    Not really. What mods are you running?

    The previous owner told me the supercharger bearing went bad
    and damaged the compressor wheel so he had the supercharger
    rebuild with a 255 supercharger rebuild kit. Don't know if there
    is such thing. I'm guessing he just put a bigger compressor wheel?

    The supercharger rebuild kit is the same for 215/255/260 HP applications. This is the kit

    I'm sure he didn't put a 255 compressor wheel in the supercharger. He would have had to machine the housings to make it fit.
