Well down to 110 is still 80+% of the max (which was 134). Looking at that dyno, the current S2000 has its torque peak at 6700rpm (instead of the spec'd 7500) and it's max HP comes at 8600rpm (instead of the spec'd 8300). Using those dyno numbers, there is a 1900rpm difference between max torque and HP in the current model -- which is more than the 1200 difference spec'd in the new model!

No combat intended but it does you no good to overrev the engine. Your upshifts, depending on what kind of driving, let's say for max acceleration, would occur somewhere between max torque and max hp. Whatever gives you the most linear acceleration.
Does anyone know the vtec activation revs on the S2k? I thought they were around 5500.
What if your accelerating uphill? Don't you want max torque shift-to-shift?
If you going for top speed- then max out your hp peak- again at 8300. I see no practical advantage to taking it to the redline of 9k. Someone educate me if I am wrong.

Do you guys have the foggiest clue what you are talking about? If your engine revs to 9000 rpms it will NEVER be faster to shift at 8000. Not unless there was a dramatic drop in power...and I mean extremely dramatic. S2000s are still making very useful power at 9000 rpms. Unlike a lot of owners on this board, I bought my S2000 to drive. It's a toy and I drive it like one. I have 72,000 very hard miles on mine. I use every bit of the tach at least once a day and I have more track miles on my car than some of you have total miles. I don't burn any oil and I consistantly outrun other S2000s. On top of that, I made 208 rwhp. Thats a very above average number and I made that at over 60,000 miles. This motor can take it. Revving it to 9000 rpms isn't tearing up my precious little motor. In fact, after having torn mine apart once and seeing how it's built....If I had the engine management to allow it, I'd feel 100% comfortable revving to 9500, maybe even more. I rev the LS/VTEC in my crx to 9200 rpms and it has a terrible rod ratio in comparison to an S2000.

Even though I originally posted something about the new engine's wider band between peak HP and torque myself, it's probably not wise to read too much into that number.

[B]After all, the 2.0 was making, IIRC, 151lbs-ft of trq at 8300rpm.
Here is a good read:

Here is a good quote, "It is better to make torque at high rpm than at low rpm, because you can take advantage of *gearing*."
