A naturally aspirated engine loses roughly 3% of its power for every thousand feet of elevation — thinner air, less oxygen, less burn. Here is what that means at Sand Mountain, machine by machine:
| Machine | Rated | At ~4,300 ft | Tax |
|---|---|---|---|
| Polaris RZR Pro R | 225 hp | ~196 hp | −13% |
| Can-Am Maverick R | 240 hp | ~209 hp | −13% |
| Can-Am Maverick X3 | 200 hp | ~174 hp | −13% |
| Polaris Xpedition | 114 hp | ~99 hp | −13% |
| Yamaha YXZ 1000R | 112 hp | ~98 hp | −13% |
Standard atmospheric derate, naturally aspirated. A supercharged machine holds manifold pressure as the air thins — boost pays the elevation tax for you.
Paddles for the mountain itself. The face is a horsepower dyno you can watch.
