Thread: Weird noise under full throttle

Hey so I just got my 05 GTP on 11-2 and had to get inspection done and such and also got a new radiator cap because of a coolant reservoir issue. Love the car but I've noticed that under full throttle after it gets past 4k revs there's this sort of sucking noise coming from behind the dash/DIC area. Sounds like when you suck the last little bit of soda out of a cup with a straw...Any ideas?

Bump... Anyone?
