When you add power to a vehicle, it's wise to beef up certain components. If you continue to add more power, you should begin figuring out exactly where you could have issues due to the increased horsepower and torque.
For example, if you're building a track car with serious power, you're going to need to upgrade the brakes to haul that oomph back in before each corner. If, on the other hand, you're creating a monster pickup truck designed to decimate dragstrips, you may want to invest in a beefier driveshaft.
We're looking at you, Dmitri Millard.
This is a man focused on making his 2001 Chevrolet Silverado one of the fastest trucks at the track. He recently (per the video upload date) had his truck Red on the dyno for some testing and tuning. According to the video description, Millard had run a good number of passes with the truck producing well over 1,300 horsepower. This equated to 175 mph pulls... and serious stress on the truck.
After one more pull, the driveshaft decided it was going on a vacation. Thankfully no one was standing in a stupid spot, and the only destruction happened to be of metal and not of man. Regardless, the video is kind of hilarious, even if we feel bad for poor Red and Mr. Millard. That's what can happen though, when you start going for insane power figures.
