Well guys, I finally got an answer to my question. Can the Xfires clutch, transmission and rear end handle the supercharger hp boost? Putting out big bucks for a supercharger is one thing but what about the rest of the power train?
Just got an e-mail from Cory Umenoto, tech manager at Kleemans and he said that they have modified a number of SLK320s (same as Xfires) and the Xfire power train can handle 400 lbs./ft continuous torque. He said that they have had 0 failures. Pheww! You gotta like it! OK so who is going to be 1st to make a supercharged 6 speed?
