Right around that speed is it's top speed, maybe 160 tops.

95

163.47 mph

395

About 70. At least that's what it should be depending on the speed limits where you live. But... as i'm sure those sign are just suggestions i'm sure you could get about 160

135

All cars are programmed with govenors that usually rate to the tires. If factory tires on the lil stang are rated to 150 then thats where the cutoff is on the throttle. Find out what speed your tires are rated and thats more then likely the top speed of the car unless you got it tuned.

a 2007 gt only does 150 but id say a 2003 does probably 170

You got this information from where?

i mean ive done 140 in my 07 GT and it was about at 4500 on the tach and it redlines at 6. I looked it up on like car and driver and they say an 07 GT does 149 tops. If Spencer said he was doing like 150 and the tach was at 4500 im sure he could get about 10-20 more mph. Ive been in a 2004 cobra doing 175. But in all seriousness its stupid to do these kinda speeds on regular radial tires. I regret doing 140 because it has shitty tires and probably coulda blown.

yea i have tires rated at 200 mph, but even then its pretty stupid to do and im pretty sure im not gunna do it again, but man if u get a blow-out at those speeds they would be scraping u up off the pavement with a shovel...

I've had mine on the dyno and it did 135mph on a 4th gear pull, 160 is a good estimate.

the top speed might be 160 then the cars computer will shut the fuel off

well i have an 06 v6 and she does around 195 and i run outta road

got a 05 gt tuned and the usual bolt ons(eliminated governor) and i can peg the speedo and then another 28mph according to my gps and thats all shes got, so 178mph. takes awhile to get there though.

you didnt do 195 in your piece v6 4.slow

if your computer is going to shut your fuel off it would do it at 112mph or 120mph mustangs are listed as 'governed vehicles' but really there not...

1,105

funny how the multiplier 1.6 makes it sound like ur a z06 eh... thats 121.875 mph...

1,105

178mph out of a 05GT man thats blazin fast... im skeptical man what 'bolt ons' are you talking about here... i gotta figure youd need 600+whp to hit that in the aero wall of a new stang...

1,105

kp/h mayb... but im with yah...

It's speed what kills.
