Broken Turbo

What do you think about this?

How can this happen if it's NOT something bad passing through the airfilter

Looks like something did pass threw it, BUT I have heard where just the wear and tear of all the pressure on the blades when the throttle is slammed shut while there is still alot of boost in the intake tract causing problems with the impeller. Unless you have a blow-off valve. Not really for certain on this one.

that def looks like an airfilter problem.

all the talk about BOV's I've never seen a broken compressor from not having used one.

I am with waller on the BOV thing.. it is hard on the thrust bearings not the compressor wheel. I know quite a few guys that run big turbos and even with sticks that don't run them.. they don't want to chance any leaks... I plugged mine... POS.. I could hear it hissing when I was trying to boost on the line.

the way i like to do it, is tach the motor up to about 4000rpm, then slowly start feeding the turbo cheese puffs. makes a great BBBBZZZZZZZZZTTTT sound.

Leave it to E-RUE to feed his turbo cheese puffs. Sometimes I wonder where you come up with these idea and then I realize I am probably better off not knowing....

Do you ever search and read through your old posts?

I have no blowoff valve on my truck. I thought it was unecessary when it was an automatic transmission and a PT Turbo. I thought they could withstand the pressure?

I'm almost 100% certain that it's not the airfilter. Should I get a blowoff valve? I want to "hide" the blowoff-sound if possible, I don't want people hearing I have juice under the hood.

I guess it's impossible but it's still nice to try beeing a "sleeper", alot of ppl in my home town still have no idea what this truck is. All they know is Volvo / Saab with aftermarket memcals.. 8) .. There's a guy here who sais his volvo will beat my TY @ the quartermile.. His last pass was 13.5 secs. He wants to bet me 5000SEK (about 500dollars), I think I'm up to the challenge. Just as long as I get my turbo back , just had the tranny rebuilt and a new torque converter 3500RPM stall..

My suspision is that the turbo couldn't handle the pressure of the high boost (about 25-26psi) or that someone bent the blades while trying to turn the compressorwheel when adjusting it for the turbo to intercooler hose.

It's my turbo and I'm getting it fixed, I'm just trying to find out if I could file a complaint about the turbo, so maybe I can get some money back for the new rebuild of the turob. This will cost me alot of unecessary money, bought the turbo this spring and I was hoping for a Speed-Pro system, however this is about a 3:rd of the speed-pro cost, just fixing the turbo.
