Full JCW 210BHP "Kit" after 600 miles...
...Just turned 600 miles on my "kit" and I must say that the car seems to be "learning" more and more each and every day.
Throttle response has quickened appreciably since 50 miles or so and meteorically since "plain Cooper S days". My JCW MCS is soooooo quick to respond !!!
The "S-stumble" is almost non-existent and has been less evident with fewer occurrences as each day passes. Of late, over the past 3 days, no stumble at all.
The dreaded "yo-yo effect" is gone entirely. Good riddance to it.
The car is getting better and better mileage. I am up to 25.8mpg per computer and 24.4mpg via per tank (refill) calculation for in city only driving. Combined has yielded 29.7mpg per computer and 27.1mpg via per tank (refill) calculation. Highway only driving has yielded 36.8mpg per computer and 34mpg via per tank (refill) calculation. Not too shabby !!!!
My JCW MCS hauls proverbial butt through the gears so effortlessly that has basically lulled me into a sense of invincibility... Rice burners challenge me on a daily basis and I am happy in the knowledge that if I were foolish enough to race them on the street (which I am decidedly not) I would be assured of victory each and every time. Vettes beware !!!
I am riled by one nagging fact however... I have to wait another 650 miles before I can pass 4500 rpm in the rev range through the gears... and it has not been easy to keep my foot out of it. I think I am breaking out in hives from the act of supressing this urge... Oh well, got to be responsible... and take care of my JCW baby... Now off to the store for more calamine lotion as the "supression hives" are itching up a storm !!!
This was most definitely money well spent !
Oh, and one more thing....
JCW rules !!!
It is not how fast you go, but how you go.

Yes... that is the "complete" quote....

Since I don't go to the track anymore (to participate), I do all of my driving on the streets... and I do it responsibly... hence, it is not "how fast I go", but just simply "how I go" that matters to me most.
That said... I will not hesitate to "go fast" if I definitely need to... especially to avoid possible mishaps, and to leave annoying unsafe drivers way behind...

Ah yes, the waiting game! Having had the same kit installed in my 04, I can assure you that above 4500 is every bit as enjoyable and below 4500. However, I'll just offer something for consideration in the next 600 miles.
Most of us (guilty!) can't wait for the 1200 mark so we can "play up top". This was true for me when I bought Koopah and was certainly the case with the JCW 210 kit installation. Recently, I had a discussion with a race mechanic friend and he made a strong case for a "stepped" approach.
Evidently, we all try to keep things calm to 1200 miles, then goose the hell out of the engine after that; who can resist all that pent-up anticipation? According to my friend, this profile is not ideal; the parts "wear-in" then immediately fall under a sudden increase in "stress". And, while the Tritec can certainly take the stress, this may not be the best way to initially treat the engine.
Instead, he advocates stepping-up the demands on the engine gradually. To translate his principle into the MINI world would result in the run-in period being slightly longer but with a gradual increase in threshold limits throughout its duration. I think what he is saying would result in, say, three periods of increasing limits during 1500 miles. Miles 0 to 500 would be at limits well under 4500 rpm, miles 501 to 1000 would be at or near 4500, and the final 500 miles would be limited to 5500 rpm.
Of course, this is all theory. Plenty of people have used the spectrum of run-in approaches from immediately driving it like a rocket to strict observance of factory suggested run-in procedures. It would be interesting to bench test the variety of approaches to see if there are actually any differing results.
BTW-
According to information from my SA (at MINI of Peabody, MA), the 1200 mille run in period recommendation on the JCW documents is for kits installed in newly-delivered JCW MINIs. He recommended a 600-800 mile run-in for my MCS with 14,000 miles on it.

I am just happy not to own a big fast gas guzzling slab of rapidly depreciating plastic and s-glass !!!
Would like to mention that it is very ironic that most vette drivers do appear to me to be "medicated"!!!

I do not think I will be taking this advice... oh, and by the way, I think the break in rev-"limit" quoted by most informed parties is 4500 rpm not 4200 rpm...

After 600 miles I started to venture to revs above 4500 on my car. Short trips to 5000 and 5500 rpm's, just vary your speed and revs up and down constantly to brake in your motor properly. I took mine straight to redline in 3rd, 4th, and 5th at exactly 1250 miles. I've never subscribed to the baby a motor brake in school, not over the last 30 years and not for as long as I live. I felt my car loosened up at about 8000 miles, thats when it felt broken in and fuel consumption got most efficient. Mods started at 3000 miles, currently at 38000 and loving it. Enjoy your jcw, best of luck with it.

