Am new to this forum but just thought that I'd share my recent modding experience with you all. Just got the following installed onto my '04 C200K (M271), in various steps:

Step 1:
- MKB stage 1 ECU reprogramming.
- Claimed 28bhp increase. 20Nm torque increase. (resulting in 191bhp & 260Nm).

Step 2:
- AMG C32 front brake kit (calipers, discs, pads, sensor)

Step 3:
- Larger crank pulley
- Reduced water pump pulley (to clear larger crank pulley)
- New belt
- Fuel pressure regulator (up from stock 4bar to 5bar when manifold pressure drops).
- K&N replacement filter in stock housing.
- Claimed 25bhp increase, 40Nm increase (resulting in 216bhp & 300Nm).

Initial thoughts (based on my butt dyno, real dyno to be done in a couple weeks time when I get the time).

Step 1:
- Throttle response improved greatly at low RPM. Shows a lot less of the hesitancy for the engine to rev from idle to 2,000rpm. This was a big gripe I had with the car that was finally banished!
- Most of the additional power is developed between 3,000-5,500rpm... this spot feels a lot sweeter. And you can feel the car pulling noticeably harder than stock.

Step 2:
- Just decent stopping power. Installed with Step 3 in mind.

Step 3:
- What can I say? Major improvements throughout the rev range - just more power at every rev point. Power comes on much much earlier. Throttle response much livelier than before.
- I've never really been able to provoke the traction light to come on in bone dry roads, but after this mod, you can easily break traction when powering through corners.
- Fuel consumption has gone down the toilet though - but then, there's no such thing as free power.

I can't wait to get the car onto a dyno to see exactly what power I've got now. Overall, I am happy with the power gains. However, I did see a particularly tasty high-flow intercooler at the workshop just before I left.

Interesting! Post that dyno!

Woow, Please post your dyno result.
Am also thinking of these Mod.....Klemann, but am waiting for the warranty period to wear off before I start meddling with it. Mine is a standard C200K Sports edition

Any reliability problem with day to day driving ( hate to send car in for repairs). Maybe u want to take a look at the Klemann header.....

Happy Chinese New Year

I've just had it for 3 days now. Took a long drive on open roads. After 350km of highway drive, the following are what I observed:
- 2nd and 3rd gear acceleration has significantly improved.
- engine note harder edged. Not as quiet and refined as a merc should be.
- acceleration from 100-200km/h significantly improved.
- pulls to an indicated 240km/h and still feels like there's urge but sadly there wasn't enough road.

Fuel consumption took a big hit. At least 2L/100km more on average, and worse if you're driving WOT all the time. But I guess this is the price for performance.

Gong Xi Fa Chai to you also.

Thanks for the awesome post! Can you show some pics?

where did u hit 240kmh? malaysia i hope

*wink wink* let's just say that it was an open road with no other cars in sight...

On a separate note, does anyone know what the variance between speedo and actual speed is? From experience with past cars, I tend to find that speedo's over-read quite a fair bit at the more extreme end of performance. Will need to dig up that handheld GPS to really get a good guage of how quickly I am travelling...

:v :v

if you don't mind, could you pm me the location and time you did this? i wouldnt mind trying out my max speed as well.

dgwee

Me too...please pm me... Need a place to "exercise" my wheels... Have never gone beyond 100km/h since I got my ticket a few months back :p
