HI Guys
ONLY a competent machine shop should undertake the operation of removing
mass from a flywheel. If you get it wrong not only will the engine balance
be wrong leading to a lumpy idle and harsh engine, but the thing can fly
apart and cause all sorts of problems in the process. The TR flywheels can
be taken down to around 7.5 pounds if you wish, but this is extreme and
should only be used in race applications. For a street car I would think
that 15 pounds would be a good weight to aim for. Given the mass of the
stock item to remove this amount should really be no big deal for any
performance shop. Ask around as to who the local drag race guys use, as they
have to know where the good shops are!
I hope this helps

Subject: Lightening flywheel - TR3a
I know I read about this somewhere, but once again I can't find it. I
really thought I had printed it out.
Can someone give me your thoughts on this matter? I have a 30 lb flywheel
sitting here; it seems like it could lose a few pounds (5? 7? 10?) without
significant effect on the idling. So my questions are two:
1. How many pounds can I take off and still have a pretty smooth idling
car, and a flywheel that won't fly apart at speed and remove my ankle?
2. From where should the excess be removed?
TIA,
