    Mods with out cooling mods

    All my stuff have had cooling mods. But curious if you start nodding these skis, will they over heat when ran hard? & alarm. & then cool back down & go again...
    then you know you need extra cooling?

    just curious if you have odd light mods vs over cooling & gas in oil. & odd climates

    Odd climates? Not sure whether I would qualify.

    Stage 1 Plus Riva SVHO GP1800 tunes. We operate mostly in moderately warm to quite cool waters (4C), air temps summertime hot to shoulder season mid-40F temps.

    Never encountered a warning or reduced engine power due to engine temperature while riding at speed. We rarely run wide open for long durations, perhaps a couple of minutes before returning to cruise range speeds.

    Primary cooling modification on our SVHO is enlarging the outlet in the plastic X that feeds the intercooler.

    I forget whether I also drilled the plastic tee larger that feeds forward from the exhaust pipe water feed.
    This is recommended by Riva for Stage 1 Plus tuned SVHO engines.

    So do you run riva or worx cooling in such cold waters?

    Just curious if someone has ran into the issue with some modes but no cooling mods & then did cooling mods. & if it warned them or if bad shit just happens.

    I do not understand this question.

    I have posted the changes related to engine cooling in my post.

    I do not alter the way the cooling system is configured between summertime and cool autumn/spring riding.

    Roger so you have drilled out the X fitting. So my question will be for others who have done mods but not cooling mods.

    So my question will be for others who have done [engine power boosting] mods but not cooling mods.
    The X fitting enlargement is to boost engine output by improving the boosted air charge density into the engine, the X fitting change does not improve engine cooling.

    Roger you drilled it out instead of running a dedicated line to intercooler.

    looking for responses from others who have done mods & not cooling.

    What kind of engine/power modifications are you including in your ‘mods’ definition?

    I am curious about all levels of mods with no cooling & weather they had temp alarms or not. Of later added cooling just to be safe or cause of alarms

    My stage 2 gp1800 I run a dedicated line to my fizzle IC, and dedicated line to motor. No overheat issues and run it hard sometimes in 78ish degree water and 95 degree air temps. Was running 86 mph yesterday full of fuel and gear, etc.
