I couldnt tell, It was so slow but I stopped climbing at 148, kept it there for a couple seconds then let off.

I hit that on a slight downhill BTW, until that downhill I couldnt get over 147.

I believe that the top speed issue is from the drag coefficient and a lack of HP/TORQUE while stock.
There is not a governor on the MT. Other than design.

Now has anyone ever experienced that with a MT?

Nope

I've hit the fuel cutoff a couple times, but no governor. Boy is that an unsettling sensation.

But that was due to over revving the engine, correct? I think everybody has done that at least once.

Ditto with fuel cutoff..

It's like, moving forward and accelerating then instantly stops gaining momentum, sounds kind of odd too..

your "facts" are wrong. the US 6port 6mts have never had an electronic limiter. the proof is easily found on a dyno , at the track or now simply by using something like the cobb. you'll find thru reading that this info has been known since 2003.

i personally have seen 155 on a dyno

151mph this weekend, GPS confirmed, it took a slight downhill slope but when road level'ed it kept up. My oil light went off right after though

I was in 6th FYI. 5th doesn't get me past 137mph.

I'd argue that there isn't a governor for US MT 8s. I would have a hard time believing that a governor was added at a speed just past the stock drag-limited max speed. The main reason I don't believe there is a governor is from ... damn I can't find it. Still looking, but a youtube video.
On jack stands 6th gear, 180mph on the speedo. (5th hit the limiter at 153) If there was a governor anywhere before that, it would have kicked in, unless your going to argue that the computer knows that it really isn't going that fast?

Edit:
Here is is: http://www.youtube.com/watch?v=hE7p-D-PBeI

Edit:
Not saying 180mph is the top speed, since it doesn't look like he actually hit the rev limiter in 6th. Seems different from another one I saw that did a 0->186mph in 6th, not shifting on the way up, and it was a significantly faster rev, since he didn't have wheels/tires on. This one looks like it had some resistance to it, so probably still had the wheels/tires still on.

I've never hit the fuel cut-off, and I rev my car up all the time. I shift at 8500 or below; I see no reason to go over 8500, maybe there's a bit more power after that but I don't need it.
