The spiral things are the rotors of the supercharger. It's a sleeve-valve V6 2-stroke, more or less a copy of the Rolls Royce Crecy, which would have been the successor to the Merlin. This is just a scaled-down version. I'm guessing that modern metallurgy and fuelling technology (it's direct injection) would help it all along.
This thing is 800cc and would produce about 250bhp @8000rpm. This would have a bmep of just under 200psi, which isn't much. And without all the friction and pumping losses of a 4-stroke, the amount of heat produced wouldn't be excessive either. It works like this.
It'd just cost about 250,000 euro to make, which is why it won't happen. At least, not this year. The CAD program is Solidworks.
