Just be careful. The guru has made some statements that are not true. One major one is that turbos lag and superchargers don't. I still say if you want a excellent primer on forced induction, read what Mike Kojima wrote in SCC in his Suck, Squish, Bang, Blow series. Mike is an engineer working in both the OEM field and performance aftermarket. He used to work for TRD building racing engines.

For another resource on the discussion, check the SE-R Mailing List archives. They include some excellent technical information about turbos vs superchargers with a lot posted by Rob Cadle, an engineer for Garrett Turbos. Don't think that Rob is biased. He works with superchargers too (for big rigs). Rob and Mike both go into depth about the advantages of a turbo over a supercharger and the popular myths about both.

There are a lot of myths and misconceptions when discussing turbos vs superchargers. A lot of the myths about turbos is based upon old school turbos and turbo systems. I know because I used to believe the myths and know better now.

Lastly I'll say this for now.....

I think you will find turbos to work better in situations with a wider rev range than a supercharger will. That is because a turbo is not dependent upon engine rpm for shaft rpm. So, a properly sized turbo will make boost sooner than a supercharger. Also, in racing where superchargers andturbochargers are allowed, you will find turbochargers. In Top Fuel drag racing you find superchargers because turbos are banned.
