Higher revving, narrower powerband, not more. That is the difference between "torque" and "HP" motors, see F1 and motorcycles. Shorter runners at high rpm, not longer. Turbos muffle engine sound. The cams in this range are hotly debated, and most folks come back to AP1.

Does anyone recall an article a few years back entitled "Heaven at 13,000 RPMS" regarding an S2000 that did over 12k?

Never heard about it but I'm very interested! SOMEONE FIND IT!

and my last comment about destroking to a 1.8 was a joke for those who didn't catch on. Last thing we need is to lose more torque.

Piston moving faster than the flame front? Uh, I don't think so. How did the piston get going that fast? How does Honda, Toyota, etc. get racing engines to 18,000+ RPM? Limitations on piston accelerations are place on them by rod strength, pin and boss strength, etc. Big parts acceleration problems. Takes big $ to exceed factory engineered limitations, all else being equal.
