Drivetrain The Always Up-to-Date Thread on Tuning 2011+ (N18) MINIs
#2101
Fair enough but its hard to fault folks for wanting to keep an active thread churning. It's been pretty quiet for the N18 folks until now when it comes to tuning. I understand the excitement. I'm pretty sure Terry can speak for himself.
#2102
Now to see what can be done with Stage 1 to eek more power and still keep reliability.

I don't see any reason the n18 can't handle the same boost. It's just a matter of the tuners taking their time testing to keep things safe as they ramp up.
The JCW/GP are no where near close to maxed out from the factory. The S is not either for that matter.
All of that said I am excited to see tuning options appearing. My 2011 MCS needs some tuning love. It feels slow compared to my last two MINIs.

The n14 and n18 engines are pretty much the same engine. There are a LOT of n14 engines running around at greater than 20psi with the Alta access port. I know of several that run around 23psi. You do need a larger intercooler though. I'm also pretty sure those tunes change a lot more than just boost.

The S and GP2 have 10.5 CR which would also limit max boost more than JCW 10.0 CR.
So I see the GP2 as the 'max' a S can do while keeping reliability, hopefully I'm wrong. Does anyone know max psi on a stock GP2?
The N18 is designed for mpg > power and the fact that it produces more power and mpg than the N14 means it's closer to the limit stock.
The auto is only rated to 235 tq also so that would be the limit a tune could put out without blowing that up.
The N18 runs so damn hot, has no oil/trans coolers, I'm glad the '13 models run cooler H2O in sport mode and JCW full time.

Yesti, were are you getting this 235tq limitation on the autos? Is the surging issuse that guys like NM tuning were having with their autos? If thats were this is coming from then forget it. My N18 auto with a forge intercooler, 2.5in exhaust and a JB set at 18psi running a E85 mix has had zero issuse with thousands of hard miles...Asisan is know for building strong trans, ask my Sc430.

From what I gather the torque limit on the auto box is ~235 lb ft. Not sure what it can run at on a daily basis and still last a decent number of miles (80k?) with regular fluid changes (15k?).
If the JB+ gives you 30 more torques how many are left before the tranny needs to be strengthened?

EDIT:
Here it is http://www.aisin-aw.co.jp/en/product...eup/index.html the MINI uses the TF-60SN the chart is kind of confusing to read but I think it's rated around 400 Nm which is about 300 ft-lbs.

Where is this 235 ft-lbs coming from?, I believe that it is rated in the same range as the Ford model (AFW-21) which is 325 ft-lbs. I'm trying to find a source for my info...as soon as I do I'll post it.

"All info taken from post on vwvortex" Pretty much everything you'd want to know about the 6spd auto.
Manufacturer: Aisin
Model: TF60SN
Torque Capacity: 320Nm or 230ft/lbs (limited in 1st gear)<--not sure what that means exactly.
Adaptive: Yes
Other Notables: Claims to be "World's first lightweight, compact and high-performance 6-speed AT suitable for vehicles up to 3 liter class by adopting Lepelletier system geartrain" (from Aisin's website.)
Also, it seems that we share this transmission with the Mini Cooper S crowd.

Dyno run 2011 MCSa
Has anyone been able to do a successful dyne run with a 2011 MCSa. I tried and was unsuccessful due to computer causing down shift 2gears. this was apparently due to the rear wheels not turning at the same speed as the fronts .Im interested in your comments.
Thanks

40 degrees this morning, car felt good, very quick in the cold. wasn't even in sport mode. kinda afraid to go sport mode, lol. terry, do you suspect the dyno numbers would be much improved using 93 octane? (based on your quantification of the amount of knocks using 91 oct). what I'm getting at is I wonder if the temps were freezing outside and on 93 oct, what the engine output would be and if it would be too much for it/aggressive.
