Competition Shoulda been there-Bradenton.

Went to a test & tune Saturday night and watched a 4X4 Duramax make a few runs. Fair burnout with slicks.



First pass was 14. 13, second was 13. 91. On the third run, he let out before the 1000' and don't remember the time, think it was a high 14.



Two street cars then made a run. Just as they passed the finish line, we started seeing thick black smoke drifting across the track just like we have been seeing on TV from Iraq.



After they towed the Duramax back to pits I went to look at it and could see nothing outwardly wrong, the hood was not open. Driver was changing out the slicks and naturally was not talkitive, but did say motor was completely gone.



I prompted with a "Did it just run away with itself?" and he said "Yes, even though the computer looked like everything was ok. "
 
Remember the older Coors cans that had the 2 little punchout holes that you pushed in with you thumb ? I think he musta had one of them in there from the recycled aluminum heads :D



cheers, Kevin
 
Doubt its a turbo seal... That would create plumes of white smoke. Sounds to me like an injector or injection pump problem, creating a HUGE amount of fuel to be drawn into the cylinder.
 
Hope he knows about "thedieselpage". I'm sure they will be able to help him out as soon as he gives his vin;)



Maybe he tried mixing a little hydrochloric acid with diesel?
