My car -> 05 Mustang GT, manual, 3.55 gears, Bamachips 93 Race tune, C&L Street CAI.
Other car -> A beautiful white 05-09 Mustang GT with great looking aftermarket mags and wide tires, sequential taillights, lowered, tranny-?, gears-?, mods-?

He pulled along side me on the NE extension of the PA Turnpike this afternoon, both doing 70 mph with no other vehicles in sight. I D/S into 3rd, nodded once, and we were off. I immediately started pulling on him, was a car ahead by the top of 3rd, and continued pulling in 4th. He gave up, and dropped back quickly. I slowed down to 50, and waited for him to catch up so I could give him a , and ask him about his ride. Unfortunately, I never got the chance as he quickly scooted past me, and eventually got mixed in with traffic.
I'm guessing he had no performance mods, and his car was a later model GT with 3.31 gears based on how easily I was able to pull on him.

good kill!!but 3.31s are actually better for highway,im sure he was stock!!

Thanks for the kudos.
Yeah, his car certainly acted like it was bone stock(excluding the bling factor). Unless it has performance mods and a manual tranny, and he punched it in 5th gear.

However, I gotta respectfully disagree with your assertion that 3.31's are always better than 3.55's for highway races.
For instance, let's dissect my race today, which started at 70 mph.
That put my engine's rpm at its max torque rating(4300 rpm) in 3rd gear with my 3.55 gears and 17" stock Pirelli's. If we assume his car had 3.31 gears, manual tranny, and his tires were the same diameter as mine, then his engine would have been slightly below max torque(approx. 4000 rpm). Thus, my engine's slightly higher torque output alone would have given my car slightly greater acceleration at the start of the race.
But of far greater importance, my 3.55's would have accelerated my car much faster throughout the entire race(topped out at 110 mph) by enabling my engine to rev to redline quicker than his engine due to the higher MA(mechanical advantage) of my 3.55's.
Of course, the above also assumes that other less critical factors which affect a car's acceleration, such as air and tire rolling resistance, were identical. However, lowering his car may have reduced his car's air drag, while his wider tires definitely increased it.
On the other hand, things may have ended differently if the above assumptions were true, and the race had continued past 130 mph.

good point,the 331s are actually good past speeds of 110.i should switch gears

Sounds like he was stock. nice kill though.
