    '17 RXP-X 300 Stock Inter-cooler dedicated outlet

    Next item on the to-do list.



    Looking for any recommendations for the following upgrade...

    - 3/4" (19 mm) through Hull fitting for inter-cooler outlet? (as per graph) (Thanks for the info )

    - 1/2" (12.7 mm) through hull fitting for inter-cooler outlet?

    - Does the 3/4" (19 mm) keep enough back pressure for exhaust system?

    - Outlet control valve?


    Thanks for your help!

    Cheers

    You can go with 3/4” outlet.
    The first T-piece should have an internal restriction towards inlet hose IC.
    Towards exhaust manifold is full bore.

    Pull hose to check because ‘16 / ‘17 models are slightly different.

    is this where people were testing different sizes?

    12mm restriction?

    Groco Universal Water Filter/Strainer For Intercoolers

    Probably the most straight forward way to restrict intlet flow?

    Yes there’s a thread about that.
    I think it was the one you pull the temp. graph from.

    If you’re able to monitor AIT you can see the effect of every change you do.

    If you install a strainer you will have more restriction. But the goal is lower IAT not?

    It's a bit of a balancing act between IAT and exhaust temp.

    Just bite the bullet and get a fizzle, with the 3/4 dump my iats are constant 5degrees over ambient.

    Did you restrict the cooling water supply side to the fizzle or leave that stock?

    then 3/4 dedicated dump off the fizzle?


    I just want to add a dedicated dump line, but worried with starving the exhaust cooling been reading all the old forums but just not 100%. I have no logging capabilities so I cant really "test" out the restrictions sizes on the supply side

    Ive got everything I need for the dedicated dump on mine. Was hesitant but with the restrictor on the incoming T fitting, it should still have good water pressure going to the exhaust correct?

    You guys know the stock flush port runs in reverse from the dump right? If you dump the IC separately you better have a dedicated flush.
