Sea Doo RXT-X looking for more power - riva stage 2 not impressed yet

[Daniel475]

2022 Sea Doo RXT-X running JP racing Intake , Riva racing stage 2 AGR tune , riva racing water box with blow off valve , solas 13/18 impeller , online from what ive seen should be getting Low 80's 82 ish , so far im hitting 80 cant seem to get anymore out of it yet , any suggestions? thinking about going to JP Racing stage 2 , i was really expecting more since doing the impeller swap and the riva racing water box but so far nothing , thanks guys ! looking for a consistent 83-84 would be nice if thats possible

Where are you? How cold is the water? How much do you weigh? How much gas is in it when you test it?

[r1goombah]

what rpm are you at?

[Daniel475]

Vancouver BC Ice cold ocean water ! 165lbs and about 8400 on the dash , same with full fuel aswell as barley any in it made no difference

The waterbox won't add any performance. If you're not happy with the power then this would be the next step up:

VT1100 fuel injectors: https://www.4-tecperformance.com/ind...oducts_id=2156

Intake manifold upgrade: https://www.4-tecperformance.com/ind...oducts_id=4384

Fizzle Z135: https://www.4-tecperformance.com/ind...ducts_id=12846

Supertech valve spring & titanium retainer upgrade: https://www.4-tecperformance.com/ind...oducts_id=1979

Only way another tune gives you more top speed is if it runs more timing or leaner.

JP Racing Stage 2 won't be just a different tune. His "Stage 2" is the equivalent to RIVA Stage 3+.

Are you using a handheld gps to gauge your speed? Your stock dash is calibrated to read 2+ mph faster than actual GPS speed. Some tuners will only post dash speeds... and they run with the seat off to get an impressive number to mislead people and make them think their tune is better than the others... so just be aware of that when you are comparing claimed speed numbers.

Im on a Riva stage 2 also. Riva states that a 15/25R Solas will get you 2@3 mph or 83/84mph. You would have to change your wear ring to a 159mm one. Im in the process of either pitching my stock impeller or trying the 15/25.

[ptscon]

I would try the '21+ RXP impeller instead of that 15/25, you'll get more cavitation off the line with that impeller due to the smaller size.

hey greenhulk this is Dash speed im talking about not gps, ive heard the intake manifold upgrade is not good if your running in the ocean , correct me if im wrong, also is there valve spring install guide out there? im sure i can do this myself im fairly decent on the wrench , thanks for the info boys!

[guybb3]

I forgot to ask one of the simplest questions (and one I ran into), are you up against the rev limiter on the new tune?

Mine is a 2022 gtx 300

He mentioned 8400rpms. The stage 2 target is 8300rpms

I don't know where you heard that nonsense? Probably from all the novices on Facebook... LOL, but that info is ridiculous.
I highly recommend the intake manifold upgrade, and do the intake manifold girdle at the same time. These are the two parts you need
