Well, did you bump the record?
#fuelmuch?

I was not able to "bump" the record before the melt-down.  Best pass at 2016 WOS was 132.xx mph on the 2-1/4 mile "Short" course.  Record is 135.003 mph.

That's a bummer... Have you thought about coating the combustion chamber surfaces? Do it doesn't torch another piston?

Here is footage of run #5 of 7.  This is what I consider to be the last "good" run of the 2016 season for #672 H/DT.  132 mph and some change.

Good idea for "next" time.

IMHO, looks like piston "debonding" to me. However I have been wrong at least once before in my lifetime. :-D  Good luck with the autopsy for the cause of it's demise. We're all watching and waiting.

Life is an abrasive. Whether you get ground away or polished to a shine depends on what you are made of.

I have seen guys polish piston crowns, the head side chamber face, and face of valves. It supposedly reflects heat easier.

I do know, trying to tig weld polished aluminum is significantly harder to get a puddle started,, it takes a ton more juice, but once it starts, flows out just as easily.

Another test, would be polish a nut, and then try a heat comparison with a non polished nut. Heat with a torch, see which one turns red first.

These are just another thought for "next time" trying to prevent the next "next time".

For anyone interested, here's video from the final (and fatal) pass #7 of 7.  This was with my friend, (a rookie driver) at the wheel.

Upon reviewing the video, there are several things I'd do differently.  This was the 3rd pass in a fairly short period of time (back to back to back passes).

Before this run even started, the water temps were too high, and only got hotter.  EGT's look like they were maxxed out before the top of 3rd gear, as well.  (Guages are from left to right - EGT, Oil Pressure, Oil Temp, Water temp, and Boost).  The blue/silver thing under the tach is a GPS speedometer.

Anyway - live and learn....

I took the injectors to St Louis Diesel Injection Service to have them tested.  The tech there said they all looked "perfect", so at least I know a bad injector was not the problem...

OK - time for a little more ugliness (you have to hit rock bottom before rising back up, right?)...



Here's a peek inside the exhaust inlet of the turbocharger.  Seeing metal "crumbs" at this location cannot be a good sign.

Then, we get a look at the hot side turbine of the turbo - I hope no one else ever sees this in their turbo - apparently they are not designed to ingest liquid metal...



Last pic for now - sadly, this scene is becoming all-too familiar and frequent: (out with the bad).

Steve,
        Nice to finally meet you and thanks for loaning Jerry your sealant.

Bummer about your engine/turbo.   :-(

Don:

Same back atcha (except you didn't loan me any sealant).  I hope the Hylomar helped with Jerry's intake issues.

As far as my engine - I'm chalking it up to my own lack of good judgement in terms of the tuneup and prep on the engine.

I've already started collecting parts to put it back together.  My goal is to run both a 2 liter and a rebuilt 1.5 liter diesel next season.

Steve.

I think we've seen enough ugliness on my build thread for a while.  How about something beautiful?

....like maybe 400 ponies in a box....
