Good find!

To reach 180kph, he'll need to get about 45bhp out of engine.
Certainly possible with big-bore high-compression pistons.
Retard intake-cam. More duration and overlap. Higher lobe-centres.
Still need to do something about restrictive intake-ports.

Must be nice to have dyno right at track so you can go out to test right after changing settings.
Having programmable EFI system makes it so, so much easier.
