I ran a 8.1 @ 84MPH in the 1/8th mile. Which would be high 12's... but yea, I still let it cool a few minutes after coming back around the end of the track. I did hot lap it a few times as well, but on a rare occasion.
I've never come across that.. I will say though, I've never let any modern diesel I've owned "Cool down" just after normal driving. I've pulled 15K+ with my last Duramax and yes, I did wait 5 or 10 minutes after getting to my destination but never on just a small load or unloaded truck.

If you go back in the video you'll see him talking about installing the kit, etc.. pretty informative.
Well, you would think I could read.. :D Sorry about that.
Anyways.. that's not very many miles! It's weird how these things just tank so early sometimes.
