Drivetrain John Cooper Works Tuning Kit R56
Ok...The kit is on my MINI.
Greg got it all ready in a few hours, I really do not know how many really but I will tomorrow when I go back.
I have left my Miltek exhaust on, to see what happens, I might put the JCW one to see the difference, at a later time.
I drove it for 10 miles and all in traffic. So, no fast runs yet, but it did pull harder from the red light.
I will go later to the sawgrass and run him a little.
More to come, I wish I would got a dyno first, but no time is the thing.

Thanks for posting your photos! My dealer told me the JCW Strut Brace would not fit. Looks like we have similar taste in Blue
My JCW Kit is on order
diablito - What kind of air filter comes with the JCW pkg? Is it just a paper filter? Does it look like there could be a generic K&N replacement for it?
it comes with a gold filter, why would you use a K&N the JCW filter is reusable besides if you need a new one is covered for 2 years as part of the warranty

National back order was 6 today is 1, zero kits in mount olive where the coding is done, you'll getit soon.
Yep according to the installation bulletin the strut brace is a no go.. but I had mine before and it seems to fit fine with good clearance. will see.

I guess I have always used K&N Filters on my cars, so I have an bias against to paper filters. I contacted K&N but they have no direct replacement right now unless I measure and see if one of their existing/custom ones fit like it did for the R53 JCW.

Yep i like the milltek sound I have the JCW exhaust and the JCW tips are sick ..bigger then the JCW tips on the R53 JCW kit...I am toying with the idea of putting it on just to see, but maybe I will sell it to recup some cash and go to the next upgrade...Recaros!

Prolly just wishful thinking on my part.
I'm sure if you bought the JCW setup you could just have them reflash your car and then turn around and sell the intake and exhaust... not sure if it'd be worth the money though..
You can do that, I left my exhaust, its a milltek, and I will probably get a different intake later when they come up with something that does not make my MINI sound like a diesel with an open element. 
The JCW exhaust list for over 6 bills and it's up for grabs at any mini dealer, The tips are huge, they look nice, I am very tmpted to install it to hear it roar.
Each badge sells for around 100 so you can recup a little bit of the investment. and still have your warranties.
Today I learn that, if you buy the stageI after you took delivery comes with a 2 year warranty, if you get it installed before delivery has the full 4 years.
My MINI drives stronger today than yesterday, weird maybe the programming is getting comfy on it's new ECU home...
well worth it, to me.

Ya might want to double check that. I'm 95% sure that it is covered for the remainder of the factory MINI warranty or 2 years whichever is longer.
after one has taken delivery its cover like you said above.
Can you still open the Air box without taking off the Strut Brace?
The numbers from MINI compare the kit to a JCW R53. Does anyone have numbers that compare the R56 kit with a stock R56?
I'm interested in the high gear roll ons (50-75 in 4th 5th and 6th). There are too many variables that make a comparison to an R53 worthwhile.
My suspicion is the numbers are not different enough to publicize them.
Any opinions?

Well, the HP and torque curve are right there on the MINIUSA site, so...
soon people will probably post dyno's on something we can compare to
I'm looking for the figures that compare to their published PR, i.e. 50-75 in 4th, 5th and 6th gear for a stock R56
R56 JCW R53 JCW
0-60 mph 6.5s 6.5s
50 – 75mph (4th gear) 5.3s
6.4s 50 – 75mph (5th gear) 6.6s 6.7s
50 – 75mph (6th gear) 7.6s 8.9s
Of course, once those dyno results are posted, there will of course be the flurry of posts on how dynos are totally inaccurate when measuting turbo cars and how five different variable scewed the results and it's all wrong.
Basiclly the reality is go for what you like and what you're comfortable with. The S in stock form is more car than 99% of us will utilize anyway. Most of these mods are therefore charcter boosters. Get what sounds & looks the best (and your dealer will support - if you care about that sort of thing).
3rd and up it needs more
What reasons I am interested in the kit for does not apply. I just want straight facts. A test drive of a JCW R56 will be the deciding factor, not what you think is adequate for that car. And yes, I do care what the dealer will support on a new car.

Which is why I'd like to see the comparitive numbers to a stock car. I think a stock car's 50-75 times in 6th will be closer to the R56 JCW(7.6secs) than the R53 JCW (8.9), which is why they don't publish those figures. And what loss are you referring to? The inaccurate graph or something else?

In the UK a JCW brochure has been released in the past few weeks including a couple of pages on the tuning kit. It shows a much more sensible looking graph, the torque curve shape is almost identical to stock and so is the power curve until it reaches around 5k where the stock car tails off but the JCW reaches full power.
Has anyone had the JCW engine kit installed in the So.Cal area? The dealer where I purchased the car (Long Beach) has not done any installs. I haven't taken delivery of the car yet and wanted to get it done before, because of the longer 4yr warranty. After talking to the service advisor there my confidence has dwindled, they didn't seam to know much about it, even asked me for part numbers! and couldn't give me an install price. Anyone know of any dealers in so cal who have experience with this kit? Thanks
"The John Cooper Works kit is sold and professionally installed through all MINI dealers in the U.S. A MINI Cooper S equipped with the dealer-installed package is fully backed by MINI’s 4 year, 50,000-mile new car warranty. Owners of an existing MINI Cooper S may visit their local MINI dealer and have the kit installed at any time. The balance of the factory warranty will still remain in effect. The full 2007 John Cooper Works kit retails for $2,100.00 plus a recommended 2 hours of labor for installation."
So remaining warrany or two years/20K... whichever is longer.

Update - I recived a call from my dealer. My JCW Kit is in

WELL. While none of the JCW parts, if done aftermarket, would void a warranty (MAYBE a chip, but I had the madness ECU flash and was fine @ my dealer)
- any problems coming from them, like RATTLES (I had some from my magnaflow on the cooper), etc.,
I still find the dealer taking responsible for that stuff appealing... With my heavy modded 05 cooper there were a good number of silly things that started to go wrong and with the JCW, maybe it's not quite as much, and too expensive, but there are gives and takes everywhere over this...
