Yeah, those output figures aren't really possible for a non-boosted engine.

If some insider was messing with a writer and said the BMEP of the engine is 210 psi, and the writer doesn't fully understand how it works, then they would end up with those figures.

If it really does produce a BMEP of 210 psi it is still EPIC, especially at 4000 rpm. But in reality the number will taper down at peak hp. If it drops 10% it would keep the 170 lb-ft @ 4000 but the bhp peak would have to move up to 6900 rpm to make 200 bhp. Still pretty good power curve.

If it only dropped 5% it could make 205 bhp @ 6700 rpm. Which would be wicked.

Edit: Or 200 bhp @ 6500 rpm with that 5% drop...

Whatever the case the mag numbers are not possible, but 210 psi at 4000 rpm torque peak would be very nice.

(Also note that BMEP for torque is not attached to rpm, so the 4000 rpm could also be very optimistic. 210 psi BMEP on a 2.0L motor equates to 170 lb-ft, but doesn't tell us where in the rpm range.)
