Howdy all-
cubes=hp is not that tough, lots of corvettes and mopars did that.
hp=cc/10 is hard, but the BMW M3, some Honda VTECs, and perhaps a few others
do it. Old cars like Ferraris and Porsche 911s were close, but that was
before emissions controls.
Formula one cars during the turbo era (until ~1990) could get ~1200 hp out
of 1.5 liter engines. And I think that top fuel dragsters get something like
5000hp out of ~7 liters. Two-stroke gp bikes get ~200 hp out of 500cc.
You just need high revs, good breathing, and lots of gas. I drove a friend's
Honda s2000 with a 2.4L and 240hp. It redlines at 9000rpm, and it really
doesn't feel all that strong until you go past 6000rpm(!!). But honda
engines are bad candidates for swaps, as they rotate the wrong way.
Parenthetically, there is nothing sacrosanct about small displacement
engines. The key is to convert gasoline and oxygen into motive power, and a
small engine doesn't necessarily have an inherent advantage, even in fuel
consumption, other than that the reciprocating masses are lighter and thus
more able to be revved higher. Our obsession with small engines is an
artifact of european tax laws that are concerned with displacement, and
since European cars are the better (VC), we aficionados tend to think that
small engines are better.
