Default Higher elevation make this much difference?

Ok I'm not sure if anyone cares much but...Where I live (Southwest Virginia) everyone runs horrible times at the track which is in Bristol TN. This is obivious if you watch any NHRA drags here. The reason for this is also obvious. The air here pretty much sucks for short. Im beginning to think that the key to running well here is torque. Where a stock WRX, STI, or EVO will run around a second slower than they should (15.5's and 14.4's respectively) a stock SRT-4 will still run it's 13.9's to 14.1's. Recently I have raced, on the street mind you and from a dig, a 98 GSR, 05 SE-R Spec V and a RSX type-S. All were runs up to somewhere around 95 mph and all were stock as is my car for the exception of a homemade intake which adds from my estimate about 3 ponies. The thing is I have beaten all of these cars. The best victory was from the SE-R which was beaten by about 6 car lengths and both the RSX and GSR were lost by about 3. So what's up with this I'm not complaining but why am I running so well in this air?

Because the people you raced either cannot shift or were not trying. im sorry but there is no way a your beating a type-s by 3 cars. Take your car to the track, stop street racing, and lets see what the actually numbers are.

OK man till you come to this area and see what the air does to your car then don't post....I know how bad I beat the type-s and I also know that a friend of mine beat the same car even worse than I did with a second generation Integra with a b16a2 swap....rsx type-s's run 16.2's in Bristol and I have ran against a gsr that ran that and beat it! All I'm sayin is the air here or somin is messed up that's all!

On top of that why is it a stock Evo or STI gets killed at the track by stock SRT-4's? If it's so impossible for me to beat a type-s then why does this happen?

turbo cars have bigger issues with THIN air than NA cars

and some NA cars that run a HIGHER compression will have problems too

reason being for both is because turbo cars usually run around 10.5-11.1 compression and same with higher compression NA cars. with that compression they need more air to burn all the fuel the dump into there cylinders which makes all of there HP.

while in our car. our compression is low so we dont rely so much on a LOT of AIR and FUEL in order to produce power.

my logic might not make sense but

fact is that all cars perform worse with thinner air, and the higher performance cars feel more of a lost than cars of our class

Elevation of Port St. Lucie, FL: 24ft above sea level. (http://www.city-data.com/city/St.-Lucie-Florida.html)

Elevation of Saltville, VA: 1718ft above sea level. (http://www.city-data.com/city/Saltville-Virginia.html)

Elevation of Bristol, TN: 1672ft above sea level. (http://www.city-data.com/city/Bristol-Tennessee.html)

hahaitzskippy is quite correct, changes in elevation makes a huge difference in 1/4 mile times. As well as dyno numbers, which is why most people ask what elevation you were at when you were dynoed. The closer you are to sea level, the more dense the air is because of higher atmospheric pressure, and the more dense the air, the more power you make.

At higher elevation, both NA and turbocharged cars usually see a reduction on hp output. You will see more of a drop in hp in NA cars than turbocharged cars. rather than me explain stuff. here is a link...

As far as the evo and sti being beaten by a srt4 is completely feasible. There are a lot of variables. such as, driver error, street tires? slicks? turned up the boost? so on and so forth.

I couldnt explain it to you then, i dont know why but with the same mods, i ran a 15.4 in PSL and a 15.0 in KY. Multiple runs, and about the same temp outside.
