Exactly. Specially prepared racing engines. I would suspect that a
stock or even mildly warmed-over TR6 engine just might become
shrapnel at those kinds of RPMs. Hyperbole? Perhaps, but not by
much.

Because they're incredibly huge, ugly, sloppy and generally
unappealing cars. No offense to any Cadillac owners out there
just
my opinion!

While in recent years my driving 'style' has become more sedate, that
has more to do with the fact that as a practical matter, I cannot
afford either the money nor the time right now in my life to do much
in the way of tweaking my TR6. Right now I'm faced with an
unexpected gearbox rebuild and as God is my witness, I haven't got
the time to do it. I'll have to make time, though, since we only
have one other car. What's the point? Point is, I drive the TR6 in
a way, hopefully, that will minimize unexpected repairs. This means
I have to control my lust for lateral g's.
I have, in the past, hurled that TR6 around corners at speeds that
would have most people bailing out. There are few things that are as
enjoyable as driving at nine or ten tenths on a curvy road.
But the contention that TR's by definition were meant to be driven at
the red-line all the time is very ill-informed, no offense to Phil
Smith who was merely passing on someone else's comment. Triumphs
were meant, quite literally, to operate anywhere between idle and
whatever the red-line happens to be on your model.
Much of this issue depends upon how the engine in question has been
prepared (IF it has been prepared) and how it is tuned. If you've
made modifications to push that red-line up, I congratulate you. I
have too, with my TR6
but the particular cam I have dictates that it
is quite useless, as a practical matter, to rev it much higher than
4000 rpm. Not because it will come apart at 4000, but rather because
it's passed it's power peak and once there, if you truly want to go
faster, you'd be well advised to shift up!
