but then in the city i wouldn't use that much of the high-peak power. rite?
assuming you have a manual, that's entirely up to your decision when to shift
a s/c would be better for efficient city crusin' because it gives you hp at low rpms as well as the high - by efficient city crusin' i mean shifting before you reach 5-6k rpms
a Turbo will be better for racing since you're going to be revving high, assuming you want to win the race
eh i drank too much coffee sorry
basically, the ammount of "high-peak power" you use, is up to you.
edit: if you have an automatic, a s/c might be better for your application.. not sure how or when automatics decide to shift, or what rpms they rev to before doing so
