    Confused on what SC upgrade to go

    I am still confused with SC to get

    I am running a Riva Stage 1

    I dont know if I go with Green Charger , Riva S3 or Rotax

    I will intend keeping stock intercooler though

    Any thoughts please

    i would do the vortec one becuase imo the stock IC is not efficient enough for the larger wheels making more boost...stock IC and Stock Injectors

    like shibby said, keep it stock and ride it

    I couldn't disagree more. Even though the more boost you make the more heat you make there is still a benefit to running the higher boost. JD 1 has even run Rude Chargers with stock intercoolers with tremendous results.

    Here are the impellers starting from weakest to strongest

    Riva Vortech
    Rotax Racing
    Green Charger
    Riva Pro Series (stage 3)
    B kit
    Rude Charger

    Green wheel is best bang for buck IMO. (take it from the only guy running one right now) You will be happy you bought it. And with the sale of your old Vortec wheel, you wont be making a major investment.

    On my 06 RXP with just a 4in intake, RR SCer impeller (9.6p.s.i.) and a Solas 15-20R. I run All over 73 with as high as 74.

    So you be the judge.

    Is that not to much prop for that set up ? Is it sluggish out of the hole by any chance?
