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

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.
