    Removing the OPAS?

    Hey guys, i was on rivas website just looking for stuff to buy to mod the ski a little more, what is the opas removal/block off kit going to do for me? is it even worth it? I have the stage 1 kit but of coarse i am always looking for new mods. By the way my ski is a 09 rxpx.

    should be looking on jerrys store for parts! as you go faster the pro series block offs or R.E.'s will help keep the ski from bouncing at higher speeds

    The reason I look at riva is because i get dealer cost there, i have nothing against jerry. But i was just wondering if i remove the opas will there be less drag on the ski at top speed?

    IF your just stage 1 I would not mess with ditching the opas, unless your wanting to run thru hull exhaust or if you dont like the ride with opas or if your looking for tenths.

    Get the mini rude supercharger upgrade. It will out perform all other X charger upgrades.

    Then install 48 lb injectors and a rising rate fuel pressure regulator.

    You will need to add some pitch to your 15/22 to take advantage of the extra power you will be making.
