burning smell after hard acceleration

["Solomon Ngan" <sngan@alpha.netaccess.on.ca>]

Hi everyone,
Finally weather was so good this afternoon, I gave my 90q20v
a workout.   At stand still, I dropped the clutch around 4,500 to 
5,000 rpm.  And I continued pushing to 6,500 rpm between 
up shifting to 2nd and 3rd.
The 90q responded nicely with a quite a strong pull.
But there is a "burning" smell right after that.  I repeated that a 
few times and everytime such a smell was there again.
Any idea what that smell may be ?
Possibly :  1. clutch wear ,  2. tire,  3.  motor oil, I use 
synthetic oil.  ??? 
Is there any cause for concern ?
Other than the smell, the car ran fine.  I was having fun with it.
