy **** is running around with a TT setup but those turbos are practically under the car if my memory serves me correctly.

God damnit though, I am almost happy this thread came up. Now I can convince myself to buy a lotto ticket or something

 

They make Twin turbo kits for Gallardos/Vipers/ Ford GT's with massive power and all the engines are bigger than 5L.

I thought the problem with the C63 not being able to be turbo'd was because there isn't enough space in the engine bay?

Gallardo is a 5.0 or a 5.2, close, but not quite.

Ford GT is a 5.4L Supercharged Motor from factory.

Vipers are a different story.

However, these cars do not run a conventional turbo setup, like a factory turbo car does. If I recall correctly, they run theirs way down the exhaust. It's essentially a "rear mounted" turbo setup, but it works because they are mid or rear engined. Most factory cars have it coming off the block. Or, smaller motor cars also do that, like an FRS or a Honda.

BMW I6 Turbos also have theirs coming off the block, where their Exhaust Housing (Header) and turbo are one piece, whereas the UGR Kits, for those bigger motors have them coming shortly before the exhaust exits. Different designs for different spaces and vehicles.

Similarly to how a Porsche Cayman 987.1/2 is Boosted.

Simple fact is there isn't enough room, and it would be a lot more headache to get it to work.

 

You sure did! When I saw this I assumed it was someone trying to wind you up...


The ONLY reason people aren't trying to turbocharge these things is because there is no room. It's hard enough to fit some decent headers, let alone a pair of turbos. A properly turbocharged M156 would be INSANE!!!! (in a good way)

 

The problem is definitely room. SC is more reliable but turbo is more efficient. Also with the proper tune with say a 76mm turbo would destroy a stage 3 Weistec. All you have to do is turn up the boost.

 

You could remote mount the turbos, and then find enough room. I prefer turbos where it's hot and the exhaust gasses are fastest right off the block though, and there is simply no room with our cars. Although you could put a couple small ones where the primary cats sit, they wouldn't be big enough to make a difference. And turbos are WAY more efficient than superchargers, free energy (ie don't siphon power off the pulleys), and you can turn the power up higher too.

 

Turbos are in fact more efficient. You would have to do a turbo muffler for this car. Turbo are not instant torque like the roots style super chargers.

 

Superchargers suck. I want turbos.

 

Well I mean look at the E63 AMG Biturbo which is 5.5L or the S/SL65 AMG, 6.0L Biturbo

 

And the turbo question is a valid one in my opinion, because many people simply just don't like superchargers (including myself)

 

^ There is no reason to not like a s/c application.

Again, yeah the e63 and s class have turbos and someone just posted a thread with like a gl63 that is turbo'd... The difference is those cars are much bigger (so have more room) and also still have smaller engines taking up less space.

Bottom line is it isn't happening in a c-class for a reasonable cost. You could put in little snails as someone mentioned could be possible but again, insane costs on minimal gains on baby snails.

If only mercedes made a twin turbo c63 from the factory that had the ability to be tuned so the giggle meter exploded... If only...

 

Nothing happens on a Mercedes for a reasonable cost....

 

not liking superchargers is just a plain ignorant opinion. So do you not like top fuel dragsters? massive power? do you hate alcohol, race gas and nitrous too? dislike rotary engines or electric cars? lol.

no turbos - because no room, cost and complexity. Have ya'll ever worked on your own cars? It's all about packaging. screw type superchargers have instant response and full boost at any rpm. most c63's are daily driven and thats where you drive the most idle -3krpm.

The reliability thing that keeps being mentioned i have no clue about. Both turbos and superchargers are reliable. I have no idea where that argument stemmed from. Efficiency sure, turbo's dont take power to make power. They are utilizing unused heat energy. Engine size doesnt have anything to do with it.

Have you ever priced out a tt gallardo/ford gt/viper build lol? 100k$+? Im sure for 100k weistec or any other tuner could put something together for you.

76mm crush a 3.0L blower car, possibly... If you could put the power down, use a standalone to setup antilag, and build a transmission to hold it. Ofocurse whipple does make a 5.0L blower lol, may need a promod 94mm to compete with that

 

A 76mm setup not including driveline upgrades should run about 10-12k. Anyone paying 100k for a turbo kit on a c63 is a complete idiot.

 

Ok, I'll bite. Where are you going to put it? The turbo(s).

And please tell me who's going to do that for me with tuning for $10k so I can call them tomorrow. Thanks.

 

Like I said in my first post, room is the problem.

Stage6 Motorsports has been doing setups for SRT vehicles for years. They also work on many exotic.

 

While we daydream why not just put the 4.0TT in the new c63s into our car. There ya go. I think it is even the same tranny so there is one less headache!
