NANO: Nitrogen Assisted Nitrous oxide

[LXtasy]

I stumbled across this today on nitrousforum.com and it actually peaked my interest. Has anyone seen this in person or maybe ran it themselves?
It seems like a good idea.

i have spent a few days with the owners of NANO during Drag Week this year. the theory behind the system is that the nitrous will have a precise amount of pressure during the whole run. we did some testing but cant say if it really did anything. we made some passes to the 330 mark. this was on a 1100 hp engine that had 2 foggers on it. Monte Smith (www.montesmithperformance.com) was also there during this testing. Monte is nitrous tech for NOS. Monte may have done some more testing and would be the person to contact.

Thanks. I understand the theory behind it. Some people are claiming a 4mph increase and a alittle bit lower et with it. But unsure what long term effects it may have on the engine.
I can get nitrogen refills all day long through work. It would be nice to use every bit of nitrous up.

if anything, i think it would help and be more consistant. thats what its supposed to accomplish. it could make you lazy about checking your bottle. takes the danger out of bottle heaters. nano gave us a special compressor to fill are own bottles.

nano guys were trying to convince Monte that fuel pressure would need to a certain % higher. monte wasnt buying it but tested their theory anyway. according to MONTE plug swere rich during the test but we were running the fuel pressure around 9*. plugs didnt look bad to the naked eye but according to Monte looking thru one of those spark plug checkers he siad it was rich. i just tried to keep my mouth shut and take orders from Monte on what to do to the car.the NANO guys were great and very helpfull but we were just running out of time and had to lay a number down so we pulled the NANO, heated a full bottle and set fuel pressures back down to a leaner but safe tune

I have read where people are actually upping their fuel pills to compensate. That is weird he said it was running rich. See, stuff like that makes me wonder.

yes, he said it was rich but keep in mind that fuel pressure was at 9! with the NANO system. with out the NANO we ran 6 lbs on first gun and 5 on second gun. also, you have to keep in mind that we were only testing 330 ft, where the NANO system really shines would be after that, would the plugs still read rich on a full pass, i dont know. but testing a 7 sec car on full passes is alot of work so we started out with 330 passes and ran out of time because of other crap. we were going to test NANO all week but the whole week turned into a cluster phuck

I always wondered if some manufacturer out there would ever offer a 2 stage pressure regulator for a nitrous system to keep nitrous output pressure constant for the duration of a run.

Simply have a bottle that can hold 2200 psi like all other gas cylinders at welding supply stores and regulate it down to a constant 900-1100 psi. You would even be able to make more runs on a bottle charge, too. Sounds like a winner to me compared to your bottle pressure diminishing during a run.

Anybody know how much nitrous pressure is needed to keep the nitrous in a liquid state all the way up to the solenoids? I say just engineer a system that keeps nitrous pressure regulated just above this liquid state pressure and you might be able to get even more run time from a bottle. Of course the fuel side will have to be calibrated to this new pressure, too.

I wonder if a constant pressure nitrous system will eliminate the typical 2nd half of the 1/4 mile falloff as compared to how supercharged and turbo cars run on the 2nd half.

Then again, maybe I just think too much.

thats exactly what the NANO system does. nitrogen assisted nitrous oxide

I have sold a few nano kits and know people with them. It works great if your not running alot of nitrous or changing bottles all the time.
I hope your not getting any tech advice from that guys webpage, thats all I'll say about that.

No I am not lorenz. I was just skimming around over there and came across that. Sparked my interest mainly

One concern I have about this system is how much are you diluting the chemical make-up of the nitrous oxide. While nitrous is primarily made up of nitrogen, you may be causing the whole mix to fractionate. Just like blended refirgerants can do. Also what happens when your nitrous bottle runs out, do you just get plain nitrogen to your engine? Sounds like a disaster waiting to happen to me. Anyone out there in the HVAC service world like me will understand what I'm saying.

I'm with Gerald on this one. Design a bottle that can stand 2000+ psig and regulate it for a constant pressure!

Yeah, the straight nitrogen part has me concerned if it is in the same vessel as the nitrous. I have messed with liquid nitrogen at work to assemble interference fit parts in lieu of using a press. Liquid nitrogen stays liquid for quite a while at atmospheric pressure. If enough of this were to get in your engine, you may risk a hydrolock situation giving you bent rods and/or blown head gaskets.

Now if the nitrogen is used in an accumulator, which uses a bladder or an isolation piston to keep it separate from the nitrous, I can see how that would be a safe design to try to keep nitrous pressure more constant than just taking it straight from a supply bottle.
