M3 Eisenmann Dyno
Here's an M3 Eisenmann Dyno... Can't find one for an X5...
The numbers achieved were very impressive indeed: the M3, equipped with the factory exhaust system, achieved 351 wheel horsepower, a very realistic number when considering the car's 400 crank horsepower rating, and the repeated runs that corroborated this number. This M3, when tested with the Eisenmann system only an hour and a half later, produced 364hp at peak- a 13hp gain! Even more interestingly, 100rpm earlier, at 7900 RPM, the Eisenmann system produced 363hp, while the factory system only allowed the car to produce 348hp- a 15hp gain!
