    My GTI 260

    Hello guys,
    I am finishing to install a 260 hp engine in my GTI hull.
    I have added a rotax racing intercooler and a Riva XX supercharger kit.
    I need some advice for making my choice for the impeller.
    For the moment I have the stock ECU but I plan to add a Vtech tune in the next months.
    Could you help me?
    Thanks

    you will need bigger injectors to go with the bigger SC wheel
    15/22 if you dont upgrade the valve train

    Hello skidoochris,
    Are you sure I need bigger injectors with this SC? I have already 48lbs injectors.
    Thank you for your help, I think 15/22 is a good compromise but people say on different topics that it is too big for a PX260. They advice to use 14/19

    48 lbs injectors are barley big enough for the stock sc
    the new 300s have 60lb injectors
    300hp on a 1500 is about 15psi

    Thank you very much Chris,
    I will check the AFR and change the injector if there is an issue. For the moment I have the stock rpm limiter.
    Which injectors do you suggest? The 60lb injectors from the new 300?

    use the injectors your tune is mapped to use
    like vtech uses vt1100

    I have build it , but you can't using more 260HP .
    Because the tunnel of pump it's low size !
    And you must use ring nozzle 86 mm , never low
