IS and AS Mod and Speed Thread
So I bought a 2012 RXT 260 IS and most of the speed stuff I have noticed was on the non ssupension hull. I wanted a post for guys with the suspension hulls so we can share what has worked and what has not. So far no mods on mine, but I did buy the Vtech tuner for future use. . Post your mods and speeds etc here? I am wondering about best grate to use what gains I can get from Air kit Vtech 8350 beta tune and a Prop.

I have a 2010 iS. Currently there is the Speed Limiter bypass module in there along with the 4" Air intake (no true cold air intake exists that I know of) and a Solas 15/22, which was set back and pitched back to 12.5/18.5 with an 83mm nozzle. I have 2 intake grates. The RD is the better overall and rough water grate. I have a Worx as well that makes a little more speed if the water has a slight ripple, but I use it for some rides because it seems to turn better. Right now, I'm a solid 72mph in the Florida heat, right on the Rev limit. Later on this year I will have retainers put on and do an ECU reflash (Torx or Vtech) and start running the 8350 tunes. I'm hoping that I really won't need further prop tuning after that, but we'll see. May need to add a tad more pitch.
PS: If you mod, DO NOT USE THE IS GRATE!!! I sustained permanent injuries from a 72mph pump stuff because of that grate!

72.5 mph with just 4 inch intake, 15/20 prop on a RS 2009 iS ski on fresh water in relatively cool climate.

I'm still running a 15/20 Solas prop....Stock Nozzle
I don't think I gained anything from the exhaust. It's not noisy at all on WOT....just sounds cool idling from the ramp.
My RPM's typically hold steady around 8250. Probably do for a repitch, but I'm gonna wait until after I upgrade my valve train and do an 8600 tune so I can do it all at once.

Do you guys know if the Prop I have from my 06 RXT will work on my 12 RXT 260 I have the speedfreeks setback and its brand new almost. Sure would be nice to be able to use it.
