    Turbo questions:

    So I have decided to go turbo on my GPRXP and bought DinoMite's turbo.

    Few questions:

    What do you do with the supercharger squirter? does it need capping or just leave it to spray as per normal? Would imagine without charger-shaft there, it will just blow all over the starter Bendix.

    What is the best oil to be running?

    What is the best cam for turbo applications?

    Mine is snipped so the oil return plug can clear then crimped it off.

    Ive got a brand new still in the box stage 2 billet cam I bought from GladeRunner. Same one he is running. He just went 90 on his tx260 same turbo.

    I run Royal purple 10-40.

    You lead me astray, lol

    I might end up having a cam off you in the near future

    I am tempted to remove the squirter and install a fitting to block it off then why I have the PTO removed..

    What bearings do you speak of? There are no more clutch surfaces that need to slip on each other once you remove the supercharger.

    I removed the the supercharger oil squirter and blocked it off with a small bolt. Sorry, don't recall the size.
    I'm using AmsOil racing oil 15W/50. My second choice was AmsOil 20W/50. Others use Valvolene 20W/50.
    I installed a Stage 2 Colt Cam. No regrinds for my ski.

    The mid range and top end with a gprxp is insane ... yr not really going to need a cam ... (sorry shoot me now) you can put a bolt or washers inplace of oil squirter . Or bend it out of the way ... i used a bolt ...i would recommend a 160mm pump
