As a followup to the F80 M3 Dyno and Weight article from yesterday, here is another BMW M3 and M4 going to the European Auto Source dyno. This time the
Cafornia-based EAS had an opportunity to once again weigh another M3 for comparison. The folks over at Racewerkz Engineering swung by EAS shop with their new Mineral White F80 M3 and Alpine White F82 M4.
Naturally, the first order of business was to see how the M4 would do on their in-house Dynojet dyno.
Just like the Yas Marina Blue M3 they dynoed last week, this Alpine White M4 further proved that BMW has seriously underrated the F80/F82 horsepower claims.
Even on a relatively hot and humid day for SoCal, the M4 recorded a very impressive 421whp and 410wtq with STD correction.
