Monday is for M: 633-WHP BMW M5 Bullies the Dyno

It probably takes hundreds of thousands of horsepower to kill a dyno, but as cars like the BMW M5 get more powerful, (especially when tuned) you begin to wonder how upset the dyno must be as it gets a wallop from a pair of rear tires.

In this week’s edition of Monday is for M, an F10 M5 flinging 633 cracked-out horses to the wheels gets strapped to the Dynojet dynamometer at European Auto Source.

How did this particular 2013 BMW M5 get to 633 rear-wheel horsepower? Quite simple, really. All it took was a Switzer tune, AMS catless downpipes, and Akrapovič Evolution exhaust.
