Found this interesting read regarding the use of nitromethane with aux injection systems. It's about 10 pages long, but has some interesting information for those of you that like to read stuff like this. Personally I would be reluctant to run it with our engines, but it looks like there is at least some HP potential there. It would also be rather expensive to run much of it.

Someone was curious as to what nitromethane was in Fast and Furious 4 was . "Nitromethane is for pussies"

I believe the biggest problem with running nitro (at least solely nitromethane) with the rotary is that nitromethane has a very long, sustained burning period compared to gasoline/methanol, and with the amount of overlap in any decently ported engine, you would not see the full benefits of the fuel.

 

you talking about pure nitromethane or radio control car mixes of methanol with 10-20% nitromethane and some oil?

 

Im thinkin we need to reopen this idea. The link above is not functioning. ive been thinkin of the option of 60%nitro 40 Alky. I think the main problem... Beyond the long burn time..... Is the fact that it burns very very hot. And im a bit concerned about the actual rotor housings melting. Please i need a new link if anyone has seen any info on either sprayin or running as a fuel.

 

like any uncharted territory, some ones gotta start some where,

if the burn period is long would that heat push the turbo faster,or longer, and harder Damifino

 

and gotta be somthin to it, DRAG racing banned it back in 1951(except for nitro classes only).
and they only mixed it with gasoline, and run it thru a carburator. ( some guys actually took the carb jets out completly to richen up things)

sounds like exciting to me!

 

Nitro carries more oxygen content then most if not all other types of fuels. Thus, it would produce the most horsepower. The cost of this stuff is out the window though. If it wasnt for that, Id consider running it.

 

Okay so this what i know bout Nitro. The burn rate is way slow. Hence the reason we see golden rods of fire in Nitro class NHRA cars. Gas burns "perfectly" at 14.7:1, Alky burns "perfectly" at 7:1ish. Nitro burns "perfectly" at 1.3:1. This means obviously that u can stuff almost 13 times more fuel in one power stroke with nitro as u can with Gas. Awesome right? sure if u like goin into hydro lock alot of the time. Also Fuel dragsters only run on Spark ignition half the run. the rest is What we would consider "dieseling." She runs on pure fire and heat build up. He in lies the real problem im seeing..... Our rotor housings are aluminium. The temps inside a fuel drag engine are well above 2000 degrees inside the chambers. now yes... the pistons and head are both Aluminium but they are a lot thicker then our housings. Aluminium melts at 1400 degrees. This is also the reason I was thinking running a mixture. Kinda like a Blown ProMod runs. BTW the last time i checked Nitro fuel prices.... This is for 99.99% Nitromethane..... It was at $25ish a gallon. This was 3 Years ago. Also as i stated before. Seens how u puttin 13 times more fuel in the motor im sure u can imagine the fuel system needs to be a bit outta control large. Also Nitro and Alky is corrosive. So yeah theres a lot to think about. So....... Does Anyone know if Anyone has tried any sort of nitro in our motors? Hope some of this sheds some light on nitro.

 

Just an FYI, on the nitro cars (as in, the cars that run "fully" on nitro), they burn all they can, and then detonate the rest of it, which is why it cackles. I'd think detonation + apex seals =

There aren't many other ways to get all the useful power out of the fuel, due to it's slow burn rates.

FWIW, I've grown up with, and worked crew on, a 10x World Championship Top Fuel (nitro) Motorcycle team, so take that for whatever it's worth.

YUP! but gotta start somewhere, and then you can be ahead of the curve.

just think of the learnin curve, compared to everyone else.

in the old days guys just tried things,till they made it work, new guys dont have that old guy *****, they afraid of hurtin there toys.

Don Garlits made about 1500hp in 1958, using stock Chrysler junk yard engines, and dumpped all the nitro he could into it, as long as it run clean and smooth

 

I'm pretty sure a few puerto ricans are already running/playing with nitro.

 

I'm not saying it can't be done... I'm just saying nitro is very hard on parts due to it's nature.

Piston engines can take the detonation; another thing to remember, T/F cars make 1 pass per engine. Our bike(s) may make 3-4, at most, before a full rebuild is warranted. That will get expensive, if you're replacing housings every 3-4 passes.

 

never said it was gonna be easy or cheap, but what if you blew everybody right off the track.

thats the basis for all competition.

you can peck around on little changes that still cost a fortune of money or bite the bullet, and move ahead.

 

digitalsolo is correct. friend of mine tried it messed up engine and turbo.....and he was just using an injection kit

 

any idea on what kind of quantity he was injecting?

 

i dont know how much but i dont think it was that much, what we spoke about is that we dont think the parts, like seals, turbine blade are strong enough to withstand the heat. just our two cents. i'll find out exactly how much. i have a gallon of the mix for rc cars and afraid to use it bcaz of what happened to him. when i have a spare motor then i'll try some ****

 

i run a chevy v8 , on 30% Nitro and 70% methanol, and it knocked a full second off ET at 1/4mile, back in 1965, using a hilborn mechanical injection, in a dragster car.

Yes i think it can make power.

 

I'd hate to dig up a dead thread but to prove its possible to anyone who read this thread.
