Dyno Numbers with Nitro Methane
I did my oil analysis and the report showed nothing out of wack. Not enough solids to tell without previous samples to see trends. There was admittedly a little bit extra chrome, but this motor has over 200 K on it.
so whats your decision? you going to run it for racing and stuff? how much of a mix are you doing? any thoughts on spraying it from a H2o/meth sprayer?
I'm getting married in a month, can't afford to blow the motor. So no, I ain't gonna run it... till i get a real job anyway. Dyno was located in Spokane, Washington, my original hometown before college.
FYI: Call up Gillete Diesel, I bet they know of a few locals who own and operate them. On Thursday I was up at Larry H. Miller's oldest son Greg's home in Sandy and he has a buddy with a dyno. I'm sure if anyone has a bad diesel we could arrange a free dyno run.

Some info on Nitrometh from Wikipedia :
http://en.wikipedia.org/wiki/Nitromethane
The oxygen content of nitromethane enables it to burn with much less atmospheric oxygen in comparison to hydrocarbons such as gasoline:
14.6 kg of air are required to burn one kg of gasoline, but only 1.7 kg of air for one kg of nitromethane. Since an engine’s cylinder can only contain a limited amount of air on each stroke, 8.7 times more nitromethane than gasoline can be burned in one stroke. However, nitromethane has a lower energy density. Gasoline provides about 42-44 MJ/kg, nitromethane provides only 11.3 MJ/kg. This analysis indicates that nitromethane generates about 2.3 times the power of gasoline when combined with a given amount of oxygen.
Nitromethane has a laminar combustion velocity of approx. 0.5 m/s, somewhat higher than gasoline, thus making nitromethane suitable for high speed engines. It also has a somewhat higher flame temperature of about 2400 °C. The high heat of vaporisation of 0.56 MJ/kg together with the high fuel flow provides significant cooling of the incoming charge (about twice that of methanol), resulting in reasonably low temperatures. In a Top Fuel drag racing engine this alone will provide the cooling of the engine, as the cylinder heads are machined from solid pieces of aluminum billet with no water jackets.
Nitromethane is usually used with rich air/fuel mixtures. This is partly because nitromethane can provide power even in the absence of atmospheric oxygen, and also because nitromethane tends to produce severe knock and pre-ignition. Rich mixtures cause ignition problems and a lower combustion speed.
When rich air/fuel mixtures are used, hydrogen and carbon monoxide will be two of the combustion products, when these and any unburned fuel comes into contact with the oxygen in the atmosphere at the end of the exhaust pipes they often ignite. The result is spectacular flames from the exhaust system.

nice!!! that makes me want to try it more!
I know that Dr. Gas had a Dynotjet 248, but now Richard Madsen owns it. That was the only Dynojet I know of. Just trying to find one close...
Nitro Methane rocks!!! I think some of you guys with deep pockets should do some more testing. Or give me a donor, just in case, motor so I won't be without my daily driver when I reach the threshold of stupid... 51% nitro.
ok i just spent some time on the phone talking at lenght about nitro as additive. and we started talking about really big singles, and really big injectors and a big p pump. now figure in some nitro at a 20% or so mixture. it carries its on O2 so it should light the turbo much faster than regular #2. i really wished i had a dyno i could play on, i have a few spare motors.

Seriously though......would be interesting to see.......
any of you guys ever go to an nhra event and watch the top fuel cars and see what happens when the blower hicups (in a word BOOM really big fire ) theres nothing left but pieces to pick up still id love to be there when you all try it
Make a trip up here and we will make a weekend out of it.....we work with a shop up here that has a Mustang that im sure we can do whatever on......I just want to make sure i have the Lawn Chair, Beer and Video Camera ready......
Seriously though......would be interesting to see.......
