https://www.onpointdyno.com/making-p...dyno-timeline/ <--cams really made the engine shine...
A Stock VQ35 @ 215whp vs 372whp at 3900rpm there are almost no gains, 5200rpm ~70hp – but the peak to peak differences are 157whp
Same displacement, same valves, same oiling system, same drive train. The differences are cams, heads, pistons, rods and external components. <--Cams & ITBs are what is doing the majority of this. Engine's are air pumps and you just need to get as much in and out.
