    Have you removed the flame arrestor from your intake manifold yet?

    Scooper, what speeds are you running with those mods and under what conditions?

    If your looking for good gains i would look at either increasing boost with 137 mm replacement, or get ecu reflashed to 8,400 rpm.

    they say you do not, but I can not speak from experience. that is for 8400. if you go 8600+ then I would think you do need valvetrain upgrade.

    PM brendus with regards to a reflash here in australia Aus dollar at 66cent against the Greenback and the 8400 reflash at $AU800+postage its a bargain I tried the reflash ECU on my RXT-X (which is stock apart from 15/22R and cut grate) definate gains to be had...but I was told I had to keep running my stock air intake....I think when you go to 8600 you need injecters but PM Brendus if you want to know more....

    Whats your current MPH, RPM and prop pitch??

    Need to max out what you have before moving on to something bigger that might just mask a hold up.

    2008 Rxt-X Mods Top Loader Intake Grate - Solas Concord Impeller - Pump Wedge - 83mm Reduction Nozzle - Custom 4inch air intake - Pro Series O.P.A.S Block offs - Dual Threw Hull Rear Exhaust - intake grate & ride plate holes filled - Boarding Ladder

    Pooper - I would like to see a picture of your "dual exhaust" inside and out - sounds interesting!! WHat are your current speeds, pitch on current prop, rpms, stock exhuast gutted? etc.

    More boost. I don't like adding rpm's until the boost is maxed out for the setup.
