Speed limiter on '04 2v?

40th GT · Oct 11, 2005

Just wondering if 99-04 GTs came with a speed limiter? I couldn't make it past 138, and I know some guys on here did 145-150 in theirs.

Also, what gear should I be in? My car was screaming at 6k in 4th gear and I was at 133-135, so I had to slide into 5th.

Oh yeah, this test was done on a dead road, where no one else can get hurt besides me.

Most ive ever done in my GT was 100, the 2000 GT I had up to 135-145 and it felt like it wanted to take off, damn 4x4 . But to answer your question, id say 140-145 is about it for a bone stock 5-speed GT.

i ve hit 145 in my GT when it was bone stock then let off but it was a one time thing just to get it out of my system

The speedos aren't calibrated for more than 100 mph.

I would see how high I can take my 00' GT, but I really dont want a ticket. Actually, that fast I think its straight to jail.

Have you done a gear swap to the rear by chance? With 3.27's, a '99-'04 Mustang will top out in 4th gear, but not in 5th. But....if you swap out to a set of shorter gears like 3.73 and higher (numerically) you'll run out of gear in 4th, but will still lack the power to pull it in 5th.

My old 5.0L was faster in 4th gear with the stock 2.73's in it than it was with the 3.55's. It would burry 1:1 4th gear ratio pretty easily, but still not make enough power to pull the .68:1 5th gear all the way out to redline.

138 is fast enough isn't it?(i coast at 135)

Um I have 3.73s and when i was making 248RWHP (about 20 more than stock) I had mine all the way to 148MPH in 5th gear (3.73s). If I had the stock size tires it would have read a good 150. Stock woulnt have any problem carrying over 5th with 3.73s for a good ways. When I had an O/R X and E waterpump and stock gears, the car would pull in 5th...but just BARELY.

And to the original poster...YOU CARRIED IT OUT TO 6K! In freggin 4th? Im sure it took forever just setting at 5800-6K for a long time....well I guess you know your engine is sound now lol. But hey, iv been to 6300-6400 in 4th with my gears and cams (127ish)...but it doesnt hang around if you know what I mean. SO im guilty too.

jasonh_86 · Oct 11, 2005

I've done about 150 in 5th gear at about 4250 rpm.. still had some pull to it making it go.. had to let off due to the fact i had to exit the interstate soon

I would like to get something that could tell me my exact speed and top it all the way out.. just for ****s and giggles

sgarlic · Oct 12, 2005

Damn.. you guys really go that fast? I've never been past 100 in the '04.. the '88 on the other hand..... woo-wee.

ocbaud · Oct 12, 2005

here's my speeds:

'01 stang gt : 130mph(so far)
'02 stang v6 : 118mph(limiter)
'86 chevy c10 : 134mph(no more gearing)

jmajorboner · Oct 12, 2005

I read somewhere that the computer shuts off gas at 149mph

baken78 · Oct 12, 2005

Had mine up to 150 after disconnecting the exhaust from the cat back. Seems these engines like less backpressure. I reconnected my exhaust with the aftermarket mufflers and I could only run up to about 136... No clue why.

By the way I'm new here so HI everyone!

goshia · Oct 12, 2005

Yes the Speedo is limited. Use a diablo sports predator and you can remove the limiter.

Whats the point of having the limiter removed?? If we had a autobahn then yeah but I would not want to get stopped by the Po Po for going 100+mph, just my .02.

StalkerStangGT · Oct 12, 2005

With ur stock 3.27's my 04 GT bounced off the revlimiter at 140 mph and fell on its face when u shifted to 5th

with my 3.73's i bounce revlimiter in 4th at 120....then when i shift to 5th it falls on face but it still pulls a lil.....i've had my car to 150 then i let off.....i have a predator but i havent adjusted the speed limiter.....if felt smooth to me.....didnt seem i was going that fast

Yeah, once you get caught for going 100+, you're off to jail.

I think I'll bypass the speed limiter and take her to the salt flats or something. I wanna see what it can do with a stock body/engine.
