    need advise about intake grates.

    Hi all,

    I have a modified RXP 2004 with R&D grates. When I was in stock my max was 105km/h .

    and now with 15/20 prop, X supercharger, XS intercooler, I'm only going at 112 km/h normally a stock rxp or rxt goes at 116km/h.

    It seems that the R&D grate really act like a handbreak on the jetski cause when i go full speed, if I stop accelerating the jet will just slowdown really really fast .

    So one issue is the R&D really slowing down the jetski? and what over grate will be good for offshore issue without loosing alot of RPM?

    I would say its your prop more than the R&D top loader.

    LOL, I was thinking the same thing. Convert to MPH and you'll probably get more responses.
