Question sulfur smell with high revs? (going too fast too quick?)

what's that ugly smell when you flog your car around, bouncing off the rev limiter...

i usually run pretty high grade gas, like 92,93,94 - but even then i get it

any ideas? i know it's probably a dumb question, and has been answered a billion times before, but i don't know a whole lot about internal combustion dynamics...

maybe i'm just flogging it a little too much...
heh, gotta make sure it's broken in :-)

It's the sulfur in the gasoline. Changing brands might help, but I personally don't think so, as I've tried it myself. By the way, all my other cars smell the same way. I even brought the car to the dealer where I got the same answer.

I think its a problem that all subaru's suffer from. It gets worse if you've got a straight thru muffler...

I read a tech article a while back about the sulfur smell that plagues many cars at high RPMs.

That sulfur smell is probably a byproduct of the catalytic converters. During high-revving, some gas is not burned completely, and exits through the exhaust. As this "dirty" exhaust passes through the cat converter, a chemical reaction occurs and sulfur smell is produced. It's supposed to be completely normal and safe.
