Brown & Gammons build racing XPEG engines that are reputed to put out
about 145 bhp. These use a flywheel that can best be described as
resembling a bicycle chain-ring - there's a periphery that supports a
ring gear, a flat surface for the clutch to attach to and bite on, and
not much else! I'm not sure how much (or, should I say, how little) it
weighs but it isn't very much. My experience of one of these in an engine
is limited to driving the ex-Ken Miles R1 a few years ago, after it had
been fitted with a number of B & G's trick bits. It certainly revved
freely (close to 8,000 rpm) and crisply and exhibited no lack of
tractability that could not be attributed to the racing cam.

Lawrie -
Indeed these flywheels help things go well!
The important thing to stress here is that these are MADE as
light flywheels using specific high quality aluminium and steel
components and are not LIGHTENED STANDARD flywheels,
If you lightened a standard XPAG flywheel to this extent it would
almost certainly disintegrate at the revs the T racers use.
