In addition, I think someone above mentioned at 22 PSI this engine would put down 700, I tend to think it would be a lot more if it was possible?
We need to be grateful the engine doesn't take 22psi to make horsepower. It would leave virtually no extra HP on the table for the tuners. The fact that it is valvetronic might be a limiting factor on tuning anyways. Probably one of BMW intentions. Secondly there are hardly any N54s that will run 18psi on pump gas. None on 22psi. So assuming the new M5 needs to run on pump gas..then not likely it would come with a 20psi stock tune.
