    hallo to everyone my car is slk 200k with 163hp.....

    after many modifications such as
    remapping of the ecu
    bigger and more efficient intercooler
    62mm pulley for the compressor
    parallel ecu in the map sensor reaching the point of 1.1 bar overboost
    k&n air filter
    hand made manifold,hjs sport cut
    195mm crank pulley and 120mmpulley of water

    with the above i have reached the point of 230+hp

    now my new project is to find information for new aftermarket even handmade camshafts in order to use more effectively all the above!!!

    do you have any idea for camshafts for my car????

    My mother had the SLK 230 Kompressor. Got rid cuz it was too slow. I mean, a 2.3 with a supercharger only making just shy of 200bhp is a bit perthetic.

    But why not do an engine conversion to the 3.2 Kompressor engine and you'll have a much better starting base and should see it up to 300bhp area.

    Is your engine model M111 or M271? Dr. Schrick http://www.avl-schrick.com/ had earlier cams for the M111, but now they have only cams for newer 6 and 8 cylinder Mercedes engines. With luck you could find Dr. Schrick cams on ebay.de.

    Easier way is to just re-profile and fit top hat shims to counteract clearance to be back in hydraulic lifter range.

    Maybe so if you know what kind of profile works well with the variable cam timing.

    Most important is that the lobe separation is not getting too much. 10 degrees of increased duration is quite a bit in terms of power.

    The Mercedes M111 variable cam timing keeps the duration constant and advances the intake timing (and valve overlap) with 20 crank degrees from approx. 1200 to 4300 RPM.

    The duration is always constant on rigid cams. Variable cam timing wouldn't affect it.

    You need systems like the three variants of FEV or Scheffler's Uni air system, which is currently being used by the Fiat group (called Multi air).
