    Weistec 693 RWHP on ECM

    An article was featured on European Car Magazine regarding this beast.

    The objective was ambitious: to build the best of its kind. Or, in this case, to build something AMG might have done if it wasn’t constrained by budgets, lawyers and regulations.
    Starting with a 2009 M-B C63, San Diego-based Automotive Connoisseur Group (ACG) first addressed the power issue – as if this 6.2L V8 had ever been accused of lacking grunt!
    They bolted on a Stage 1 Weistec supercharger system that bumped power from the stock 350whp to a faintly terrifying 500whp. Along with the blower, it also included a new Euro-spec air box and mass air-flow sensor plus headers.
    Now we’ve covered Weistec-supercharged cars in the past year (EC 12/11 and 6/12), so they don’t need a long intro. But to recap, the system is based on a 2.3-liter twin-screw supercharger with an innovative Constant Mu, Delta Pressure cog-drive system that helps maintain constant friction and boost pressure.
    Unfortunately, 500whp wasn’t deemed sufficient to put it on a shortlist of the best C63s in the country, so Weistec’s Stage 2+ system was employed. In this iteration, the supercharger has a smaller cog, different headers as well as ported-n-polished heads with custom-ground 40mm intake valves and 33mm exhaust. You also get a bigger fuel pump, different spark plugs and re-mapped ECU.
    For this machine, ACG went a step further by swapping the stock rods and pistons for Weistec’s forged, ceramic-coated, Teflon-skirted pistons and billet steel rods – apparently these were previously used in engines built to come closer to the 1000hp mark. But in this Stage 2+ configuration, the engine cranked out 693whp and 583lb-ft of torque on a recent Dynojet run

    693whp is mighty impressive for the 2.3L. Shows its got quite a bit of meat in it.

    This is most likely a typo. It was 639HP but whose counting these days!

    Isn't this the car that was built for Sema last year to be ultimately stored in a barn somewhere in the US?

    I though I remember reading the motor blew up.

    For those with morbid curiosity, my C63 will not be heading off to its new home in a pole barn so fast after all.

    And I still haven't driven the car. I would be amazed if the car had more than a couple of hundred miles on it since I bought it a year ago but a couple of days ago it decided to grenade itself.

    Oops!

    The motor is getting torn apart but 1 piston grenaded itself (as in literally broke into pieces) and two more cylinders lost rings. Initial inspection shows no cylinder wall damage so it should be fairly quick to put it back together. Understanding why it happened might take longer.

    Anyway, I'm going to have ACG put the motor back together and dial the boost back, drive it myself for a few weeks to see how it holds together, then off it goes.

    I don't want to list all the mods. One, I couldn't keep count and besides the ones that might have an effect on this type of thing may not even be to blame. I haven't looked at the plugs. I have no idea what gas is in the car. I don't know if the oil squirters that should be under each piston were functioning. Etc, etc.

    Its too early to talk about why.

    I even have to go find the original purchase paperwork and see how many miles were on it and compare it to now.

    For all I know, someone had the car out doing redline doughnuts for an hour. I'm being facetious about that but really, I haven't even sat in the car in about a year.

    No, he was going to put it in a car crusher at one point as well.

    639 wheel horsepower Weistec supercharged widebody C63 AMG built my ACG (Automotive Connoisseur Group) featured in the November 2012 European Car Magazine

    Congratulations to Weistec Engineering on yet another magazine feature, this time regarding a supercharged C63 AMG in the November 2012 issue of European Car Magazine. This vehicle features a custom widebody and was built by ACG (Automotive Connoisseur Group) out of San Diego, California. The article states the vehicle has 693 wheel horsepower but apparently this is a typo as Wesitec stated the number is actually 639 wheel horsepower which makes much more sense considering the modifications.

    The article also states this is a Stage I supercharger system but for 639 wheel horsepower this is likely a Weistec Stage II+ M156 supercharger setup. This vehicle has a bit of history as the owner, well, seemed like he had a screw loose at one point threatening to crush the car saying he no longer cared about it on the forums. Simply odd behavior especially considering the end result is a spectacular looking vehicle with incredible performance. Simply great work by Weistec and ACG on the car and on appeasing an eccentric client.

    Full article is below, congratulations to Weistec and ACG once again.

    I wonder what happened to the owner? Wasn't he also near his deathbed or something like that?

    You sure he didn't crush his deathbed and get a new one because the previous one wasn't operating to his liking?
