Turbo drama
 

For the record, I searched.:noob:

I just bought a new Godspeed T3 turbo, put it on, primed it, and started it. Drove for about 50 miles while not boosting. Then I boost once to 3 psi, and all of a sudden no boost. Drive back home and discover it has shaft play on the compressor side. Radial and axial. Never took it off to check the turbine side. Enough to barely scrape the housing and would obviously cause the no boost problem. What happened? I never touched the unit at all. Just put it in. Manufacturer defect?

Is the turbo water cooled and are you utilizing it? How was the shaft play before? Check your wastegate to see if they're holes in the boost signal or your wastegate is loose or disconnected.

Turbo is oil cooled only. Shaft play before was none. It was brand new. Wastegate is tight, and no holes or leaks.

shit sounds like a defect, try to get a replacement from ebay, good luck.

Does it sound absolutely horrible even when not in boost (grinding sound)? My ball bearing OBX turbo totally died after about 5 minutes of driving but the shaft actually bent a bit. If the turbo is still quiet and you can see it spinning freely then it could just be something as simple as a coupling that has blown off.

LOL, Ebay parts have a fingerprint guarantee - "we guarantee it until your fingers touch this shit"

If you find and can prove manufacturing defects and used Pay Pal you may have a chance.

Or you could send it to me for an 85 dollar rebuild :). Unless the shaft is bent.

Damn, this sucks. A leaky hose to your WG would cause more boost not less. I am calling defect, since the wheel is touching the housing. Or you screwed up hooking your oil supply up. That would be the first thing I asked as a seller. It would take a special kind of idiot to screw a turbo up enough on installation to cause this.

Yeah, oil lines were hooked up exact same as my old volvo turbo setup which ran fine. The company is sending me an app for warranty. If I don't pass I will definately send you a message rider.

Godspeed is supposed to be good.

How exactly did you prime the turbo?

3X, I pulled the plugs, injectors, and cranked for 10 seconds. Until I had pressure.

other then warranty purposes, why else do you really need to prime the turbo with oil?

If I am correct, the turbo doesnt see any sort of real load at all at idle? Just something like a slow rotational speed of like a ceiling fan or so? No real load or stress, I wouldnt think enough to cause it to damage before the car builds oil pressure...which takes how many seconds from firing to running?

The play could have been there and missed or maybe the bearing is sort of oval so it only has play in one direction or axis...

You still might not have had oil in the feed line. I'd recommend in the future pulling your ignition cable, removing the oil feed line, and putting the oil feed line into a clear plastic bottle. Crank until oil comes out at a steady rate. Took a really long time for oil to finally prime through my -4an line.

What I usually do is hold the shaft of the turbo and get someone to start the car, and just sit there and hold it until I feel it get loose and want to start spinning. This can actually take like 5+ seconds
