The Cooper S uses the same getrag 7 gear DCT if i'm not wrong
Tuning a 3 cylinder Cooper ??

EDIT: Oh, I see you were responding to a question about whether a tuned 3-cylinder would be OK with the DCT. I thought you were commenting about a Stage 1 remap on the Cooper S.
It does, but the 7DCT300 is only rated to 300 Nm, so I don't know if I'd chance it beyond factory Cooper S power levels.

Hi folks,
i am writing to better understand the b38 engine. I would like to know the true potential under a stage 3, like the fiesta mk8 that with his 1.5liter can reach 300bhp under stage 3,
i want to know the safty lign for our engine.
From what i have seen, only one preparetor (jmtc performance) have realized a Stage3 with a turbo swap, the result are quite amazing:
262 hp at the crackshaft (234rhp) and 330nm/191 ftlb of torque!
All this result was reached without opening/forging the engine, and currently the mini still running fine also after 30.000 km.
What i want to know is the safty power limit of this engine before it melt on a dyno run... there is someone that have get this powers ?

I think Ford seem to be turning out engines with a relatively higher state of tune than many other manufacturers but I am not sure they are reliable. Their 1lt Ecoboost engine can be bought with an output of up to 125 hp and its great engine but the internet is littered with stories of their unreliability. In this respect, BMW are being more cautious with their power outputs and I am sure these 3 cylinder units can give more but that usually comes at a cost.

This is the dyno run of Mini with 1.5 liter
Stage3, the power it’s on rear wheels!
it’s impressive!
but what is the limit cv/liter for remain in safe?

here the original description below the picture:
"Stock power for the 3cly 1.5L is 134bhp and 210tq at the crank (dyno not shown)
Run 2: 234whp (262bhp) and 243tq, at the wheel with JMTC tuning for ES turbocharger
Run 1: 167whp and 191wtq, JMTC Tuning for the OEM turbo (with the ES turbo installed) Upgrades for all runs JMTC ES turbocharger, 3" exhaust, and high flow air filter, all other components were OEM. The ES turbo with the upgrades added 130hp over the stock power of 134bhp "
No idea what the limit is on a 3cyl 1.5L but Peugeot 308GTi 1.6L 4cyl was running stock at 270bhp on 95Ron fuel.
I owned one for a couple of years and the only issue in that time was a speaker shorting out the amp on the head unit and getting it to accept map upgrades for the Nav

I just installed a JB+ on my f56 1.5t and it pulls like a banshee, only other “performance” mod is a muffler delete. Def not a stage 3 but thought I’d add in to the thread.

Hi CanadianBloke, please tell me more about your tune up.😄
Currently on my 116i 2019(B38 Engine), i'm running with a stage2 (Sport air filter- Inter cooler Wagner clone - Down pipe 200 cells - I8 spark plugs) and a map specific for stage 2.
The output power reported from the tuner it's 190cv and 290nm, but for my sensation is less than declared... around 180cv.
Starting from this winter the upgrade of oem turbo will be complete, but here in Italy it's difficult find a serious tuner for this engine, every time i ask for a stage3 on this engine the answer it's always the same:
"we don't know how much this engine can reach without problem"
Anyway, i think the best way is load the original file before install the upgraded turbo, starting directly from stage2 map can be dangerous because, from what i understood the torque limit it's 320 nm and can be easily overtake!
Some advice?
Can i ask you the dyno run of your car?
Thank You!

Hi mate, it sounds like you've gone way beyond what I've already done. I was looking for some simple power boosts and so far I've accomplished that and super happy with the performance. I have not tested the car but I'm guessing it's making around 170hp (original 136hp).
Here's my simple mods list:
- JB+ tuning module
- Muffler delete
- Sports air filter
- Lightweight Sparco wheels
- Sticky tires, Firehawk Indy 500
- Self done chrome delete with plasti dip
Possible future mods If I don't upgrade to Cooper S or JCW:
- Upgraded intercooler
- Larger brakes
- Full ECU tune
- Sparkplugs
- Rear sway bar
- Spoiler

I agree-it's a great sounding engine.I love triples-still wish I'd not sold my Triumph Daytona but it was so uncomfy-Yam Tracer 900 might be an option!

Plenty of tuning potential with the B38, some forged part and a turbo upgrade can see 250hp or more.. 😈
I drive a modified 1.5L and have looked into intakes and exhausts. The OEM air box should be the same up to the downpipe. JCW models get a larger intercooler, but the airbox to the MAF sensor should be the same. In the aftermarket scene, most Cold Air Intakes or cone filter set ups should work. Stay away from brands like Eventuri, however, or you'll end up having to install a hood scoop
As far as exhausts, most will not work because of the dual exit on most S models. I suppose if you changed the rear bumper, you could maybe retrofit, but not sure. I have a Quicksilver Exhaust System from the UK on mine. Sounds fantastic IMO and really brings out the 3-cyl. character. I might be one of the only F56 1.5L with that system in the states, though. They're a bit difficult to get around here due to having to import.
May I ask which sparco wheels you went for and how much weight you saved? thinking about Oz racing HLT but they are too expensive.
wow that's impressive, may i ask how much all that that costed you more or less if you wish to share? that's faster than a S now?My wife's 3 cylinder 1.5 is running over 210bhp. And it's a fantastic ride
2017 Mini Cooper Clubman - out of warranty due to some minor mods we carried out. The engine went boom due to an OEM spark plug which failed and melted the piston which in turn damaged the cylinder and melted the cat. Once we had ascertained that BMW would not help out we took the (big) decision to rebuild, strengthen and tune.
So..... in no particular order: BMW i8 pistons and rods; stage 2 Superchips remap; Forge intercooler; Eventuri induction kit (with new Cooper S bonnet to enable scoop RAM air); Miltek decat pipe; Remus cat back exhaust (Cooper S twin exit.... so now running Cooper S rear bumper); JCW big brake kit (with grooved and drilled discs); Forge brace kit; KW coil over kit (70mm drop); 20mm wheel spacers all round; JCW gearbox (2ltr spec); strengthened clutch; lightened flywheel; Quaife LSD; Dunlop Sport Maxx tyres.
I think there is maybe more.... but it's been a quick journey and I tend to forget some of the things we have done... sometimes things worked and sometimes things didn't and we had to try again. Biggest headache was the LSD.... which didn't fit the original gearbox and led to head scratching with everybody at Quaife and the tuner until we realised small differences in the fitting kit tolerances meant it would never fit (I was quoted for Quaife to build me a bespoke LSD but it was going to cost over £5K and they needed the gearbox for a few months ? )
We believe that we have trail-blazed with this car - doing things which haven't really been done elasewhere. Possibly more power to come from a different turbo....but for now it's just a really fun chuckable car to drive.
Ask away - chances are we have tried and failed or are enjoying the fruits of our labour ?

Hi all,
Can anyone recommend a good 1.5T tune that can be done remote or via handheld.
Should be for a 03/2018 Mini Clubman ONE (1.5T).
Many thanks,
Tim
Has anyone tested this one:
+37BHP / +81NM for the Cooper.
For ONE should be the same map. They offer a softer tune for the ONE as well.
Like the idea of that Powergate handheld.

No Bluefin unit available
No Bluefin? No problem! Get a remap from our parent company, Superchips.
