Ive always wondered what would happen if you mixed in a lil bit of nitro methane in with your fuel?? Just curious

 

I dunno, why don't you try a little and let us know?

 

Throw a gallon or two in the tank and get back to us with the results.

I would say if you mixed it just right you could get it to light in the IP

 

Your pyro wouldn't react fast enough to show you the 4000° EGT before it melted-- along with everything else. At least on straight nitro.

This is one where the risk/reward seems unfavorable from the get-go.

I guess the lowdown is that none of us really have any idea what would happen at low concentrations, but it sounds terribly dangerous to your engine. I've personally never heard of nitro being used in a compression ignition engine, only spark ignited engines. I don't know whether that means anything or not...

 

I'm sure in moderation it would probably work well....don't ask me what the mixing ratio would be, though!

 

Compression ignition engines is where nitro works best!! Cylinder pressure typically is far too high for spark plugs to work at all when using nitro in higher concentrations - just look at top fuel and funny car nitro engines - they don't even use the ignition system at WOT....the plugs are destroyed at the end of a pass anyway. Glow engines in RC models are all compression ignition engines and run on a mix of nitro and methanol not unlike nitro drag cars.

 

On another site I just read that there is diesel race fuel and that the DHRA has a stipulation for it. One of the posters responded that yes there is and it is a 2% concentration of nitro/meth.

 

I remember a guy who used a combination of alky/nitro as his fuel enrichement in his nitrous setup. He was/is a famous engine builder. Don't remember his name. He ran 10's in a Chevelle, I believe, and did it for several hundred thousand miles running a ton of spray and abuse. He credited the longevity of the engine to the use of the nitro as a fuel enhancement due to it's high deterance to detonation... Don't know how that would help in this thread, but I thought it was a good story...
btw- this was back when 10's in a street car was unheard of....

 

I've got a really crazy friend with a Dmax who ran nitromethane in his watermeth. When I say crazy, I mean CRAZY. He has an 05 with only 18K on it and he's already had various fueling boxes on it, he gets them from the dealer that warranties any breakage by the way... tell me how that works! Anyway, back to the nitromethane, he ran it and said it gave a bit more kick than the water methanol. I heard him take off with it in and it just sounds really weird, it sounds almost like a straight piped gasser. He doesn't run it anymore, he just had some laying around. He says he'd rather run nitrous. He's got a blue bottle sitting on a shelf in his garage right now, he is just trying to find a cheap way to plumb it himself. So the nitromethane can be done, and no it didn't melt anything down. He didn't say anything about the temps so I don't know if it got hotter or not? Did I mention the truck only has 18K on it?!!!!!!!!!! I wish I had that kind of dough!

 

A 5 gallon jug of pure Nitromethane online is $225.50. Not including shipping & hazmat.

CTD Nut,

I was going to say "***" fuel is nitromethane and those engines are like little diesels.You said it best.

 

I used to be into rc stuff big time. The old guy that owned the shop had competed with planes and boats at the national level for years. Every gallon of the nitro fuel that he sold, got a couple of ounces of castor bean oil added to it. When asked why, he claimed it added extra lubricity to the fuel, keeping his customers from destroying motors if they got a little lean.
Any body ever tried castor bean oil in a diesel?

 

A couple MORE ounces of castor oil??? That's been the main lube ingredient of model glow engine fuel for a gazillion years anyway...

There's supposedly a story from WW-1 that the 2cycle rotary biplane engines used castor oil in the fuel/oil mix. The castor oil vapor/fog from the exhaust could get so bad that breathing so much of the stuff would give the poor pilots "the runs"...
