I don't know about that, I'm sure someone could shed some light on the
subject. But aluminum wasn't an option since Revington TR was the ONLY place
that had one to fit a long crank. Figure $525 for the part and another $90 for
shipping (this is just a guess), so NO WAY.
The man who did it has been doing MG flywheels for a while, and I hate to
say it Vega ones too. So I assume it is strong enough. There is still plenty
of material left on the flywheel. I really didn't want him to go lighter.
I've heard of the aluminum ones "walking", and think this refers to the
crank bolts elongating. Not sure of the truth to this.

For some reason I have always thought that, pound for pound, aluminum is
stronger than steel. The lightest aluminum flywheels on the market are 11
pounds. With only 14 pounds of steel is your flywheel strong enough for the
job?

Subject: Flywheel lightening, before and after
6 Pack,
I just wanted to fill a few people in on what was done to my flywheel.
I've
been considering lightening the flywheel for a while and was going back and
forth on it. Since purchasing a new one wasn't an option, for a long crank
TR6 (TR250 and '69 TR6). The only place that made one was Revington TR and
at
last check it was $525.00 plus extremely high freight, ouch! Fidanza makes
one
for only the later TR6 for $310 (http://www.tsimportedautomotive.com/).
So I checked around into machining it down, prices ranged from $150-300 .
150 wasn't bad, until John Shewmake (fellow six packer) told me of Race
Engine Designs, 770 Chickamauga Ave, Rossville GA. 30741 (1-706-866-3000).
The
price paid for the lightening and balance was $90.00, plus another $25.00 to
resurface. The before weight was 22 lbs w/ ring gear and 14lbs after. Sorry
I
can't report on how well it does at this time, but John said it was the best
improvement for the money.
My TR isn't set up for any high speed racing, but I think it needs to be
mentioned that it is possible to have hairline cracks in the flywheel, not
likely, but possible. So be warned, my will be magna-fluxed just in case.
If interested check out the photos.
