    Et 127... What mph?

    So I installed a et127 on a 06 rxp 215, stock intercooler, riva stage 1 kit pitched impeller to 15/20 and the ski runs 68@7800... What am I missing... I know I need to bring the rpms back up to 8050 but will that work t give me 5 mph. Customer states it ran 71 before

    Reflash ecu to 8650rpm, external intercooler, pitch prop for 8500rpm and depending on atmospherics you should be in the high 70's

    Stock ic you need to pitch that 15/20 to the right rpm. 14/19 might be a better choice. Should get you in the low 70's. Love that little wheel!

    What intake? I just went through this with my ski? If it's the riva 3" take it off and get a 4" intake. The small intake is killing power

    Yeah it's got a 2 5/8" riva tube, not even a true 3". I have a 4" I can put on and try.
