Hi guys, I tried to search for some threads on my problem but had no luck. Anyway the other day I was driving and all of a sudden when I hit boost i heard a loud squeeling noise. Since then when I hit just over 2000rpm my car makes a loud squeeling noise, it sounds to me like its coming from the front of the motor, maybe a belt? Theres no smoke and the car still seems to have full power. Does anybody have any idea what it could be? Any help would be very much appreciated.

could be turbos if its on the transition point from vac/boost (listen and watch your boost gauge)
if you think its not turbos, and from front of motor, my car used to squeal if you jabbed the throttle from a stop, and really badly when i put on aircon, crank pully flew off a week later.
the squealing turned out to be the pully part of the balancer had separated from the rubber bonding ring, thus eventually ejecting it from the car.
