I was amazed at the amount of metal in a drag engine con-rod.
From Quora...
How do high horsepower race engines not tear themselves apart, i.e., a 12,000 HP (claimed) drag racing engine?
Sometimes they do…
This is Doug Herbert at the 1999 Winternationals. The motor grenaded right at the hit of the throttle. It’s commonly agreed that this is the largest explosion in NHRA history.
Note how far down the ring pack is from the crown of the piston, and the connecting rod speaks for itself.
The other thing to note is the fact that the motor turns over only 1000–1500 times under full power on a 3.65 pass. Piston and rod assemblies are replaced after every run, and the motor is completely torn down and everything is inspected as well between runs.
The fuse is pretty short on these things.
