Been around for a while. None of the big manufacturers are taking the chance yet, bums. I've heard a rumour that a coupla big engine makers (for semi's) have been looking at these. Given the numbers you see in the big engines, the efficiency upgrades the Coates system provides means big savings.
The nice part about this is that really good tech that makes it well in big trucks, eventually trickles down to the car market. The really slick turbos being produced these days learned reliability tricks from truck turbos.
Pray to the Car Gods that we see these produced for ANY car engine on ANY sort of scale. You can get them, in theory, from Coates Engineering, but they are supposed to cost around $5k - $15k from what I hear.
