I doubt Mopar or anything associated with Chrysler will come out with an upgrade supercharger. The SRT (amg) version has not only a supercharger added, but injectors, ecu, lower compression, better head gasket, forged internals, etc.

If you just slapped on a supercharger, ecu, and fuel, the bottom end would still be weak and at a higher compression, you would have to run less boost. Basically you wouldn't see the HP numbers the SRT does, and it woulnd't last as long either.

Now purchasing the SRT and changing out the pulley, upgrading exhaust, intake, and fuel, adjust the trims, more psi. I don't see why you couldn't squeeze out 400hp

Ok now I remember why I got the coupe. I've already wasted enough money chasing the never ending HP / TQ pipe dream. It is only as good as the day you put it on. Then you start to break ****
