When a Sea-Doo or WaveRunner owner wants real speed, the catalog is RIVA — and the difference between fast and broken is the shop that installs it honestly.
PWC performance has a physics problem: every mile per hour past stock costs more cooling, more fuel, and more pump than the last one. RIVA's catalog — intakes, exhausts, impellers, ride plates, ECU tunes — is the proven answer, and the failure stories all share the same plot: parts installed as trinkets instead of as a system.
Our installs do the system math: intake and exhaust paired with the tune that expects them, impeller pitch matched to the new power curve, cooling upgrades specced before Texas summer exposes the gap, and the supercharger's interval status verified before it's asked for more boost. Then the test tank and a GPS run prove the number instead of promising it.
Platforms: Sea-Doo's 300-class machines are the volume kings of RIVA work; WaveRunner GP/FX SVHO builds run a close second. Both leave here faster and still reliable — in that order of priority, honestly stated.
Stage-dependent and honest: a Stage 1 package (intake, exhaust, tune) typically buys meaningful top-speed and acceleration gains on a 300-class machine; deeper stages climb from there with matching supporting mods. We quote real numbers for your hull and verify them with GPS — not brochure optimism.
Built as a system with cooling and fuel respected — modestly and predictably; the machine works harder, so intervals tighten. Built as a parts pile — yes, quickly, usually in August. The difference is entirely in the install philosophy, which is why ours starts with the supporting-mods conversation.
Almost always — performance calibrations expect 91–93 octane and Texas water temps make detonation margins real. It's written into your documentation at delivery. Running regular through a tuned supercharged machine is the fastest way to fund our engine rebuild bay.
Tell us the hull, the stage you're dreaming of, and how you ride. We'll build the system version and prove the number in the tank.
