Here's the telltale proof. As Huh, me, and others have repeatedly 
pointed out, you are confusing absolute compression with the 
compression ratio.  You use the ratio below which makes it unambiguous. 
  Detonation is not related to compression ratio. It is related to 
absolute pressure. PV=NRT, and its the T that gets us every time.

Forced injection engines, as I stated before, put more air into the 
same space.  Its not rocket science.
