there is a subtle "clunk" sound when the clutch plates of the LSD are engaged. you have to specifically listen (look-for) it.

for example, if you have a piggy-back or flash your ECU with a higher boost, your car will easily loose traction even in a straight line when changing gears from 1->2, or 2->3 (sometimes 3->4 if you are pushing hard). or if you push hard during turn-in or accelerating hard out of the corner (in 2nd gear), you will also hear the clutch plates engaging.

i drive a MT, so I know exactly when the gears are changed (the LSD sound comes just after that). but if you drive an AT, your LSD should perform the same way, but you have to look-for that sound at the same time you know the AT changed gear.

all clutch-type LSDs have that sound, even OS Gilken (http://www.osgiken.net/faqs.html), a competitor of Drexler.
