  3. The item pictured is the Cosworth GMA V12 engine designed for Gordon Murray Automotive.
    This naturally aspirated 3.9-liter V12 engine produces 663 PS (654 horsepower) at a staggering 11,500 rpm.
    It is engineered to be incredibly lightweight, with a total engine weight of just 178 kg (392 lbs).
    The engine features titanium connecting rods and valves, along with gear-driven double overhead camshafts.
    This specific powerplant is utilized in the Gordon Murray Automotive T.50 and T.33 supercars.

  4. About 170 hp per liter.

  5. The bore and stroke of that thing must be about 3” x 2”. The stroke is prob closer to 2.5”. Pneumatic valve lifters to achieve that RPM?

  6. Everything Cosworth is sweet. Had a Pinto race engine, with a Cosworth pent roof 4 valve, used, brandy new too rich for my pay grade, side draft webbers worked the best, 4-2-1 tuned header, no dyno's back then, but what power it made was super nice, screaming midrange, ton of torque out of the corners. Regret very much having to let it go, kids need stuff, but it was really great while I raced it. Learned couple years ago certain Volvo heads easily fit a pinto/Ranger bottom end, and are comporable to those early Cosworth's.
