    Any Opinions on R&D Intake?!?!?

    I like the look of the R&D powerfilter more so than the Riva, but being by the exhaust and at the rear of the motor, wouldn't it suck it mostly warm air...On the other hand..the temp of the entire engine compartment (hull) probably is just as warm up front...

    it does suck warmer air, but in my opinion the volume of air inside the hull is removed several times a minute by the air intake. so not that much warmer.
    however other kits offer larger diameter intakes aka, RIVA rear air, or a home made 4 " intake, that will allow cooler air(RIVA) or more air (4") to flow in, thus more power.
    look around this site, theres tons of info on intakes.
    if it were me i would make a 4" kanaflex front air intake, alot cheaper, and cooler air, more flow, best water protection.

    the air is also cooler up under the handlebars than back by the exhaust, so a front air intake is sucking cooler air, but longer intake tract. a 4" diameter intake tract solves the length issue.

    You can gain more with Riva filter...one thing that you can do is cut the Riva tube like a "L", then you can locate the Riva filter in the rear, near of the intake rear air seat.

    This is that we do in our race boats and we get best results that with R&D filter.

    I forget it.... other thing is install a (for example) fan assy from a sportboat (challenger 1800), in the RXT you can install in the ventilation tubo down the rear seat and drill the support seat to get more air flow, in the RXP you can install in the tube in front of the seat or maybe you can build a support down the rear seat. With this you force to intake fresh air....

    This not legal for stock races.

    Iside the hull i test the temperature around 65ºc after 15 minutes, with this you can reduce this temperature around 20ºc

    4 of the top 5 finisher's at the last LB2CAT were running the 4" up front kanaflex.
