Lets play, What's That Smell!?
 

Hi

There is a funny scent when I accelerate aggressively in my 07 supercharged GT.

I only smell it when I left off the gas it seems and it only lasts a few seconds. Its very similar to smelling the hot end of a hairdryer or the smell when your furnace kicks in for the first time in early fall.

I'd hope its nothing to worry about but I figured I'd ask here to be certain.

And dont ask how I know what the hot end of a hair dryer smells

Likely smelling some trace of carbon that gets burnt and blown out the exhaust during heavy acceleration.
