And I think 140 ish might be achievable if you can improve the car's drag a little. Assuming you can get to 100 mph by the first 1/4 marker you are now travelling 146 ft/sec and will have less than 9 seconds to hit 120 mph by the 1/2 mile marker. You are now travelling at 176 ft/sec and in 5th gear and will have 14 seconds to accelerate from 120 to 140 (assuming hitting 190 ft/sec [130 mph] before the last 1/4 marker).
A base might have a slightly better run than a sport with no spoiler, smaller wheels and open diff. The gearing of the auto might also be more favorable.
So - borrow and auto base model and give it a shot
