Every kit we sell leaves the shop with a number attached to it. Not a claim, not a "gain" — a curve, pulled on a dyno, that you can read before you spend a dollar.
Four supercharger kits for the RZR Pro R. Same car, same dyno, four different afternoons. Pick a stage and watch what actually changes — not just the peak number everyone quotes, but where the power arrives.
Peak figures and pricing are live from the Packard catalog. Curve shape is modeled for this demo — swap in your real Dynojet CSV exports and these traces become your actual pulls, per kit, per fuel.
A naturally aspirated engine loses roughly 3% of its power for every thousand feet of elevation — thinner air, less oxygen, less burn. Your Pro R makes its rated number at sea level and nowhere you actually ride. A supercharger puts the air back.
Drag the elevation to see it.
Every product photo in the store is a part on a white background. Meanwhile the Instagram is full of cars at full throttle. These slots pull straight from the feed — the reel that sold the part sits next to the part.
"Ask the man
who runs one."
After the original Packard promise — Ask the Man Who Owns One. Warren, Ohio, 1899. The red hexagon rode on every hubcap; the Goddess of Speed led every hood. Different machines, same name, same rule: prove it.
