Mitsubichi Lancer Evo Dyno Fail [Video]
However, as we are talking about forces with high values here, it’s really important to follow the “safety first” principle when playing with a a dyno. We know one could be tempted to follow the urge to put the vehicle to a test and enjoy the soundtrack while waiting for the results, but cutting certain corners could lead to serious problems.
We’ll use a painful example to demonstrate this. We are talking about a Mitsubishi Lancer Evolution VII, which got hurt during a dyno run. According to the uploader of the Youtube video, a group of students from the Mech-Tech College in Ponce, Puerto Rico, were eager to see exactly what the Evo was capable of using the school’s dyno, when thing went bad, really bad.
The dyno runt started as any “event” of this kind, but at one certain points when things were getting really hot, the Evo started moving to the right and slipped off the dyno, damaging itself and the power-testing machine. It seems like the vehicle hadn’t been properly strapped (there’s a long discussion about this on the EvolutionM forum). And you don't need to be an automotive engineer to realize this - you only need to take a close look at the footage to see that, for example, the vehicle's front end hadn't been strapped.
However, there is one good part of the story. It seems like the unlucky Evo, which had received a number of modifications, managed to show show the dyno that it can deliver 450 hp before it left the scene.
