Flutter Then High Pitch Sound

[EVL032]

just wondering if anyone know if this is anything to worry about, i got a high flowed turbo and when i hit boost the turbo squeals but still pulls 15psi nicely then with my metal in the wastegate no blow off valve, i make my flutter sound and then it makes this new high pitched squealing sound like when u let the air out of a balloon slowly,it does this 90% of the time does anyone know what this sound is i have checked all the piping for leaks but i can not find any???

thankyou

Sounds like the bearings are stuffed

i had that enzact problem and it was a silicone joiner,

could be the exhaust gaskets, causing the squealing, thats wat was wrong with mine....

mmmmhh interesting i wonder which it is. i doubt the bearings, cause it still boosts sweet. now how to locate the proplem??

it would still 'boost sweet' with slightly worn bearings.. how long it boosts sweet is another question.
