There could also have been an air leak on the intake manifold, causing the same effect. The engine was already warm, so all it would take is some oxygen and fuel to ignite.
To be quite honest, I'm glad it happened. Nitrous is a cheap way to win. The owner should actually try doing work on the engine to produce horsepower.
Some people prefer to 'add' 100-ish HP using nitrous rather then heading down the engine internals track which will take longer to get that 100hp. The trade off is what we get to see in the video.
Might as well add a story here:
The company I work for drag races a Skyline R32 GTR and their current personal best is 8.4 @ 162 mph with around 1200odd hp. Their competitor ran a heavier GTR with a bigger turbo and nitrous pumping out around 1400hp. They ran an 8.55 @ 166mph. The need for nitrous came from their massive turbo, without it the lag off the line was so great they only managed high 9, low 10 second quartermile passes..
