As you may already have seen, a member recently took delivery of his 2012 328i (F30) sedan and wasted no time in getting it strapped to the dyno. The 2012 328i sedan is powered by the twinpower twin-scroll turbo 4-cylinder inline “N20″ engine, factory rated at 240hp / 255lb-ft torque.
This F30 328i was tested on EAS (European Auto Source)’s Dynojet 224xLC and put down an impressive 226hp / 230lb-ft torque (at the wheels), with just 91 octane gasoline.

Assuming a 15-17% drivetrain loss, this dyno result translates to approximately 265-272hp / 270-277lb-ft torque at the crank, or +25-32hp and +15-22lb-ft torque more than the factory figures!
