altitude and nitrous
 

How does high altitude affect nitrous tuning? can you put more nitrous to an engine to try and compensate for the loss of power due to lack of oxygen?

altitude shouldn't affect nitrous use. altitude affects all motor, but you shouldn't up your jets because you're at a higher altitude. if you are going to increase, do it incrementally.

you're not far from me, isn't Portland just above sea level?

If you are basing the amount of nitrous/fuel you can add to the engine before it explodes from the strain of the extra torque; simple answer.. yes.. but only a bit and you would need to know how much power you are actually putting out and know what that engine will take before going boom.



Are you looking to add 50hp or make a certain goal? If you after a specific output you will have to increase the shot because the "base" horsepower is lower. Or more like there is less air to work with so you have to add less fuel.



Lets say you are making 80fwhp without spray because of your altitude is robbing 20hp. Put the correct jets to really add 50hp at the flywheel. (some hyundais run pretty high fuel pressure so check that) and you get; 130fwhp at peak.



Same car at sea level with 100fwhp will see 150fwhp.



However, both see the 50 increase because the bottle pressure is going to dictate how much gas is flowing and how much extra fuel you can burn; not the mountain you are living on. I am sure its not that direct because some of the power, from what I understand, comes from chilling the air when its released so there is less natural air flow to be chilled.. so it would depend on how much that effected things.





Want to get 180; need to add more oxygen with a larger shot and the fuel behind it relative to sitting at sea level.
