Dude7422

To actuate the solenoid, an on-off toggle switch is placed near the throttle linkage so that it is depressed when the throttle reaches 100%.

God I love the copy and paste function of these computers. Did you even read the the link that you provided us with I dint think you did.


CONCLUSION
THIS IS WHERE IT GETS GOOD

Additionally, the engine inevitably runs very lean during the nitrous shot as you introduce more oxygen without the ability to add a richer fuel setting, meaning that temperatures increase and wear and tear increases as well. We didn't have enough nitrous bottles to perform a long term test on our HPI truck engine, but during the 6-8 runs we did perform, the engine held up well and continued to run flawlessly when the nitrous was removed.

So there basically telling you that you have an overly lean condition. DO you understand how nitrous works. Nitrous is not flamable, it add's oxygen to the fuel that you have the more oxygen you have the more fuel you can burn. If there's no extra fuel to burn because the engine is already tuned for maximum performance then you get very little and I mean little preformance gain, you get an overly lean condition, your engine gets trashed in the long run, and if you do richen up the needles to get the performance you get sluggish preformance until you hit 100% full throttle. Then for 8 seconds you get maximum power, then after that you get crappy performance again.

So please read the links that you give use before you tell us how they work when you dont know how they work. As for the dee dee dee, I would make sure you know what your talking about before you use that again.

125 and that solenoid is why its 200 dee dee dee ...and are you not the same person that is always saying that nitrous & sc does not work well your wrong the dyno does not lie

and for the solenoid imo someone could use a small ball manual valve hooked to a 3rd servo and give small hits of nitrous you would not get the over lean problem 8sec is a long time for nitrous get it dee dee dee ONE MORE POINT AT ONE POINT IN TIME DIDN'T PEOPLE BELIVE THE WORLD WAS FLAT

RE: NITROUS EXPRESS SYSTEM
 

Thats because SC dont work, look you cant believe anything you want and which you will. Lokk at all the experts that dont use them. Dont you think if they worked all the pro drivers would be using them, but yet there not, you have to know how 2 strokes work to realise that a SC wont work. As for the nitrous I never said it wouldnt work, it will work. But listen to what I am saying before you post next time.

Ok here it goes are you listening. To get power out of this system you have to have your engine rich. Nitrous is not flamable it's an oxidiser which means it carry's it's own oxygen. Fuel does not carry it's own oxygen and fuel need oxygen to burn. Without the oxygen fuel doesnt burn right.

So when you add nitrous you need to add more fuel which means more power correct. Ok now that we have that down that you need to richen the needles up. Ok now that you have the needles richened up you will have more power when the nitrous is being used. But when the nitrous is not being used you have a really pig rich engine that doesnt want to perform like it otherwise would when you have it tuned for maximum performance.

So you eitherr let the needle setting go and have an over lean condition like the article that failed to fully read said, or you have a pig rich engine thats has no power until the nitrous is used. As for the dyno not lying well I never said it lied, you just have to look at the fact. Do you want a engine that explodes in 2 gallons or do you want a pig rich engine that dies prematurely becuase the engine temps are only at 180.

As sated I dont think you fully thought this idea through, and you didnt read the whole article like I DID. I just think you really understand how things work. But like the other thread I doubt that you will read this fully through so I expect another post just like you did. With no real reasoning behind it.

RE: NITROUS EXPRESS SYSTEM
 

125 the dyno graph shows the power thats all

RE: NITROUS EXPRESS SYSTEM
 

Did you read what I posted. I dont think you did read what I posted. And if you do read then post why I might be wrong about I say. Not just say well the dyno graph reads that you gained power and thats all.

RE: NITROUS EXPRESS SYSTEM
 

125 did or did you not post in the past that nitrous systems dont work ?? simple question
two pa dudes posting it out lol

RE: NITROUS EXPRESS SYSTEM
 

We have another form of racing that we do micro midgets and the one guy I know tryied nitrous in his engine. He said he felt no noticable difference in power, Thats what I said. I may have said that they did work in the way that they where setup. But never the less unless you set your engine pig rich, meaning that if you have your engine setup for maximum performance the way that it is it wont give any noticable performance. As the little fuel that is extra to burn wont give th epower that is neede to counter act the weight of everything that is neede to make it work.

So in a sence the way they want you to think it will work it doesnt work. Another words they want you to think you will hhave all this extra power while your enigne is set at maximum performance, but unless there is a way to get more fuel (like a wet shot on a 1:1 car) it wont gain any noticable performance like they want you to believe. Yes it will agin some power from the fuel that is left unburnt, but as sad the extra weight of this stuff will off set any gains.

