The Natural Philosopher (The Natural Philosopher ) gurgled happily,
sounding much like they were saying:

Now obviously these are all at the quick end of the market. But
they're there, easy to get hold of, and reliable. Which sort of makes
your contention that 70 bhp/litre is rare a bit wrong.

Panhard were putting out 60bhp from 850cc in the '60s - with two valves
per pot, air-cooling, carbs and pushrods.

Its easer with little engines, cos the revs acan go higher. Its even
easier wit 2-strokes, cos they get two bangs to a 4-strokes one..

Umm, that Panhard lump put out peak power at 5,750rpm - and it's a four-
stroke. Two-smokes don't tend to have pushrods...
