yeah... that current car of yours doesn't seem to pack the punch for the displacement..... i dont think you'll be downgrading when it comes to performance.... the tC is pretty decent when it comes to power... and with the low gearing in the 5spd you can jump off the line, and find youself going 90 with out even trying....
as for the reason why autos seem slower is because they slip.... manual transmissions slip too.. but you control how much it does with the clutch pedal... so if u pop the clutch.. you can jump off the line faster... so i guess manual's are faster in that aspect....
dont know anything about superchargers other than it makes the car go faster....
hope this helps you a little... im sure lance will come here and correct me and provide you with better anwsers
