With the 3 series traditionally having the largest aftermarket support of any BMW model, it usually doesn’t take long for the first aftermarket parts to become available. And one of the first parts are usually suspension components.

The H&R Sport Springs (Part #28878-2) lower the F30 by 1.2″ front and 1.2″ … CONTINUED

We bring you the first dyno results from a 2012 335i (F30) sedan, performed by Challenge Mfg. USA (GTM_Challenge) on their recently delivered 335i. The F30 335i is powered by the N55 6-cylinder TwinPower twinscroll turbo engine and its factory quoted power figures are 300hp / 300lb-ft.

The 335i N55 dyno run resulted in 270whp and 273lb-ft torque. Note that the dyno was performed on a AWD Dynojet with linked AWD rollers. On a normal rear-roller-only system the numbers would be slightly higher (probably 5-10hp) given the … CONTINUED

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 … CONTINUED

What does this equal to at the crank … CONTINUED

BMW’s new 2.0L 4 cylinder turbo engine (the “N20″) may be down on cylinders and displacement compared to the inline 6 cylinder (N52) that it replaces across BMW’s model range, but even in factory form, it matches the outgoing N52′s horsepowers and features an extra 30 lb-ft of torque (in the X1 xDrive28i, X3 xDrive28i, F20 128i, 528i, Z4 sDrive28i, and upcoming F30 328i).

And what the N20 loses in smoothness and top-end pull compared to the outgoing N52, it now looks like it will easily make … CONTINUED
