I have been running the Zex kit for a couple years now and pretty much have been incident free. That is until yesterday. Went to the track and on the first run, ran out of N2O. No big deal. Change the bottle, fire up the bottle heater, go out for run number 2. Purged fine with a nice white cloud. Come out of the hole, hit the button, nothing. The only thing that happened was that might A/F was at about 9. I assume no N2O, tons of extra fuel. Feels like I am pulling a boat anchor. Unarm, ride it out. Get to the pits and check bottle and pressure is around 13-1400. Could the solenoids have possibly been locked up? I remember Dan mentioning this awhile back but can't recall the end result. Chad and I also checked the system after my last run and now the NMU was not spraying the nitrous. We had to reprogram it. After that, it seemed fine. So my question is this: Will excessive pressure lock up the solenoids in the NMU? Thanks in advance.

at 1300 psi you froze the solenoid.You gotta keep them under 1100 psi Gary.

I found my Zex never liked to fire above 1000psi. Also One night it wouldnt fire and I had 950 psi. I tapped on the Zex box and it worked. Now I think my problem was at the time was I was not running a in line N20 filter and the noids may have got some rust in there from a bad fill or something.
The next day I installed a filter and it worked fine for another 6 months.. Hope this helps.
Keep me posted on the switch and if you need any help let me know. BTW Why the switch?
