Hi, hoping you can help me out here as a newbie, maybe this stuff has been covered in a previous thread, anyway....

I have a few questions regarding the 05 MCS mechanical changes, loads of info on all the cosmetic tweaks but very little on the mechanical info. Here goes...

Power is up to 170 bhp, how has this been achieved?
(Dealers seem unable to tell me)

Has the S gearbox been changed? If so how?
(I heard the box had a slightly shorter shift from the old one and the gear ratios are now closer, again dealers said no, only the one and coop boxes were changed)

I have now read a thread stating that the exhaust has been changed, is this true?

Any other info would be greatly appreciated.

Since this is an international forum and we all live in different time zones, it's best to wait a whole day before expecting many responses. I did manage to dig up a few tidbits for you. Hope they are helpful.

Look here: http://www.motoringfile.com/2004/02/01/the_2005_mini_revealed

Scroll down and you'll see this:

Cooper S now with a revised supercharger, revised exhaust system, and new ECU - 170hp and 162 lb-ft of torque. Top speed is increased to 138mph and 0-60 times should improve slightly as well. The MCS also has shorter gearing in 3rd, 4th and 5th gears for quicker acceleration. (as discussed previously)
One and Cooper now with a Getrag 5-speed with shorter gearing for quicker accelerations. The Cooper will also have a slight increase of torque as well.(as discussed previously)

Look here, and you'll learn a few more details: http://www.motoringfile.com/2004/04/23/official_news_on_the_2005_mini_refresh

I believe that the supercharger is now the "fifth generation" with coated vanes, which only the JCW had before. I beleive the extra horsepower was achieved with a revised exhaust system, which has a characteristic popping sound when the accelerator is let up. This "burbling" sound is meant to be there - it is not a defect. In the U.S. the engine is rated at 168 HP. Not sure if this is a rounding error, reduction due to emission tuning, or some other U.S. specific problem.

The shocks in the MCS have been changed to ride better with the 17" S-Lites and runflat tires. Gas pressure and rebound rates are softened to smooth out the ride. It really works.

UK MCS is rated at 170 BHP not 170 PS.

The difference may be due to Octane ratings or something about which I have no idea.

We seem to get 2BHP more than you guys tho :D

Well I want the stiffer shocks. I put 225/45/17's on and they rub on the rear tires when I hit a big bump, or a small bump with the family in the car.

Any way to stiffen the stock shocks?

There gonna rub anyway your overall diameter is too big. You can calculate your diameter by doing (.45*225mm)*2 then convert to inches and add 17. Your diameter is about 25" Stock is closer to 24". So I imagine it would be difficult not to have them rub considering the added width.

I have heard other people go with the 225 but I'm not sure why. It adds weight and makes your gearing taller.
