That video was full of **** for a few reasons......I wont get into all of them. (Note, I own supercharged and turbo'ed vehicles)
But....
It says an advantage of turbos is the fact that it doesnt have parasitic losses because its using spent energy???? Well, thats BS, it takes a significant amount of HP to drive a turbo. People for years claim its 'free' HP.....well its not.
If you dont believe me put a turbo on your vehicle, dont hook up the up pipe and put a few socks in it (to simulate compressor load and prevent overclock)....see how much HP you have.
The video says that SCs are more reliable then turbos....because of fewer parts.
A turbo is as simple as you can get. Take a turbo apart and lay its parts out and do the same with a supercharger (dont forget to include drive belts and pulleys). The reason turbo systems are responsible for more engine failures is due to their relative ease of modifying by the owner. Sure you can put a different drive pulley on a SC but turbos have boost controllers, different gates, intercoolers, BOVs ect. Turbos can also be retro fitted to nearly any vehicle....a SC is typically built for the application. This does not mean that a properly designed turbo system is less reliable OR made the vehicle less reliable.....
The video say turbos can have dangerous boost spikes where SCs do not. Again, a properly designed system with a quality gate placed properly and sized correctly.....no 'dangerous boost spikes'.
(*I could keep going but I digress.....)

Unmentioned advantages of turbos....
Boost is regulated by gate, not RPM.
This may not be a big deal to most but lets look at someone that races in different locations. If you tune a SC at sea level, lets say 25psi at 8000 rpm, and take it to Bonneville (7.5K and 100 degrees = 10,000' air density). Now you are only making 18-20 (est) psi at the same rpm. BOOOOOOO! Because a turbo is regulated by boost, if you make 25psi at sea level you will also make 25psi at higher altitudes (until the compressor runs out of map).
The single biggest advantage over SC on a bike:
Gear based boost controllers.
Because bikes have a tiny contact patch (standard OEM profile tire) it is easy to blow away your tire. It is INSANE to have 500+ HP in 1st gear on these bikes. Because of a host of gear based boost controllers allows infinite adjustable of how boost comes on, making a bike that makes 500 HP streetable (sounds crazy but true).
-lets see a SC do this.......
Turbos also have expandability, bigger intercoolers, water, controllers, gates.....and so on. Not to mention the turbo unit themselves are considerably cheaper (well, this isnt always true!!!).
Again, I own both turbo and sc vehicles. I love them both......but for bikes turbos have taken a 1000-1 advantage for a reason. I am not saying a good SC wouldnt be cool, and more power to ya if thats the road you want to go.
(*mostly the video just pissed me off, and dont believe everything a nice production video has to say)
