    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
    Hi Fabrice, I think solas 14/19 is better for your setup.

    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
    You can make you pump tunel bigger, all most like rxp-x

    No kimi , I do not wish to change the tunnel

    my pump from rxpx 255 2008



    I can not determine a good pitch . I have an impeller Skat 15-19 ( with ring nozzle 86mm ), switch on startup , rpm max 8300 ( ECU 8600 )

    My GTI 260

    Hi Sylvain,
    Solas 14/19 impeller is recommended on improved GTR (stage 2 if I well remember)
    I think it is not a good choice to use a smaller impeller with a bigger SC.
    Thank you for your pics

    Hi, I can't make tunel pictere because this ski is sold. But I can told you whar you need to do. First you need to change pump shoe, moded your ride plate and change (to ss riva) and moded your intake grate. When you do that you can use solas 15/20r impeller.
    Cheers

    I use 2008 rxpx because this pump shoe 5cm longer and you will need drive shaft from old rxp or rxpx. Ride plate will be good yours, only make couple modifications with riva ss intake grates (2012 rxpx). Good luck dude.
