"Clicking" sound on stock twins?

370 Views 2 Replies 1 Participant Last post by  soarer 300
When the turbos slowly or quickly spool up, the car makes a consistent tapping sound--its not detonating, its not missing, and it (the car) actually is just as quick as when it doesn't do it at WOT. Sometimes the car does this and other times it doesn't...

And, it does it when the car is cold. What could this be? I wouldn't guess it'd be a loose shaft or anything along that nature...

Could this even be a popping relay?

Any help is appreciated!

I think I may have answered my own question. The car has a Profec B on it and I just read something about the unit doing what's described here...
