47% more torque is rather dishonest. They just turned the boost pressure up to get that.
A typical NA street engine with 1 cam profile produces something like 75Nm/L at 1500rpm, and around 100Nm/L in the midrange. With a big cam, you can get 120-130Nm/L at high speed, but that's it.
Ideal valve timing can get you maybe around 90Nm/L at low speed rather than 70-80, the same 120-130 at high speed, and maybe 110 in the midrange if the intake runners are tuned to work best there. The torque increase is more like maybe 3-5% peak, and 10-20% in "torque dip" regions. The torque increase over something with multiple cam profiles will be much smaller.
If these are commercialized and have reasonable power consumption that would be a dream come true. More power, more efficiency, less weight.
