I dunno what to say to that. Honestly I wanted only lighter pulleys and not bigger ones...
And you dont think if all mercedes share certain parts it would not save them money when they build it?

Not only does MB share parts across platforms but soon they will be sharing parts with it's Chrysler division just like Ford/Jaguar or VW/Audi share parts.

Hmm, a bit OT - but the development costs for the new C was not in the million dollar range, but the billion. Around 1.3 billion dollars were spent developing the W203. In my belief, you don't spend this amount of money if platform/part sharing is a primary goal. I bet MB did a huge amount of research on wich pulleys to use. Not said that they (the stock pulleys) contribute to maximum performance, but I'm sure some engineers did some serious "trade-off" thinking. 
Glad you're happy with your new mod BrabusCClass! A pulley upgrade will be my next upgrade too (even though I plan just to stick to a larger crank pulley 
)

Like I said, its not cost that limits the pulley choice, its designing a car thats reliable in ALL situations. The underdrive pulleys would not provide a safe margin in all cases so they don't use it. They know all about the benifits but are taking the minuses into consideration.

Class C can tell you how well my car performed on our long caravan up north. 100F degree weather with A/C on my car was still pulling strong. After seeing my car in action he wanted the pulley kit. I think he is going to get it very soon.

You are right! BrabusCClass's car preformed very well and was able to pull on me in several occassions, damn him
we have the identical car with the exception of mine being auto.
The kit is definitely worth it especially on 240's, any HP gains is a plus for our sluggish 1st gear.

Mercedes, and all other manufacturer's design all parts of the car to be suited to the largest available market. If it wasn't for this, aftermarket companies would have little business. Take your suspension for instance, it was designed to be comfortable and provide a quality ride for the majority of C class owners out there. Still, many people feel the need to upgrade their suspension to one that provides a better driveability suited to their needs.
The pulleys on the C class are the same as the pulleys on almost every other '98 and on Mercedes V6 and V8 (except for a limited few 98 models). Mercedes did not spend billions or even millions over and over with the production of each new engine. Instead, they chose to take parts (water pump, power steering pump, and alternator) that were already in production, and use them on their future models. This is the case for many Mercedes parts. Take the CLK for instance, the CLK has 2 Left-rear rotors. You can verify this by looking at the veins on it. Why is this? Because they found it not necessary to change the rotor, and it saved millions due to already being in production. The same is the case with the pulleys.
With that being said, Mercedes designed their accessories and pulleys to produce a certain amount of output that they deemed safe (exceeding required amounts) in order to please all of their customers. Our UD pulleys are designed to take some of that power back to the engine, while still keeping the car reliable for most people's needs.
Thanks

ud pully on c240
I see you installed the evosport ud pulley kit a while ago. Have you noticed any problems? Also do you know of anyone that has done a ud crank pulley? I have seen some say its not safe to do the crank. Any insight would be great. I am plaing on a ECU upgrade and the ud pulleys and a full exhaust in the future. I would like to get as much as possible from my c240. I also dont use the AC much is there a pulley for that aswell?
Well I just came back from Evosport and I had their underdrive pulley kit installed. It was a short install, about an hour. The funny thing is I just serviced my car yesterday so I feel a big difference but I cant tell if this added power is from the pulley kit or from my service B.
After the pulley kit install I realized that with the A/C on I can feel much more power. It feels normal as opposed to before when I could feel the drain in power as soon as the A/C was turned on. Im sure people with the 6speed C240 knows what I am talking about. I had a auto C240 as a rental and I didnt notice that much lag with the A/C on like my car.
Anyways, I drove in traffic on the way back, 90F weather, and with the A/C on my car ran as good as it would have with no A/C on. Im happy with this investment I did.
If anyone is looking for these pulleys contact www.evosport.com
