California-based tuner EuropeanAutoSource hosted a Dyno Day this past Saturday where 22 BMWs showed up throughout the day to put their engines to the test on their Dynoject 224xLC. The day started at 8:00 with the temperature already in the low 80’s, and ended at about 5:30 in the high 90’s!

“Regardless of the California heat, the cars performed well and everyone seemed to enjoy the show, food and the friendly competition,” said Tom of EAS.

Most of the cars that showed up were M3s, but to everyone’s surprise, a new F13 M6 Coupe made an appearance as well.

The winner was Zach with his ESS VT2-600 supercharged matte black E92 M3 rated at 562hp.
