    Give me your thoughts on my modded 4tec please guys

    SEADOO RXP 215 2004

    Engine has a ported head, valve retainers, WSM valves standard everything else. Runs a les cooke supercharger wheel (red anodised) straight through exhaust, xspower remote intercooler with a RIVA power filter. Rotax racing ECU with rotax racing throttle body a few mm bigger. At present standard injectors.

    I do have other injectors to put in (see my injector post) i beleive standards are 38lb? I need to know the purples size plus i have some 50lb ones...which should i use out of the 3?

    Also i apprently bought a riva stage 3 supercharger but it didnt go as quick as what it does with the les cooke supercharger??Plus the les cook one really makes a chirping where as the stage 3 didnt?

    Attached is the pic of the comp wheel in the supposedly stage 3?


    Does there look any problems here? Runs fantastic, any idea on power?

    No nothing! I bought the ski as the same setup but on a different ecu but that failed so now i have had this ecu put on, runs great.

    nope..

    Looks like a standard 215 SC that wasn't taken care of judging by the rusted bolts and not having the 4 add on bolt holes.

    Bosch Man. Search the threads here and read. READ my friend!! BTW if you actually have a ported head who did it? There are very few people actually "porting" and doing it correctly.

    My head I did personally. Technically every head you remove material from is ported but all that should be done on a low boost head is smooth/polish the mouth and throat of the ports and remove the casting slag on the exhaust side as well as blend back into the bowl. You run past X then talk to Slow.

    Definitely not a 215 wheel. Too many blades

    no way to know for sure without removing the front cover and measuring the wheel.
    It could be a riva S3 wheel upgrade. {127 wheel upgrade and cover. }
