It can be added:
High-altitude = less air means less O2 and less HP ....to increase HP is to increase O2 .... Three ways come to mind....get a O2 bottle: 100% O2 and allow a small amount enter the air intake ...... more HP
second method: drag racing fuel adds a additive which is rich in O2 to increase HP... much more HP ......
Third method: replace the carb with a aircraft type which is designed for high altitude ....
Take your pick.....a non-turbo approach or go with a supercharger .......

Dude, that was a great explanation of the relationship between air and

Is there anything that can be done with a normally aspirated

adding a turbo?)

No.
To both. *smile*
Gasoline engines don't run right unless the fuel/air ratio is spot on.
High-altitude = less air. With a carburetor the quantity of fuel added
has to be adjusted to match the less-air situation.
Diesels don't work that way. The amount of fuel determine the amount of
power. Less fuel means less power - but always (aproximatly) the same
amount of air. Of course there is a limit to how much fuel can be added.
One there is enough fuel to burn _all_ of the air, more fuel is a waste
- and just makes smoke. This means that the only time there isn't extra
air is at foot-to-the-floor driving. (which is most of the time in my
240s...)
Anyway, if we drive up a mountain and so have less air, then the maximum
quantity of fuel is also less - and so the maximum power. To make sure
we don't waste fuel and smoke like the dickens on the mountain passes,
the fuel pump has an air pressure sensor, called an ADA.
The only way to fix this problem is to get more air into the engine.
The tool to do this is called a turbo. *grin*
Lee, if you _really_ like that car, putting one of the low-pressure,
aftermarket turbos could gain you what the altitude lost.
I think the better choice would be to get a factory turbo engine -
either in that car or another one.
Philip, drove to the top of Pikes Peak in a turbo 300.
Pretty gutless till the turbo spooled up!
