I want nitrous on demand and was told NANO would do it.

When I talked to my tuner guy he said he called Nitrous Express and they said: The way NOS systems are designed, as pressure increases the temperature increases. So you heat it up and you get the pressure. So what this means is when the pressure is low, the NOS is colder but you get less in the motor. And when the pressure is higher, you get more in the motor but it is at a higher temp. When all is said and done the pressure and temp balance out. So when we tune for it in the ECU, it really doesn't matter what temp or pressure it's at, as the tune will be the same regardless. If you introduce a propellant (like nitrogen) the NOS could potentially be really cold (pressure is low in the bottle) but be injected into the engine at a higher pressure. Theoretically, the tune could be lean as we really can't tune for this condition.

The short version, the tune could vary based on the temp of the NOS more than it will now.


I'm not sure what he said but what I think he said was that with the NANO there is no optimum tune that will be solid in all temperatures.

Is this true ?......Can adding the NANO system be harmful to the motor because the tune cannot be properly made due to varying temperatures.

Now I don't know whether to get it or not.

Can anybody shed more insight here.

I hope to be putting my NANO in Wednesday. It is supposed to keep the bottle @ 1000 psi without heat, the NANO comes w/ a 4000psi charge. It is regulated to 1000 ish. I have yet to try it, but those that have swear by it for consistancy. I plan on running heater on the street and NANO for the track.

I should be picking up my brackets from the machine shop Tues, I had the NANO supplied brackets modified to bolt on to my Billet bracket.

 

sounds like a good concept, as long as you have enough nitrous capacity and a good regulator

wouldn't 2 bottles do the same thing for most?

 

Beer..........Exactly what are you getting ?

I am putting down about 400 rwhp without the 100 shot. I believe there are different systems for different horsepower.

I got the small one, I think its good to 300 shot.
Currently I am 417 ish at the wheels NA, plan on spraying anywhere from 100 Dry to a 200 Combined two stage Dry Wet...

Hoping to pick up my brackets from the machine shop today and start installing it.

 

If your venting liquid nitrogen to the atmosphere itwill always boil off at the same temperature. Its just the temp and pressure in the bottle that decreases. Its like boiling water at sea level It boils at 212 degress no matter how high you turn up the fire. It just boils off quicker.

 

Beer....The odds are good I will be getting NANO also.

I have a 2000 coupe and the 10# bottle is hidden in the well; I was hoping I could get the little NANO bottle in there also, so that everything is undercover; I don't know if there is enough room.

If you have any pictures or advise after the install I'd appreciate you sharing anything with me.

Despite being told this past Monday for the brackets being done, I got the truth out of the machine shop...their guy is out long term illness, so they subbed the bracket to another machine shop, and that guy went snowmobiling for a week...he comes back tommorrow, so MAYBE I will have my brackets in hand Friday

Wish we had good reliable and trustworthy machine shops/dyno/tuners here in Maine...

 

Took a while, finally got my modified brackets.

Need to swap out the 90 degree blowdown fitting for a 120 degree, and reroute the hoses/wire looms.

 

Ok, Beer99C5, can you splain how this works? I went to their website and they just tell you what the end result is, but not how they achieve it. I have a bunch of friends on N02 and they would love something like this if it truly works.

 

The NANO bottle has about 4000-4500 psi of compressed air or Nitrogen, you can fill them at a SCUBA or Paintball refill station.

The NANO head is basically a pressure regulator and is set for 1050 (I have not pressured mine up yet). Open the NANO and there is a constant 1050 PSI on the Nitrous bottle (you add a check valve to you N2O bottle on the 1/8 NPT bottle valve port). As your nitrous system is spraying, the regulator supposedly is maintaining a more constant pressure while your spaying, and reducing the pressure drop (as opposed to a heated bottle). Its similiar to a Nitrogen Push system, were the Nitrous is displaced with a higher pressure Nitrogen from another bottle.

I am gonna test it, I have Bottle pressure logging ability and dyno time available to play a bit with it doing some same jetting vs Heated vs NANO and the resulting RWHP, Unfortanately it will not be unil Mid/end April.

The beauty of this is no heating time, open the NANO and your ready to rock.

 

So does this mean that you're releasing the nitrogen from the 4klb bottle and drawing the nitrous out of the bottle as it passes the connection on the nitrous bottle to even the pressure out? Something like a siphoning effect?

 

The noid is closed, the nano bottle is opened, 1050 PSI overrides the check valve on the Nitrous bottle (cold full bottle 600-700 PSI), and the Nitrous bottle immediately goes to 1050 PSI.

The nitrous fires, with a regular heated system, your contents are released and you have to heat the the bottle up to get the pressure up.

With the NANO, the Nitrous used is displaced with more compressed gas, maintaining the pressure fairly constant during the run.

I would say its more a push vs Siphon effect. LOL but I went deck instead of engineering , so I may be wrong.

 

Beer is the NITROUS KING!

 

LOL nope far from it, cant wait to try it at the track though.

 

Well, Please start a new post and let us know how it works out as I am quite curious!

 

There is at least two vette guys using it on the LS1tech board they swear by it. I will post a new thread when I do the testing (be about six weeks) with graphs comparing jetting (start w/ 50 then 100, 125 Dry; and maybe a 150 and 175 combo Dry/Wet if the fuel system can cope).

Edit, here is a thread on LS1tech on some NANO gains (spraying way larger than I intend)

http://www.ls1tech.com/forums/showthread.php?t=879312

 

Anyone know how long the NANO bottle lasts versus the nitrous bottle?

 

Beer.....In your opinion, will everything fit into the well i.e. nitrous bottle, nano bottle and lines/fittings.
