EFI ,
With the amount of timing retard and volume of nitrous and fuel being run through the motor , it is normal for the exhaust flame . Not quite a nitro flame , but pretty cool none the less .
Two things come to mind with what happened . First thing I would say is that it broke a valve train component on the exhaust side . Next time around it had to go somewhere , back out the intake valve is the only place it can go . There's your fuse.
Second is he lifted because he saw he was getting beat , lifted and a nitrous solenoid stuck or even the entire system stayed on .
None the less , your right about not trapping yourself against the wall . And with all the people who ran behind the car , you would hope where would have been at least one who would have had the sense to turn the master switch off.....maybe the car would not have been totaled . Happy to see that the driver did not die from being burned to death.....!
