    [FZR 09] Impeller suggestion - I'm too slow

    Hello all.

    First my setup:
    1. General informations
    • FZR SHO 2009 with 89 hours
    • 98 octane gas
    • Dean's LVL 5 tune
    2. Injection/Air
    • SVHO injectors
    • Fuel Pressure Regulator Kit
    • Custom made intercooler with 4 piping (at least comparable to Fizzle)
    • Tial BOV Q 50mm
    • K&N Air Filter direct on the compressor
    • Intake Manifold Upgrade Kit
    • High Flow Fuel Pump (AEM 320LPH) with own circuit and real 12V
    3. Pump/Hull
    • TBM Pump Cone
    • WORX Sponsens
    • Riva Ride Plate
    • Water Intake Grate
    4. Engine/Supercharcher
    • Carrillo Connecting Rod
    • Valve Train Upgrade Kit (springs and retainers)
    • CP 9.5:1 Pistons
    • E1 wheel (16psi @8000 according to manufacturer)
    • Free Flow Exhaust Kit
    • Iridium Sparks
    • Engine Breather
    • Intercooler Cooling Kit
    • MTX-L Wideband Digital Air/Fuel Ratio Gauge
    I hope I haven't forgotten anything.
    Actual speed only ~130 km/h / 80mph (garmin gps).

    A mysterious part: the impeller!
    I don't know which impeller is installed. The dealer said that the previous owner had used a different impeller. But nobody knows which one.

    --> Which impeller should fit for this setup?
    --> How fast should I be with this setup?
    --> Should I change anything else?


    Thank you in advance

    Ditch Riva ride plate its slowing you down.
    Ditch the Riva E1 wheel get a ET 18 wheel, E1 shutters at higher rpm.

    14/24 would be okay and if 160mm a 13/19 would work.

    Need to know RPMs your running, current pump size 155 or 160mm, and your Air fuel mix...

    You're right, the important things are missing.
    - Stock 155mm
    - 8800 rpm @WOT
    - AFR not sure. Around 12.2
