How is street driveability?
Very good. In fact I would go as far as to say that it is the same as before the turbos. I still get over 23 mpg on the highway, yet have over 500 HP on tap whenever I need it. Turbos do not create boost all the time like superchargers do. They only spool when there is sufficient exhaust flow, which means around town driving is unaffected. Give it half throttle, however, and the beasts will “wake”!
