Hi Guys, I borrowed a Turbo MCS from the dealer today. One thing we were keen to try was the Sport Button. Aside from steering weighting ,I would expect the car to accelerate more quickly (Even if only for 4 seconds) with it on than off? Anyway at wide open throotle the accelaration at any rpm either on or off felt the same to me,so we decided to time it! !
We did 4 runs with the button off from 2000 to 6000 rpm ,two runs in second gear & two runs in third gear. We then repeated with Sport 'on'. The results were (averaged out) that it was faster (ie it took less time) with it off ! This was only 0.1 seconds,so I suspect it was actually the same.
The light came on so I dont think it was faulty. -Next time I'll hook up a boost guage and see if theres any increase with it on.
Best Regards Roland GTT

Could be faulty, as even my butt-o-meter can feel a difference. But then again I'm not a scientist or expert in this area. As far as I understand it doesn't change the power, and it's power that affects the 0-60, it just changes "throttle" (using term losely on the MCS) response and behaviour. IE if you 're driving along and blip/press quickly the pedal with it on the response is faster/sharper.

I must admit i couldnt feel any difference when i tried it!

I think they should explain this 'improved throttle response' a bit more. If you are 'going for gold' your pedal will be on the metal, so unless with 'pedal to the metal ' the throttle is not actually fully open with sport button off, and only opens fully with it on then its not going to make the car any quicker.
What I need is 2 boost guages connected one either side of the throttle and compare readings with 'pedal to the metal' with sport on & off. If with sport off the post throttle boost is less we know the throttle is opening less. If both the pre& post throttle body boost pressure is higher with sport on, then we know it always achieves full throttle opening ,but bleeds off more to the turbo actuator to increase boost / power. The latter is what I would expect BM to do ,its just that its so minimal it cant be felt or measured (for me anyway)
Best Regards Roland GTT

I feel the difference. But they should come out with a seperate manual for it

[MINIAC]

I read somewhere about an "extra amount of torque" being available for a limited time during hard acceleration. Is this available only with the Sport button "on"?

[Fin]

I would have thought the sport button would have allowed the overboost 260Nm torque to be utilised, wheras the ~240Nm would be the norm whilst it was turned off. It's the torque that gives you the 'pushed into your seat' feeling. If the button was on but you can't feel a difference, maybe it was faulty.

I'd have the button switched on all the time anyway!

[MINIAC]

is the word I was looking for ... thanks

[Paul]

That wouldnt explain how it affects throttle response on the Cooper though would it.

[Fin]

Is it stated that it does affect the throttle response on the cooper? Or does it just tighten up the steering?

[CC07ERS]

sport button this a gimmick i think but still will be pushin it regularly

[Paul]

A gimmick? So you've not used it? The steering difference is worth it alone in my opinion.

only had a test drive today forgot about it also 6th gear too

You sure you wasn't just on a brisk walk????

[CC07ERS]

well the salegirl who was stunning nearly had a fit when i gave the cae the boot

[thrud]

Definately not a gimmick. It makes a big difference to the car in my opinion. No overall increase in power if you have your foot flat down, but a major improvement to the responsiveness and steering feel otherwise.

I don;'t know about all the techo babble that the tuner guys use. I notice the difference especially when you switch the sport button of.

So the sports button improves the steering - why not have the steering this good all the time and remove the button. Essentially it is a remove-quality-in-steering button, it's just they got the on and off the wrong way round

Gimick - for sure!

Cheers,

I don't think it's a gimmick. Admittedly I haven't tried it yet, but I like the sound of the steering loosening up slightly when the sport button is off, as it would be better for motorway journeys

[MINIMANIAUK]

I dont believe its a gimmick, I suspect due to the very high compression ratio which was used to improve the off boost performance ,the higher overboost limit has limitations and could effect reliability , its a good design for a road car giving good low down torque and response and making it less peaky/turbo like . but it hints at the route of more boost pressure being a no-no. high compression and elevated boost are not a good mix ,and to make an engine capeable of both not cheap!
powder forged pistons , ceramic coatings, and a whole host of other things would be required ,not the remit of a volume production car ,and fuel quality world wide would become a major issue
