Dimman, I think there's a problem. BMW has variable lift, Porsche has variable lift, THIS DOESN'T. The pictures show just a cam, follower/actuator, and valve. Meanwhile, D4-S is supposed to improve fuel mixing at all speeds. I think what is going on is that this engine is it is rev limited because of insufficient rod length (I calculated 1.55 rod/stroke ratio, considering that the dimensions seem similar to FB20) or something like that, and that power doesn't actually drop off that much. 170ft-lb would be 85ft-lb/L, and the 2GR is 79.4 ft-lb/L. With the same valve setup, I don't see this engine beating the 2GR out in specific torque.
Best case scenario would be this engine is underrated. 197hp is definitely very fishy, hopefully they didn't put a retarded exhaust that chokes the motor like crazy so you can opt to buy their expensive optional exhaust
And I still say they are going to add major revisions to this in a few years, unless there really is nothing that can be done about the motor being too wide to fit more stuff into the heads. I just looked at Valvematic again and I noticed that the cam sits to the side of the adjustable follower, so it actually doesn't take up too much space...if they could make the connecting rods a tiny bit longer, throw in Valvematic, this could easily make close to F20C power with 8000rpms to play with.
