can anyone give me a guesstimate on my 1/4 time... heres my mods
bbk cold air intake
cat back exhaust not sure on brand lol
4.10s
bfg drag radials
1999 gt coupe, stick and im weighin in around a beefy 140 lol

 

withthose mods i can say 13.5-15 sounds about right. its all in the driver,car conditions,track etc... there is alot of factors so basicly its easier to just say

"go run it and tell us how you did".

 

lol wen i do ill tell ya i was just seein if my thoughts were close and my guess was same as urs

 

I ran a 13.7 @ 100 mph with:

3.73 gears
CAI
70mm TB
SCT Xcalibrator tune for 91 octane
magnaflow cat back
Mac OR-X pipe
BFG DR's (255 series)

that was with a 1.9 60'

I'm guessing your about the same elevation as Iowa. It was about 65 degrees that day as well

 

I ran a 14.17 @ 97 with a 2.0?? 60' when i only had flowmaster catback and im in an auto.........definitely depends on driver and track conditions

 

Driving is DEFINATELY a factor. I've run a best of 14.3 in really hot weather and 14.4 is great weather with the mods in my sig. traction was a factor but I have to take most of the blame.
