    • Weistec Engeering Stage 1 63 AMG M156 V8 supercharger is now 50 state legal - CARB certification approved

      A major congratulations is in order for Weistec who managed to pull off what many said would be impossible. CARB certification (California Air Resource Board) is extremely difficult due to the strict emission controls employed in the state. It is usually only large manufacturers making parts for domestics that have any luck with CARB certification using aftermarket superchargers (Magnusson, NOVI, Stillen) and we searched but could not find another modern example of a CARB certified aftermarket supercharger system for a Mercedes, BMW, or Audi. Not Dinan, not Renntech, not Active Autowerke, not VF-Engineering, not APR, not ESS, not Gintani, nobody producing superchargers for the aforementioned makes has achieved this on a platform produced in the last decade. That should put things in perspective.

        But the warranty will be gone though, right ? Not sure why anyone would ever have an MB dealer do the install with their jacked up labor rates. Plus, they don't really have much experience modifying cars. I realize the Weistec kit comes with detailed instructions, but it's not your "average" mod...

        Well a dealer could install it now legally after the warranty is up for example.

        This could lead to dealer agreements that would not void the warranty though.

        I believe @Exeenom was referring to MB dealers as Weistec dealers were already doing installs.

        Yes I was referring to Mercedes dealerships. Regarding supercharger/turbocharger installs, the most common answer I got after asking dealerships if they would do an install (in the past) was that they couldn't simply because it was NOT legal. So now after Weistec has been approved, assuming the customer doesn't care about warranty, would this facilitate such a process?

        I think that alone was worth the trouble.... Many people tend to deal with local dealerships instead of going through all the trouble of using a longer-distance shop and so this option will provide a great solution for them.

        Obtaining CARB approval for any aftermarket hot rod hardware is neither easy nor inexpensive.

        Congratulations are indeed in order to Weistec Engineering for having jumped through those substantial bureaucratic hoops.

        Not really. LZH is right.

        The vehicle warranty comes from MBUSA, not the dealership. MB dealerships' independent agreements with third-parties don't "trump" whether or not MBUSA honors or denies a warranty claim.

        Say hypothetically an MB dealership installs a Weistec S/C on someone's C63. Then the car starts running rough and they diagnose that a con-rod has weakened/bent and needs to be replaced. That dealership might go to bat for the customer with MBUSA to try and get an exception... but that's about as far as they'll go, and if MBUSA still says "no" - do you think the dealership is going to warranty it themselves and eat the expense? Not likely.

        This noteworthy achievement is simply about meeting Federal and State emissions legality in the United States... it'll have no bearing whatsoever on affecting MBUSA's new-vehicle warranty coverage.

        Just like with Dinan the dealer would put in place their own warranty in lieu of the manufacturer warranty. That is why I specifically said dealer agreements and not MBUSA as a whole.

        Again, I think you're mistaken. The Dinan warranty comes from Dinan, to make their customers whole in the event BMW denies a claim. So, the analogy would be for Weistec to give AMG owners a warranty replacing any lost coverage from MBUSA. Not the MB dealerships.

        You misunderstood me again. Dinan supplies their own warranty. I stated dealers could do the same as in provide their own warranty just like Dinan provides their own warranty. Your analogy may be correct in your mind but it was not the one I was drawing.

        What could also happen is somehing like what Dinan has with certain dealers that are approved dealerships. Reason being Weistec should not simply provide a full warranty across the board as some guy installing this in their backyard might make a mistake and it would be illogical for Weistec to be on the hook for it.

        Interesting. I forgot about the Dinan dealer relationship. That would be cool if Weistec did in fact have a limited number of "approved" dealers to install the Stage 1 and they also issued a limited powertrain warranty. I'm sure that would be a big selling point for new car buyers and really...how many Stage 1 failures do you honestly think there are gonna be ?
