I used this tool to crunch the numbers, since I didnt feel like doing it myself. One drawback to this page is that it gives static revolutions per mile based on tire size alone regardless of what the tire maker says it should be, but for an estimation it's close enough:
Assuming no speed limiter, 6850 rpm redline and in sixth gear.
2.73 gears in a base v6 you get 295mph
2.73 gears in a mca v6 gives 291mph
3.31 gears base is 242mph
3.31 mca is 239mph
perf pac only comes one way (3.31 and 19" wheels standard) and comes out 237mph
These of course are impossible figures since we aren't taking into consideration air drag. as a matter of fact, the only cars that hit these kind of speeds are hypercars like the 1000hp Bugatti Veyron and even then it has to be put in a special "high speed" mode where it closes all the spoilers and drops its suspension to the ground. So, lets run the numbers again in 5th gear which is a 1 to 1 ratio:
2.73 gears in a base is 206mph
2.73 gears in a mca is 203mph
3.31 gears base is 170mph
3.31 mca is 167mph
perf pac is 166mph
Now, these are closer to real life I suppose and if theoretical is all you're after then they're good enough.
With a blower, maybe the Perf Pac car could pull redline in fifth. I really don't know.
so funster you keep crunchin them numbers while stackin that corn, I'll keep vacuum packin it, here's your new avatar ........this was some good sweet corn,,,, now back on topic, if I can go 130 happy...

I had an 00 Lincoln LS V6 that I was able to hit the limiter at 133, and that car weighed about three hundred pounds more and had 95 less horses. I would bet with this car, and the power to weight ratio it has can do 150+. I know that the V8 LS's had 252hp and top speed with them is 149-150 due to air resistance, no limiter.
I installed my tune yesterday and wanted to make sure the limiter was removed. On the way home from work this morning I hit 132mph before I backed off. Started to get a little light in the front end and a little shaking but could have easily hit 140mph or so.
Does anyone know what the Top End Speed the V6 can do? What gears in rear? This is with limiter removed.
For me at a dyno 4th gear 160mph 2.73 ford put a limiter in the engine some how because 5th and 6th just lowered the rpm. Thank God my drive shaft didn't snap. But this car has more to give than 160 mph.
Ive gone 150 before and was running out of road and backed off. Found out right then the brakes aren't worth a crap! Since then Ive replaced them with Hawk pads. Car sure seemed as if it was still pulling too.
I just got on this forum a few days ago and noticed a few have had driveshaft problems. Is it a certain year or transmission (auto or manual) that are having problems? Feel like Ive pushed my luck but always have in my 50 years!
