The new MINI JCW hardtop is a terribly fun car to drive, both on and off the track. However, for some people the 231 horsepower it comes with aren’t enough to raise their adrenaline. To solve that problem the guys from BR-Performance have something interesting to share with the MINI community.

In a recent video published on their Youtube channel, they claim that their Stage 2 kit for the JCW model can take the power output of the 2-liter 4-cylinder engine up from the stock 231 HP to no less than 300 HP. The torque figure also goes up from 320 Nm (236 lb-ft) to 420 Nm (310 lb-ft). The Stage 2 upgrade comes with a new ECU map but also with a new carbon fiber air intake, a new exhaust system and an intercooler to keep everything in check.



The end result is indeed quite good looking and sounds like a machine gun at times. For the future, we’d also like to see the acceleration times from the upgraded model, that’s if you can keep 300 HP in check on the front axle.

In case you’re worried that the brakes are not replaced as well, fret not. The stock brakes have been created from the get-go to handle more than what the stock JCW can do. A source close to the brand told us that the whole car was developed around the front brakes that were seemingly the weak link in the previous iteration of the John Cooper Works hardtop. During our testing we noticed that brake fade never occurred, even though we did push the car to the absolute limit more than once.

I receive a video is not available message. I went to the site with it and receive the same message there. Sort of a bummer. If this is true it might well be the best of both worlds and challenge the GP with a dual purpose funmobile!

How do you manage torque steer especially in lower gears? I’m running a MCS on Stage 1 with around 230 hp and 340Nm and torque steer is quite strong even in Mid Mode.

Install an ATB diff such as the Quaife or Wavetrac, or in the case of the automatic, use less throttle until you are in a higher gear.

Tbh, I've seen F56 Cooper S's do +400 hp with a manual so 300 hp isn't that big of a deal. Mine has 306 hp and 425 nm (automatic 2014-2019) with ECU tune, Milltek De-cat downpipe, Remus V2 exhaust, Eventuri Intake & Forge High Flow Intake Hardpipe.

450 ft-lb? Do you have an auto or a manual? If you have an auto, I'd be surprised if your gearbox survives that amount of torque.

What do you suggest for gear box ( or torque converter ) whatever it’s called for the auto at 450hp - my gears are def struggling being an Auto - I know jack about cars - and it’s the first car I’m having fun modding - just can’t find an answer to this question

Thanks

I have a manual but that’s what I’m thinking how much is too much and can the Manuel handle that kind of power

If you are going to tune it to 450 ft-lb, you should change the clutch to a performance version. Otherwise, it'd probably slip many times. Give a well known MINI-tuner in the UK a call for more details, because I don't really know that much about the manuals.

The cars with +400hp are mostly manuals. Haven't seen an auto doing +330 yet. As you've said, you have 450nm. You should lower this to about 425, because the quoted limit of these automatic gearboxes by the manufacturer is 450nm. You should always keep some margin, otherwise, you're more likely to have a slipping gearbox and it >might< break very soon. But, as I've said above, go to a well known MINI tuner such as Lohen / Mulgari who can probably help you out with this. You'll have to pay more for their services, but they know what they are doing. (unlike many tuners)

The more I read into it no one really does much with the SD I’ve contacted TMC motorsport about the tuning box but they say it’s safe to run on a stock SD

yeah i think ill be contacting either of them this summer - since it looks like several holidays will be cancelled due to the corona virus - ill pump some cash into the JCW - thanks for the advice - like i say i know nothing about cars - can barely change a lightbulb ha

I have been running the TMC motorsport tuning box on my JCW for just over four years now and done approx 30,000 miles,an excellent bit of kit but not well known in the Mini world.
My car is a petrol manual though.
