i used to have a '06 300c srt8, almost the exact same as the super bee charger just different body style. It was lightly modded and had some weight reduction, now that exact setup pulled on a buddies stage 3 MKV GTI DSG. Granted, my car had about 475WHP and equal torque. They are quick cars stock, and can be really fast modded. the GTI's main advantage is alot less weight, and the fact that they dont have as much drive train loss with a typical standard auto 5 speed trans like the SRT8's do (minus the challenger)
But if it is a stock super bee (new or old) my guess is that you should hang with a new one and pull on an old one
