When should they get rebuilt and whats involved? Thanks.

 

I was told that they should be rebuilt if they have sit for awhile, like over winter and such. I think once a year would be enough, depending how often you spray. If your going threw a bottle a week, then maybe rebuild more often. When I went to rebuild mine I ordered replacement plungers from dynotune. Look for crud in the noid and seals that look bad.

 

Whenever you decide to freshen up the solenoids, be sure to use teflon plungers. They last a whole lot longer.

 

I think this is going on the 3rd year for mine. The 1st year I ran ~40 bottles and last year I ran ~10 bottles. I have not sprayed yet this year.

The car sits in storage for the whole winter. How do you check/take them apart? How much are parts and what to replace?

I havent really looked at them to tell you the truth, I just dont want to take the nut off and crap come falling into my lap and saying, o'snap, hows this go back together sort-a thing.

 

naw. its not that complicated.

I think the replacment plungers for mine were $15.

 

How can a plunger go bad? Im assuming just leaking right?

 

These are the replacment plungers I ordered, of coruse I went with dynotune products, but im sure what ever kit your running offers them to.

Heres some instructions for rebuilding dynotune noids, should be about the same as all other noids.

Well I thinjk basically crud can get in them over time and then they can stick. Also the seals can become misshapened over time because of pressure and then cause problems.

 

Thanks for the links, I have NX so I guess ill have to get it thru them...

I would assume that the seals would go out alot more then the plunger though.

 

Im looking at Nitro Daves website (thats where I bought my kit) and I found the NX parts, is it 52 bucks for the damn plunger (I guess they call it a piston)?

Yeah your prob right. But if your trying to decide weather or not your plungers and springs need replaced I'd just go ahead and replace them. Its prob cheep insurance. Sometimes things dont go so well when/if they fail.

 

wow that suxs. I'd call or PM one of the nitrous outlet guys and see what they recommend.

 

I just cant believe its that much.. If they are, then I guess ill just clean them and replace the seal/o-ring.

 

The plunger is what goes bad.

 

I guess your noids must be "better" than mine, cause I can replace a whole noid for $59.

 

Is that what they have labeled as the piston in post #10?

How would it go bad?

 

Swelling, cutting, debris, tolerances...lots can happen to a plunger over the course of time. The amount of lift coming off the base of the solenoid is not as much as some people assume it is and minor variances within the plunger can alter flow characteristics, sealing, etc.

So, this will result into leaking?

 

It can. It can also impede flow through the solenoid as well.

Well, I see your noids ar ~$60 bucks for a bran new one... And, the NX ones are $57 for a plunger and o-ring. WTF are NX's so damn expensive? Can I use other then NX parts?

Do the fuel and N20 noids open the same distance? I am temted to just verify that to make sure they are equal and check for leaks and call it a day..
