Car & Driver comments on 2004 S2000

For all those who are rev happy. Peak hp on the existing motor is 8300rpm and torque peaks long before that- not at the redline 9k. There's a cliff effect after 8300. You gain nothing except more wear and tear on your precious little engine by taking it to 9k. Is that what you want? Reaching peak hp and torque on this engine a little sooner and for a longer duration is a good thing. I don't care how you slice it. Go talk to an automotive engineer if you need further convincing.

Well there will be the same cliff effect after 7700 rpm with the new engine. So let's compare apples to apples here. Are you saying you won't ever rev your S2200 past 7700 rpm? Because if you do "you gain nothing except more wear and tear on your precious little engine".

So where in the RPM band do you shift for maximum acceleration?

Which is exactly why I am curious where he shifts, since "You gain nothing except more wear and tear on your precious little engine by taking it to 9k."

I don't think you can say at this point if there is any more wear and tear on the older engine shifting at 9000 or the newer stroked out version shifting at 8500. They will both have their own particular stress points related to redline.

how you figure more displacement is good?

Yeah, I haven't studied dyno sheets enough to know whether there is a sharp drop-off of power after the peak, but if there isn't, then it makes sense to hold the gear as long as possible (i.e. to redline) so that after the up-shift, you are as close to the power peak as possible.

If you look on page three there is a dyno test on an S2000.
The torque(pulling power) at 9000 is down to 110.
At redline, all you are doing is making a lot of noise.
