There IS a pulley kit for the 1.8 L M271 engine
I found this at Autowerks:
Carlsson Performance Kit CK20 (emssion standard D4) Consists of a special belt pulley, vibration damper, deflection pulley,
special airfilter and Carlsson chrome insigna.
Only for cars with engine type M271
Fuel: Only 98 Octane! Part #11 33 0203 D
Performance details on request
Only $1900.00

They don't show it on Carlsson's website but $1,900 sounds about right for their pulley kits. Performance detail on request, that sounds like it's free. I think they say 98 RON just like Vaeth says the same thing on their site for pulley kits for the M111 that's the same size as the other tuners like Kleemann & ASP that run fine on 91 octane.
Why don't you chip in and buy it as a group, test it and then if all works out have ASP make the same pulleys for the group for a fraction of the cost (without directly copying it of course, just send them your factory pulleys you removed and tell them what diameter to make them). When Timmy and I put the group deal with ASP they sold like 40 of them in a year not counting the SLK sales. For example if 19 people bought it, the additional costs on the ASP would be $100 each. Figure that now there are 1.8L sedans in the mix that should be an easy target.

Buell,
I found it at Autowerks, I couldn't find it on the Carlsson's website either. Part of the $1900 was Vat tax which we don't have to pay. Also that was installed price and with a "improved" air cleaner and Carlsson chrome insignia. We could perhaps deduct $250 for installation and $100 for the air cleaner and insignia. Still expensive.
I would not mind a quality dealer such as Evosport doing what you sugest. My feeling is we all should support dealers who support us.
A win win situation. Ben and Evosport have helped us with group buys before. This latest C32 brake upgrade was fantastic. Any usually we end up spending what ever we saved on the group buy by getting something else form the dealer.
Heck, perhaps Autowerks could get this ball rolling. MB owners certainly spend enough with them. Only problem is the dollar vs. Euro is not good right now. European prices will be going up for all items.

Evosport should contact ASP for pulleys. I did not mean to imply installing the overpriced Carlsson parts. Even Autowerks won't sell very many at $1900, and they are the Carlsson dealer. But maybe 40 per year installed by Evosport at under $1000 installed would be a good start for Evosport.

Whoa, guys slow down, I don't think this pulley will work on the C230
In Europe the same 1.8L engine comes in 3 flavors. The C180, C200K and C230K and I think the latter 2 have the same SC but at different boost levels. I think this Carlsson pulley just brings the C200 up to C230 boost level. May be I am wrong but that's just my guess. The other issue is that the M45 has a max rotational speed of 14000 rpm. We need to know what its max rotational speed is currently with the MBZ pulley at 6000 rpm before we try to find something to make it spin faster.
What do you think?

The new M271 engine is widely published as using 11 psi. Working the math backwards knowing that is a .75 liter SC and a 1.8L engine a drive ratio of approximatelt 2.35 to 1 is the result (using 30% as a pumping/plumbing loss through the entire SC system). End result is a SC speed of 14,100 RPMS at redline. The 14,000 figure is the maximum permissible CONTINUOUS speed. In theory there is room for a higher drive ratio- the problem being the SC is already outside its efficiency. You will soon be at the point of diminishing returns (where the SC speed goes up, boost goes up but at the price of heat and additional drive HP that CANCELS the potential power increase from the boost increase).

All the info at Autopwerks said was for the M271 engine. It did not say which one. But the clues are:Consists of a special belt pulley, vibration damper, deflection pulley"
So they have a crank pulley and a deflection pulley. I agree we need to find the relationship between the stock M271 engine and the supercharger pulley. My asumption is 2 to 1 stock. So at redline of 6000 the supercharger is doing 12,000 RPM. Even 5% more rotational speed would help the Eaton supercharger give us more HP at RPMs where we need it. I want HP at 3,000 engine speed to 5,500 speed.
Anyone with a 2003 6 speed. Put a mark on the supercharger and one on the crank. Leave in gear and push the car forward. This will require two people. Just count the rpm of the supercharger when the crank mark has gone one rotation.

I really think underdrive pulleys for the alternator and water pump are just as important as overdrive for the supercharger. HP is HP it don't matter where you get it. I am assuming all the MB alternators are nearly the same, so a underdrive pulley should work on all. Freeing up 7 to 13 HP is sweet.
That is the reasoning for the turbocharger group here, if there is 30 HP parasitic drag on the supercharger, a turbo at the exact same boost would have 30 more HP at the rear wheels, perhaps more because there is less need for mufflers with a turbo.
I would bet the M271 can handle one bar (14.7 psi) very easily using a turbo. That would probably give 260-300 HP at the flywheel.
Still I have had turbo cars before and much prefer the MB supercharged coupe. I prefer to work on getting more HP out of the M271, we will have underdrive pulleys, air cleaner mods, IC improvenents, ECU mods, and perhaps a modified Eaton supercharger. Just takes time.

Nevide, tirbos require much more complicated plumbing
And don't forget they are prone to premature failure due to oil starvation if the user does not follow proper shutdown procedures.

breastroker, you may know what you are talking about, but you've made lots of assumptions about the M271 engine and I think you should get better information before you start tuning it on your own.

If we can get 25-30 people to CONFIRM they want a kit, we can make one, no problem. However, if what Branodn says is accurate, there will be no reason to do one.
Thanks
