Power curve
This is the power curve wich fits Stan's torque curve.
I think Stan's is reliable 'cos the values I obtained for maximum power fits mazda's really well.

) in newton-metres or something... his post is a dozen down the list from the top by now...

Torque curve does really come from an official mazda press release. It contains all the latest pics of the rx-8 I had seen, all the information that spanish media had published and some more.
The swiss mazda press site is free access (I tried others but required a login).
I am not sure 100% the curve belongs to the final sale version of the RX-8 but a 250 hp test engine can't be very different.

I used excel to calculate the power and build the graph (power=torque x speed).
The values like "173 Nm" are taken aproximately from mazda´s curve above, it coul be maybe 172 or 174 but it does not matter a lot.
The scale is 10 Nm each line (90% torque at 3250=198). This makes an unusually flat curve (¿?) but it comes from a mazda´s site and 220Nm at 7500 rpm is mazda's value.
