$9,500.00 is pretty expensive for a little over 100 hp. With simple math > 95 bucks per 1 hp. That doesn't include installation or at least a hug. I still think a STS Turbo system would be the way to go! When you buy the Mercedes name > it is not cheap and not worth the badge either. Quality is important > but not that hard to find! I was wrong in my other post > I didn't think the charger was a roots style (twin screw). They make HP at low RPMs but lose steam when others are just getting started. Look at the attached pic. This is some good reading!!!
