Hi,
From lurking on triumphs-digest@autox.team.net for a while (I just joined
this group) I got the idea to lighten my flywheel while working on my clutch.
I had read that 18 pounds was a good target, and that about 10 pounds of
metal would need to be removed (wow, that's a lot). However, when I took
my flywheel to the machine shop yesterday it only weighed about 21
pounds. It is from an early TR6 engine (CC29630HE) and shows no signs of
being lightened before. There happened to be a late engine in the shop for
comparison --- it's flywheel weighed about 26 pounds. Does this make
sense? Or was the scale very inaccurate?
In any case, what is a good target weight for an early flywheel for a
street driven car? Kastner's Competition Preparation Manual says
approximately four pounds can be removed, which would be about 17 pounds.
This is assuming that the manual, which was published in 1968, refers to
the early engine.
Whaddayathink?
