No more tail bone
It's a Mitsubishi Evo engine fitted with what is essentially 4 Smart Car turbos. It was done by Owen Developments in the UK as a small showcase for what sort of things they could do, although it was never intended to actually power a car IIRC. Worked though. Looks like the photo was taken on their stand at an Autosport International, they usually have it there.
