I've searched here and google and haven't found one as all the dyno sheets have mods....I really want to know what the powerband is shapped like and the RPM's it peaks at.

There's a button on the opposite side of the screen as the new thread button. Its called "search". Thats the one you're after.

This is the dyno graph from the 1990 SAE paper by Mazda on the S5. This is what the engines did new.

Notice you can see where the VDI valve opens on the NA.

^ do you have that SAE paper anywhere that we could download it?

The site I got it from no longer has it. I can e-mail it to someone if they want to host it. It's a 12.2MB PDF. It covers all the improvements made to the S5 engines like VDI, independent twin-scroll turbo, electronic boost control, EFI improvements, and electronic OMP.
