    Ski Doo xm 800 turbo with powderfreaks head

    when i first ran the kit years ago i ran tdr turbo reeds but the bottom end sucked and i bent one reed cage slightly when i hit rate of increase to hard and had a huge back fire. tdr reeds were fine those things are indestructible but they are too stiff and don`t seal completely. once i figured...

    Ski Doo xm 800 turbo with powderfreaks head

    yeah that's so far off being that light on pin weight. no wonder you blowing more reed cages than a hooker in a back alley. way to light pin weight. turbos need load not only to help control your rpm but load makes heat and heat spools turbos so the more load you have the sooner and harder your...

    Oil reservoir

    upper and lower rod bearings are the only thing that would see extra oil from adding it to the fuel on a secondary injector setup like what you run on a turbo sled. in stock form mixing oil with the fuel will never hit any of the rotating assembly and is a waste of oil and time on a direct...

    no one shares this i had to figure it all out myself too. did so much reading back in the day with very little luck. lotta testing went into getting this thing dialed the way i wanted. im also very picky on the way my **** runs. so you make one change and you go test see if you made a positive...

    Tra 7. Tra 3 is from way back. Top where the pin goes with the roller does top end rpm but also effects all areas but mostly top. next hole down does mid range rpm and bottom hole next to the lever axle that mounts the arm to the clutch does bottom end rpm. there is some overlap between areas...

    rate of rpm increase protection is there to try and protect your engine when you blow a belt, it retards ignition timing heavily to stop rpm increase so you dont twist a crank when your engine goes from being heavily loaded to unloaded when the belt leaves the building. unfortunately when you...

    Oil reservoir

    This will do nothing and is bad advise. Etecs are direct injected mixing oil with the gas is pointless as it will never see the crank or wrist pin bearings as fuel is injected above the pistons right before it is ignited with spark. all you are doing is burning extra oil in you combustion...
