Amazingly the new BMW M5 V8 engine reverses the normal flow of intake charge and exhaust flow. The exhaust valves send the exiting gases out into the middle of the V in the block and straight into the twin turbos also mounted in the V. (hard to imagine how they deal with the heat from the turbos there)
