Cold Fusion, Dyno Tune and I think Edelbrock have new solenoid type openers similar to the NOS type but supposedly without the surging/not opening/not closing problems that seem to plague the NOS opener. Anyone try one of these yet? How are they working?

I will let you know from that the surging is caused by a pressure drop and flow restriction caused by a solenoid type opener. The nitrous goes from a liquid to gas when it crosses over an orifice (solenoid).

The dyno tune one has a .250" orifice so I wouldn't imaging the phase change would be a problem.

It will phase change and cause a hp loss. any time you go from one size to another it phase changes. The HP losss may be min. but its still there.
Let me know always interested in differnt ways of thinking.

I certainly appreciate the input, I'm just not sure it's a factor like it is with the NOS solenoid since the orifice is as large as the 4AN hose once the solenoid is open.

Anyone actually using one?

NX makes the best opener on the market. It actually opens the bottle.....no orfices, no restrictions. I've been using mine for three years without any problems of any kind. It was SEMAS's new product of the year a few years ago.

(disclamer! I hate the NOS opener. I have one and stopped using it. NX makes the only real opener IMHO)
you state that " any time you go from one size to another it phase changes"
I dont want to be a dick but if that was true than it would change to a gas when it went from the bottle (large opening no velocity) to the siphon tube (smaller opening greatly increased velocity) The solenoids are an even greater restriction. The single greatest factor that causes the liquid to change into a gas is the latent heat of evaporation. that takes place when the cold liquid absorbs the energy from the inlet air acting as a direct contact heat exchanger.

You are correct. The older style NOS with the smaller orifice could lead to a problem. Our solenoid with the .250 orifice will not cause an issue. We use this solenoid exclusively for this product.

Since the market requested this type of opener we designed it. Though as some mentioned the style that opens the bottles remains the favorite of most with Full Billet construction, Quick release head, no tools needed to remove the opener, Open access to all ports, Built in carry handle and a drive gear doubles as manual valve handle!

A+ for converting opinion to FACTS....

The solenoid style opener that we sell as well as Dyno Tune is a great product for safety and does not cause any power loss. However, if you want a opener that actually turns the bottle handle that is a true bottle opener. Not knocking our own product. I like both styles and they both have there advantages and disadvantages. Cost is also a issue and for a lot of racers the solenoid style opener is a great way to get the job done at about 1/2 the cost.

Dude, I was agreeing with you?!??!!!! was not throwing rocks!!!

So back to the original question, sorta... of the solenoid types
are any judged to be solid, reliable and leak-free enough that
you could leave the bottle valve open all night, and not lose
more than an ounce of happiness if you didn't energize the
opener, against a leaky downstream system?

Or leave it open full time and still be a non-significant-leaker?

It is a tight seal and is designed not to leak at all. It was designed for this purpose.

Mike I apologize. I see now that I misunderstood and am a complete a$$ I deleted my coments and hope you exept my apology
Now back to your regularly scheduled tech discussion

The solenoids are a restriction that is why the large orfice noid will flow more though any given jet size. The siphon tube is in liquid so there is no change at that point. It only changes when there is a point were the liquid can expand, ( I did not explain completly) We did some testing years back with the solenoid type with a large orifice ( for the time ) and saw a 12hp loss on the chassis dyno. 12hp is not that much when look at the big picture but if did loose power. If price is an issue the solenoid type will work just fine.

I bet that the 1" of 0.25"-orifice solenoid, is not much of a
factor compared to 12 feet of -4AN forward line (let alone
the front jet). But somebody running an "open hose" might
have to use the screw-type on a high-flow-valve bottle?

I agree with Nitrous Mike, heck, I agree with everyone.
The NOS opener is only good for low Hp applications.
The Newer generation Solenoid openers are aswome and affordable.
Little to no hp loss unless you were looking for big hp! The 4N line is a massive restriction compared to the Solenoid with a wopping .250" orifice
For the folks with lots of cash, the top mounted openers are sweet.
What ever happened to the NOS top mounted opener? Anyone seen one?
