I agree, once again. The engineer and somewhat experienced hand with these old air cooled motors in me got all wrapped around the axle regarding the number he claimed. I hope - and I'm pretty sure at this point - that my anal deconstruction of just why that number is "impossible" did nothing to diminish his enthusiasm for his freshly completed build. He sees something there that I do not, and he is enjoying it tremendously. We've actually kind of made friends, in the end, and he is sending me photos of the entire build, from a rusty '70 T to a down to the bare tub and back restoration. It is a beautiful car, no expense spared.

Yeah, and back to the numbers game, at least here, on this forum. At 330 crankshaft horsepower (15% correction applied from 287 RWHP), we see 122.24 hp/liter, a specific output that closely matches that of the modern 4.0 liter GT3 engine wherein at 500 horsepower from 4.0 liters, we see 125 hp/liter. So, yes, we can see what it takes to get there. Water cooling, four valve heads, direct injection, and I believe about 9,000 rpm. It can be done. Hell, modern, normally aspirated liter bike engines are now exceeding 200 hp/liter - at 14,000+ rpm.

In the end, though, like I said, it just doesn't matter. He's ecstatic about a very cool, freshly completed build. That's all that matters.
