Single Turbo Blow through Small Block Kits???

Not that I'm anti turbo, but.........

How much power does it take away from the engine to spin that turbo?

IF the turbo has to pressurize the engine, the impeller has to have some force put on it in order to spin it to make pressure. Once the engine is under prssure, there has to be more force required to spin the turbo in order to maintain pressure.

This is back pressure on the engines exhaust side. This has to cost power in some way shape or form.

It really doesn't work the way you think. Off boost a turbo system is very free flowing they have to be or else they would be even more lag than usual. If you have a properly sized turbo setup you will have some lag, You will never notice a restriction off boost even with a back pressure gauge. And when the boost comes on you'll never worry about that again :)
