KLEEMANN C230 Coupe Pulley Dyno
Here is the long awaited KLEEMANN Kompressor Coupe pulley dyno. This is the STEEL pulley version- 8lbs heavier than the ALLOY version to be tested at the end of the week. Vehicle is my own 2002 C230 Coupe with 5K miles. Completely stock intake system and ex system. The Coupe has our 18" wheels installed with TOYO Proxes T1-S tires (rear 255 width).

That's impressive, correct me if I am wrong.
that's roughly translate back to:
223 hp compare to stock 192 hp
237 torque compare to stock 200 torque
I assume the lighter alloy pulley will produce even better boost.
How much is it installed again?

Calculations
Working the baseline run backwards to get the claimed 193hp I come up with an approximate 15% drive train loss. Using this 15% figure I arrive at 224hp and 252 lbs/ft torque.
Removing 8 lbs from the reciprocating mass of the crank could net as much as a 5% gain in peak power, or 11 hp and 12 lbs/ft. We will see shortly. The car is due back into the dyno by the end of the week if the schedule allows, if not first of next week with the ALLOY pulley. We are shooting for 200hp at the wheels.

if I install kleemann pulley, should I put the stock back on when I go in for the MB schedule maintenance?
I came up with 15% difference with the hp, and 10% difference with the torque.

Even better reason to tune it!
Our pulleys are black hard coated and very similar in appearance to the factory pulley. I would guess that most dealer techs wouldnt even notice the change. The pulley system is an easy enough thing to remove when its time to give it back too

KLEEMANN Pulley System price
The Alloy pulley system is $899 plus installation- usually about 2 hours. Available only at authorized KLEEMANN dealer/installers.

I wanted to install it right away but....
Conversion Techniques in Oakland, CA (Authorized Kleemann dealer) quoted me 5 hours labor just to install at about $90/hr. Is it something wrong there?

More-
John probably quoted you the time for the EARLY system which is more comprhensive and moves the mass air. I have talked with him recently so things should be worked out as to the labor.
No KLEEMANN dealer in FL as of the moment, maybe you could talk RennTech into doing the install?

KLEEMANN Dyno
Dyno is with KLEEMANN Pulley ONLY- everything else is stock: Airbox, airfilter, ex system etc. 6 spd gearbox with 9 x 18 wheels, dyno run done in 4th gear as it is closest to 1:1 ratio.

The graph is VERY impressive.
I remember looking for a pulley kit for a Mercedes SLK230 Kompressor, but found that the ones available required a chip to correct a dangerously lean Air/Fuel ratio in certain RPM ranges.
Why is a chip no longer neccesary after changing the pulley on the engine?
What is included with your kit?
Do you have any dealers in Toronto, Canada?

Wow, that's a great chart! I wasn't considering any performance mods to my car, but this has got me interested.
Is it required that the pulley be installed at an auth. Kleemann dealer or can we purchase it and install it ourselves if we're capable?
My next question is hard to put into words. I'd like to know if this pulley adds a significant amount of strain to the engine and related parts. In other words, does the amount of the increased boost max out the design limits of the engine or is there still some margin left. I realize there are no hard numbers or scientific evidence to answer this, I'm just looking for your opinion. I'm a commuter, not a racer and I don't want to be running the engine close to it's design limits just so I can claim XXX horsepower.
Lastly, have you noticed increased blower whine with the pulley? I actually wish there was MORE whine on the stock setup. I know it's wierd, but I've always had a "thing" for noisy gear drives and blowers.

Questions:
gab-
the steel version is, well, steel and therefore magnetic.
avlis-
the installation is simple enough but does require some tools the average person will not have. The peace of mind you have installing it at an authorized dealer is that you have somewhere to go if something isnt done right. Not to mention the fact that the dealer will have done MANY of these and there will be NO problems this way. There is more audible whine- no very loud but enough that you will notice it over stock. There is no free lunch, the faster you spin a bearing the faster it wears out. You are still well within the design limits of the C230.
KJ-Type R-
early version of the 2.3K engine had a problem with raising boost. The MAF signal would fluctuate at 3200-3500 rpm and cause a lean condition that was potentially dangerous but more annoying than anything else. The problem manifested its self as a serious hesitation. The new 2.3K engines (SIM4) moved the MAF to eliminate the problem. The ECM is always looking for a target lamda and will adapt new maps with the higher boost. We are not outside the range of adaption with the boost increase we use. The lambda is as is was stock at .85 under full boost.

KLEEMANN C230K
I know you guys hate when I butt in, but I have the kit on my early model c230k. I have put over 4500 miles on it (not those sissy miles either) it has not caused any "bumps or glitches" in acceleration.
It can be heard if you know what you're listening for.
To sum it up.....................EFFING AWESOME!!!!!!!
Brandon, I will be in LA on the 9th of Mar. (little GTG) hope to see you there.

Ok, here's a question for you... What if we live NOWHERE near Colorado or California? The Kleemann USA site only lists dealers on those two states? What does that mean to owners in the other 48 states as far as purchasing and installation?
