Regarding having to run at high RPM to obtain boost, my old Toyota 4x4
came into boost at 1800 RPM. And that is not WOT.

A turbo is more efficient in that 1/3 of the fuel burned goes to power, 1/3 to heating & cooling, and 1/3 out the exhaust. So, in theory if you can use the 1/3 that is wasted out the exhaust and re-use it you are increasing the efficiency of the engine. And, yes of the 1/3 that goes to the exhaust some power will be lost do to turning the turbo and the increase in operating temps. A friend of mine has a BMW M3, a very nice CAR, he showed me this www.bellengineering.net/BMW/M3turbo.htm it is some good reading. But remember this application may not be true for all vehicles. I personally will be getting a s/c for my Durango. It is my daily driver and would prefer not to have my engine operating at boost under low RPM's, such as cruising at highway speeds. I like the idea of having boost at 3,000 RPM through 5,200 RPM. So, when!
