Whoa, I guess the altitude really makes a difference eh. What state is that? Once you get the 60' down to a 2.0 you'll get a better time lol

Colorado. I was launching pretty softly. I could have launched harder. I was happy that i improved every run. i was hopping to get down to 15.00
My 6th run confuses me because i had a better 1/8 mile but then the last half of the race i was slower. I had let the car cool down for over an hour before my last run.

Panther its not as bad as you make it seem they have correction factors for that. heres a link for you it comes out being like a 14.2 or better cause the max elevation they had on here is 5500ft. http://www.gnttype.org/techarea/misc/altitude.html

Generaly we assume about a 1 second off of you run if you N/A. Little less if your boosted. Boost owns all at altitude in my opion. I really think i can get down to 15 flat when i go back. Maybe ill have a throttle body spacer by then. I wanna hit 14.7 N/A up here that my goal.
Also thinking about some shorter tires to help out the gearing

I say get your launch down and get those 60' times down to about 2 flat, your top end is no good though. I'd do intake (if you haven't) downpipe, TUNE, rockers

I wouldnt worry too much about those times, that is probably a high 13 run at sea level. As long as everyone is running similar times and you are competitive with similar cars thats what counts.

Dont feel bad, I live in El Paso, TX. 3900ft above sea level. I can't do much faster than 15.4. When I move back to NY I'll run it there and see what the difference is.
