I'm guessing a minimum of +25hp a long with the torque increase
3.0L engine delivering 414 hp is a remarkable achievement, it's more or less a retrofited version of N54 with electric turbo for low end responsivness (no help on max hp). As we do all the mod we can to N54 only make it 450hp and we dont know if that engine durability can be ensured as a normal stock car.
So i say if you guys are looking at 450 or more, BMW can make it but will just leave the job to aftermarkets for warranty trouble.
