My '03 GT automatic dyno'd at 210rwhp and 265rwtq. It ran the 1/4 in 14.62-14.69sec/94.3-94.9mph w/2.18-2.25s 60' very consistent four passes in a row. Its factory stock including air silencer, motorcraft paper element, tires, the works. It weighs 3320lbs with a 1/4 tank of fuel. I've only ever run 87 octane in it. What are the proven upgrades that will give me the honest increase at the wheels to run mid to high 13s at about 100-101mph w/o lightening the car. I'm certain 4.10s and ET Streets will get me 3-4 tenths. We have a good track at just about sea level with great air. If you have a 2V auto and have dyno #'s or time slips to advise on what works and what doesn't I'd appreciate your input. I'm hoping to stay away from nitrous this time since I just want an everyday useable torque curve. An expensive supercharger is out of the question for me.
