[QUOTE="ChiSVT, post: 11172508, member: 28706"] Supercharged cars lose just as much as N/A cars at altitude. If it were a turbo car that would be a different story. A supercharged engine can't process any more air and begins losing power as it rises above sea level just as a naturally aspirated engine does.. The difference in turbo cars is they often have more capacity with a wastegate to limit turbo boost, (which at altitude would just stay closed earlier and longer to compensate for loss in air quality). The type of FI needs to have the ability to increase speed or have reserve capacity to maintain sea-level horsepower at altitude. A positive displacement blower with x pulley doesn’t magically have the capability to process more air. It loses power as it rises above sea level just as a naturally aspirated engine does. The only type of supercharger that can compensate for a loss in air quality are ones fitted with a transmission. [/QUOTE]
