Solenoid failures?
Solenoid failures? Who has had a nitrous solenoid stick open on them? What was the brand? I'm looking at buying a used kit and am worried about the "off brand" solenoid causing an engine failure.
I have had a NOS super shot solenoid stick open due to electrical, and one Dynotune purge noid that stuck just a tad open due to moisture getting down my purge line. Mostly you will find issue with the small noids not opening due to excessive pressure and/or heat. Make sure you use a good nitrous filter at the bottle, and a screened solenoid fitting at the solenoid itself. really the filter itself should be at the solenoid and no screened fitting, but most put the filter at the bottle area. that leaves debris from the line itself. Really that's the only way a nitrous noid will stick open, debris. Get good quality large solenoids and should be fine.

To minimize if not eliminate that problem run a good filter. My self, on my direct port dry set-up, even though I run big powerful quality noids one per bank, I am still thinking about adding one 700hp noid at the "T" that feeds each side. That way should one noid fail, the back up noid will still shut the system down and save the engine.
The thing we have to be careful about running redundant solenoids is making sure that they have a orifice size capable of supporting the size N2O hit sought. Here's an example, the 5177 with redundant noids is limited to about a 135rwhp shot due to accumulative orifice restriction. If you take one noid out of the picture then you can do like a 175rwhp shot. So back to back noids can be restrictive according to orifice size.

To the point above a filter is key - with any solenoid if you get debris in it it can stick so a filter is always recommended. Also make sure where you get your bottle filled has a filter on their setup as well. Going on our 9th year in busy with thousands of solenoids out there we feel our solenoid's record stands on its own.
I would go with what evilbeef said - if they are used a rebuild is cheap insurance. Do it for sure!
