I never saw the any results from these tests, only heard them alluded to.
Did I miss it? I'd like to know more about the testing process.

I didn't think there were any real results yet. Last I thought I heard
was Bill was sending some out for testing.

IIRC Bill posted in some thread on Miataforum that the results were
that there was no difference strength wise between them. Hopefully
he'll jump in here soon.

Rods were tested by Carrillo. I was very skeptical about that, as I did not
see Carrillo as a disinterested third party. Had their analysis revealed
that, "Low and behold the rods are weak and need to be replaced with Carrillo
rods," I would have been the first to cry foul. However, since they found the
rods to be same as M1, I have no reason to doubt their integrity.

Bill C. will have to step in here and fill us in on the details of the actual
testing process. I'm assuming stretch test, compression test, shear test,
maybe more.

I sent a variety of m2 and m1 rods off to Carrillo. They did rockwell
testing and "spark" testing, which is supposed to give carbon content. They
said they were all in the same range, though made from different dies. I
would have sworn they were weaker...
I believe rockwell numbers came in around 26-28, believe the carrillos are
low 40s.

I don't know much about rod manufacturing, but having been a senior buyer in
aerospace (Boeing) I know a little about heat treating. Rockwell 26-28 is
pretty low really. As an example I now buy for a manufacturer of
hydro-mechanical pumps. We routinely heat treat our valve plungers to Rc 46
and I'd say they receive a LOT less wear and tear than rods in an engine? Of
course harder isn't always better, if you go too far they can become
brittle. To determine "strength" I'd expect tensile tests...not just carbon
content, IMO. The downside to tensile tests is that is a "destruct" test and
you'd have to find rods willing to make the sacrifice ;)

I was wondering about that myself. Why no tensile tests, Seems to me
that would be the item that you would really be interested in knowing.
