These dyno fails wIll make you want to strap down extra tight next time you hit the rollers

Gearheads love dynos. It’s as much a part of the automotive culture as actually lining up and racing. With many performance shops installing chassis dynos, there are likely thousands of pulls made each week across the nation. With that many runs taking place, there are bound to be some mishaps. In this Top 5 video, we get a close up glimpse at a few of those not-so-fun experiences.

The first couple of clips are sobering reminders of the importance of double and even triple checking your tie downs. Tie straps are the only thing holding your precious hotrod in place while you’re running through the gears on the dyno, so you want plenty of them and you want them to be TIGHT! These end relatively well considering how badly things could have gone, but keep these clips in mind next time you pull onto the rollers and ratchet down those straps.

The top three clips are a different kind of failure altogether! Number three and two look to be good examples of what happens when you push your car a little too hard trying to nudge that dyno graph as high as possible. In both clips the power plants decide they’ve had enough just before the runs are over, leading to pretty spectacular engine failures. And the number one clip shows what happens when the dyno itself gives up the ghost at speed, sending sparks, parts and spectators all scattering. After watching this video, you may find yourself watching dyno pulls from a few steps farther away in the future!
