But its torque peak is only 354 lb-ft at a very high 6800 rpm. Separation of only 1900 rpm from peak torque to peak power is not good. Compare it to the smaller, less powerful F430's 4.3 V8 that makes 343 lb-ft at 5250 and 490 bhp at 8500. 3250 rpm separating them. That means a much more flexible, nicer to drive engine. It's not just about peak numbers and Toyota knows this. When they redesigned the 1JZGTE they kept the power level the same but dropped the torque peak rpm from 4800 to 2400 at the same time as increasing the torque peak output by about 12 lb-ft. The only reason I can think of making the V10 so peaky is to replicate an F1 type experience. But it's not something that is actually useful to a good driving car. Every driver, even the super awesome ones, are well served by a good torque curve. 354 lb-ft at 6800 rpm doesn't say that to me.

Lamborghini Gallardo has 376 lb-tq @ 4250~4500rpm (5L, not 5.2L). Is that good enough?
