    impeller pitching to match rude 1

    i have 2004 rxp with 15/20r 4 blade solas impeller. i was basically running riva stage 3 without ecu. i just installed my rude 1 supercharger and #50 inj. i was running 8150rpm with 81mm nozzle with my old setup. how much should i tweak my impeller to accommodate my rude 1 charger (2psi more at 8100)

    I would try 1mm to start and see if youre still on the limiter, best way is trail and error until satisfied. Read it somewhere here... ''small changes are making big results''

    I jumped up from a greenwheel to a Rude 1 and have the same prop, I would love someone to give me the correct trailing edge mm from bench to blade bottom to save me tweaking it a ton.

    No No No..My bad..I read it wrong..I thought thats what your getting with the Rude 1..I would go at least 2 mm to start..Then get your RPMs and fine tune it from there..
