Detonation.
Boost creates cylinder pressure and what is referred to as "dynamic compression." Plus, intake temps are higher due to compression air which makes them more prone also and is why people run intercoolers. The big turbo guys running at a quarter mile or eighth mile track are running ice water in the intercoolers to get intake temps down. Also probably running 30+ lbs of boost. I'm sure there are people who are better able and are willing to go more into depth whom may chime in.
Not read his book ,but the Corky Bell whom did my supra wrote a book "Max Boost." Corkly is right up there with Detwhiller (sp) and da boys and I'm sure he answers it a thousand times better in the book.
