Does anyone know, more or less, what 1/4 times and trap speeds I can expect to achieve in a bone stock G37S 7AT in Phoenix, Arizona? If you have summer times and winter times that would be great too. Thanks!

 

Here are some threads to give you an idea

I ran 13.7 stock

 

Thanks Vizard. I was hoping to find AZ specific times due to the higher elevation. I think Firebird International (PHX, AZ) is around 2000 feet elevation, so I expect the Gs to run a bit slower than people who are at, or close to, sea level.

 

I thought firebird closed last year?!

 

I thought that was only an issue with carburetors...

 

Higher elevations means the air is less dense. Cars, humans and anything relying on Oxygen get affected the higher up you go.

Carburetors just require retuning when ambient conditions change. Fuel injected cars have a ton of sensors to measure and make adjustments to ambient changes. Both setups when tuned will make around the same power when compared to each other regardless of elevation and other ambient conditions.

[EDITED POST TO CLARIFY]

 

Sounds like you used two paragraphs to agree with me...

 

LOL

I was just trying to explain how elevation would make both cars slower.

 

The second half of your statement is not really correct, as you can not replace the oxygen molecules that are absent from the intake charge by tuning, unless you were to increase the displacement of your engine.
Supercharged or turbocharged engines are less sensitive to elevation changes, but as a loose rule of thumb you will loose appox 10HP for every 1000ft of elevation on a naturally aspirated engine, that is at equal ambient air temperatures and similar humidity levels.
Here is a formula to give you an idea.
HP Loss = (elevation x 0.03 x hp @ sea level)/1000
I would say that if you are running at Phoenix in 95 deg ambient air with a naturally aspirated engine, you are going to be several tenths slower than running at sea level in 75 deg air.

I edited my post to clarify. I never meant to say an injected car will make the same power at sea level and at 5000 ft. I meant Fuel Injected and Carb'd setups will make more or less the same power when fine tuned all else equal.

 

My bad, I misunderstood what you had written.

Cheers,

Paul
