    RXPX: 8120rpm - Stock Limit?

    I've done the 4" intake and work grate, I didnt see 200rpm increase, was like 8060rpm before and now 8120rpm. Is that the stock limit?

    Food for thought:

    Seadoo reps have said the stock ecu pulls timing after 8000rpm. So ideally you should be pitching for that.

    but on the other hand, like frankie, others have hit their best speeds at 8160.

    I dunno where you ride, but up in the northeast I pitched for 8060 in the spring i ran 7940 in the heat of summer and 8160 in the cold fall.

    You and many others say this but I have ridden my boat and it personally feels the best around 8120-8140.

    I have never noticed it knock me back down yet and Im assuming because I have never hit 8200.
