Ceramic coating piston, Nitriding crank and rod?

[Theblaze1987]

One more question. What is the best % nitro to run in a trx 3.3. What do you run in a picco .28. Can I run 30% in the 3.3? What is the highest you could use? If the engine was modded with a stronger crank and rod could I use higher then 30%? I don't mind breaking stuff money is not to much of a issue for me, I like pushing things to their limits and having fun and doing stuff that has not been done before. But I want it to be benificial atleast for a little bit, not just blow up on starting.

Yeah close to 4hp in a rc car seems crazy awesome!

I have an airplane engine on my t-maxx, and it goes 200 + mph!

It's powered by peas, and yes I'm joking.

A picco .28 or similar high output bb will easily show you the limitations of a revo.

The Picco was made to take the power. I run 30% in everything I own with no problems at all. That is about as high as you want to go with land based vehicles really.. unless, you start mixing your own then that is a whole new headache. The 3.3 is just fine with 30%....I would step down from a hot plug to a med. temp plug though. I run cold in most of my bigblocks.

Hey 2Revo...you still have the solar panel on it too?....lol

Of course I do! Gotta have some downforce!

Can anyone tell me a good rc mag to sign up for geared towards modding?

Converting 3.3 to diesel?

Hey guys is there any performance gains in converting a nitro engine to diesel? Do they produce more bottom end torque? doesn't converting to diesel limit the rpm's significantly?

 

[frickenjoey]

Kinda pointless. Not a true diesel...you have to use a "special" diesel and it ends up no cheaper just harder to get fuel for. If it was a good idea i would have done it years ago. I wish it was as easy as that.

 

[Theblaze1987]

Yeah I know you still have to buy their expensive diesel still because you need the lubricant still. So there are no performance gains? It's just more of a bragging rigt thing then?

 

[frickenjoey]

Yeah no perfrmance gains just being able to say you have something differnt. I'll just burn nitro.

 

[Rolex]

No performance gained. All these engines have been engineered for a specific use whether it's MTs, on road, airplanes, helis or boats.
If there were a sure fire way to make them better, a manufacturer would do it just to sell it.

 

[MudSlinger33]

They already are diesels, seeing as heat from the compression ignites the fuel.

 

[Theblaze1987]

Has anyone ever thought about doing some ceramic coating to the piston in your nitro engine or having the crank hardened with the Nitriding process like they do in full size race car engines?

 

[frickenjoey]

Problem is where to get it done and would the tolorances be close enough to keep from destroying the engine?

 

[Theblaze1987]

Yes I have contacted several companies to see ifthey can work on something this small, and I am waiting to hear back. The problem is going to be exactly what you mentioned and that is in the tolerances sine the coatings can add several hundredths of an inch and that is a huge deal in this engines that are extremely small as it is. But I think it's worth looking into. On rb mods.com they sell costume aluminum cranks for your trx 3.3 so maybe you could have a custom steel crank made with the tolerances several hundredths of a inch to small to compensate for the coating? Also I was thinking about looking into thermal displacement coatings for the heatsink. Although I know it is a good thing for the engine to run in the 200 degree area could this also be of any benefit? Also coating the header in ceramic?

 

[frickenjoey]

Most of this is a good idea in therory but you will spend way more money than any gains you will get.

If it's not an RBI unit,how about a link to the video of the specific one you are asking about?

 

[Theblaze1987]

Let's say theretically I was able to get this done, and beefed up engine components, what my theory was, was then possible the engine crank rod and piston would be strong enough to run 40-50% nitro which is where the power gains would actually come from. Still sound good in theory? More nitro= more power?

 

[Theblaze1987]

Unfortunately I am on my iPhone and it does not allow mr to copy and paste a link to a YouTube video. But I believe maybe the difference is that possible these dragsters are 1/4 scale so they are running gas engines which is why they van run superchargers. So I have found after reading numerous threads that a supercharger is pointless on a 2 stroke, but they do benefit on a 4 stroke correct?

 

[Racer 1966]

Several hundredths? That ain't gonna work here.

All that stuff is a big waste of $$$ for this hobby IMO. That's the kind of things that need done where you're racing with limits/restictions on engine sizes and mods. A well modded engine that's tuned properly is all you'll need for r/c.

 

[Theblaze1987]

Yes I understand you can not be off on engine specs even .001, so my point is you would costum order your crank .002 smaller to compensate for the coating which adds .002 of an inch. My point is just trying to get the absolute most out of a engine like the picco .28 and perhaps beefing it up enough to run 40% nitro through it

I see what you mean about Doug stuff like that when in a class that restricts engine size though. I was just wondering if anyone else has thought of coating the internal before.