You can believe what you want, but there are facts that need to be looked at, unless you run the engine pig rich (with no power until you get the nitrous to hit) you wont gain any performance from this application.

RE: NITROUS EXPRESS SYSTEM
 

125 why dont you have any photos of your rc cars in gallery here ???and your buddy that used nitrous maybe his nitrous shot was not large enough for what he was doing

RE: NITROUS EXPRESS SYSTEM
 

To end it all

4 channel radio & a very loose high speed needle that can be richened via a servo when a separate servo activates the nitrous...

Have fun doing everything at once though...

RE: NITROUS EXPRESS SYSTEM
 

lol sounds like a fix to the problem to me lol 125 needs to open his mind to new things and why didnt i think of that lol you know some fools is going to post about the 4 servos weight guess they never seen a micro

RE: NITROUS EXPRESS SYSTEM
 

Please read the whole post and not just some of it.

Why dont I have photos, I dont know, because I dont. Never really thought about doing it, and could care less about pics on my gallery. If you notice I dont have an avatar either, but that and the pics are not at the top of my list of things to do when I wake up in the morning. As some may know I have 1 xxx-nt with a O.S .18CVR in it. I have a xxx-t with a novak esc and a 11 turn Team Orion Rush motor on it along with a 27 turn P2K PRO Team Trinity motr with a 1500 stick pack to power them. I have 2 T-Maxx's, well actually one, the 2nd one it torn to bits and I use it as a parts truck really. There nothing special, as I'm not here to impress anybody, thats not my goal in life, I'm in this hobby to have fun and I know that if I post some pics like I have done other places then people start to say ohh well thats a crappy rc and mine's better like someone already has done to me in this site already. Thinking his rc10gt was way better then mine when he never even seen a pic of my truck. Some people just get a kick out of that I guess.

As for being in PA yeah thats cool. I live in the southern end of PA, I live in lancaster county and the town of maheim to be more exact. We are known for our football team and for the worlds largest Auto Auction. I played football and have wrestled. I also did karate and took some self defense classes with a ex-green beret, I went to school for sheet metal and did a lot of learning and made some great and not so great thing. I even tried making two exhaust pipes for my xxx-nt when I was doing some machining
(thats the not so great things that I tried to make LOL). There's my life story

As for the shot not being big enough I dont know maybe it wasnt I dont know the specifics. As for the 4 channel radio with a another servo. I didny really think about that but since you started the thread Dude7422 why dont you go ahead and show us this servo and how it will work out. Take care of the bugs then put a patent on it then go make the millions.

As for opening my mind I like to believe I have a pretty open mind as you have to, to be part of a race team and trying to be competitive. I'm am always trying to learn new things and try and learn from my mistakes.

But why would you need 4 servo's. One throttle/ brake servo one steering and the other (if you even try it) for the nitrous. As the link said they did like 6-8 runs and they couldnt do any test to see what the nitrous would do to the long term affect of the engine. As I said if you want to go ahead and do the nitrous I'm not stopping you just be prepared to have it run pig rich or lean as crap. Either one I dont like doing to my engine.

I'm not here trying to start a flame war, I'm really not. I'm just saying what will happen, if you can come up with ways to get around these problems then by all means do and and have fun. We are here to have fun so if nitrous will make you have a little more fun with your car then go ahead and do it by all means. I'm just here trying to warn you of what to problems to expect if you do get this product. But if eveything goes right for you (which I hope you the best ) then go have some fun with it.

Have fun with it and go kick some butt if it works, But I wouldnt expect the world of it and have it run short of your expectations. Believe me I know how that feels and I dont like that feeling, so I'm here just trying to give you a warning.

Peace Dude (no pun in tended)

I think this is what he is saying about servo controlled HSN, I dont intend to use it beacause its not race legal.

RE: NITROUS EXPRESS SYSTEM
 

I suppose the 4th servo would somehow control the hsn, so when the nitrous fires, it can richen the needle.
How about an auxiliary fuel cell that supplements the mixture when the system is activated?

RE: NITROUS EXPRESS SYSTEM
 

I would buy the kit to make a purge kit. I wouldn't actually use it in the motor. I would just put a 3rd servo on that would activate the purge. It would look bad @$$!

I have a 100 shot on my camaro. Works great, and I can't possibly see how a rc motor could benefit from nitrous due to the lack of nitro added. AND, nitrous has to be around 950 psi to work correctly. If pressure is too low, nitrous returns to a gas state (nitrous at proper pressure is in liquid form). I don't see how you could accuratly measure pressure of nitrous on an rc car. In my camaro, you can feel the difference between 800 psi and 950 psi.

