Stock 2007 RXT, SC wheel change

[gbayus]

Assuming no other modifications to my stock RXT215, can anyone tell me what benefit if any would be realized by replacing the original SC wheel, which I think is a 4.5 boost with a 7.5 boost wheel?

Minor mods that I am considering while maintaining reliability:

- 7.5 SC wheel, steel washers, ceramic bearings
- Riva intake grate
- 2 degree wedge

Welcome to the forum... The more boost you have the more fun you will have. Benefits? Major power

Try cold air intake, prop 15/20 bent and gen2 wheel from Riva.

gbayus, is your RXT still under OEM warranty?

[gbayus]

Yes. For another year.

[R88ory RXP]

Yes. For another year.

You need to be carefull what mods you carry out as they may invalidate your warrenty.

If your going to change wheels get a Riva S3 bolt it in and go.
Best bang for the buck, ran a t that way all year last year, ran great and better fuel econemy as well.

If you are just dropping in a fan, as they say, you should do the Greenwheel. You will notice the difference in idle to WOT and part throttle to WOT acceleration. If you're not careful your arms will get longer

Mods to my 07 RXT are as follows,... Green wheel, steel washers, ceramic bearings and Riva toploader grate. Modded top speed results were approx 1 mph SLOWER over stock but acceleration was a huge difference! A 14/19 prop then got me 66.9 mph GPS at 2200 ft alt. in fresh water.@ 78oo rpms.

Cheers

you've got to upgrade fuel to go with the s3. The greenwheel/riva gen II/rotax are the only "bolt ons" (when you have to touch fuel components, i no longer consider it a bolt on)
