Boy the turbo is almost new to.

 

Damn, seems like a defect. Any scoring in the castings?

 

 

Damn Leonard. First Tristan now the truck... So what is your plan? Warranty?

 

No harder than I had been before. Maybe the prior runs helped build to this though.

Thanks guys. I'm gutted for many reasons besides the failure itself.

I don't know yet. I will be removing it from the truck for a close inspection today.

Hmm, were you kidding or serious? That kit has only one review, and it's really bad.

Yup, I'm going to see if I can get it warrantied first. In a way, this has helped me take my mind off Tristan. It's not a good way, but it's a way.

 

SP Turbo BW S300

 

Nice find Dan, that is a good option if the warranty process does not go as planned.

Although, I would try to (and I am sure he is) get to the bottom of why the failure happened in the first place. He has 205/80 injectors, hot and mild tunes, Turbonator, Tapercore IC, 366 super core, built motor from Swamps, etc...

I am grateful that the engine appears to be find and despite the catastrophic failure of the turbo, something is NOT right with the setup. Maybe the turbo is undersized for his other high end and max power parts, I don't know. The 366 SXE is said to be rated for 700+ HP, but I know these turbos are used in a vast amount of applications. I don't know what happened and we may never know, but I am hopeful that the turbine, vanes and Turbonator are OK and that Leonard can get to the bottom of this in short order.

As I said earlier, cutting edge parts and technology does not always work out the 1st time, as a matter of fact, there are usually many failures before success can be shouted down the hall.

Sorry again Leonard, I would like to offer some help, but due to distance, all I can do is look at pictures, videos and offer some advice.

 

That sucks. I was so looking forward to checking out your awesome ride.

 

I've always understood that drive pressure is what kills turbos, vgt being added to a charger not designed for it has to put stress on the shaft.

 

This is just speculation, it almost looks as if the turbine shaft itself broke in half.

 

I agree with that speculation based on what we know...

I told Leonard this morning that "perhaps this 366 failure is a blessing in disguise and that we are hoping for the best possible outcome".

 

The Noob has been keeping a good watch on the EBP. It seems this shouldn’t be the cause but

What if the VGT is causing the shaft to accelerate too quickly making extra stress?
This is the only theory I can come up with.

 

EBP is measured in the manifold, actual drive pressure here is force placed on the turbine that is what causes shaft failure.

 

Based on the play....I think you are correct.

 

You guys are exactly right that the shaft broke. I discuss why I think it broke a little further down.

Excellent find Dan, thanks. This may be the route I go if BW doesn't warranty the Supercore.

Don't discount moral support. It helps more than you know. I have one possible cause for the shaft breakage and that is that I have noticed what sounds like surge if I'm boosting and I get off the go pedal abruptly, like when a lady in a BMW SUV (Dan, this is the BMW I was telling you about) cuts into my lane in front of me without looking. If that is the case, a blow off valve may be in order. Either that or get a turbo that doesn't have to spin so hard to make the boost.

And now for your viewing pleasure, pictures of carnage.

Valley is dry. Pedestal quad rings are holding up.


No aluminum shavings in the compressor outlet which is good.


First view of turbine outlet after DP removal.


In case you're wondering, yes there is supposed to be a turbine there.


Oh, that's where the turbine is.


At least it popped out of the Turbonator easily.
