RXT Stage 1
Anyone have the Riva Stage 1 installed on the RXT? Just lookin for some personal reviews, feedback...

It's a good place to start but do not believe Their claims on speed. The 14/17r prop is what gives the most bang. Add a aftermarket s/c impeller and you'll have a true stage 1.

A true stage 1?
So Riva is posting misleading numbers then, hmm...
Anyone have the Stage 1 on an RXT who can post some accurate numbers?

i need to say that their claim for 68-69 is very accurate in my experience and several other RXTs i've ridden with that have the same stuff.
as a matter of fact, me and 2 riding buddies have RXTs that go over 68-69 with the stage 1 with NO intake grate.. all they are claiming is about 2-3 mph over stock, and that is easily attainable with an air intake, prop, OPAS removal, and pump wedge.

Thanks Shibby, what do you think with just the power filter kit...?
for two skis that would be about $500, hmmm...

I found just the power filter will add about 1 mph top speed when installed and some decent acceleration. Alot will depend on atmospheric conditions (heat, humidity, etc...).

The performance is directly related to water temp. and I live in the land of hot piss water called south florida. Shib, I would love for you to come down to Stuart and make that same claim. For me to run like you guys up north, I had to add the vortech s/c impeller and sometimes I don't still make it. Good luck and your enviroment means alot.

Well one mph is prolly not worth it to me then... maybe I'll hold out and do the stage 1 later instead... Jerry thanks for the tip tho...

I've seen one on Lake Ontario do about 74 but I don't know what was in it. Mark built it for a guy named Joe.
