^^ kinda true kinda not it is true in most cases remember a turbo is more a compressor then just a fan by design, but a vacuum cleaner is an example where it can suck and hold a vacuum also on my shop vac if you put your hand cupped on the outlet side it will continue to blow and hold pressure that all depends on electric motor hp & fan / pump design. there is many more examples but to expect a 12v 1/20th HP CPU fan to hold 10lbs of PSI is B.S. infact the fan would impede the engines air flow at full throttle and the force would be so great on it it would suck the plastic fan blades off into the intake.
The Turbine does take & impede the flow of gas at most a turbo will rob 4-5hp you can confirm this by experimenting i could provide facts on how to do this but trying to keep this short.
The point is the turbo is taking the 4-5 HP gained by using exhaust flow and compressing the air coming into the intake to release a lot more HP
You can do the same with an electric motor but the motor would have to be at least 10-25hp you would need 4-5 120 amp alternators just to keep a electric compressor motor running it would have to be verry large not efficient if you ask me. So far current turbo/turbine designs are very efficient!
Doesnt matter what you call a turbo its a turbine at the heart of it!

By the way the holset hx35 are cheap and last longest doing this!
