Here is the story.........My friend has a 2002 Pontiac GTP (3.8L V6 Supercharged). It has full exhaust, cold air, and a smaller blower pully and upgrade pcm. He runs a 14.10 in the 1/4 mile. He raced a 2000 Mustang GT with a 5 speed. The guy in the mustang claimed it was all stock....and he beat my friends GTP by 2 cars. I am pretty sure that a stock Mustang GT will not run a high 13 at 2800 feet above sea level.

That doesn't sound right to you guys does it? A Stock Mustang running a high 13 at 2800 feet about sea level on street tires? Or does that sound like a hustle session to me?
My personal opinion is that he got hustled......


I personally am thinking gears and nitrous?

So many factors play into why the GT could have won.

IF the race was from a roll, the 5 speed has a huge advantage. The GTP will suffer from the altitude just like the GT, so you can just ignore the elevation deal.

I'm not sure what that GTP should/could run, so I can't comment much further than that.

Dan it was from a dig, and the altitude correction doesn't affect a force inducted car as it would a N/A car. Thanks for your input.

I'd be interested on understanding how altitude doesn't affect a FI car. Have a quick explanation or any information I can look at?

Your buddy most likely got hustled pretty bad.

I posted a story in Street/Strip a couple months back about a LT1 with a couple mods & he hung on fairly well until we got out of 2nd gear and I would just pull away. I saw the car in the paper, claimed 400hp. Gave'em a call on my cell and sure enough he mentioned the ol 100 shot of nitrous/

i dont think that altitude will really do ne thing to a fuel injected car, the higher the altitude the less dense the air is, but ur cars computer well notice that and adjust how much fuel is being used, and even if does affect a FI car, it would affect a s/c the same as a n/a car, think about it...

Supercharger

Air compressor or blower used in piston-type internal-combustion engines to increase the amount of air drawn into the cylinders by the movement of the pistons during each intake stroke. With the additional air, more fuel is burned, and the engine's power is increased. In aircraft engines, supercharging compensates for the reduced atmospheric pressure at high altitudes. Development of the gas turbine, which requires a constant flow of air and fuel, led to the turbosupercharger, a centrifugal blower driven by a small gas turbine powered by the exhaust gases from the engine cylinders.


Altitude effects

A supercharger remedies this problem by compressing the air back to sea-level pressures, or even much higher.

Regardless of the situation.....a force inducted car does not suffer the same affects that a N/A car will. As soon as you come under boost guess what.......^

You are a moderator so I am not trying to undermind you. I think my buddy got hustled...but in my mind I am like it is a good kill for a "stock" mustang.

I know you weren't trying to at all. I just wanted to read more out of interest. Good information!!

I think that would have to be a perfect run for the GT to run 13.7ish at that altitude. Now i have seen several run that stock but it was at sea level with good air etc. Those GTP's with smaller blower pulleys and mods can get into the 12's....So if your friend ran a 14.0 and he can drive/get good traction then the GT should have did more like a 14.5 if iy was stock. Probably had 4.10's and a small cheater NO2 kit. They can be hidden and only pack enough punch to drop a few tenths.

my stock 01 GT beat a 98 GTP by about 2 1/2 cars. he had smaller pulleys and an exhaust...ur friend prolly had an exhaust or something done under the hood

ya no stock GTs running high13 or low 14s here and where at 2856 the best stock 99+ gt i have seen run was 14.4, so someone is pulling someones leg
