Turbos don't like high elevation because the air is thinner.
I understand that turbo charged cars don't like high elevations but I would think it would just get there a little slower correct me if I'm wrong here
This is completely the opposite guys. Turbo charged cars handle elevation better than NA cars. It's compressing the air to a set level. It may hurt spooling time and will effect it some, but not that bad.
From wikipedia " General Electric engineer Sanford Alexander Moss attached a turbo to a V12 Liberty aircraft engine. The engine was tested at Pikes Peak in Colorado at 14,000 ft (4,300 m) to demonstrate that it could eliminate the power loss usually experienced in internal combustion engines as a result of reduced air pressure and density at high altitude"
