Altitude... anyone at one like mine? I live 5000 feet above sea level... and the DA averages up to 7000 on a high 70 degree day... my poor LT1 ran a 14.97 stock...
I doubt 6psi and traction is going to make my car run 12s (i doubt even 8 with do)... what do you guys think?
How many of you face the same problem as me?

Our track is just over a mile high, 5320ft. DA during the summer gets as high as 8-9000ft. 
My car ran a 14.3 stock
I'd be in the 12's club if I were at sea level.
You said 6-8psi? Are you talking about FI? FI doesn't lose as much to the elevation as n/a cars. At that elevation, about a full second for an n/a car and around half a second loss for an s/c or turbo car.

I was hoping 6 psi would get me in the low 13 area... but im sure that is hi hopes... i want lower 11's with 3 speed, stall, t-brake, 2-step, and turbo.... i have everything but the t-braked and stalled 3-speed.... so we will see

i dont get it? what effects does altitude have on a 1/4 mile time. i live in alabama and im not much higher than sea level but ive just never understood what makes you slower. air density or something?
