Top speed shut off

huudoo · Aug 26, 2006

what would be the speed shut off on a 2004 4.6ltr
has anyone gone that fast
i was cruzing down 75 @100 mph @2500 rpm in 5th
i heard it was like 140 mph, i don't think that would be safe.

well, you wouldn't want to go 140 unless you had the right mods on your car, even then I wouldn't suggest it unless on the track or out in Wyoming with a state cop in your passenger seat.
These cars get unstable and squirrely at higher speeds....
As far as the governer goes, 140 sounds about right, but you can have that turned off....

No speed limiter on gt's equipt with the 17 inch wheels. Only on older models that had a 16 inch wheel option.

nwapache · Aug 26, 2006

really? that surprises me, I thought it was mandatory on all newer cars.....guess I learned something new

jstreet0204 · Aug 26, 2006

It has to do with the speed rating on the tires.

115 on cars without 17"s, and I'm pretty sure 145 otherwise- at least for convertibles.

i know that the limit for any US car is 155mph. i can tell you for a fact that they will go 148 mph in stock trim with gears. i havent found a road long enough to hit the rev limiter in 5th gear, but when i do i'll be sure to let you know. the only reason i didnt go faster was b/c the car wouldnt pull anymore. it was in 5th at about 4800rpm and just couldnt pull any harder.

I've heard more than one place (Bullitt archive maybe?) that the Bullitt has no top speed limiter, dunno about a GT though. I've had mine up to 148 on I-5, anyone in cali knows, LONG and FLAT and BORING. Sure made up for that. It getts pretty harry past 140, really keeps you on your toes.

Our cars really wont go 155 STOCK....so they didnt put one on the car. No need if the car wont do it.

I have personally been to 148MPH...completely stable. I could have drove with 1 hand....seriously.

same here i hit 148 on along stretch of the 10 interstate once but that was just to get it out of my system

hotmustang331 · Aug 26, 2006

Hmm alot of 148s huh? Must be the "magic" speed haha.

yea I only did it 1 time...thats enough for me.

Two of the '04 GT codes I looked at, one auto, one manual, both have speed limiters at 179 MPH and rev limiters at 6050 stock.

No wonder we never knew about it . Not many of us have the power to go that fast lol.

Stang|ess · Aug 27, 2006

I wasn't aware that there's a 155 limit. someone hasn't told chevy, ford or dodge about it.

I know that MB and BMW put limiters on their cars though.

gtstangau · Aug 27, 2006

I have toped her out on the interstate before it rolls up to about 150. The RPM's quit moving so I let off it. Only done it once and got it out of my system!

Mustang5L5 · Aug 27, 2006

No speed limiter...or at least a usable limiter.

On 99-00 cars with 16" wheels they came with H-rated tires so the limiter was set at 115-118MPH.

With 17" wheels and Z-rated tires there is no limit, but a stocvk GT doesn't really have the power to go past 150ish.

Mach 1's and 03+ Cobras have a 155 limiter.

I've been to 145 in mine, scary how stable it is at that speed. My fox sounds like it is going to fall apart at 120MPH

PonyboyIsaac · Aug 27, 2006

not trying to go with the popular number here but i went 148 when my car was bone stock, after the blower i went past 150 (around 153 maybe) but let off cause i chickened out.

ProCharger GT · Aug 27, 2006

Had the needle resting on the peg one evening, fastest I've ever gone..very fun!

hotmustang331 · Aug 28, 2006

^ I think im going to do that on the way back from GA for the heck of it, and because it shouldnt take very long then
There is an INSANELY long straight highway out there....trees seperate traffic (cant see the other side), an emergency turn around every mile, and public on/off ramps about every 10 miles....its insane lol.
