Supercharger Performance and Engine Performance Parts

Posts Tagged ‘Mercedes’

I’m going to talk about my own car for a bit here… I’ve been in the performance scene for a long time and have helped a lot of people fix, repair and build up their cars from being a stock neglected and abused second hand car into being a gem of a dual purpose daily driver and weekend racer.

One of the things that I’ve learned through experience, is that unless you have the ultimate in tenability on your car, with a control system that is able to compensate for barometric changes, varying load conditions, rapid temperature swings…etc then it is best to get a car that is very close in stock form to your desired power levels and use the minimal number of power modifications required to reach your ultimate power goals.

This path of 20/80 *using the 20% of the modifications that will give you 80% of the results* usually leaves you with a very reliable car, with proven power potential; a car that you don’t need to give your mother a pre-race briefing on how to drive it before she borrows it to go to the grocery store, and a car that you will never be reluctant to take on a long weekend road trip out of town. After all, the point of having an enjoyable car is being able to spend as much time enjoying it, rather than working on it and having it break down. This is especially true on a dual purpose car that spends a lot of time serving you in your battle against the daily grind of school, college or work.

So, in looking a car to buy as my daily driver after college back in 2005, I was looking for a car that was already supercharged (taking away the headache of finding a reliable supercharger kit and an intelligent engine management system that I could rely on). I also wanted a car that had potential to be slightly modified to make it more engaging and that had good handling from the get go.

In doing my research I landed on the 2005 Mercedes C200 Kompressor equipped with the M271 engine. The m271 engine is an impressive factory engine equipped with a lot of things that we usually upgrade on factory supercharged cars. The car utilizes a 4^th generation eaton MP45 supercharger utilizing Teflon coated rotors for higher thermal efficiency and an increased maximum rpm range of 16000 rpms and a peak power capability of 240hp or ~360cfm. Even in a low boost package of 4psi on the C180 and 6psi on the C200, the car is still factory equipped with a front mount air to air intercooler to cool the air charge down. On the intake side, the car is equipped with a generously sized air-box with a cold air duct to the front grill.

The engine itself is equipped with dual variable valve timing on the intake and exhaust cam for optimized power delivery, better emissions. The ignition system is factory fortified with a coil over plug setup but with generic Bosch platinum spark plugs.

As far as tuning goes, the car is equipped with an MAS air flow sensor and a MAP pressure sensor, as well as a transmission slip and wheel spin sensor. The combination of all these sensors is that the factory computer can very accurately distinguish between boost pressure and load by comparing actual acceleration with the acceleration demand. This load sensitive ECU also uses dual knock sensors equipped on the block to detect individual cylinder knock. The result of these factors is an ignition timing optimized for each cylinder based on boost / rpm / load and air flow with individual cylinder timing retard to keep as much timing in the engine as possible for peak power delivery, while retarding timing in the offending cylinder to prevent the engine from detonating itself to pieces in case of a bad fill of gas or a clogged injector..etc

Over all the car is an impressive factory package. However, a 1.8 liter engine in a heavy chassis with 10 factory air bags, fully adjustable front seats, xenon lighting, a sunroof, and other heavy Mercedes amenities leaves the car slightly underpowered and requiring modification.

Below is a list of minimal modifications that have proven power potential as follows:

1. Carlsson CK20 kit
2. Remus 60mm Catback exhaust system
3. ported factory throttle body

We are excited to release the second in our series of How-To videos on using the horsepower calculator.

In this edition:

Taking a 1.8 litre Mercedes C200 Kompressor engine to 320 horsepower.

First scenario: With camshafts for a power peak at 6200 rpms.

Second scneario: With stock camshafts, keeping peak power at 5500 rpms.

If you’re looking for supercharger tuning solutions for your E-Clas Benz, then you needent look any further…

Carlsson E-Klasse W212

Calrsson, the German tuner exclusive for Mercedes Benz high performance vehicles has announced it’s planned power packages for the 2010 W212 E class.

The new package includes a newly designed aerodynamics kit, the Carlsson C-Tuning suspension for computer controlled daming and a 43mm lower ride height.

Specifically for the E500, Carlsson is carrying over it’s CM50K supercharger kit (previously available for other 500 series such as the R500 and the CLK500).

According to Carlsson the CLK kit includes:

•     A clutched roots style compressor packaged with an air to water intercooler and integrated intake manifold.
•     Air is fed to the supercharger through redesigned Carlsson Air boxes fitted with Calrsson sport air filters.
•     The water side of cooling package includes a heat exchanger, external waterpump, and reservoir and expansion tank.
•     To support the added air flow more fuel supplied via upgraded injectors and a reprogrammed engine management system with removed top speed limiter.
•     Furthermore, the back pressure on the engine is reduced thorough the using of an entire exhaust system complete with tubular headers, hgih flow catalytic converters, and a stainless steel muffler.

The result is that “the Mercedes 5.0-liter V8 is fitted with a Carlsson supercharger, developed with Ogura Clutch and licensed from Wankel, which nudges output to 430 horsepower and torque to 480 pound-feet.”
