    ^^^I don't think it's as much that people don't know what CFM is, but more like they don't know how it affects power output.

    Like George mentioned, if you take a BIG turbo @ 10 psi and compare it to a little tiny stock turbo @ 10 psi, they very rarely put out the same power. Why? Lots of reasons, but first is probably the amount of air one moves vs the other. Both may be at 10 psi, but the bigger turbo flows more air (volume wise) and therefore usually has the potential for more power overall. Also the efficiency range is quite different. A big turbo @ 10 psi may not even be breaking a sweat, whereas a tiny turbo could be close to being maxed out @ 10 psi and is really pumping nothing but hot air.

    Please don't flame me on the numbers as they are stricly hypothetical.
