383LQ4SS -

I got to talk, briefly, with the NANO guys at PRI this year...he stated "this is not a nitrogen push"....I have always associated you with the push system...I remember seeing yours a long time ago.


What exactly is different here?

 

other than the fact that they advertise the use of HPA or N2...it looks much like the first setup I built back in 2002. Making use of a regulator to control max PSI and flow. Wether you call it a "nitrogen push" or a "presssure compensator" or any other name seems moot.

I eventually went with a pressure switch solinoid/demand setup that kept pace a bit better. There is alot to a "pressure assist" setup like this. Such as how well the set up works when the "pusher" bottle is at 4500 psi vs when its at 3000 psi. By "how well" I mean what flow do you get at various pressures...and is it enough to maintain target pressure of the nitrous bottle.

Regulator or orifice flow at the various pressures, shot size, etc etc.

I really like there setup...but it can be duplicated for less if you have some skill.

But if not...theres is a nice prepackaged setup for sure.

 

Can you explain why it works better?

 

Nice system and even better marketing.....Is it 850$ for the entire nitrous kit? If so that isn't a bad price.....

 

seriously, thats what I thought.... everything in this market is soooo damn over priced

 

383lq4ss-

do you have a link to your threads? search isn't really working correctly right now

I was hoping for a lil more info

 

fixed the link

 

I had a big long reply typed...but the computer crashed and I lost it.

Here are some old links:

Now the regualted sytems vs the pressure switch/high pressure noid.

The regulator will handle up to whatever flow it can handle at its various pressures. And thats it. A pressure switch/noid setup is expandable and usually outflows most regulator setups.

If a regulator can flow enough HPA or N2 to keep 100% pace with a 300 shot...then it wont have any issues with a 150. But if the regulator can only keep pace with a 200 shot and you spray a 350...it will fall behind. What the actual capacity of the Nano is I have no idea. I will say...ANY supplemental pressure system, even one that cant keep pace 100%, is better than a heater.

In the pressure switch/noid setup you can tailor the setup and expand the setup easier. Hell you could use two dedenbear noids and double the flow capacity. I would bet that would be enough to flow a TON of nitrous at a constant pressure. 600-700-800 shot who knows. SO the larger the shot it would be capable of backing up...the better off you would be at say a 300 shot.

Now I dont want anyone to think I am saying the Nano sucks. I think they did a great job. Its packaged well, easy to install and use presumably, and premade. I dont think the price is half bad either really. Most people that use nitrous are not that experianced with industrial gases to make there own setup. So paying a small premium for the nano IMO isnt out of line.

But for some...its pretty easy to make your own...and do so designed right around your specific kit.
On one of the links I posted the parts list and estimated prices.

 

 

Oh...and on advantage of the electronic system is you can arm and disarm the system from the cockpit. Although nano sounds like they are working on something like that as well.

 

isn't the extra air from using HPA a concern?

 

In what way?

 

I know the nano has supported at least a 700 shot with no drop in flow at all. I'm pretty sure they have tested higher, but I don't know exactly what to, just know the 700 shot was tested awhile back and it doesn't lose any flow.

Yes you can build it cheaper, but I can also build a turbo kit for my car for less than 1/2 the price that the companies selling kits sell theirs for. I know I've done it before, but having something prepacked for the average person who doesn't have fabricating skills or the way to build it safely makes it a great product. It is also completely DOT approved.

 

The regular Nano setup on thier website sais 350 shot. Thats good enough for most. Its like $569. The Competition kit is quoted as being good for 500 shot and it like $659. That should hold over 99% of everyone here. And all you need for DOT approval is to ensure both bottles are DOT approved. Hell...mine was FAA approved..lol.

Again...I am not argueing AGAINST the NANO. Just getting additional info out there about these types of setups. The NANO may be the best option for most. But its not the ONLY option. This site is dedicated to information and thats what I love about it.

If I do another one...I will be making my own with the pressure switch and noid. It generally costs me about $175 to make one. Thats about what I paid for my last one. I have bottles, I have lines,I have fittings, I have check valves. I just buy the Dendenbear Noid and the Dynotune pressure switch. Add some wire and a switch...done!

Maybe $375 if you had to buy everything including a 10 lb bottle.

If you dont have stuff like that in excess laying around your garage, and are not familiar with gases and such...then the Nano is for you!

By the way...The Nano..or homeomade setup is in fact WAY superior to a heater...just as the original poster stated. These setups work GREAT.

 

If you're using HPA and run out of nitrous, you would be 'spraying' HPA into your motor. Wouldn't that cause a very lean condition? Or is the amount of extra air negligble?

 

383,
How can either be DOT approved when you are putting one hazmat into a bottle labeled as a different hazmat? (nitrogen into a bottle labeled as N20)
I could be wrong, but as far as I knew under no circumstances, can you do that legally.

 

Thats true...but Labels are cheap and available though. And really the bottle needs to be black or orange if your using nitrogen. Compressed air I am not sure if there are any color requirements for the bottle. These are additional reasons why its good to have some experiance with compressed gases. And probably another notch for most for paying a lil extra for something like the Nano.

 

I say you market a Kit Al. id be all over that haha.

 

yea, all of our tracks around here stick closely to the NHRA rule book, as do most tracks across the country. They just haven't been busted yet.

Here's my answer. Keep your pressure at about 950, and you maintain a pretty constant pressure through out the run, and this is with pretty big shots. yes, still a little press lose, but minimal, imo.
