N2O baackfire = exploding hood.
I just sprayed the car with a ~100 shot.. All was good and a/f was ~10.5 (a little rich). But, the pressure is still at ~1200 (it did hit 85* today, so maybe that why?) or so and wont go down. Knowing this, I changed me jettings..
The person taking the video has Parkinson's disease or something. Holly get a camera stand batman. Almost made me sick watching that.
Maybe a dumb question but are you sure it was caused by the nitrous and not just a bad hood?

Is the bottle temperature up high. If so this may be why the bottle pressure is staying up high.
The jetting Nano is giving out is nothing more than a suggested starting point so keep in mind you still need to varify airfuel.
Sorry to see that hood get blown up like that. I know that was a grand down the drain..

I put the jets sizes that I know is a little rich in today just in case the NANO spiked again.. It was consistent today, but was a little hot so maybe that explains the increased pressure today.
But, on that morning at the track, it was ~10:45am and ~70* outside. When I turned the bottle on it was ~950 and was good to go. In the ~5 sec. I was into it, it backfired then got back to the pits and saw the pressure at 1300psi..

Verdad Gallardo Well, I got a PM from a nano rep. and they will be contacting me to see what can be done.. Today I tried to get the pressure down and it took ALOT of purging to even get into under 1100. But, at this point there is not much left. So, we are working on a solution. I would just watch the bottle pressure.
I wonder why that is. seems if you were to run it at the nitrous manufactures rec pressure there would be no issues and thus no need for re-tuning. Am I missing something here? maybe they think the 950psi is the optimum pressure to run n2o at, as per NOS and hope that retuning won't be a down fall to most IE: cost. To me that would be a bitch. ok i just forked out X amount of dollars for my rather expensive nitrous tune, now I need to do it again. Not a good marketing move IMO, unless there is an underlying reason.

So, with it being liquid, it requires ~20% less N20 or just up the fuel to compensate.. But if you go up on the fuel side its a bigger shot then what you think.

From what I understand why is... It is pushing the liquid up and out the noids and into the motor instead of the gas's that comes from using the bottle heater.

Well, nothing sounds messed up.... I have taken it for a spin and all seems to be good to go.
So then, we all need to know that a re-tune will be needed if running the NANO kit? If it requires 20% less n2o, then it seems it could be compensated for by lowering the pressure set point on the regulator. though that would likely be a crap shoot and prob be better just to re-tune and be safe. God I love learning n2o stuff, and anyone whom claims or tries to portray that they know it all, is a dumb azz, lol. thanks

Im not sure if we are on the same page here... Leave you N/A tune alone and leave that where you consider safe. Most people are about ~13.1 AF N/A.
Just do simple math with picking the jet sizes for the NANO shots.
Pretty much if you want to run a 100 shot NANO, just use the 75 shot N20 jet (whatever NX number that may be) and use the 100 fuel jet (whatever NX number that may be).
That a 25% decrease in N20, but it should be a safe start.
I talked with the NANO rep today and they suspect the regulator got damaged during the N20 fill... So, I was told to unhook the NANO braided line from the check valve on the N20 bottle...
Well, I had it WOT throttle till I saw the hood fly off.. I had both my cut outs open so I did not hear a damn thing, just saw the hood fly off. FYI, the foam around the seal (where the hood seals to the square opening) was all melted to ****.. I did not have my air filter in at the time so that why I did not have a fire.
