honestly not much else is needed at the end of the day.
The runs were on the board about 20 years ago when a Group A Touring Car Ford Sierra RS500 Cosworth 2.0lt could do the Bathurst 1000km race with 680bhp! on a T3/T4 @ 36psi boost (H trim compressor wheel), and only 7000rpm.
We today with our 13B rotaries have another .616lt capacity and a more modern T04Z (full turbine section) and similar boost and you can very easily make 700bhp on this turbo if you know what you are doing and are not a soft cock with boost pressure
