Recently I was doing around 70 mph and decided to get on it. @ around 80 I squealed really loud like a belt or something. I have a SBC DD 3600 and that squeaks occasionally when shifting gears for some reason but I hope thats not it. It does it when rpms are kinda high. I know it will be very hard to answer but Im just trying to figure out what it is. The belts don't seem very loose. Kinda like they should feel unless it has to be TIGHT. The clutch was also just put in last year. Thanks for any help.

 

high rpm, what was your boost at? the turbo may be rubbing the housing. hopefully not.....

 

Could be an exhaust leak where the turbo mounts to the manifold Ive had this happen before and it sounded just like a loud squeal.

 

Thanks, I hope thats not it. I was at probably 30 lbs.
