This poll is useless without specifying the car, power goals, and type of usage.
Also, there are hybrid designs, such as the Rotrex supercharger, that is like a turbo on the compressor side.

Dave is the only person I ever met that started out moderate and didnt loose his mind in the quest for more power.
Good luck oh and I have seen GS300's on the board with centrifugul SC's, so they do exist.

Still have yet to see a turbo dragsster break 6s. Long ways to go before top fuel gives up there supercharged set ups
you guys really need to use the search option.

I prefer turbos but they do use power to make boost. They are a restriction though. You need a pressure drop across the turbine wheel. Anything considered streetable will be higher than 1.1 on the turbine side. Even with no back pressure after the turbo you will see 1 psi backpressure before the turbo for 1 psi compressor outlet pressure. I've run some larger turbo with alot of lag and have yet to get below 1.1. The turbo I run now would be considered laggy and is is almost 1.5:1. I don't know what the extra back pressure uses in terms of power but it does cost power to run a turbo.

Turbo's definitely have the potential to put more stress on a motor.
Assume both motors are in same condition, used in the same way and both hit max boost of 6psi. Since superchargers are driven by the crank, boost is dependent on crank speed. This means that you'll have to be at the top of your rev range to produce max boost. Depending on turbo size, tuning, etc, max boost from am turbocharged setup can be achieved at a much lower rpm. So you would be able to experience your max boost of 6psi for a lot longer in a turbo setup than a supercharger setup and therefore inducing more stress on your motor.
The ability of this extra stress is why i <3 turbo.

They are both awesome!
Supercharer...
Give it about a minute, but the intro is a bit long, but WELL WORTH IT!!

Turbo...
This is one of my favorite videos, he even spins the tires on the dyno..

So not true and actually the opposite.
