The moment you cross the border into Colorado with a turbo or a supercharger, you car will cease to function.................. The manufacturer will state an octane rating for the elevation that the car is to be operated at. There will be a footnote about changes to be made if the elevation is increased. >My DJ would have a problem on Super Colorado! Since there are plenty of turbos and superchargers on the highway in Colorado, I would say the prevailing thought process of less octane at higher elevations is pretty much correct. If you are passing through the higher elevations with a turbo then the computer will compensate for it and you won't notice a lot of difference. If you live there, your computer/engine combo will probably be different than that of a person living at sea level. John |
