Turbos at Altitude and a great book on turbos (technical stuff)

[EICHSTEV@aol.com]

With all the talk on turbocharging theory lately (much of it incorrect IMHO),
I thought I would let you know of a book I found a while back.  Its called
_Automotive Supercharging and Turbocharging Systems - A Technical Guide_, by
John D. Humphries.  Its available from Motorbooks International at  1 800 826
6600.  I found my copy at a local book store.

The book goes into a lot of theory, but is readable for the non
aerodynamicists.                              
There's even a compressor map from KKK on the Audi I5 w/ K26 - interesting
stuff . Unit descriptions are in German though not difficult to figure out
(especially wenn Sie Deutsch sprechen).   

The Turbos at Altitude thread can use some of this info.

Happy reading!
