ok i'm at 4800 ft elevation, and running a 15.4 bone stock, well i was prior to intake and spec clutch, haven't been timed since, is this normal at this elevation??????

 

maybe it'd help if you told us what the car is

 

oops 01 gt 5spd

 

Well at 5600 up at PMI speedway in Pueblo, Colorado Mustangs are running mid to low 15's. . . but they its about a second slower than at sea level. . . My best time (with just full exhaust, bolt ons, no gears, no engine work, on BALD 245 Kuhmo ASX's) was 14.4. . . . So thats pretty slow . . .becuase i had a buddy clock a 14.9 in an 04 GT with just intake and exhaust. . . But he's been racing his whole life. . .So just work on your technique and get those down to 15 flats and then you'll be doing good. . .

 

ya the too killers for fast times is humidity and elavation... but 15's is good for that high up!

 

cool i just had my clutch replaced cuz the stock one was all jacked up, so i'm hoping that was part of the reason i couldn't come in lower than 15.4. the throw out bearing was SOOOO F#$%ed up. we'll see thanks guys.
