    Hot air vs long intake system

    I just bought an r&d power filter for my 2011 GTS 130. It eliminates the air intake system/silencer. Since its close to the engine, isnt there a possibility of losing power since it might suck in hot air? Not sure how restrictive the stock long tube system and silencer is.

    BTW it claims 1-1.5mph and 100 rpms... believable?

    not much to worry about, temp isnt as much a problem on a non supercharged engine, airflow might not net you much gains, on that ski would look at handling mods , speed gains are hard to get.
    it is a non SC non IC ski correct???

    Yes, non-SC. I would be happy with 1.5mph gain with the intake and ride plate holes filled. Possible? (R&D claims 1-1.5 mph with just the intake lol)

    don't believe any gains with just a grate

    "temp isn't as much a problem on a non supercharged engine"
    I must respectfully disagree with Lextoy on this statement. Anytime you can lower the air intake temp on an internal combustion engine you will gain horsepower. It is true that a supercharger will increase air inlet temp after the air passed thru the supercharger because anytime you compress anything you will raise it's temp. I think this is what Lextoy was refering to.

    The gti 130 2011 is limited to 7300 rpm in the ecu.
    So if you are at the rpm there can be no more increase.

    But if you let Jerry upgrade your ecu he can change the rpm limiter to whatever you want.
    Maybe 8000 rpm
