    Whats the reasoning behind the holes in the compressor housing. It seems turbonetics uses them the most.

    To combat compressor surge, slows spoolup slightly, a big help if you are close to the surge line.

    speeds up spool..
    allows re circulation of compressed air , to exit back outside the comp cover, in surge
    slightly reduces max flow output of compressor
    makes wicked spool up noises :2thumbs:
    lightens comp cover

    This is the man you want to listen to. If he says the sun is black I'll believe it.
