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''

pulling that thing out and tweaking is a pita, i'm trying to find maybe someone has it done already so that i can know ballpark. and finetune with the adjustable nozzle

says on your sig that you added 2mm, is this correct?

your gonna want to start with at least 2 mm and go from there..You wont know how much to tweek it till you get your RPMs..

i was afraid so. i was thinking maybe going straight to 2mm and adjusting with nozzle, would that be good?

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..
