The problem with the S55 is the 3.0L. If the car were to have a 3.2L or 3.4L engine then it'll be a bit harder to compare the S55 with the N54, but since both are the same exact CR, bore and stroke then the only difference might be the turbos, cooling, and potentially different fueling system. An N54 struggles to break 400whp on pump gas without meth. But again, this is not an N54.

If the S55 runs 12-14psi stock (18.9psi is MAX), and it's rated at 425hp (431ps), and we all know BMW is underrating this engine, then you are looking at least 370-390whp STOCK. That's STOCK! Perhaps we are underestimating the size of the stock turbo or the tuning potential of this car.

Now we go to the "limited" tuning potential predicted by many of you. At 370whp-390whp stock, that is already running close to a FBO N54 with a full warranty at your disposal and stock drive-ability and reliability. That right there should be plenty enough for most of us. Now, BMW will NEVER produce an engine where it's working at its full potential just because of reliability issues, warranty and even potential lawsuits. A FBO S55 should be over 450whp easily. Spent the $10k you'd have spent on an S65 SC on an pair of upgraded turbos and you`ll be over 550whp without a doubt.

So relax. The fact that you don't see the potential doesn't mean it is not there.
