    When you say S-Charger, do you mean an S3? Because the S3 charger and the X-charger are two different sized chargers. The X- is bigger then the S3 which uses the 215 housings not the X-housing.

    s3 is what im toldm, it was sapose to be like a
    green hulk but it is riva, at best what psi would i be looking at if its an s3?
    what psi does it take to go 79?
    the numbers on the case are 867 151 any ideas on that

    greenwheel=Riva Gen. II 8.5-9 psi 127mm diameter
    riva s3 9-9.5 psi 127mm diameter good charger you can run with 42# injectors and external IC and you do not have to monitor AFR or use RRFPR
    x charger 10 psi 130 mm diameter=more volume Requires RRFPR and a way to monitor AFR

    "S3" is slang for the old Riva stage 3 supercharger upgrade. It was 127mm and has sense been replaced by the 255/260 X model supercharger and Riva XX upgrade.

    You can put the charger but it will require other mods....Also if it's just the X wheel then you will have to machine the housing.
    You do NOT need an rrfpr to run an x charger unless you put an external intercooler. I'm running an X charger with 42's and it runs fine.

    Greenmonster, what year is your ski and how fast does she go
    what pitch prop are you running,
    i was reading on here about oiling upgrades for different chargers
    from different years this is confusing
