The NSX has decent stock lsd, as I recall, the car had only about 340bhp from low boost turbo, and it was a daily driver with everything intact, so it must have been quite heavy. I definitely felt the rear outside loses traction first when I floor it, not a weak diff in my book, maybe because the car has low miles and had the diff oil replaced.

1991-1994 NSX’s like our project NSX have conventional clutch-type limited slips, which in the case of the stock NSX is pretty light. This is fine for the output of the stock engine with soft stock suspension and small tires but as you increase the power and grip, the locking ability is not strong enough and inside wheel spin rears its ugly head again. While the stock LSD unit can be preloaded to be ‘tighter’ and more aggressive, it still has shortcomings in locking ability, design, and tune-ability. For our turbocharged engine, and planned bigger and stickier tires, this was not going to cut it.
Case & point
If the NSX Diff was too tight you would have diff induced understeer on a NSX with Track Tires and only 340hp..
Track tires should hold a heck of a lot more power then the stock diff can handle, track tires and more power Id go for a tighter diff than the stock one..... Just like [url]www.motoiq.com[/url] on their Project-NSX
Honestly sounds like the tires were not up to temp or just about done, or they were simply not track tires but regular garbage not even up to par with the stock tires possibly a cheaper alternative that is so often the case with NSX...
However most racers will say that throttle over steer is easily fixed with better throttle control. 340hp NSX on Track Tires, not likely a question of throttle control, sounds like tire issues, cold, old or Chepo Budget OEM Replacements....
BUT That is an issue doing a quick run with somebody else car, sometimes the car is not at its best when testing, tires not in ideal condition etc...