The timing of your motor would also be thrown off since nitrous raises temprature, your glow plug would probably heat up quicker advancing your timing (the opposite of what you want to happen with nitrous) and you would loose performance there also.

I love nitrous, it just doesn't make sense why you would use it in an rc car.

RE: NITROUS EXPRESS SYSTEM
 

heh , how about a servo that both leans the hsn and shoots the nitrous... no engine damage there, after abit of trial and error maybe...
also, i think the amount of lube that enters the engine doesnt decrease when your shooting the nitrous, its just that fuel like never gets 100% combusted in any engine, which is where nitrous comes in, but then again im no good with nitro engines...acheiving a higher % of fuel burnt in the cylinder somehow makes the engine get less lubricated?

::edit:: i think its kind of cute tho, tuning your needles via servos on the go..... even if its not race legal maybe people can just make a mount for the servo on the chassis so they dont have to keep on driving back to wrench on their cars,just keep adding clicks on the radio until the engine sounds just about right... but a 4 channel radio might be abit expensive tho....

RE: NITROUS EXPRESS SYSTEM
 

I dont know maybe you guys may like the Nitrous thought but I know I wount be putting it on any of my rc's any time soon. I still dont see the purpose, I guess it's kinda like the Super Chargers and the wow factor I guess. Even though it will hurt your engine I guess people are still willing to put it on there. I still think a new engine that offers that power all the time instead of a 8 second burst of power is better. Not to include all of this mounting crap that is needed, all the weight of this stuff (how heavy is it) and all the complications with this nitrous system.

For $200 I would get another engine and a tuned pipe thats offers that power all the time instead of 8 seconds. And another though, so lest say you get this thing and slap it on. You hit the nitrous and it last's 8 seconds, then you want to hit it again so you pull it over, and it takes what 2-3-4-5 minutes to put this thing back in for 8 seconds. I could see that being annoying as crap after about 2 or 3 runs, but hey I guess if you want this thing bad enough you will get through this. All I know is even if this thing was $20 I still wouldnt get this thing.

RE: NITROUS EXPRESS SYSTEM
 

125cc people that drag race well love this yes its not for everyone just a few

RE: NITROUS EXPRESS SYSTEM
 

who cares if theres no room or you could buy a better engine, its NITROUS IN AN RC CAR!!!!!!!! it dosent have to be value for money or perfectly fitted.

RE: NITROUS EXPRESS SYSTEM
 

also, like... once you use up a bottle of nitrous, how much is it to buy a new bottle?

and yeah i think that remotely richening the engine is the only way to go to use this nitro thing, the nitrous feed alone isnt enough

RE: NITROUS EXPRESS SYSTEM
 

no drag racers dont, they have ported 40 sized boat motors running like 60% nitro, guess they know best, no?

RE: NITROUS EXPRESS SYSTEM
 

This is right.

Out of all of the drag racers I have seen they have used larger engine's and used high nitro contents. So people that race wont love this, and another question for you. When you do this extra sevo how will this mount and the thing that I see going wrong with this is, well some engine's are really touch with there needles. So a few degree drop will mean you will have to retune, will you be taking off the servo every time you need to adjust the needles, and when you do adjust the needles you will need to adjust the servo to match up with the newly adjusted needle.


As for the question of how expensive the new bottles are, it said in the link I believe they sell new bottles for $4 a piece. As I said it's just not worth the money that need's to be spent on it. For some yes maybe it's justified, but to most it just wont be. As I said I cant justify buying it for 8 seconds of power for $200 when a new tuned pipe will do the same for 1/4 the price.

RE: NITROUS EXPRESS SYSTEM
 

125 the price was 4 from nitrous express but you can buy the refills from cake makers at 75 cents each any one do the math on how much a single 75 cc tank of nitro cost 25.00 a gal. its just for kicks hahahah and for 125 for all the drag racers dont use this dee dee dee its new no one has done this man your funny

RE: NITROUS EXPRESS SYSTEM
 

i dont get it, why cant you use the servo to tune the engine... is it like because the servo wont turn it far enough or something

RE: NITROUS EXPRESS SYSTEM
 

No carmatic, its because the tuning is a very fine adjustment you really need a hman to do it.

Haha i aid nitrous instead of nitro back there, this threads getting to me :)

RE: NITROUS EXPRESS SYSTEM
 

no way they are not that fussy imo a ((((((caveman)))))) could do it tune a motor his come back will be my nova rossi is lol bad joke
