Z06 Vette - Nitrous Hiccup
Old Repost

D'oh...ma bad.

NO, that's what trying to spray at 5 rpm does.

Yea that makes perfect sense, leave the line at 5k and spray it and get a nitrous backfire on a WOT switch.

holy crap that was insane. but so awesome at the same time :eek3:

I know the guy actually his nitrous puddled in his intake manifold and ignited. He was using a TNT wet nitrous setup with a window switch that was professionally installed and in perfect working order.

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.

I worked on nitrous systems from small EFI kits to 3 stage Foggers feeding 600+ci engines. Doesnt take a rocket scienctist to install one basic electrical knowledge. Tuning and getting the most out of it is a lil more knowledge then just slapping it on and using it.

[chrismullins99]

It does kinda seem like the guy sprayed with the rpms too low and nitrous puddled in the intake manifold.

I know poop when it comes to nitrous I have only worked on N/A motors and a few turbo cars. I was just telling you all what he told me. From what I have seen of his setup he was running a 100hp shot which is how the shop installed it and dyno tuned it for, with a window switch which from what he said is suppost to only start spraying NO2 at a set RPM at WOT, then shut it off at another set RPM (wire spliced in to one that comes from the Throttle Position Sensor to tell when he is at WOT, and hooked to the ignition to tell RPM, is what he said), he had no purge kit and no bottle heater, he had this kit for 3 years and no problems. I have no idea what his bottle pressure was at, and he said that he dident bypass the window switch. I do think that he did something to it (possibly swap out the 100hp jets for higher ones without swaping the fuel ones to match, which he did once before). We went to get our cars dynoed with a bunch of friends and on his first sprayed run the shop doing the dyno run (and that installed the kit) cut the run way short saying that it was running to lean and that it could harm the car, so they checked the jets and it turns out he was tring to better his 502.4 rwhp by installing alot higher nitrous jets according to the shop owner, they installed the 100hp shot jets and the car ran fine and dident run lean. So that is what I figured happened at the track is that he was tired of running mid 11's and wanted to go faster, and dident jet it correctly.

I only knew two people with wet nitrous kits on there cars on is this guy and the other was a douch who dident know squat and hooked it up himself, and it blew on him the first time he hit it. Most of the people that I know that have dry nitrous kits only run 50 - 75 hp shots and a few run 100 hp shots and one runs a 150 hp shot of dry nitrous on his Cobra. Personally I would think that a wet kit would be better (thinking about getting one so I looked into it a little bit) by the way that it is set up.

Here's a retaliation video to the dumbass at the end that insults the guy!!!

He got OWN3D big time on this.
