Which prop? 05 RXT
Here are my mods that are going on this winter:
-Rebuilt SC with either GW or Riva II (are they the exact same or do some perfer one over the other)?
-4" custom into filter mountd in front. With catch can.
-Riva exhaust, just the pipe not the through hull kit.
-Riva intake grate.
-Riva pump wedge.
-OPAS block off kit.
Basically a stage two minus the intercoller, blow off valve, sponsons, and the cheaper exhaust kit. Riva recomends the Solas 14/17r for the Stage 1 and the 13/19r for the Stage 2. Which prop should I go with? Any help is appreciated.

I would recomend looking at this thread, http://greenhulk.net/forums/showthread.php?t=16773 but I think the 14/17 should still be ok for you. Once you go to stage 3 wheel, IC, and 42# injectors you will need the 13/19.

Hi Neal, the GW and Riva Gen II are identical.
For the setup you have planned i would actually go with the 14/19R.
I know many guys that have used this impeller on their RXT with great results.

Here is my personal experience. Hope this may help you out. When I was at a stage 1+ I ran the 14/17 at 8000 RPM. So I could have used more mods with that prop.
With these mods on my 06 RXT Stock ECU, 4" intake, XS intercooler, Riva stage III SC, 42lb injectors, GH Waterbox, 2* pump wedge, VTS, Riva intake grate, Riva nozzle w/83mm ring, Riva catch can, 160* thermostat mod, Riva OPAS block off, Riva sponsons. I ran the 13/19 and was right on at 8120 RPM and 73.6MPH in the summer.
Now that it is winter and I added an intercooler bleed mod, plus I have added couple more things, I am running a 14/20.75 at 8100 RPM with 80mm ring at 74.8MPH.