Glad to hear how happy you are with your JCW MCS. I'm very much on the fence about JCW vs. Aftermarket. Both seem to have strong followings. And there are definitely pro's and con's to each approach.
Hearing your happiness with your decision makes my decision tougher. Best of luck and happy motoring.

So in the end it is personal preference... "to each his own"... as we have heard many times on the forums... I chose the factory route because it is what I have always felt comfortable with. I am not saying it is better... just "better for me".
Best of luck with whatever you decide to do !

Okay, I resemble that remark - I'll have you know my Z06 is capable of 28+ mpg on the freeway (not too shabby for twice the hp of your JCW) and the smile on my face is from the acceleration g-force not the medication... But you're right about depreciation - boy did I get raped on this one... But as the saying goes... you gotta pay to play and the Z has been well worth the price of admission.

And intown mileage can and will eat a hole in one's wallet with a Z06. But, if you have a fat wallet then what does that matter... not much, right?
I imagine that a guy with i-forged wheels on his 'vette can easily afford a hefty gasoline bill each month... (g-d I love those wheels...).
Z06's are beautiful, (albeit heavy) pieces...uh... of exotic machinery... I will be the first one to admit that.
Seriously though... if they were made of double walled aluminum like the NSX would they not be even more fantastic?
I bet I love my Mini more than you love your Z06...
Stop picking on "my medications"... they have nothing to do with this... It is the medications that the American car designers are on that I would be concerned about if I were you bro'...
No harm no foul intended... just a little humor... you made me laugh as well! Thanks !

The iforged wheels are great but a pain to clean and polish and clean and polish and clean and polish- did I mention clean and polish? Guess what I did after diner tonight?
As far as more love for your car... my wife might beg to differ. Did I mention I cleaned and polished my rims after diner?
Don't know much about NSX's except what they look like in the rearview I do know that aluminum cars are a menace when it comes to door dings and bodywork. As far as the Z06 being heavy - that's news to me... at 3130 lbs its only 160 lbs more than the NSX which weights in at 2970 lbs costs $87,000 new and is shy of a full second slower to 60.
I'm inclined to agree with your comment about american auto makers - look at the GTO (coulda been great) - but they really got the Z06 right for the money. And I might point a finger at Chris Bangle's bungled BMW's if you want to talk about medication... I'll not have some of what he's smokin'. Didn't he also design the Aztek? Remind me again why BMW hired him?
If you've never been for a ride in a Z06, you owe yourself a trip around a few twisty blocks and down a good long straightaway. If you are ever in Los Angeles, look me up. I'll change your mind about my piece... "uh... of exotic machinery." BTW, congrats on the JCW.

And at today's gas prices.. I don't care how deep the pockets are - 101 octane @$ 4.00 a gallon is actually becoming a bargan here in LA. Not to mention a lightly used Z06 garage queen can be had for less than a new JCW Mini MCS at a Los Angeles dealership.

I do not dislike a well-maintained Z06... I think I would like your car... "you win" in that regard... It was just a well-intentioned ribbing..."at your expense"... I promise to quit that... at least in regard to your car...
Bangle??? I thought it was Bungle... or "Bungholio", as Beavis would say...
I have to disagree with you and your wife however... I love my car more... I change the oil every 5k. miles with Mobil1 0w40w... I flush fluids every 6 months, I wash it every other day and wax and detail it every month (sometimes sooner), and I sing it a little song when I "put it to bed" each night. This car is the reason my last GF left me...

More like my words are full of play-doh. Funny how things read without context or inflection.
Anyway, I certainly had no intention of stealing your thunder with a vette debate - I just thought it a perfect time to make a few jokes and defend my baby. Funny how I have to do that from time to time. Must be the image of the middle aged, gold chain, shirt-open type vette driver that has been forever burned into our collective subconscience. Believe me I had the same perception before I turned the key...
If you lived here in SoCal then you know my pain. Believe me it's only gotten WORSE since you left in 96 - particularly here inthe valley. If it weren't for my job, me, the wife, kid, mini, vette and the rest would be outta this burg...

The family and job (and toys) certainly sound like they make it bearable to live out there. I want to clarify that I was not conducting a "Corvette debate"... I was just "blurting out spur of the moment automotive rants".
Mine are the words full of "play-doh"... having never owned a Z06... and basically talking out of my a**.
This weekend... while driving around in my car with nowhere to go... I will think respectfully, of the fun you are having in your Z06...
Have a great Cali. weekend...
