Something has to make the turbo or supercharger spin. For the turbo, it is gases produced as a by product of combustion. Might take a few thousand rpm to build the boost but it isn't robbing power. Think of the supercharger as just another accessory that the motor needs to spin. The water pump robs power, so does the alternator and even the power steering. Since the supercharger is belt driven just like the rest of those components, you will be losing some hp.</STRONG><HR></BLOCKQUOTE><P>The turbo still robs power from the engine until the turbo spools. Usually it's not noticable but it still does. Like you said SOMETHING has to spin the turbine. The turbocharger may be using lost power out the tail pipe, but it still robs power due to increased backpressure directly out of the block. Like I said, it don't take enuff to make it less efficient than a supercharger, but still. Not to cause any debate, but I don't think it's fair to use "parasitic loss" as a deciding factor to get a turbo when it also has that parasitic loss itself. If my knowledge is inaccurate please feel free to correct me.

Therefore, how is using something that was wasted in the first place a parasitic loss? If you look at the powerband of a turbo car, at NO RPM point will the power curve be less than stock. <P>Your knowledge is inaccurate, you have been corrected.

HAHAHA, how did I know it would be you that would reply? <P>I know I read somewhere about the parasitic losses of a turbo. The way I see it if you stick something in the way of the flow of the engine, be it intake or exhaust, it will put a negative effect on power. Hence if you stuck a banana in the tail pipe.....car don't run. I guess my source of info was wrong.

Hey guys.. How would a Supercharger running 6 to 8 PSI on a KLZE doing 50 miles a day effect the engine?

there's probably about a thousand other variables that need to noted before anyone could even consider answering that. you never mentioned type of s/c, cooling, efficiency, daily driving habits... etc etc etc.
