    Is upgrading to a TURBO worth it? I'm looking for more power and speed...

    I have a 2005 RXP with Stage III with a rude 3 supercharger. The ski hits low 80's now, but I want to go much faster, will a turbo do it? Is it worth spending 5K on a turbo kit? What I can expect switching to a turbo for hole shots and top speed compared to a supercharger? Thank you...

    I don't think your going to get 5k worth of additional speed.
    I'd say save the cash...

    Sell the components you won't be using to offset the cost of a turbo kit.
    Definitely worth it if tuned correctly.

    That's what I figured, but how do some guy's get over 90 MPH?

    With that rude 3 and the right set up you should be mid 80s. If you want turbo by the time your done you going to need more than 5k. IMO

    90 is possible (from what I've read) with the correct hull setup and a good pitch/nozzle combo.
    Duke is said to have built a 100mph rxp, but he's quite skilled.
    Good luck!

    turbo is closer to $10k
    a turbo can brake more than just your bank
    r3 is 20psi @9k and turbo 20psi @ 7k and 90+mph
    even a small turbo like a 2871 will make 400+ easy

    depends on your definition of "worth it". hole shot and top end will be a bit different...it will pull like a freight train mid range and up top, but it will have some lag out of the hole. wanna go faster? turn up the boost

    a 2871 will build boost by 5k about 5psi by 6k maybe 15psi

    you could hit 20psi by 3500~4000rpms depending on the size of the turbo. something small like a 28 series should see full boost (20~30psi) by 3000~3500rpm. by lag i mean the snappy response of the s/c vs the vacuum to boost transition of the turbo.
