I was just wondering if anybody knew what to do to minimize the effects of thin air at high altitudes on our high strung motors??

I might make a trip out to Edmonton Alberta where the elevation is 2000ft higher than that of Vancouver's "local" dragstrip. The air in the neighboring province is also very dry compared to our coastal weather. If my childhood memories serve correct, August (when I plan to go) is also the hottest month!

So it will be HOT, the air will be thin and the air will be dry.... damn...sounds like a freaking desert....

any idea guys?

I don't want to find out my 14.338 time will come out to be a 15.0 flat time without a proper setup....!

 

Adjustable Fuel Pressure regulator.

 

more or less fuel then?

More since the air is thin to combat detonation?

or less since there ain't much air to burn to begin with??

 

I am not exactly sure, but I would go towards more fuel.

 

Air pressure will be less, thus 02 saturation will be less (in the combustion chamber). You will be running rich. No problems. BTW 02 concentration is relatively constant 18% unless you go up really high.

just think of a long column of air that goes up into the stratosphere....the higher the altitude of the base, the shorter the column, and the lower the air pressure.

Add a turbo, it's the only way to make up for some of the altitude loss. A psi of boost is a psi of boost at any altitude, but a turbo is the only one that will give full boost at any altitude. I give up 1psi for a mile of altitude.

You can advance your timing a little more up here, but I wouldn't recomend too much if you're doing a lapping day.

Other than that there's really not much you can do except just realize that it's affecting everyone else the same way.
