At 7,000 rpm part throttle...who would have guessed?  Likely began moments earlier at full throttle.

As one of our B.C. racers said "Been there, done that, hope never to repeat."  In his case, 2 Lotuses were leading, the trailer playing silly bugger, deliberately slowing the Mini down in the corners and under full caution, helping his running mate to build a bigger lead.  After the disintegration the dawdling Lotus quietly took the track exit after the main straight.  Let my views be known to the Officials - the 2nd Lotus should have been black flagged and parked long before the engine blew up.

Wow. Would like to know what RPM that was at...

Looks to me like crank failure between 1 + 2  that let the whole front of the engine be torqued and broke off.
I assume the timing cover held the front of the block in place.. while all the spinny pieces inside ejected.

 
suprising the bore bottoms arent more banged up,


Or Could crank flex be pulling on the bearing caps and pulled out the #1 cap? pulling out the whole front of the engine too?

is impressive. Im sure someone skat their pants too when that went bang,...

Ok... right Spank.
I was viewing the post on a small 7" tablet. A 20" screen helps!
On the small screen, the grenaded block looked like an exploded gearbox, I've never seen a timing chain cover with a horizontal crease before, and the tray of bits was too small to decipher!
(In my defense, I've never blown up an engine!)

I am amazed too!

That's ALL mini.

And I'm impressed.

I think the first clue is "another racer's windscreen".
I don't recognize any of those bits as being Mini (classic) pieces.

Every now & again things grenade.  One con rod ended up in another racer's windscreen.

Not mine & not telling tales...
