Sad story really but anyhow his insurence covered it, and he ordered a brand new C6 Vette. All of his friends that had nitrous on there cars sold them and they are all working on new cars now. Kinda funny how the only two guys that had wet kits on there cars had them go up in flames and yet I have several other friends that have dry nitrous kits that are running the same nitrous shot as the guy in the vid above and they havent had a single problem with them.

Not doubting you and your friend in any way. Weird things can happen. But I personally have dealt with all kinds of nitrous problems for many years. From different nitrous systems from N O S, Top Gun, Barry Grant, and NX. You can call any technical troubleshooting techs on any top brands and they will all run down a list of these problems. #1 How much bottle pressure was you running before this problem , #1 problem of nitrous backfires. I have personally destroyed a $500 hood and a few power valves on a plate system with a small block with too much bottle pressure , I left my bottle heater on too long and didnt purge enough pressure out of the lines. I learned from my mistakes on that occasion. #2 What type of switch was it on , a relay on a microswitch or hand button ? ...Normally when someone has a clutch car bogs off the line accidentally hits a hand button not watching the RPMs. And then the nitrous puddles in the intake due to low rpms and ignites from not enough fuel mixture and vaccum to force the nitrous in the chambers. # 3 Was there any leaks of nitrous on the lines ? another ignored mistake leaking nitrous into a intake would cause what happened. #4 Did you have your timing properly adjusted per 2 degrees for every 100hp jetting. Another mistake easily over looked. But there is no way a dry shot is going to work better then a wet system. A wet system is going to have proper atomization from a fuel solenoid and nitrous solenoid in this case spraying into a fogger nozzle into the throttle body. A dry system is a bit different having the CPU to force more fuel into the engine and over working it and not supplying enough fuel pressure thats why dry shots only work up to 100hp shots (recommended with a higher fuel pressure regulator) You might have a bigger jet for 100hp shot in a dry system but your going to risk alot doing it , which is what I think this guy was running IMO.Causing it to run too lean or not igniting the proper mixture on what he says a nitrous hiccup or backfire. If this system was professionally installed then the owner would know the do's and dont's supplied with his kit on the owners manual. A nitrous system is going to work properly if you have all the do's and dont's checked off. My theory is that since this happened so quickly leaving the lenses, there is no way the nitrous is going to puddle up in the intake behind a solenoid activated by a WOT switch without too much bottle pressure behind it. This is what happens when the nitrous ignites before the fuel... its happen to me , its happened to many friends. Ive seen it all the time. And its user error not a nitrous system error. Only other theory how this happened was he was using a dry shot , jetted the system way to high for the fuel to compensate and the engine could not make up for the extra atomization which caused it to ignite inside the intake and instead of shutting the car off and ran from the car it wouldnt have happened so bad. I feel sorry for the guy too but Im sure he knows the real story or has been told and has learned from his mistakes. This is not a one system over the next is better conversation but there is defiantely user error and someone just doesnt want to say I f*cked up.
