112 seems to be about all I can get out of it.

2002 MC

This sound right?

 

Obviously you are doing that on the track, otherwise per site guidelines:

you would not be posting this here.

 

Uhmmm ... sure.

 

CVT or manual? I though the Cooper was electronically limited to 120ish?

I've hit 125 mph on the front straight of Texas World Speedway before diving down into turn 1, so I know my car at least goes that fast... 2003 Cooper, CAI and cat-back and MTH, 5-speed...

 

This was in 5th gear too, so it might just be short on power to turn higher speeds in 5th gear. Although, I wanna say once in 4th it stopped pulling right about there, but was at somewhere close to 6500 rpm.

 

We hit the speed limiter (Professional driver on a closed course) on my 04 MCS. It didn't make much difference since I think indicated 135 was all it would do anyway. It did continue to gain speed in 6th gear.

 

The MC is limited to 124 mph and the MCS to 136 mph, but I'm not sure if that's actual speed or speedometer display (speedo reads fast; more so as speed increases).

 

There is no speed limiter. The only thing limiting the speed is aerodynamics. Raise the horsepower and you can hit a higher speed.

 

I had always heard the were limited at 135 (136). Maybe it is only limited by the horsepower. When I hit it nothing exciting happened, we were just out of steam. I always imagined it was going to be like the rev limiter but it wasn't.

 

ONCE more

There are NO electronic speed limiters ... there ought to be a FAQ on this somewhere. Rev limiter yes .... speed limiter NO

its all in the aerodynamics (and gearing). Many threads on this:impatient

 

Sorry, I'm just repeating what (I thought) I read in the MINI brochure. Never paid much attention to these threads because I don't plan on driving 124 mph.

 

the CVT will do 130+ tested that a few years back with Stoopids Cooper cause it has 6 gears... so there is one benifit of the CVT! LOL

the MCS is 136 from the factory... 136.8 LOL

 

I was directing that at you Chris, but just in general because this just came up like two days ago ... with lots of posts

The car is brick with a cd of .36. It just hits a brick wall because it needs much more HP to go faster. The easiest way to see this is just look at the MCS spec vs the MCS JCW spec. One says top speed 136 while the JCW says 142. So 40 more bhp gets you 6 mph. But the curve is not linear. You just cant say another 40 bhp gets another 6mph, probably more like 3.

 

The brochures say it, but it isnt true.

 

OK but gearing is a mechanical linkage, limit the engine speed and the cars top speed is limited, making that a contradictory statement.

 

Gearing makes a huge difference. A lower number means slower acceleration but higher potential top speed. A larger number means quicker acceleration but lower top speed. If you aint got the HP, your not going to hit the redline in the top gear.

Just look at muscle car gearing ... 4:11 to start up to 5+. The cars were meant for the quarter mile but topped out .... if you got it right, with their top end near the quarter mile speed.

02 - 04 cars have a theoretical top speed of 164 IF you got the HP. 05/06 less. Again, look at the Silver State classic, there is an 04 MINI in there with 164 top end in 2004 run. (pretty sure it was 2004).

 

the car is electronicaly limited.... like most US imports... I know because I have taken mine off... by messing around with the ECU.... other softwares also do this...

infact there are sperate ones that effect different things.. some rev limiter... some accually effect the throttle body... Like 6th gear.. even though I am planted at 100% throttle the ECU accually tell the throttle body to hold at 50% making it so that in 6th I cannot get over 145 where as in 5th I can go over 150 by taking it to my red line... I'll find that one soon!!

 

I bow to your greater wisdom in this area if true but this really needs to be in a FAQ somewhere. With the technical details because there is a lot of misinformation out there including ME! in this area

 

On my truck, also an electronic throttle, when the speed limiter is approached, it starts pulling throttle until the speed limit is reached. When this happens, it closes the TB just enough to hold the speed (stock 99mph). This is what I've always alled, and heard called, a soft limiter, rather than a hard limiter that just cuts fuel, like the rev limiter.

 

EXACTLY what I thought was going on.

How do you do your own tuning on the car?

 

PLEASE PM me or email me if you would rather.

I'm an LS1 tuner (truck tuner actually), but it's still all the same principally. I would LOVE to be able to mess with my wifes MINI.

 

I grew up with cars and workin on them with my family and friends... with the mini I was fortunate to hook up with Hubie from Fireballed Racing... during that time I had the opportunity to do alot of things... on of them was work to try to find such limits like the speed and rev etc...

 

So ... no software or anything like that to mess with????

 

Thanks Tuls, someday I'll get around to messing with my ECU, but I need a relable car for the time being.
