    (Final Dyno) ACG Build: C63 Weistec Stage 2

    Here are the final results for ACG's Stage 2 build. The car had a few minor electrical issues that we sorted out over the past few days. What ended up being a faulty crank position sensor proved to be a real pain to diagnose. We made a few pulls yesterday in very hot weather and had to call it an early day. This morning we headed back to the dyno and below are the results…

    Thanks for the compliments guys. Boost is 13psi. We ran into an intermittent cam phasing issue which would throw a CEL randomly. Upon diagnosing the issue we found the crank position sensor to be causing this.

    At this point we have not hit a limitation in torque or any power reduction due to torque limitations.

    Are you hitting any torque limitations running higher boost, ie 15psi?

    Seems he's back to posting about it over on MBW. His initial driving impressions are that it is "undriveable" because the power is "instantaneous" and not as manageable as his AWD modded 996TT. This guy is a complete douche. 630whp on a heavy RWD 4 door - uhhhhh, DUH what did you think was gonna happen ??? It's already traction limited in stock form. Then he says quick lane changes in auto mode cause the car to kickdown a gear violently and essentially it's dangerous.
    Something tells me this idiot needs to spend some of his considerable wealth on a good driving school before one of his modded for tax purposes cars kills his dumb ass.

    My initial impression of him acting idiotically still stands. Does he understand the difference between a positive displacement blower and turbos? What about RWD vs. AWD? He has a problem with throttle response that is too good? When has this ever been a problem?

    This is one of those people that will never be happy and nitpick everything. The car is utterly ridiculous, I'll take the power delivery over a modded 996 TT (and M3) any day.

    100%. This guy is just one of those jerks that will ALWAYS find something to complain about. And he tries to pass it off under the guise of being "odd" or "weird". Funny too that he complained about the it having problems with the ESP on - another big f'ing DUUUHHHH - cause it's spinning the rears at 100+ mph and sending every sensor in the car nuts. Manual, ESP off every time you start the car. Lastly...wasn't he the one pissing and moaning that Stage II wasn't making enough power???? LOL, some people man...

    Not enough power? Now it's too much? Click here to enlarge

    I just want to commend ACG and Weistec for resolving this all professionally and for letting this guy essentially hang himself. They delivered as promised, now his problem is they gave him more than he can handle.

    Anyone who puts a supercharger on 63 and does not spend extramoney on new wheels particularly rears is wasting their time. From my oersknal experience with my supercharged black series 305s on rear are minimum requirement. The more I read the more this guy sounds like a petulant douchelord who will never be happy. Step 1 is get some bigger tyres mate

    He is doing a widebody conversion I believe and looking to put 315's out back...That should help with the traction but then all that load is going to put a strain in the driveline. I'd bet he'll be looking at new axles sooner or later. Or maybe not since it's pretty apparent he can't drive to save his life...and from what it sounds like, that 630whp is just begging to take the life of someone who doesn't knwo what they;re doing. But you hit the nail square with the "petulant" comment. Describes him to a T.
    Regarding drivelines between platforms...some good info in that MBW thread as far as part numbers for Black Series transmissions. It would seem that they are built stronger than the C63 722.9. Strange, but with such limited production I wouldn't doubt it and we've seen plenty of trans failures with the C63. Hey Propain, you go to your local MB parts dept yet to confirm that ? LOL.

    ...not to mention strain on susspension components and wheel bearings because I highly doubt he's doing a proper wide body conversion which would entale new control arms and wider axxles, I'm sure he's just throwing on wider wheels with a funky offset and backspacing. The car will handle worse than stock once the "widebody conversion" is completed. Wide wheels and backspacing does not a widebody make. I'm sure its gonna look cool but its gonna handle like my Ford Raptor.

    The 996tt is a huge value especially compared to newer AMG's so then why not due it?

    I'm not crazy at all though, turbo lag isn't my idea of fun.
