engine harshness at high revs

other variations of the vq aren't coarse. this is the only one that's coarse. my vq35de in my maxima is smooth as butter but then again it doesn't produce the amount of powers the vhr does. from what i understand, camshaft-less technology that vvel features is not found in bmws and toyotas. correct me if i'm wrong. vq works. why change it? the design is so good that it's winning awards left and right every single year. no need to start on a new platform.
