    Rotrex C38 series supercharger technical specs and compressor maps

    Thought guys might want to look into this and maybe compare the HKS blowers: http://www.germanboost.com/showthrea...TS7040-GTS4015

    @DBFIU can you convert the max flow numbers into CFM? Math isn't my strong point:

    Yes compared to the other blowers and HKS catalog but still seems much smaller than Vortech and Procharger offerings.

    rotrex C38 91/92 flows about 1100-1200 SCFM max which is respectable
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    "Note- The C38-92 is the same as the C38-91 supercharger with the exception that it has a 90mm (3.5") inlet diameter instead of the standard 70mm (3")."

    I wonder what kind of power difference that makes. Probably not worth the upgrade from my 91 Trim to the 92 Trim.

    I believe Evolve said they tried it, and no difference. I believe its just to alleviate sizing differences for some applications

    That makes sense. I am kind of glad it isn't an "upgrade" because I know I would swap out my current 91 Trim for the 92 Trim even if it was like a 2% gain haha
