I think a normally aspirated engine will go slower at Bonneville than 'back East'.

The elevation of the flats is 4,200 feet.

Compared to sea level the oxygen density, and power making ability based on volumetric efficency is around 85% of sea level.

A turbocharged or supercharged vehicle will go faster due to the ability to overcome the thinner air via compression while still reaping the benefits of lower wind resistance.

All true, but I think you could compensate for elevation and density changes with careful jet selection.

You can minimize loss by maintaining a stoichiometric mixture, but with less oxygen and less fuel there will also be less power without forced induction.
