Blocked turbo

 

[pete]

Its the air going back in against the turbo blades which cause the chattering sound.

 

[Scruff]

Its called wastegate chatter.

 

[varuka]

squirrel mincer

 

[hiwd]

Its air going back through the turbo blades when the throttle is shut. You can get it by removing your dump vavle. Not very good for your turbo though...

 

[Hammie]

Would love to be able to afford to replace turbo's often enough to have this kinda thing........

Sounds Savage......

savage sound

 

[B4 soon]

Actually its the antilag that causes it-that combined with the 2bar boost pressure wrcs run
