    2010 rxt-x air intake debate

    I still cant make my damn mind up what air intake to go with and have a few proven options. But what is best, safest (water injestion proof), best value etc etc

    1) Fizzle 4" Front air intake +Catch can required

    2) Les Cooke Kanaflex Rear Air with K&N 4". Breather hose recirculated back into air intake.

    3) Riva 4" Kit with Bulkhead heat shield +Catch can required
    http://www.4-tecperformance.com/inde...oducts_id=1608

    4) Speedfreaks Rear Air with intake tray. Requires ic relocation

    Thoughts, comments and any actual test results would be very welcome.

    IMO #1 is the best & cheapest option with both stock air tubes re-routed right next to kana intake filter.

    #2 Rear air setup brings in TOO much hot air.

    # 3 same as #1 in performance - big cost diff - you can make make your own heat shield for about $12.

    #4 is a SUPERIOR product BUT, not for X 260 seat, it is for 2009 and earlier 2 piece seats for RXT/GTX setup.

    I got no more speed with 4 inch fizzle as the RPM limits it to 8040 anyway, MY midrange is better with stock air intake, tried it off and on twice.

    I am leaning toward the Fizzle type set-up at this stage. It would be great to do some back to back tests on top speed/rpm/heat soak over time etc. Spoke to Les and he has tested every which set-up and swears that his way is the only way and not to use a catch can with just the 3/4 fitting for the breather hose to re-circulate back into intake.

    My take is that a rear air set-up is more likely to suck in water that tends to come in under the seat of the tx and agree with JT that it sucks in toooo much hot air. Dont know why Seadoo centre insist on this way.

    With my Speedfreeks repitched prop I am spinning 7990rpm so the intake should help top speed. Prop and intake seems to be the secret recipe on budget.

    Clearly nice cool fresh air helps these ski's perform their best. The biggest performance game changer is the weather - high barometric pressure over 30.00", low humidity, low dew point, lower air temps, low relative air density altitude = optimum horsepower. ALL of these parameters have a huge impact day to day, I've seen 100-200 rpm changes with big weather changes and speed changes of 2-3 mph. It's all normal ops but has to be accounted for in comparison of different mods.

    I had that short set up and I really liked it as it was a clean install. I tested the short set up against the Kanaflex & heat barrier and found routing the Kanaflex up front combined with the heat barrier produced better top end speed.

    That is the ultimate set-up imo. Is this the riva one or did you make it up yourself?
    Chances of water injestion with filter mounted up high above fuel tank is very low.
