Nitrous Oxide Boost for RC Engines

[Nitroaddict]

I never thought i would actually see it, but someone has done it. Amazing. Here are some pics of the system, along with a dyno graph showing the power gain.

If you go to www.jagrc.com they have some cool videos of it being used on a T-maxx2.5.Looks pretty Bad@$$.

hey - u look familiar, lol. yeah i saw them, its where i got this pics from

 

[RobH]

that's hillarious. Nitrous Oxide is no2 right? the same stuff they put in whipped cream containers right?

if so, i have some of those little nos containers at home. we have them to refill our whipped cream maker thing.

that is pretty sweet. and when did someone make an RC dyno?

 

[Nitroaddict]

rob - u are right on all fronts. i have no idea about the dyno - interesting though

 

[RobH]

this video is sweet:

NA, you are slippin. This has already been posted...I think, oh say, 10 years ago.

And I think r/c dynos have been around for quite a long time now. That's how all the magazines test the engines.

That video is kinda cool. I wonder how much you see of a difference. I mean I amy not be a brain surgeon but the graph does not look like too much of an improvement.

I have also made a dyno for my car just for misc. stuff.

How did you make a dyno?

Wow this kind of looks EXACTLY like this thread but this one was started quite a long time ago.

Well i should hae said a dyno without the electronics, oops

well not 10 years but about 8 months

When engine temperatures are so critical, NOS would seem to be very depermental to engine life. Instand speed but would it be worth the end cost in eaten up engine? I would have to doubt it.

 

[Rex2342]

I've talked to the guy who makes the kit on another forum and he has some pretty good explainations for the engine temp issue.He claims that the engine actually runs cooler with the NOS due to the increase in fuel pressure.

Hello everybody I am the Co Founder of JAG RC I thought I would answer some questions here. First off the bottles are similar to whip cream containers, extcept these have valves in the bottle so one it is opened it can be closed again. As far as the graph goes I think a 17.8% increase in RPM is pretty repectable, it takes a lot of HP to get a 17.8% increase! I would agree that temps are criticle, and even more so when your doing things like increasing RPM by nearly 10,000. When nitrous oxide is injected into the engine and finds it's way to the combustion chamber it breaks apart into nitrogen, and oxygen. This reaction is what is know as an endothermic reaction. What this means is when the reaction takes place it is actually using heat. So you inject an already cold gas, then you add an endothermic reaction on top of that. What we have found in our testing is our engine temps are 10-20 degrees cooler. Now I will tell you this is going to cause more engine wear than just running it. However any performance mod is going to cause more engine wear. That is just the nature of the beast! If you guys have any other questions for me please feel free to ask.

wow - thanks maxx - glad to see u here at RCNT! welcome to the club. other than the numerical performance gain - what is the physical performance gain? Can you see a dramatic spike in acceleration when the juice is turned on, or is it more subdued, something simliar to a good engine coming up onto the pipe?

 

[maxxheadroom]

I can tell you the videos do the kit no justice. The power gain is very noticable! BTW the maxx in the video is not a 2.5 the first video is with an M16 and the others are with a TRX Pro .15 anyway as soon as I can find somebody around here with a 2.5 I will be shooting a video of the TRX Pro .15 blowing the doors off the 2.5 with nitrous.

 

[RobH]

RCNT sure does bring in the big hitters. Someone posts a nitrous thread and the creator of the system joins the conversation! Now that's a forum!

maxx, i noticed the no2 bottles you have sport a fitting on the top. Did you have to fabricate the fitting to a normal bottle, or does some weird whipped cream product require a special bottle that has a fitting?

I can testify to the nos-temperature thing. We make whipped cream in this metal container. The container and the nos bottle start at room temp. When you release the nos in to the container, the outside of the contain gets super cold and you instantly have condensation and ice around the outside of it. That only be a good thing for engine temps.

This would be a bad-ass buggy mod. Wonder if it's race-legal.

 

[maxxheadroom]

The fitting on the bottles are a custom fitting just for this application. The cooling effect your talking about is the N2O going from a liquid to a gas state. The stuff is pretty cold isn't it? I run a 125HP shot of nitrous in my Mustang first time I pressurized my nitrous system I had a small leak. That little leak froze my carpet under it solid from only a couple of seconds of it leaking!

 

[maxxheadroom]

BTW Nitroaddict thanks for the welcome! I have been looking for a new home since maxxtraxx went down...

 

[maxxheadroom]

Also on another side note I did some quick number crunching. The car on the dyno would be traveling ruffly 77 MPH without nitrous, with the nitrous it would have jumped to 94.5mph and it would have reached that speed in less than 3 seconds! Can you say yee haw?
