I was woundering if my Mini Cooper S 06 automatic transmission would handle RMW's stroker 2.0. Some words on the road here say that the Mini's transmission is the worste, so they think I would have my tranny rebuilt few weeks after doing the engine swap. What do you think guys?

English please?

 

BOOM ! ! !

Tranny won't handle it.

 

Sure?

 

Totally sure.
I have a friend whos got just the header/cam combo that says the car just slides from one gear to the next no real shifting happening
But to be positive Contact RMW and ask what kind of options there are such as putting a 6spd in your car or working out the bugs in the trans.

 

6spd? Do you mean 6 speed manual? My car has the Cooper S CVT 6 speed tiptronic with F1 style steering controls.

 

The MCS 6 speed tiptronic is NOT CVT.....

I have the auto with 15%, RMW cam, RMW header, JanTune. Haven't re-dyno'd since adding cam and header... but probably making 200+whp and 180ish tq now... no problems yet... but that's WAY less torque than you'd get from the stroker...

The Aisin TF-60SN tranny is rated for up to 236 ft/lbs of torque at the crank...the stroker will exceed that... by a fair margin...

 

Thanks Paul. So My plan is to go for an RMW header and cam. That should keep me in the safe side for now.

 

By the way, from my list of mods, how much do you expect I'm making? I have not dyno'd it yet too.

17% pulley
JCW injectors
JCW intake
JCW sparkplugs

and the cam and header are on the way...

Give Jan a call or PM him for his advice.

 

Yeah I'll ask him next time I call placing my order.

 

Really hard to say on MINI automatics... they are VERY funky to dyno because of the way the torque converter works, and lock-up points. You can't get a smooth torque curve like you can on a manual. As well, you have to start the dyno pull at a higher RPM (because otherwise you can't shift into third) and raising the rev limiter doesn't do anything, because the tranny will upshift at 6750ish no matter what. So you "lose" several horsepower at the top end that most people get just by raising the rev limiter.... your car still pulls hard... it just doesn't have as much "theoretical top end"...

Here's my dyno sheet (before the cam and header, which made a TON of butt dyno difference) - sorry for the melted ink...



FWIW, performance mods then included:
15% pulley
JCW injectors
One-ball exhaust
JCW intake w/AMSoil Nanofilter
Alta intake tube (like that does anything haha)
NGK/JCW plugs
RMW Tune

Cars with similar mods and manual tranny were breaking 200whp that same day.

I'm of the opinion that the autos need about one additional power mod to keep up with the manuals... in my case, with a heavy convertible and a fat driver, I need two...

 

Going for the abstract watercolor school of Dyno sheets Blimey?

 

haha

 

Just in case you do not know, this is what Middle East dealers call the steering wheel mounted shifting paddles.

 

hey I steer and shift at the same time with my 2009 MCSa!

 

Yep... it answers the age-old question:
"What happens when the dyno printer uses water soluble ink, and your dyno sheet gets wet on the way home, and your tuner fails to save your dyno plot so you can get a reprint?"

Because I know you've asked yourself that many, many, many times.
