Turbo Use

[Fullback6@aol.com]

Yesterday I let my friend drive my Audi, Big mistake.  He revved the engine 
up to7000 rpm and you could smell the burnt clutch after he drove.  After 
that, when i drove it right after him, the car was accelerating weird and the 
turbo didn't seem to be working. I let the engine sit in neutral for about 7 
minutes after the drive was finished, in order to let the turbo cool down.  
Does anyone know why the turbo acted so sporradically after his driving, and 
how long the turbo should cool down for?
