Damon,
Your SC should be in the 13's if you drive it right. I have wwwaaayyy less done to mine and my quickest time is 14.4 @ 92 mph. SO, you should easily be in the 13's
All I did was put in 3.27's, K&N filter, Removed Air Silencer, and I took off the mufflers.
When I took'er to the track I dropped my tire pressure to 25 psi (still not low enough, still had wheel hop) and slipped the clutch off the line and held it balls to the wall after that. Fourth gear wasn't an option cause it would slow me down 2 to 3 tenths of a second so I just held'er out till the end. I hit about 5600-5700 rpm by the end in 3rd. But she held up so its all good.
But, good luck when you get out there.
Later,
Hock
