Hello
I am owner of a Mini Cooper S JCW 05 (210Hp) and wanted a little more power.
I am thinking do a remap over JCW file.
I go to modify the Intercooler (DFIC or GRS), which your opinion of I only Remap?

I go to have profits with the introduction of a new File?

Thanks

Best Regards

 

First off, some have proven, perhaps inconclusively, that the JCW does not make 210 Hp in any form straight from the factory.
I don't know what other mods you have on your Mini but I would start with a some suspension improvements like a larger rear stabilizer Bar.

If you want the car to feel quicker and more responsive, Get lighter wheels and tires, and add a RSB You'd be surprised how much of a difference in ride that alone will have. (Even just going from run-flats to lighter tires has a huge effect!).

 

You could get a better intercooler, such as Alta or M7 DFIC.

An ECU remap will not give much HP, but will improve smoothness. A JCW kit should be very smooth so I would not spend $$ on that.

I suggest lighter wheels & getting rid of the run-flats.

Also, you might want to improve brakes & suspension... Stainless steel brake lines, better pads, brake fluid. A rear swaybar is a really nice improvement! I love mine and believe it a a must-have for any MINI! (Cooper & S)

 

Dont bother with any re-maps of software upgrades.

I tried the MTH software and it ended up being a waste of $.

The JCW kit has tons of power and willl provide you with lots of big

Here is what I would suggest:

1. Concentrate on the handling departement. talk with a local tuner and discuss options.
2. Wheels and tires. Lighter wheels and better tires, non-rf.
3. Get a resonator eliminator for your exhaust!

Bottom line is to leave the engine alone since you already invested in that area. Look elsewhere forupgrades.

Just curious what your source is on this? I have a JCW and have no reason to doubt the power claims. (Actually 207hp)

 

I respect those who seek one more, five more, fifteen more hp...ect for their JCW. That's great and all and there have been other cars that I've tried to bump up the hp's but..........IT'S A JCW!!!!
I love how my JCW screams, right out of the box. 207, 210, who cares!
All I know is that I plant my right foot and I can't stop grinning!

 

Amen brother!!!!!!!

 

I have an 06 JCW, I recently removed the flap from the air box (free). Bought a K&N high flow air filter 36.00 at auto zone. part number RU-3130 any auto part store can order it for you. OBX headder from ebay brand new shipped 197.00 installed my self (free) check the how to section for great instructions. I elminated the resinator $4 at auto zone for straight pipe cut and attached this my self but needed a muffler shop to weld it completely and also had them remove the flat spot before the muffler split. (50 dollars)

night and day diffrence I can believe how much more power the car has and its faster much faster for the money I spent.
I dyno'd the car about 2 months ago to get a base line the peak hp was 170whp, I'll dyno it next month at a local car show and see what it does I know there should be a nice diffrence.

Cam and better head on its way.

By the way total price was about 300.00 and well worth it and my car still looks like a jcw same intake but much better, same exaust but much better, headder almost unnoticable with heat sheild in place. I love the way the exaust sounds when I'm on the gas.:thumb sup:

 

Hi

I have a 2005 JCW, dyno'd at 170HP last year.
I had the Fieballed ECU remap installed, the main effect of which was to break the rev limiter, (together with a bunch of other smoothing changes)

Last years dyno was measured around 6000rpm and appeared to be just reducing. This year we did a first run at 6500 and the graph was still climbing, so we did second an third runs at 7500. This time we peaked at 182HP and again appeared to be just breaking off. This works out to be around 235 at the flywheel.

So basically, not a whole handful of power improvements, but I have now got the capability to get the higher revs to get the higher power.

The whole package gives me incredibly faster shifting (at around 7200-7500), as it does not drop off so quick, so I stay well up in the power band.

I already smiled when I put my foot down, now it's wider!

I did the Dinan Lg. bore throttle body to my '05 JCW and absolutley love the crisper throttle and strong pull all the way through the RPM range. (use to feel like it was droping off a little at the top end in 3/4/5 not any more )

Oh and as far as the MTH software, which file? Standard or Tuner was it that you (minibull2) tried, was all set up to get my download process started next week, seems like lots of others are very happy with it, but I'm sure most of them were'nt starting with JCW cars.

Hello
Thanks for Reply my topic, your opinions are very important...

1st - My car are a 2005 JCW (never Dynotested), what I want is a better response b[FONT=Arial]etween[/FONT] 3500rpm and 6500rpm. I Think that I can take greater advantage from Kit JCW with a better remap, do you agree?

2nd - I have a 17" Wheel 8Kg (18lb) with non-runflat tires (Continental ContiSportContact) 9Kg (20lb). The car is better grip, but I do not notice great profits in acceleration...

3rd - My Rear and Front pads are DS2500, and am very satisfied with the performance of the pads... For now I go to keep this setup, later I make the upgrade for Wilwood

4th - I go to upgrade my suspension, Coilover KW V1...

- What your opinion of Evothec File? It is a good choice?

One more time thanks

Note: Pictures of my MINI post #8

Best Regards

 

If your just looking for responsiveness I still think the throttle body change is a must, I would never go back, but you might want to read my post in this thread also:
https://www.northamericanmotoring.co...ad.php?t=89039

As far as a remap I still haven't got a response to my earlier question about what kind of file minibull2 was refering to, standard or tuner? I myself am going to go ahead and do the MTH tuner file, so far I've heard more good than bad.

