S,Pimp seem to be very sure about the HP numbers. A 5.5 liters engine, doesnt that mean they have to rebuild the engine completly? If so, that must be very expensive so is it really worth it?

What about Torque, is 580nm possible, even 600 nm?

Raised redline to say 8400 rpm and the new DCT, do you think the M5 will get it?
