    Horse Power gains for each mod TABLE list

    Did someone make a list of horse power gains with each mod?...
    I know for sure X charger, 42 injectors and X Intercooler, X ECU makes 40HP (dif in between RXP /RXP-X)
    But did some take the time to make a list...
    For example:

    4" Air filter
    2 Rude
    3 Rude
    Riva ECU
    Blackmaginc Manifold
    Free Flow Exhaust

    Maybe someone already do it.., if so please post the thread to know..
    many thanks

    Any horse power gains would just be guesses pulled out of someone's head and most times they are extremely over exaggerated.

    Gains are best measured by your GPS and even those gains would vary greatly by other supporting modifications.

    We have a speed mods and database that can help you see how much faster the ski will be with particular mods

    thats well know!!!!..

    I ask this because each time i meet someone that have a standar PWC... he ask me HOW MUCH HP did you have in there?
    I think its the most common question...., they want to compare it with a car....

    according to mr racing ..grabbing from coments he has posted on different threads....all the mods i have... and it is most of them short of a turbo ad motec..yeld about 325 to 350 depnding on tuning...air temp ect..

    how much did i spend to get 100 hp over stock..

    i think for most of us the dream of 400 to 500 hp is well beyond our wallets..and the reliability factor we are comfortable with...

    i rode home after the hydrodrags thinking about building a turbo system...and going stupid .... then came to my sences..even though i could make the kit in my shop ..made many for mustangs and other race cars.....those skis are violent..to ride and cant be just ridden around every weekend..race fuel ect..no thanks...neat but dont want a race only ski....

    that is why i am tryin to get to a more efficiant hull and cut alot of weight to get the speed and more important acceleration...and keep some sembalance of reliability and recreational usability

    a Riva ECU 255 engine setup with 50 lb Injectors, Rude2 SC or B-kit, open waterbox , stock compression, has real 290-295 HP on the dyno at 8550 RPM
    With Rude3 boost maybe 310 HP.

    Without high compression, CAM, high RPMs it's not easy to see 340 HP and more on a SC setup
