I'm not claiming our engines are peak performers at about 77hp/liter, but it would make more sense to compare against other 6-cylinder engines in the 3 liter range that have similar redlines. A 370 is in the ballpark at 89hp/liter for example. Clearly higher than our engines but not 160hp/liter. Even an S2000 is only at 120hp/liter and that's considered an extremely high output engine, but again that engine revs to 9k which explains a lot of that.
