Blown Turbo?
Hey guys,
Mods: 2.3L FP Black, E85 and usual bolt ons...
I was just trying to get an opinion of whether my FP Black is shot or not. I installed a new fp 25psi wastegate (in place of stock wastegate) and took the car out to see where I was with the preload (on wastegate boost). I did a third gear pull and was right around 25 psi. I then did another one to double check. As soon as I tried to go into boost, the car started making this high pitch squealing sound and would not build boost. I figured I had a boost leak and did a boost leak check. I then searched the forums and was reading about possibly having a leak at the J pipe gasket. While still investigating the cause of this high pitch squeal, I looked at the blades on the turbo and it looks like there is one that is pretty bent.
I am on speed density and always ran the car with an air filter. When I went to go do the pulls, I was being lazy and decided to run with out any sort of filter for the first time since I was just going down the street to check the boost. I am beginning to wonder if a rock or something bounced up while I was doing the pull bending the blade.
There doesn't seem to be a substantial amount of shaft play but like I said the one blade is definitely bent. I am assuming that this is my problem and what is causing this loud squeal when trying to go into boost. With that said, I guess I was just wondering if my suspicions are right about the blade causing this high pitch squeal and if I am still able to send the turbo back to FP and get it rebuilt

Pics would help, usually a foreign object entering a turbo does more than bend blades they usually tend to fly apart and implode and I doubt it would have only damaged one blade as well since usually anything entering the turbo bounces around off the blades before beeing sucked in.
