Gear Ratio
 

I give up, 3 weeks I've been trying to find the gear ratio of my 05 MCS and I still haven't found it, what the hell is the gearing in the 05?

And is it a different ratio with 6 spds vs automatic?:confused:

I would have liked to find this info myself but as hard as I tried I came up empty. :sad:

Thanks, now I have the transmission ratio, all I need to find now is the final drive, or ring and pinion ratio.

Those are overall ratios, so they already take the final drives (there are two final drives) into consideration.

I guess I'm just not familiar with front wheel drive, after looking at the picture of the cutout, I see the differential is right in the transmission, si it's not like a normal 6 speeds where you have a driveshaft going to a pinion driving a crown gear, I guess this is all new to me, time to find a service manual ASAP.
Now where do I get one of those?

R U serious??

this mad info. ur after, what do u need it for?

Oups!!! As you can see I edited my previous post after looking at the picture, boy do I have to start learning all over again :razz:

I was curious as to why this little car revs so high in 6th at 70 mph, in my Vette, I have a 6 speed and a 4:10 gear and I barely get 2k rpm at 70 mph but I also know my 1st is 2:68, 2nd is 1.80, 3rd is 1.29, 4th is 1.0, 5th is 0.75 and 6th is 0.50 and with a 4:10, it doesn't rev nearly as high as the MINI, so I tought I'd check how they are geared but I guess I should just forget about that one with a front wheel drive, as you said <What do I need it for?>

yea i saw that now (ur edit) i have a 700r auto in my 63' chevy W/4:11's rears & it revs kool, and thats a 4speed but does not rev higher than mini cars!?!? i often wonder why myself. but it sure feels good to be able to down shift to 5th & take off nice and strong tru 6th

5.7 liters -vs- 1.6 liters? :lol: The MINI would be an absolute dog in 6th if it ticked over at 2k at 70 mph. Probably good fuel economy though. :thumbsup:

BTW, Quaife offers a dog-engagement trans for the MCS (bye bye, synchros):

And MINI Mania offers a gearbox with different ratios as well:

They now sell final drive ratio with straight cut gear but I still haven't found what the stock final drive is and they don't tell you what the aftermarket one is either but there are people who actually bought this for $2100 installed :razz:

I wouldn't spend money on something I don't know what change it will do if any.

So far I finally found one spec done the way I'm used to but it had to be for the Automatic:
AISIN Automatic
Gear ratio 1st / 2nd / 3rd
4,044 / 2,371 / 1,556
Gear ratio 4th / 5th / 6th
1,159 / 0,852 / 0,672
Reverse gear ratio
3,193
Final drive ratio
3.683


At least now I know the final drive on the Auto is 3.683, maybe if I live old enough I might one day find the same description for the 05' 6 speed without getting the overall ratio, I'm used to specs the way this auto is shown, why is it so difficult to have the same specs on a 6 speed is beyond me :confused: .

better economy at high freeway speeds would be great
 

>The MINI would be an absolute dog in 6th if it ticked over at 2k at 70 mph. Probably good fuel economy though.

I'm assuming MINI chose to let the MCS rev high at freeway speeds in order to keep the sweet spot of the supercharger available on demand. Personally, I'd have prefered lower RPMs and better mileage when I'm going 70, and making a quick and fun downshift whenever I need a sudden burst of power.

Of course, I'm not an automotive engineer and therefore lack a full understanding of the tradeoffs involved.

My wife's Pontiac Vibe behaves like that, top gear is well below the torque peak at freeway speeds. Let me tell you, it's really annoying to have to downshift from 5th to 3rd just to maintain speed on the gradual grades found on Interstates. Conversely, it's great that in the MCS, I haven't found any occasions where I NEED to downshift from 6th (of course lots of times when I CHOOSE to though). :wink:

Gearing is matched - or should be - the the engines power curve characterisitcs...and perhaps aerodynamics where top end is concerned.

Very intersting that many aero race cars must incorporate aero forces acting on the tires - tire deflection - into top end gearing...the tires circumference shinks due to aero forces, whereas, ours grow.

I don't understand what the fuss is all about. The gear ratios are ideal for every county in the world (especially the USA) except the one I'm living in right now. My fuel economy is in the teens at the highway speeds I can legally drive. I need a 7th gear (could use an 8th too).

well, the cooper doesnt have overdrive. From 4th to 5th the RPMs drop about 1000 RPMs. 83MPH-4500RPM. I taking it on the highway, but love it on the Backroads!:lol:
