Funny Smell Under Hard Acceleration

[t1m350]

Hi,

 

I’ve recently bought a 350Z, it’s got 100,000 miles, seems to drive fine, pulls fine, engine feels and sounds fine. But under reasonably hard acceleration, it makes a funny smell... sort of an ‘off’ smell - hard to describe, but smells almost like halfway between rotting and burning. Any ideas what this could be? 

 

Thanks.

Other people seem to have put this down to the cats being incredibly hot and burning off residue left on the exhaust.

I picked up my Z a couple of weeks ago and have noticed something similar when I slow down after flooring it - I don't think it's a problem.

I have the same I think it’s clutch .. as the plates rub together

Most likely to be clutch burn, do you know / have record of if and when clutch was replaced, 100k mileage would be a good indicator it's on its way out if not previously done

There’s no record of it being changed, I’m planning on getting it replaced very soon though, so hopefully that’ll cure it.

Thanks guys.
