    Great stuff there Piko. What sort of power does that particular Evo make and I presume he giving it full throttle?

    Stock EVO 7 GT-A 272HP. We tried four times and the outcome was the same.

    You eather use a piggy back to alter the signal or just solder a 4.6V diode between signal and ground.

    This Frankenstein pipe mod gained almost 0.2bar by itself:






    Air box from a CLK430 and bypass valve venting out to prevent circulation of heated air through the charger.

    I hope you smoothed the bore on that bad mambagamba this is actually what I wanted to do as that baffle is pointless lol
    so this mod made boost and made the s.c louder I take it ?
    and where did you
    1 get the pipe
    2 the thickness of the pipe
    3 how hard was it to weld the pipe
    4 the corner section was that pushed inward?

    Love it! So, what power do you reckon the C200K is producing now. An honest 250/260 BHP?

    Yes it got a little louder. Mainly because of the open bypass.
    Got the pipe on ebay.co.uk, it's 2mm thick. A friend welded and beat it to proper shape. He's good with metal shaping. It's all smothed inside.

    I reckon it's at the 250HP mark. I'm making an even smaller charger pulley then it's on to th dyno.

    Beating a stock EVO put me speechless....
    That's beyond C36 realm I reckon.

    So by clamping the MAF you simply solder a 4.6v diode on the bridge of signal wire of the MAF and ground? I am not an electrician, not so clear on how to make out that part. Would be great if someone knows his stuff could be more specific? A picture or circuit diagram?

    I am going to put my header back soon since it's been repaired. Transmission is lagging sometimes, maybe I will check the fluid level and see if it's there.
    Right now fixing the car seems to be more important than making it go faster...
    Geesh... I hate hot Summer, here in Taiwan you get humid air 35' Celsius or higher at any time of the day during July and August.... Could definitely feel the car runs abit sluggish due to hot intake air
