    3" Intake Holding Me Back

    Went out today and ran 80.0 solid then pulled off the filter and gained 1.1 mph from just removing the filter! I'll be putting on the 4" asap. Just proof that the 3" holds you back on the bigger boost SC's.

    Yep.
    I run without filtration on both skis.
    4 Inch all the way either direction , front or rear is the way to go.

    Not running a filter is really not an issue for me as I don't ride in dust storm and when skis are in transit or stowed the intakes are covered up.

    Put a pod filter on a flow bench, not many of them flow any good at all.

    That's true. I was just surprised the filter alone was holding it back that much.

    Did you have the outer wears on? Every RIVA 3" filter I have seen was partially crushed I am guessing from suction from the SCer.

    No it was just the bare filter. And yeah, my filter is a little crushed.

    Yea, couple years ago I was out riding with a guy with the 3" RIVA with the outwears. I asked him if he wanted me to make it .5mph faster in 5 seconds. I pulled the outwears off and thats all it needed.
