Where the torque and HP cross over on the dyno chart isn't a bad place to shift up @ WOT. Especially if the shift point leaves you above boost threshold, or otherwise in a good place in the torque band. Very little point holding RPM past peak HP. On stock motors without "hot" cams, both usually happen well before redline.
That said my motor is built for mid-range throttle response/torque. Although with Pauter rods, ARP bolts, stiffer valve springs etc
So why do I still take it to 7000 from time-to-time, even though I know perfectly well that with SC cams, HP falls off a cliff after 5500 RPM?
1) To dodge a 2->3 shift, followed 50 ft later by a 3-2> shift. Those who've driven PIR will know immediately which pair of corners I'm referring to... Yes, taller 2nd is the correct answer
2) Because the noise it makes @ 7000 RPM with the wastegate open (and especially in a tunnel), makes all the hairs on my arms stand up, and I can't stop grinning. It's. Freakin'. Awesome...
Word says that 964 cams make their power over 4000 RPM (~1000 RPM higher than SC) and the fat lady is singing by 6100 RPM.
Personally, I think SC cams are perfect for >90% of the driving I do. Boost control means I don't exactly feel short-changed at the top, either.
