Insideline recently strapped the 2012 328i with its turbo 4 cylinder N20 engine on the dyno and achieved even higher at-the-wheel power than the EAS Dyno we reported on recently.
On 91 octane and a dynojet, this F30 328i achieved 240hp / 257 lb-ft torque at the wheels
Assuming a 16% drivetrain loss for the sake of argument, this would equal approximately 286hp / 306 lb-ft torque at the crank. Compare this to the F30 328i’s factory rating of 240hp / 255lb-ft torque at the crank. The 328i could be underrated by as much as 46 hp and 51 lb-ft torque. Impressive indeed!
Compare this to the EAS dyno which achieved 226hp / 230lb-ft torque at the wheels.
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.
What does this equal to at the crank (for comparison to BMW’s factory quoted power figures for the 2012 328i)? 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!
