    Rave Valve 101

    I was trying to find a good article/ tread about the rave vales and how to set them up. Can someone point me in the right direction. And if it's not on this forum, maybe one of the Pro's can explain how to set them up correctly.

    On the 951's, they are supposed to be screwed all the way in. I wouldn't worry about adjusting anything, just make sure they are clean and working properly.

    Red adjuster caps all the way down = powerband comes up later, all the way out = powerband comes on sooner.

    Waterbox Valve is a balance between the Engine Raves and WBV to get the water injection to taper off at the same time the power band from the Engine RAVES comes on.

    Try a few different combinations, there isn't too much difference on a stock engine.

    Would there be any diference on a Lvl 1 PPG engine like mine? And by changing the water setting would you risk over heating the engine?

    The position of the red cap on the water regulator (on the waterbox) won't make much of a difference on a stock XP-L or a PPG Level 1. You cannot hurt anything by ajusting the red cap on the water regulator. Try a few different settings and see what seems to work the best. Again, you won't see any major differences just a slight difference in where the power comes on.

    To little water to the exhaust and you will melt the hoses/couplers, and the plastic resonator in the exhaust system. There isn't enough adjustment in the red cap on the water regulator to cause this.