 

Not making 210hp? This is the dyno run file of my wife's 06 JCW, completely stock, three days after we picked it up and about 500 miles on the odometer.

If you don't have WinPEP to load it, the peak HP/TQ is: 181.32hp/158.54tq.

Assuming the typical 15% drivetrain loss, we're looking at almost 215 crank hp.

 

I may be wrong, but I think the Euro-spec'ed JCW MCS cars are 210. MCSJW does live in Portugal, you realize.

 

not sure if they have been upgaded, but how bout picking up some headers that should give you some mid range power

 

Hello my MINI Friends
Before more, thanks a lot to all. I am learning very with your answers and your advice. Thanks for reply my Topic, have been very important to me.

Like "dimini" said, I´m from Portugal... I never dynotested my JCW, but a friend of mine did it and the results had been: 132.6Kw (180.2Hp) and 210.5Nm of Torque. I think the problem is the high temperature at Intercooler...

Let me see if I understood, the advice are:
- Throttle body, with is mod my car goes to spend more gasoline? Somebody had some problem with this alteration?
- Header, what do you think about Supersprint with JCW exaust?
- Intercooler, DFIC or Alta V.2... GRS is not a good choice?

Definitively do not recommend a remap... here in Portugal it has a house very appraised in remap´s, they do a file for the taste of customer and they have a great Know How in this area. Now they are responsible for the files in a US competition (http://www.chilipepperracing.org/). Do you know this competition, find that this Portuguese company is good to be present in this test?

If I go to Interccoler + Trottle body, it is not recommendable to do a remap to take off left better of the Hardware alterations?

So many questions... if to be able to help me I am thankful

Best Regards

 

As far as throttle body is concerned, your fuel milage should not go down at all, you have to understand the larger throttle body doesn't put more fuel into the engine it allows more air to flow thru, and according to the people that I spoke to the Dinan is actually matched better in size and there for is also creating less turbulance and a more direct flow of air. As far as problems, I've not had a one, it's been 6,000 mile plus since the change, but that being said, that is also the reason I went Dinan as apposed to some of the other options out there, just for there reputation with BMW alone.

 

I've got an '06 JCW and have been reading this thread with a lot of interest. With 10k miles on it, I'm used to the power it makes...and I want more. Is there a list of JCW-specific mods people have done? From the sound of it, header, throttle body, flap mod and ecu remap are the basics which should add a little power and a lot of response.

What if I want more? I know it's asking a lot, but what does it take to get to 250whp? 300? :D

if you are looking for a great intercooler... try out a wate to air! I put on my call with a custom dyno tune to 8k rpms and netted about 26hp. All the while the car runs smoother and cooler!

I got mine from MINI Madness. Its doen't even take that much time to install.

Many people don't talk about the water to airs on this board, but i have found a huge advanted running that intercooler!

Best of luck to ya!

There is a lot of information on these forums pertaining to these mods. One quick and easy mod that would give you a noticable increase in performance and handleing is a lighter set of wheels and tires. As far as engine mods a good place to start is with a good header. Different brands will give you different results. I.E. more lower and mid range torque from some, more top end performance from others. You can probably expect approxamately 8 ft/lbs of torque and 8 whp from the right set of headers. This would vary depending on your mods and how well the header matches the ports on your head. After that a good head would probably give you the most bang for the $. There are a lot of them out there, some really good and some not as good. Beware of the sales pitch's, find a good reputable dealer that will work with you on your goal and your mods present and future. It is a good idea to have a plan as to what you are trying to achieve. This would possibly get you to the 190/200 whp mark with a good tune +/-. There are a lot of numbers thrown around here from different dyno's and you should take them with a grain of salt. It is very easy to get different numbers from different setups. Also dyno numbers really don't relate well to how the car is going to feel on the road. A true 200 whp MINI is a very strong car and lots of them do not make the 200whp figure with the mods listed. To get to 250 whp with just a super charger is indead a very special car with all the bells and whistles and lots of good blue printing and matched mods with a very expensive tune. The only way it seems feasable within reason is to go with a turbo or twincharge. There are kits out there that can accomplish this from some reputable dealers. In the end it's all what you want your car to be and how much $ you are willing to part with.
I hope that helps, Steve

 

I agree, I just got a new T-shirt that sums it up for me. On the front is the JCW logo, on the back it says ENDORPHINE MACHINE

 

Ours goes like stink too I still want more stink thou So JCW injectors ,a big thin flat intercooler and some kind of ECU,probably JCW ,a dealer burn because thats three hours away versus going to the east or west coast. There are no tuners in the midwest

 

With all of theese Mod's you can probably expect 230+ bhp but remember thats bhp most of the claims out there including Mini are in bhp not whp, with the overall weight to hp ratio of the mini a bump of 5 to 10 hp is good and feels noticably different behind the wheel. As far as whp, you drive a JCW, you know how strong it is, if you figure your probably getting 170 to 180 whp as is (when you figure in drivetrain loss), all of the above mod's should get you near to a true 200+ whp. For example, do one of the above Mod's such as Throttle Body first, (remember with Throttle Body your only talking 3-4 bhp extra) when you feel the difference that just that little bit makes in actual driving experience, you'll be able to get an Idea of how much a true 200whp really is , and will get you to appreciate the guy's like tuls, and others that are making upwards of 300-400 whp with thier cars :impatient and remember not to loose perspective your doing all of this with a 1.6!
