Data point of interest...

I have personally sheared an outer 100mm type cv joint at the starting line
at a drag strip. Waterfest 2004 as a matter of fact, about 500 people watched
me go - nowhere - after dropping the hammer.  It sheared right where the CV
joint ends and the splined shaft begins.  It's a pretty cool hunk of 
metal that I
keep around.  Car was the '04 GRM race car, making greater then 160hp based
on 1/4 ET and trap (probably closer to 180hp).  Drag radials.  Cheap limited
slip, courtasy of Phatom Grip and Dan Bubb.  Anson helped me swap out the
axles at the strip.  Here's a fun photo: http://cyco.ataxxia.com/sheared.jpg

later.
