Alternitive to nos? Have an idea and a ?

[nedlynitro]

First off my question is how much of a difference is there for adjustments on the engine when using 20% nitro and 30% nitro? I had an idea last night, maybe an alternative to nos?? Say your engine was adjusted right so you could run either 20% or 30%, i run 20%, so for me with my idea, i would fill the tank with 20%, and fill another either regular tank or smaller tank with 30%, and instead of a nos injection, just have a 30% injection, most say nos is a pain, gimmick, causes problems, well why not just have an injection of a better fuel? Run 20% around the track and before you hit that big jump, have the truck inject 30% into the lines...I'm sure it would take some modification, design and creativity to make it work, if it would even work, i figure where there is a will there is a way, so designing it and making is not the issue, i need to know if it is possible when it comes to adjusting the engine between the two fuels, let me know what you think if this is a promising project i may do it and tell everyone how it goes!!:whhooo:

Or...maybe an injection of pure nitromethane?? I found that you can buy a gallon of pure nitromethane, maybe a small injection of that would be a good nos alternative..??

It could be done but that is a lot of work for a small gain as switching between 20% and 30% doesn't yield massive changes in power, only a small one. The main thing to consider is you would need to be able to adjust your tune on the fly, you can use a remote needle which would take up your third channel (if you have one) Then you would need control over the switching between two tanks, this could be done with a pressure switch that is activated at WOT, if you wanted to manually control all the workings in the truck you may need a new radio with multiple channels so you could operate each feature separately from the remote. As I said, it's a lot of work for minimal gains but the cool factor would be there.

Yeah i have most everything i need, but outside of just switching from 20% to 30% what about just injecting 100% pure nitromethane into the lines?? check out the link ^^^^http://www.klotzwarehouse.com/index.php?productID=8640

if i were to make it so it injected 100% nitromethane, i would design it to mix the nitromethane with the nitro fuel when injected, so that it was not just the nitromethane but would be nitro fuel with more of a ratio like 40+ percent fuel???

As mentioned above, giving your mill a shot of 30% would yield very little difference in power. If you gave your engine a shot of pure nitromethane I'm quite confident it would both rev well beyond it's engineered limit and also become underlubricated at those extreme revs. More than likely you'll throw a rod. I am however just hypothesizing.

My bad, I just skimmed your post and didn't see the comment about mixing it. You could simply inject some high percentage boat fuel. Some types of blends made for boats have as much as 60% or so nitromethane.

 

[nedlynitro]

Yeah i had wondered about exactly that, if i were to create this, it would inject very little ntromethane into the fuel line, and would be a small injection, for the temporary boost, i would simply flip the injection on and off so it would give it that spit, but then go back to regular fuel....just an idea but liking all the advise keep it comng i may try it i have an engine that is almost no good if i do it i will try it on that engine and make vids for everyone!!!

 

[racendad6]

this is kinda off topic but does anyone bore the 3.3 motors and maybe do like a stroker kit?

 

[nedlynitro]

i can't help you there i know nothing about that....

 

[w bill]

If you really wana have some fun dont even think of playing with that just go to a nos system things will get movin the nos gives you the most power for your dollar!:

 

[Extreme RC Mods]

You would have to be able to control the HSN as a higher % of nitro would require a more rich setting. The next thing is how would you meter the nitro so you know what mixture you have, like mentioned adding "dry" fuel to the mix would lower the % of lubrication of the overall mixture, this is bad. Another thing to think about is compression and head clearance, jumping up the nitro will probably require an additional shim which would not work the best when running the regular fuel. I'm not trying to be negative, these are just things that one should think about because it's not as simple as you would think, at least to get the setup right.

You can't bore these engines out, they are a tapered fit piston with a brass sleeve and chrome plating, if you remove the chrome by boring it out the engine would not run.

A real nitrous shot does nothing but destroy the engine, there is no way to increase the fuel flow for the correct air/fuel ratio which would lean the engine to very dangerous levels.

The supercharger will not work either due to design flaws of the unit itself.

The best way to increase power and rpm is a good tuned pipe or a porting job or both, I can do both. The other option is to just get a bigger engine.

 

[nedlynitro]

Thanks! I don't take it as negative, i take it as advice and wisdom! so don't worry about shooting me down thats why i started the thread to see what people thought, and so far you have been a great help! Just had to throw the idea out there

 

[w bill]

Extreme is right on the best way to increase power except with the nos there is away to enrich fuel mixture it gets very complicated it involves a second spraybar and a miniture solinoid gets pricey but can be done ! Yes nos is hard on an engine!

 

[alpinehyperlite]

so you are basicly saying NOS is good? Really? No.......

 

[Extreme RC Mods]

You can't just bolt in NOS in a 1:1 and hit the button can you? there has to be some sort of computer controlled addition of extra fuel so it wouldn't lean right out. There is no way to confirm what mixture you have after the NOS starts to flow so I'm not sure it wouldn't just smoke and seize the engine. Yes you can rig it up and dump a shot into it but your tune will be a crap shoot at best.

 

[nedlynitro]

I seen a good vid with nos, and when he wacked it flames came out the exhaust and it took off like a model rocket, but I'm almost positive the engne was fried after that haha

 

[frickenjoey]

NOS in an "RC engine" Apline...not so well really. You and I both know the gains it makes in 1:1 scale engines. I have seen and done it. Note to self... 150hp+ shot is bad.....hmmm
Nedly.... Robin (RC Extreme Mods) really knows what he is talking about when it comes to RC engines. His pipes are fantastic. I have one on my LRP .30 and it makes crazy power. I would rather have a Picco P3 ported out by Robin but I will deal with what I have.

 

[Extreme RC Mods]

Thanks Joey, I'm happy you like the pipe, it's good to hear that it works well with the LRP .30 also. I haven't heard of an engine yet that didn't wake up and make more power and rpm with one. That's excellent.

 

[nedlynitro]

I took a look at them pipes and trust me i have already decided to try one once i get my big block I'm sure once i get that going i will be plenty satisfied and forget all about nos haha

Hey extreme, i had a hard time finding some products on the web page that I'm looking for maybe you can help, I'm looking for piston/sleve kits for 2.5 engine and 2.5r engine for a price quote, if you have something good ill order it from the extreme mods definitely!

 

[Extreme RC Mods]

I'm not sure if you mean my web page (site) I don't stock many parts, I'm just a modding business that sells modified engines or work on engines that are sent in. Along with the pipes I am looking into tube roll cages, stainless fuel tanks among other things. Here are a couple links for the parts your looking for, sorry I can't provide them for you.

I would do the bearings while your at it, if they let go the new parts will probably get trashed.

[nedlynitro]

Yeah i have seen those kits, just looking for the best product for the best deal, and yes i have the bearings just down to piston and sleeve, do you do mods on 2.5? Like what could you do to it, the engine i run now I'm happy with for a while, but i have an old 2.5 that is an original, the ugly looking ones if you know what i mean, if there was some cool mods you could do to it that i could afford, i would mail it in see you work your magic

 

[Extreme RC Mods]

I don't mod engines that are much past break-in, it's not cost effective for you. If you want the newer one done up, I change the factory timing to be more aggressive which results in more power and rpm. The only question is can the engine take the extra forces, they don't seem to have a great track record even in stock form. This is a risk that you take when modding sport level engines, some last a very long time, some don't.
