2004 300M Speed limiter?

Probably. Do a search on the 300M Enthusiasts Club forums
(http://300mclub.10­0megs42.com/forums/i­ndex.php) - they discuss the
subject there almost constantly - what the limits are for the various
options, how to defeat or raise it, etc. The limit is set at different
speeds for different options packages, and IIRC, the Special does not
have one, and maybe European versions, so - yeah - I assume most 04's
have a limit. Usually the limit will be set right at the speed rating
of the tires that come on the particular unit (or, probably more
correctly, they only put tires on at the factory that are rated for the
limit that is programed into that particular unit).

 Not sure about this car but some speed limiters are put in place because the
car was only designed to go that fast.

On some Ford products the speed limiter is in place not only because of tires
but the torque convertor implodes at higher RPM's, the drive / half shafts are
not properly balanced for higher speeds, the brakes are not designed to do
their job at that speed. The same car in a sport edition had no limiter because
these under the hood issues were addressed in this more expensive sport model.

This is what happens when you rely on matter-antimatter reactions for
propulsion, and the matter injectors get clogged.

I almost cried when I verified this for sure. I’ve had this car for
about 2yrs now (bought it for my wife in May of ’03) and just recently
bought her a new Jeep and decided it was time for me to ’take one for
the team’ and take the old car :)­ She said she couldn’t stand it any
more. I’ve driven it over 100 on numerous occasions, but only for a
few seconds at a time because I’ve never had radar detection or any
kind of laser protection set up on it like I’m working on now. But
when I took it up near KCI airport to knock the cob webs out of it and
got it up to 100MPH and the gas shut off, I could feel my heart
breaking! I knew I was in for a challenge. My question is this: can I
simply get the ECU ’re-programmed,’ or do I have to install a
jack-legged contraption someone put together in their garage like I’ve
heard about that creates a ’loop’ electronically in the computer when
you flip a switch and cuts your speedo in half (consequently also
keeping half the miles off your car and making it illegal as hell)?
I think for safety’s sake, the limiter is put in place more for the
brakes than anything. The suspension on that vehicle would be the next
concern, but it, too, should be safe up to at least 130mph. The tires
that come on the standard model like mine are "T-rated," which means
they are tested with simulated road force by rolling them on a barrel
for over 2hrs at 118mph, and that is the limit at which they begin to
fail. I sell tires for a living. First time posting here.

According to my reading on the 300M forums (link given in an earlier
post in this thread), Kenne Bell is the only company the experienced
300M owners trust to reprogram their ECM's, and they can modify or
remove the speed limiter with a signed waiver. Do a search on "Kenne
Bell" on the 300M Club forums, and you'll have some reading to do.

I was thinking the limit on the standard LH cars was 118 mph (I saw
where you corrected your post to 110, but I thought it was 118), but I
could be wrong. Anyway - do your reading - you'll find the answers.
The limits are based on tires. AFAIK, the European M's have no limiter
and have essentially the same brakes (possibly different pads).

At least one guy there does use the speed ratio device, but he has the
Kenne Bell programing and no speed limiter - so that's not why he uses
it. He has the ratio device because he has special gearing (Pro-Prowler
I think) and it actually corrects his speedo reading (see
http://300mclub.100­megs42.com/forums/vi­ewtopic.php?t=8352)

Gotta be.... I've had the wife's 93 over 110 without hitting a limiter.
Can't say I've ever passed 118, but definitely beyond 110. Once. Years
ago. On a very empty, very straight, very long country road on a clear
bright day.

 This is a curious discussion. Never knew such things existed at such low
speeds.

In European cars I have only heard of the 250 km/h (155 mph) limit in some
cars such as Merc and BMW. This is voluntary no doubt so that largely
untrained drivers don't kill themselves even quicker.

A few years ago I hit a nominal 120 mph in my 1993 2-litre Merc 190E,
admittedly taking a while to get there.

With my newer 3.2 l car I can get there a lot quicker, of course. :-)­

<sigh>

We didn't ALWAYS used to be such "safety wussies" in the US. My '69
Dodge speedometer goes to 150 mph, as did many muscle cars of the era
and it was something of a bragging point in those times. With the right
gearing, those cars can *bury* the needle, too. But many were geared for
drag racing and top out at 110-120 mph, limited by the redline of the
engine and lack of an overdrive gear ;-)­

OTOH, its hard to think of any road within 150 mile radius of where I
live that I'd feel comfortable driving over 100mph on anymore. Too many
cars (I should say 'too many MINIVANS'), too many drivers on cellphones.

 Whaddaya mean? I have been on lots of wide roads with central reservation
in the US. The surface may sometimes leave something to be desired, but
exceeding hundred (mph) in a modern car should not be too difficult,
assuming a quiet road (and a will to take a legal risk). Indeed, I remember
reaching 92 mph or more some years back in Pennsylvania. There was still
some 'oomph' left but the car's road-holding capability was reaching its
limit on that road.

How do I remember the speed? A couple of gentlemen from the local
constabulary took issue with my speed given it was a 65 mph zone and handed
me a ticket ... :-)­

In Britain we don't have 'Autobahns' either and our motorways seem to be a
touch narrower than the German ones, but we can still hit the ton (when
noone's looking).

Sigh

I'm guessing that not all dealers will be willing to do that flash (or
may require a waiver) for liability concerns.

There are plenty within 200 miles (if I go west), but its just too
populous around here to drive the way I (sometimes :-p­ ) did 30 years
