Are you member? Have you experienced that momentary engine stall? Have you put those 208 ponies to work? Have you felt the most intense speed you will feel out of our detuned m274's? Then this is the place for you.

I had a stretch of essentially bridge road heading the St. Pete I was able to "join" on. Its nifty enough. Very smooth shutdown.

So put [her] on a highway
And show [her] a sign
And take it to the limit one more time...

I accidentally got to 95 tonight. It runs so smooth and easy, all of a sudden I looked down at the speedo and was glad there were no cops around!

What is this momentary engine stall?? I have driven plenty of buses with governors on them, is that not what the Metris has at 101?

Relax....... That is my old broken speedo, while arriving at the dealer for its first service A. It couldn't have had better timing. All is well now :)

I'd try it out for yourself- I go 90 on the turnpike regularly, and have hit the limiter on it.

It's not really a stall. It's more like a sudden loss of acceleration. A bus when it hits a limiter is already close to all it can do. A Vito with less 13 less horsepower is electronically limited to 124 (200kmh), and I've heard they can do about 132 if you choke the limiter. So figure a Metris can do at least that, maybe 140. The feeling of a vehicle losing acceleration is different when it's at 95% of top end then when it's at 60% of top end.

Yep, I joined about 1 month after ownership. I stay 'active' in this 101 Club every so often. If I had the choice right now, I wouldn't remove the limiter completely...but would have it raised to 125. Anything faster with that weight, height, tires, and tiny brakes is just asking for trouble.

I'm jealous.

I mean, I could go for it, but in Ontario a law was introduced a few years ago that stipulates that the penalty for going 50kph ove the limit is a roadside suspension of licence and vehicle confiscation as well as a fine as high as 10k$. Our highways have a lame 100kph speed limit, ergo, the 160-something is not attainable to me.

Well, it is, but I'm not messing with this particular penalty. That being said, I regularly cruise at 145kph and can only dream of something better. Maybe when I travel out west this summer where some places have higher speed limits and no "racing" laws. Here's hoping.

I joined that club last July about 2 months into ownership (waited till I was over about 1,500 miles on the engine). Easily hit the limiter, still smooth! I agree its more like a "loss of acceleration"....it could go much faster if *allowed* to.

101 is slow though....I've gone....much faster, in my 420SEL..... I think my bluetec has a 130 limiter but I've never tried it. It only turns about 2,600rpm at 100mph. Wish we could have that engine in the Metris!!!

Fastest I've ever been was at the limiter of a 2002 C220cdi wagon on the autobahn.....155mph! Stuff gets REAL at those speeds.


Even my ancient 1982 300SD would top out (at 5,200rpm) at 112mph.....sounded more like a prop plane than a car at those speeds/revs....

I didn’t know this was a thing ...

And she’s really limited to 101?
Because she moves towards that rather fast and eagerly.

I guess one of the long causeway bridges in the TPA - St Pete area may be good for a quick push on the throttle?

It hits it pretty quick if you punch it from 75 or 80 mph; you really don’t need that much distance. I hit it regularly on the PA and NJ turnpikes, partially as a matter of so-called “Italian tuneup”. As an EGR equipped direct injection engine, the M274 is prone to carbon build-up, so running it up to speed while keeping the engine in the 5k + range once in a while helps blow some of that sludge out of there.

Fuel additives don’t do anything about carbon build up on DI engines; anything that tells you otherwise is nonsense. The problem with DI engines is carbon builds up in the intake and valves, but because the fuel is injected directly into the cylinder, nothing washes it off... so increasing the detergency of the fuel that never touches it does nothing at all.

The only non-disassembly solution is to increase temperature and air pressure at the same time for a somewhat extended period of time- a minute or two is my thought, -which will cause some of the carbon buildup to fall into the cylinder and get vaporized. It is important to keep in mind that this kind of operation invariably ALSO leads to increased wear and stress on the engine components, so it is something you should do only occasionally, particularly if your fuel economy starts dropping substantially for no apparent reason.

Addendum: There is nothing wrong with running it at 101mph all day long if conditions warrant. The thing I’m warning moderation about is high-load, high-RPM, accelerating driving. 101 in 7th isn’t going to stress it, especially on a flat road.
