I don't care how slow or fast a nitrous car is, any that I have plumbed had a 1/4 turn valve right next to the driver! I also put the nitrous filter right in front of the valve to keep any possible trash from ever getting to the valve.

Ball valve within reach should be a rule. I had a bad crash last summer that had a good fire. Fire system then ball valve off. Took 2 seconds then got my ass out. Nothing should be more important then getting out.

I would assume anyone racing at a higher level than your average street car with 150 shot would have a 1/4 turn valve. I have my 1/4 turn and gauge next to my shifter. I open it after my burnout. it takes 2 seconds to close it if I have a nitrous back fire or something is going wrong. Close the valve, kill power, unstrap and get the fuck out.

You're making a lot of assumptions for a guy that was probably wearing a single layer jacket helmet and blue jeans at best. Never seems to me that grudge and safety go hand in hand

True. My car is a no time car and street raced on occasion. I'm prolly safer than any car I've raced against on the street and that's a fact lol. You do see a lot of backyard mechanic thrown together shit at these grudge events lol.

^^^ What Corcon said. I cannot reach both bottle valves, so I have two 1/4 turn ball valves next to my shifter. Ball valves both "off", & then Ignition switch "off", to stop the fuel pump...will prevent a bad situation from getting worse. Also, EVERY TIME I start the engine I turn it over for a couple seconds BEFORE I turn on the Ignition switch...as a precaution in the event there is some n20 that leaked in to the engine.

That quick burndown looks to be the result of fuel lines being ruptured during the intitial backfire and the fuel pumps running and pouring fuel into the engine compartment..nitrous is non-flammable however just like oxygen it accelerates combusion when a fuel is present... Pumps need to be shut off first IMHO...then the nitrous shut off via 1/4 turn ball valves etc...For a better safety system a 12v
solenoid could be plumbed in line for nitrous supply and immediately shut off if needed with the push of a button or flip of a switch..........

Will you guys please stop repeating the misinformation that nitrous is non-flammable, because it most certainly is. Nitrous does not need any other combustible to release a large amount of heat.

In fact, nitrous oxide is used in rocketry as a mono-propellant because it needs no other fuel or oxidizer to sustain a self-perpetuating exothermic (heat releasing) reaction with the energy release equal to 40% an equal weight of TNT.

The nitrous dissociation reaction is not combustion in the common understanding of the word 'combustion', in fact it is the opposite, the atoms in a molecule are separated, instead of combined, but in the case of nitrous oxide the dissociation releases heat.

The N2O molecule dissociates (splits apart) when subject to temperature above about 575 F and releases as heat the bond energy that holds the N and O together.

When N2O acts as an oxidizer, the exothermic molecular dissociation reaction occurs first, releasing heat and freeing the Oxygen atom from the Nitrogen atoms, the free Oxygen then is available to combust with available combustibles and release more heat.

Was the camera attached to a dog or something? Somebody needs a tripod or Parkinson's Meds.
