Vortech makes a supercharger...it costs like $3500+ (something like that, can't remember) but there is a group buy going on right now from (check group buy forum) to get it for around $2500.
With no other mods it'll bump you up to around 300hp. You might want to look into a stonger diff unit and clutch with that type of power though.
I don't think anyones posted 0-60 numbers on a supercharged contour but i'd guess somewhere around mid-5's...? Mistergrym got a g-tech 1/4 mile time of 13.2...pretty darn quick! Probably closer to 13.7 at a strip...but that's plenty quick too!
You should be able to hang with the M5 in the 1/4 after you install a blower...or at least be really close. BTW, isn't the M5 a NA engine? I think it is...
