With cooling the air before the blower the problem is now the air will get hot from the friction of the vanes. Detroit 8v92 is a good example also. Inter cooler is below before air enters engine after turbo. Another example would be a GMC Typhoon or Syclone as how they are inter cooled. No room under hood to clear so they had a good idea how to fit it in. You need to cool air after the turbo or the supercharger.
