    GAD C63 BS BiTurbo vs. Porsche 991 Turbo S (stock)

    Hi Folks,

    nice video which shows the GAD-tuned C63 BS BiTurbo in Action.

    Maybe not really fair to compare the stock Porsche to a 850HP (crank) Benz, but nevertheless quite impressive and very interesting...Click here to enlarge The C63BS has M157 Engine-Swap and 4-wheel drive.

    Enjoy:

    GAD M157 swapped W204 C63 Black Series 4Matic details plus race versus a stock Porsche 991 Turbo S from a roll

    The W204 C63 AMG comes stock with the now officially gone M156 6.2 liter naturally aspirated V8. In the new 63 AMG models Mercedes introduced the 5.5 liter twin turbo and direct injected M157 motor. Well, German tuner GAD-Motors had the brilliant idea of swapping the new M157 V8 into the W204 C63 AMG chassis which unlike its 63 AMG siblings never was updated to the newer twin turbocharged powerplant. As the race against the 911 Turbo shows, the result is a car with devastating performance.

    GAD-Motors pulled off the swap and the icing on the cake is the addition of the 4MAtic AMG powertrain. They also gave it upgraded turbochargers. Yes, this is a twin turbo V8 all wheel drive C-Class. Essentially it mimics the E63 AMG S although with less weight due to being based on the C63 AMG Black Series. The result is a car that moves very well as is shown in the video below against a stock 991 Turbo S which itself is no slouch. The 10 second 911 Turbo just gets demolished.

    All this does though is make BenzBoost yearn for an M157 V8 paired to a lighter chassis. This does highlight the problem for Mercedes-AMG though as a C-Class with the M157 is just going to annihilate everything else in the lineup at least in a straightline. Apparently Mercedes had enough of C63 AMG owners tuning their cars making them much faster than the other 63 AMG's in the lineup with software alone.

    Enjoy the race video although like most race videos from the Middle East the video quality is incredibly poor for whatever reason. Expensive top notch cars yet cheap low end video equipment, you make sense of it.

    If this was a sedan, it would be my favorite car.

    There is no reason they could not do the same with the sedan.

    Their wheel choice is interesting. 11 fin with slightly larger exhaust wheel to match.
    the gap at the top on the exhaust wheel seems abnormal. @VargasTurboTech any comments?

    Care to expound on what you find interesting about the wheel? How many fins is the stock wheel?

    Tht's very interesting... all the M157 turbo upgrade available from Renntech , Weistec and AMS consist of a modified Cold side...(Upgrading the compressor wheel)

    But here the Hot side is also modified... Did they cast their own turbine wheel housing ?

    I think the race just happened without it being planned and using a phone camera,thus the poor outcome.

    Go-Pro's on board never hurt anybody.

    The compressor wheel is relatively old school. I am more interested in the gap at the exhaust wheel.
    Did you not right the article on the wheel comparisons of Weistec and AMS etc?

    I wrote it but that was a comparison of journal versus ball bearing more than an analysis of wheels, fins, etc. I'm interested in learning as well and don't know every automotive topic inside and out.

    Wow 4matic too. This thing is a weapon straight up. I have to say though I still love the M156...that sound will never get old. Agreed that this would be even more badass in the sedan....for some reason the W204 coupe is ugly as balls to me.

    Interesting point about the turbo...would love to see some dyno graphs here.
