    310 and 300 externally vented bypass hose.

    OK, I am sure I read it on here somewhere.. About a kit that vents the supercharger bypass out of one of the vents near the rear seat?
    I hear lots of guys doing plenty of air mods, getting more air into the hull, vents etc.. But surely the best way to get rid of a heap of hot air from the intake is to get rid of that bypass going into the intake.. And not just venting it into the hull either?
    Would love to hear of any ideas or setups you guys are running. Thanks.

    The hot air from the SC is water cooled from the IC so don't know what you mean,any unused air thru the blow off valve is recirculated back into the air intake..

    It would be still hotter than ambient wouldn't it?

    It offers no performance gain just noise for the guys that think they are racing a wrx car. Remember it only bypasses when you arent creating any boost. Btw if your are one of those guys there is no kit just remove the hose from the intake and reroute it outside the hull via the rear tube.

    Haha, ok, definitely not one of those guys. if it does not have a positive effect on performance or efficiency, I don't waste my time doing it.
    It just seemed with all the focus on getting cooler air into the hull and motor, and with a filter kit being available to block off the hoses entering the airbox...it made sense, in my mind at least!?, to get as much warm air out of the hull as possible.
    I know it has no effect if running a big custom intake like your one that you posted, but if the motor is sucking air from in the engine compartment and hull.. cooler and denser air is always better.

    Cooler air in hotter air out,that's the formula for good running engine with a slight increase in rpms but better snappier throttle response and quicker acceleration will be really noticeable with these forced induction engines unless you have some underlying issues(boost leak,belt slip,dirty IC etc)..

    But the prevention of water intrusion comes first before any custom air mod of intake or exhaust air is made..

    The intake pictured is only for one event. Otherwise its sealed up for everyday riding. Removing the rear hoses seems to be the easiest way of removing hot air
