    • First Supercharged M156 63 AMG Motor by Weistec Engineering

      Here we have a teaser video of a supercharged M156 V8 on he C63 AMG. There has been a lot of discussion of this not being possible and extremely difficult to excute. So far, it seems Weistec has been able to get the hardware down using a 2.3 liter twin screw supercharger. We do not know what boost they are running (likely somewhere in the 6-7 psi range if on pump) and we do not know the cost or even who is doing the tuning. More on this as it develops but we are glad to see this is being attempted and development is moving along.

        Nice find, now we have numbers. The SC is running good. Lets see how things develop.

        I found more info about price and what the kit includes on their site. A stage 2 seems to be in the works.

        The above mentioned $27,999 is the price of the SC package for the SLS

        "Pricing for our Stage 2 system is not on the website as of this time, but we don't expect a huge jump in cost. More information will be available shortly. "

        I wonder what they are using to tune that.

        Sounds tits though!!

        Cost: If you think this blower is coming in under the $15K mark lol, well, I don't know what to tell you. That nixes 99% of the potential market, as customers already complain about the cost of significantly less expensive yet highly effective parts. We'll see how many "I'm in"s we'll get once the price is announced.

        Overall Output: This will be capped by the trans and fuel management, even if they are using a piggyback unless they replaced the entire fuel system ($$$) the max you're going to see this combo put out is ~500rwhp. Which is what we get from headers, mids, tuning, and airboxes N/A. If you spent the $ to replace the fuel system you still have cast pistons and 11.3:1 static CR with PFI to deal with. Meaning you are not only electronically and driveline limited (trans) you are also mechanically limited by the shortblock.

        Blower Size: I can see that they were targeting stock or near stock cars with this kit as the inlet issue and wrong size supercharger were used for this application. If they had higher outputs in mind (aka going in and rebuilding the shortblock) they would've used a 2.8L or larger blower.

        Trans: Unless they cracked the Holy Grail and I don't see that being the case, this car will $#@! a trans in the first week. It should be making an easy 525-550rwtq with that 500rwhp, BTDT with that kind of torque and the results weren't pretty. Now add to the load that PD blowers make peak boost just off idle (especially in a low boost app like this) and you have a serious recipie for disaster.

        Converter: LOL, just LOL for now.

        Inlets: The blower in question uses the stock inlet tubes which are restrictive on a N/A M156, PD blowers are especially effected

        I know there are quite a few M156 owners that want to believe this is a cost effective forced induction solution, however if you know the facts now you can already tell how limited (power production wise) and expensive this kit will be. Aside from that you can make the same power N/A with much greater reliability, no heatsoak, etc.

        In summation I feel this will be the most overanticipated and underdelivering mod yet for the M156, cost per $, and that is if they can not only get it to run, but to do so without grenading the driveline first. Like it or not nothing about the M156 (save cylinder count) is on par with the S65 in terms of being ready for forced induction.
        You bring up a lot of good points Andy....NOT!!!! LMAO when I read this post, he hit the nail on the head exactly ZERO times.

        On paper this project is still a disaster because zero driveline solutions have been presented. They figured out the easy part (getting it to run/idle) as others have in the past (Brabus), now getting it to work along with the rest of the driveline (shorterm or longterm) is a different story altogether.

        Fact is we can offer upgraded engine internals now. We can also offer upgraded trans internals now however they are useless unless the software can be changed to accomodate them and the application at hand. Aside from that how many people will spend $40K upgrading the engine/trans internals/fuel system only to find out they have a tiny 2.3L blower sitting on top of the engine that then becomes the limiting factor.

        Until I see hard data telling me otherwise (and that would be a first in this instance) there are just too many problems and stipulations on the table for this to make any sense. Best case scenario this is a quiet 480-500rw solution.
        Another bullseye by Andy ROFLMAO!!!

        Weistec is currently making 660 whp on at least two cars (mine and Earls), we are both running stock trans, converters and TCU's

        ...I personally like the following Andy quotes "even if they are using a piggyback unless they replaced the entire fuel system ($$$) the max you're going to see this combo put out is ~500rwhp"...Andy's posts in this thread alone are enough to completely discredit his knowledge of these motors and drivetrains.

        Clearly they exceeded the supposed 500 whp limit by quite a bit. Those posts look very odd now.

        There will always be doubters. Without doubters we wouldn't have pioneers.

        Off topic but I think it applies.

        A buddy of mine just shoehorned a Cummings diesel(straight six) in his 1980 Camaro after everyone told him it can't be done. Turbo is not on yet.

        He is sick but extremely smart and handy.

        This was his car before he took on the new project. He ran a best of 9.70 @ 150
        after the article was written.

        Never need to apologize for that on this site especially with car related content.

        I just wanted to update this post. Sorry, I know it's off topic but I thought it was pretty cool.

        Car is almost done and is running strong, needs to be tuned a little more.

        Makes 60 psi of boost.Click here to enlarge

        That's a great project! Would love to see updates whenever they dyno or video some runs!
        What sort of gearing and tranny does it have?
      1. PetroC63's Avatar

        3.08 gearing in the rear. Trans is a Turbo 400 with a 13" bus converter that were both rebuilt to handle the massive amount of torque(1500 ft/lbs).

        I'll keep updating as he progresses. It's been a long process, he shattered the last torque converter to pieces.
