I've had my 2001 GT with an auto up to around 140 with just K&N air filter. I know what some of you guys mean by the speedo being high and you cant come anywhere close to it. My old cars speedo said 140, but was governed at 109, which sucked.

I still have stock gears and I have hit 138-140 in fourth. 155 is the fastest I have had it and that scared crap out me . If the had been lowered with a nice sleek kit it might have felt more stable.

145 in 4th? hell no. Not on a GT anyways....Cause i think my 4th tops at like 140....but then again, i have never redlined 4th....i have only been that fast a few times, and i shifted into 5th way before redline...and i have had my car past 150...

Not sure of the exact speed cause my speedo stops at 150, but the needle was past the 150 mark...

Because you have 3.55 gears and Gt's have 3.27...

First off, where the "governor" kicks in is directly related to the speed rating of your tire. Our cars have "Z" rated tires, which I believe are good for over 150mph, so therefore no speed governor, they just run out of steam. I haven't run up my '04, but I did run up the Bullitt to 140, and it was still pulling nicely in 5th.

ok this is pretty much y i joined i don't know alot about mustangs yet but i got talking about mustangs with this guy i met the other day and he was telling me his stock 99 GT would do 145 mph in 4th gear now i'm no einstein but i call bs on this one. so i want you guys to give me some feedback. is that even possible.
Here you go....Look at the speed between gears....This one hit 135....So it's very much possible. I went i think 140-145 coming down I-90 racing an SRT-4...The old school fox bodies were known for running as high as 148 in 4th gear.......but they had 3.08 rear People will argue the facts because they haven't done it....But i know i've done it....5th gear is overdrive....Top speed is achieved in 4th in most cases...........

Year, Model, Mods and how fast have u been?
2001, GT, ALOT of bolt ons and pegged the speedo. The fastest registered on radar was 152.
Yeah but you got gears Code. Gears would make you top out alot sooner than you would in stock trim....

I brought mine right up to 138 @ 5700 rpms in 4th so im sure i could have brought it up a bit more to at least 140, but 145 is pushing the redline, not something i would ever do...
