This is a pretty cool video. This guy mounted a GoPro in his engine bay by the turbo to get some video of it and also one at the back of the truck for the exhaust noise. Talk about getting hot real quick. But it does sound real nice
And this is where proper turbo etiquette comes into play. People need to make sure after going out and putting that turbo to work, you need to let it cool off for a few minutes when you bring it home before turning it off to ensure optimal turbo life.
Seen videos of engines themselves being put to the test on dyno's, after a run some shops would turn off the lights to really give a look at the light given off from all the heat generated. I'm sure if that was the case here we'd see part of that pipe heated up too.
Some high performance systems get so hot they turn purple
