Good vid.
What messed up for the nawz to back fire?

In this case, a 200 shot is a lot of nitrous/fuel to be spraying. Assuming you have the nozzles spraying at the perfect angle for uniform distribution (and that is a moving target) you still need high airflow to suck all that down without it pooling in the intake, and that is what happened here I bet. Ends up with so much liquid fuel in the combustion chamber that instead of a millisecond long explosion you get fractions of a second long burns - which means the light is still on when that intake valve opens. Kaboom results.
I've seen air cleaners look like that before, too: there was so much fuel in the intake that the explosion blew some of it out of the filter before it could find the oxygen it needed to join the fun, then after the initial explosion was done it went off, caving in the filter.

Or combined with driver error: spinning 1st and instead of riding out 1st gear the driver short shifted to 2nd (or trans was left in auto which means it would short shift by itself). That much lower rpm and therefore airflow thru intake combined with that big 200 shot results in same effective result.
Ported nitrous setups are preferred for a reason. Yeah sure they are more complicated and cost double a plate setup, but they eliminate some engineering failure points which reduces the impressive amount of blown engines and popped intakes' stories that are floating around out there.

I think we agree, you just like to be long winded. lol

A nitrous backfire is what concerns me if I were to go nitrous. I would not even consider nitrous without a window switch though.
Good fat tune and a window switch would be the safe bet.

You need the RPM up to ingest the nitrous. You spray nitrous in the intake, the cylinder has to suck it in. Too much sprayed at too low an RPM and this is what you get as it is just a fog of spray and fuel in the intake that is going nowhere. That's the readers digest version, but I think you guys can understand what I'm saying. I've made my fair share of mistakes with the bottle when I was younger and playing with 5.0's.

Proper safeties:
window switch/progressive controller
WOT switch
Arm switch
Toon
Fuel
All of those need to be setup and proper to make nawz safe. The street guys I see having these issues are running a ghetto system and missing some of these items and make a mistake.
