    Try an out of the box 15/20r stage II Riva prop and dial in accordingly (if necessary).

    Danny was running something close to that..He had stock injectors and SC wheel with a external IC..He was running a 15/19 3 blade with some tweeking.But you have the adjustable nozzle so adjusting your Rs should be easy..He was running mid 70s with that setup

    Doc, I am running a stage one plus xs cooler and a Riva rear intake. Very simialar to what you have. I am seeing 8180rpm w/ the 14/19 at 73.2 mph. Put the IC on and if your revs are near were mine are try a 15/20 and tweek to keep rpms near 8100 and youll see 75!!!

    Jfizz suggested I add 2mm to my 14/19r not take away, sound right, hes running a more elaborate setup than mine but knows about tweeking.

    Doc,that last post was aimed at GOLD06.sorry for the confusion


    Sorry didnt mean to step on any toes but if you bend the blade in toward the hub of the prop 2mm your Rs are gonna be even higher..You would need to bend the blades back toward ths say bottom of the prop to drop your Rs..1mm usaully =100 Rs..But you wont know till ya try..


    I guess i should have said increase,"not pull a mm out" My bad
