    What Can I do with this 155 NA Setup

    I have a 2006 GTX 155. I have already done the intake, wear rings, and impeller. What else can I do? Like any exhaust or anything? TIA

    I never looked in a 155 motor compartment but I would think that the exhaust is somewhat similar allowing an exhaust mod

    What exactly do you want to do? More top speed or more accelleration? You need to tell us what you want to do with the ski... Ron

    I would think thru hull exhaust would do more for a NA ski than our SC skis. I have a friend with an 06 GTX 155 and we put riva thru hull on his ski. he said he didn't notice much difference in power though. We're doing a 3 inch kana flex intake this weekend though. I would think this would wake things up a bit. He's the only person i know with Race Engineering block offs on a NA GTX as well!

    Unsure but, doesn't opening the exhaust on the 155 motor hurt holeshot? Somethin about it needing the back pressure from the exhaust for peak torque? Pehaps a little more on top though? I believe that the loss of holeshot would be greater than the increase in top end. That is of course if what I'm saying is true?

    Sorry I couldn't be of help.

    You still have a fully baffled waterbox when you do thru hull. The only thing you would be doing away with is some longer plumbing and a resonator thats straight through anyway. Like i said the Riva thru hull works on an NA ski but my friend said it didn't make a noticable difference.
