I Live 1600m above sea level and when my dad and me went on a 4000km road trip along the coast of South Africa the car felt like it had much more power. Its a 2.5 v6 automatic and coast side it would spin the wheels when you would accelerate hard from a standstill, something it doesnt do where I live.
Now that I'm back home I miss the extra power I had at the coast, tried googling it, anyone knows the % you gain when going to 0m sea level? Or perhaps how to duplicate the power gain in land?
Thought I share a picture I took at Knysna, its between Cape Town and Port Elizabeth
