Does anyone knows what the maximum torque is that the auto box will take after tuning
Is it exactly the same box as the one in the Audi TT and the VW Beetle ?
I would like to perform a 275 Hp conversion on my MCSa !
Perhaps adding an extra transmission oil cooler would help ?

Don't know if it's the same as those other cars, but I've heard that it's a good transmission that can take some increases in power. Now, 275 hp is hard to get out of the MINI, but if you mean 275 brake hp, that will be less hp at the wheels (due to driveline losses), so that could be maybe 225 or more at the wheels (?). I'm sure the auto transmission can take over 200 brake hp as the JCW will have that, which will be offered for the MCSA. So, the transmission can handle a lot. However, it may all depend on how you will drive it. With 275 brake hp out of the MINI, if you drive it easy I think it will be ok for the most part. However, if you're going to go drag racing, it may (probably will eventually) be a problem, and in the least it will not last as long as an un-modded car. I've heard that auto transmissions last much longer when driven with freeway miles as opposed to around town miles where you go through the gears -- and this makes sense. But auto trannys don't last forever anyway, even in un-modded cars. :)

OK but there should be a way to find out the max torque from the maker of the transmission : Aisin AWTF 61SN
I searched the wab and found nothing !
My dealer says that 245 Nm is safe (JCW kit) but I would like much more
