The first step in developing our F10 M5 project car is gathering baseline data. In the upcoming weeks IND will work to gather information from the dynamometer, the drag strip, and a local road course.
527 wheel hp
Today we visited AMS Performance, our technology partner for this project, to dyno test the M5 in stock form. BMW does not fail to impress, as the sound and performance of our M5 during the dyno test was stellar even before we installed any modifications!
The M5 roared to life on AMS’ dynojet with a mere 450 miles on the odometer and we looked on in anticipation. The original exhaust is somewhat conservative in sound and tone but the S63tu engine did still create a promising roar as our M5’s wheels spun the dyno rollers for the first of what is sure to be many tests. We were excited to see that the M5 performed flawlessly, even after 40 minutes of dyno runs. Best of all was of course the power number- 527 wheel horsepower!
Of course, a power output figure is not relevant without weight! As an added bonus we set the M5 on AMS’ Longacre scales to get a good real-world weight figure. With a half a tank of gas our M5 weighed in at a “stately” 4,313lbs! We will be addressing the car’s weight very soon.
We performed datalogging of intake air temperature, throttle position, boost pressure, engine oil temperature, and water temperature to start. We will continue to gather data as we test the M5 and will use the information to further develop and perfect the super sedan. Stay tuned for updates!
