i think i saw it in a magazine, sports car, or something like that, the engine was set up so that the exhuasts got put right back into the engine, all of it, instead of EGR, it had hydrualics lifing the head putting the valves at different angles and heights (that really makes you wonder what type of headgasket eh? ?haha), had electronic automatic cam timing, all that bunch.

I think the engine went through about 5000 cycles before the exhaust went out teh tail pipe so that the thing had 0 HP after all the technology had been put on!
