🔥 2027 SEA-DOO RXT-X 350 | FUELTECH FIRST BOOST TEST | RUTHLESS TUNED 🔥

Today we completed our first on-water testing session with the 2027 Sea-Doo RXT-X 350 running FuelTech engine management!

💥 FIRST TEST RESULTS:

* Boost: 17–18 PSI
* Engine RPM: 8,600–8,700
* FuelTech Rev Limiter: 8,800 RPM
* Ignition Timing: Only +1° over OEM
* AFR: Maintained at OEM targets
* Fueling: Open-loop
* Impeller: Solas 14/19

We’re still running our Ruthless Racing Stage 1 hardware setup, with the addition of FuelTech engine management and open-loop fueling.

🏁 TOP SPEED READINGS:

* Factory Dash: 84 MPH
* FuelTech: 88 MPH

Unfortunately, our independent GPS ran out of battery, so these numbers are not yet GPS-verified. Tomorrow we’ll be back on the water to confirm the actual top speed.

Next up, we’ll be reinstalling the OEM impeller for back-to-back testing before moving to a 13/18 pitch to evaluate performance differences.

We’re taking this new 350 platform step by step, collecting real data and developing our own custom calibrations.
