The change in elevation does not have as big of an effect on the boosted power as it does a naturally aspirated motor. Never has changed the pulley out. You cannot ride that machine at sea level without full racegas but even a stock machine is on the cusp of detonation with anything less than 91 octane.

That’s pretty cool never seen a supercharged sled guys around here are all turbo then there is same power at all elevations turbine just spin faster to make up for thiner air u know boostpressure is controlled by Wastegate
