On many Mustang forums I notice a lot of automatic owners wondering what they'll average in the 1/4 mile, basically stock. Welp, I finally got to run mine 3 weekends ago and figured I'd throw some input into the numbers I got.
It's a 1998 Mustang GT, non convertible. 75,000 miles. Has 17's on it with 245-45-17 tires (factory size).
Only modification is a X-pipe. Stock manifold, stock mufflers. Stock intake. Was also at stock height, whereas it isn't as of 2 weeks ago. (Hope to run it again lowered, not that it'll really matter).
Car is also at factory weight. Also have a 30lbs sub box in the trunk along with a 30lbs toolbox. 60lbs? Not an issue. 165lbs driver.
I know the type of tires might matter but they hooked right away. No spinning at all, so I doubt that's an issue either. Heated them up pretty decent before approaching the start line.
Now realize, this is a 98 GT. 96-97 had a 10hp decrease and a 5ft.lbs decrease.
It was about 55 degrees out and I had a half tank of gas.
I ended up running a 15.006 (.477 reaction). Made 4 passes and they were all VERY close. The slowest was a 15.024 (.524 reaction) This is much better then I expected because most of the forums I've read, they say mid to high 15's.
A big issue I'm noticing on this car (probably all 96-98 GT's NPI) is the fact that it runs out of breath before the shift point. So for about 400-500rpms, you can feel it lagging until it hits the next gear. Especially 2nd to 3rd. Right when I hit 3rd, I'm at the finish. Maybe once I gather up a PI intake and PI cams.. it may breathe a little better. Was thinking about purchasing a programmer for the "shift points" but I'm pretty sure that's the daily driving shift points. Not the redline, although I may be wrong. If I am, please let me know. I'd hate to get into serious tuning just to change my WOT shift point from 5800 or so to 5400 or so. Once 2nd switches to 3rd, there's a HUGE power gain once it's back into it's powerband. I'd be in high 14's if it wasn't for the high rpm lag between gears. :undecided:
