I did this about a year ago on my friend's sister's gs-t with a bov. It sounds a lot more realistic if you have a narrow pipe that the air has to go through and a bike intertube for a coupler. The innertube acts as a baloon, and the narrow tube limits air, so you get a real QUAAAAAAACK. Awesome.
I was replacing a ps/alt belt (an alt bolt came loose and shredded the belt, stupid dsm's) and left the call on. About an hour later she calls me and asks "Is there a chicken trapped under my hood?" Ahhh too funny.
