    • Another Supercharger system for the C63 AMG / M156 V8 motors? Xtra Power supercharger system claims 660+ horsepower

      Well, here is another M156 / 63 AMG supercharger setup. This one comes from Xtra Power (creative name, eh?) who we have never heard of. There are no boost numbers or pricing details given. The only details provided are that this puts out 660 horsepower with 595 pound-feet of torque and is available for all 63 AMG models. They also state that more horsepower is available with aftermarket cams and headers although no details on their cams or headers are provided. Is this legit? We do not know, but the forced induction scene for the M156 sure is heating up.

        These guys are located in Denmark. I was scratching my head about the grammar used on their news page but now I get it: http://www.xtra-power.com/index.php?...files/news.php

        Seems to be easier to mount on that motor. Plus, positive displacement with a 6.2 liter has to be a hell of a lot of fun. Better throttle response than a centrifugal.

        That is a major question mark.

        The dyno looks legit as far as the formula goes. Lacking many details though.

        The charger itself looks cool.

        Many of these new companies coming up with supercharger(s) for the 63 platform seem to be very tight-lipped about drive-train upgrade questions Click here to enlarge

        Wasn't the main issue about not being able to unlock torque parameters within the ECU? And is it more of a software issue rather than hardware limit issues(other than clutchpacks)?

        That is what MHP states.

        That is what we need answers to, I'm going to go visit the guys in OC who are doing the supercharger and ask them point blank.

        It isn't the hardware that is the problem.

        If it's making 660Hp then it's making enough torque to shred the trans in a week. Remember to use your AMEX card when ordering Click here to enlarge
