Anyone ever blow their engine at night?

I dunno if this is a weird question but has anybody and if so canyou give some of the details, like what exactly blew, possible reasons and the condition of your engine at the time. I'm curious about a few things.

Usually it's on a hot day pushing redline up a hill or underload while downshifting. This is apex seal failure not coolant seal failure.

A week or two ago, I was driving home from work at like 10 and I thought I blew my engine, but when I got home, I figured out it was just my map sensor.

i did. i would think that apex seal failure would be more likely on a cold night than a hot day because the air is denser so you get more boost spikes...

i think you would be more likely to blow a coolant seal/water jacket on a hot day for obvious reasons.

at night it is cold and easy to over boost (ie boost spikes). I hit 15psi on new years this past year when racing this girl (turns out shes now my gf ) but didn't blow the motor because of an upgraded ecu but I was LUCKY, injector duty was way to high!

I blew two of the at night. I blew the first one because a turbo gasket was gone, and even though my gauge said I was making 12 psi, the turbos were have to spin a great deal more than that to produce it, so I guess I ran lean. That's the explanation I got for that time.
The second time was more clear cut. I had just installed my EFI and was doing pulls at 12psi, and a chunk of carbon went through my seals. See, I babied the car for a long time because I was hitting fuel cut, so a lot of carbon built up. So as soon as the car ran correctly, the carbon broke off.
I didn't even know until I got off the highway, and was at a stop light. At that point, my idle was rough, and I was only pulling 10 lbs of vacuum.
May you never see these experiences first hand.

Jim
