I spoke with one of the forum member today about safety on NOS setup. And he mentioned about having dual NOS solenoids setup. Just set them up one right after another on the same NOS feed line. This should will provide redundancy in case if one of them fails and sticks opens.

What do you of it? Any down side?

I also wanted to put a second NOS sol. inline, but couldnt get the fitting between the two.
No vendor and even not NX directly couldn`t make it for me (or didn´t want to).
If you ever get such a part and you have the NX set, let me know.

Also it may restrict a little so you may have little less flow on he 150 shots.
(that´s what I heard)

No downside that I can think of, except for the cost of another solenoid. NOS does make a small fitting to join the two solenoids, they sell this with their LS1 kit for the Z28. I've installed a couple now. :seeya

$80 is very cheap insurance to gard against a NOS solenoid sticking open. I leanning toward dry since I will only have one solenoid to worry about.

Anyhere has problem with the MAF reading the extra air coming from NOS? I'm just a little concern about depend on two thin wires within the MAF.

The NOS dry kits come standard with 2 solenoids in series.

Anyone knows if it's possible to do the same setup with TNT or NX?

I have the RM/NX nitrous kit that has 2 N20 solenoids on it. I will look at mine and see what kind of fitting they use.
The only downside I can see with 2 solenoids is, when 1 solenoid fails(stuck open) you wouldn't know it failed until the other one fails.
The best protection besides a filter is to replace the solenoids every several years of operation.

I would be more concerned with the relay for the solenoids sticking. I have seen electrical contacts on relays actually arc weld themselves together. Doesn't happen very often and it does take quite a bit of current to produce that can of arcing like on a relay for a home AC unit. Still though, two solenoids (one fuel and one nitrous) pulls alot of current. if you were to take a wire off of the solenoids and apply it directly to the battery terminal, you'll get a pretty good spark. the relay contacts see some sparking action each time it closes with that kind of current flowing through it. Although I haven't heard of any cases of relay contacts for these nitrous systems fusing together, I haven't heard of any solenoid failures either. I think as mentioned before by someone, the best thing is to have your solenoids checked out after so many uses. Maybe keep a couple of spare fuel and N20 noids to swap out on occasion while the others are sent in for rebuild. I believe NX Express offers free solenoid inspections for theirs. (I think) Somebody correct me on that if I'm wrong.

Com'on, I'm sure someone here will figure out how to get notifications on solenoids failures. Where are all the computer geniuses? :lol: :lol: :lol:

Any one with ideas on this?

Electrically speaking, this would not be a difficult task to accomplish. From a plumbing perspective, it would be a bit of a pain but could be done.

What would be required are pressure switches after solenoid 1 and solenoid 2 and a sequential control of the solenoids.. Then a couple relays to detect when pressure exists at the same time the solenoids are de-energized.. Fire a red light for the error, use a relay contact to prevent further engagement of either solenoid.. and your're done.. no biggie..
