Where to get nitromethane

You need huge fuel-side solenoids with special internal orifices capable of handling thick, viscous, lacquer-like nitromethane-probably at least two 0. Applied Nitrous Technology specializes in hard-core systems for just about every race venue; as owner Jeff Prock puts it, "We've put nitrous on everything from model cars and lawn mowers up to Fuelers. The goal was to prevent dropped cylinders induced by ignition that had trouble lighting off the percent loads of nitromethane. It was hoped that nitrous would speed the flame front, which would permit retarding ignition timing, reducing ignition stress.

Expectations were met: instead of 65 degrees, the engine ran best at 50 with nitrous. The nitrous jet sizes were roughly the size used on a hp system for gasoline car, with eight 0. Fuel flow at 6, rpm had been Times plummeted from 5. The big problem was shredding clutches. Stark reports that the engine combo was never optimized for nitrous oxide: "We would have taken out some compression ratio if we kept pursuing it.

High compression isn't needed with all that oxygen and fuel-you just want max volume of fuel into the cylinder. On the other hand, another nitromethane combo running 0. Several explanations are offered for the phenomenon of flames shooting out the exhaust pipes. Gene Adams says it's due to superchargers that "blow through unburned fuel on overlap. According to Adams, more volume means longer flames. Now it's more like 10 feet. An alternative explanation is that not all the nitro has the time to ignite within the engine and goes out the exhaust, where it ignites on contact with atmospheric oxygen, burning with a characteristic yellow flame.

If a rich mixture has entered a monopropellant phase, hydrogen and carbon monoxide are produced as a byproduct. Bright white flames are then generated by burning hydrogen. Initial start-up with high nitro concentrations is very tricky. Jeff Prock says, "You must get the engine cycling.

It won't start up spinning at rpm like a gas engine would. You need to get some heat in the engine and spin it at 1, to 2, rpm. The common practice is to start and warm up the engine on gas or alcohol. High percentages of nitro required massive breakthroughs in ignition technology. Today's top-of-the-line MSD units put out 50, volts and 44 amps on the top end. That's about the output of an arc welder at each cylinder-and the Fuelers run two of them.

Once you get a nitro engine going, it may not want to stop. At 7, rpm on the top end, there's so much heat in the engine it may keep running under autoignition even if you shut off the magnetos.

Essentially, it becomes a diesel. Fuelers today shut down by turning off the fuel pumps as well as the ignition. Correctly lending nitro involves far more than a mixing cup. The specific gravity SG of fuels varies per batch and purity; methanol's out-of-the-barrel concentration can vary 5 percent or so.

The by-weight mixture is also dependent upon temperature, both during the initial mix as well as if the temperature changes afterward. As temperature rises, the weight as measured by SG decreases. For tuning, it's the percentage by weight that's important, so it is necessary to mix the fuel using a hydrometer and keep track of mixture temperature. Gene Adams, one of the old masters, offers some tidbits:.

At high rpm, there's just too much volume of fuel and not enough time to burn it all. A blown alcohol dragster with a screw-compressor supercharger will run to 10, to 10, rpm; normally aspirated nitro cars in the same class run around 6, rpm and they make about the same power. If you try to rev them up higher, the power falls off.

Adding a supercharger allows the engine to rev up higher, to about 8, on the top end. Keeping everything together is, so we build things stouter-bigger piston wrist pins and heavier cranks, for example. Aluminum rods are obviously lighter than steel rods, but we use them for shock resistance, not weight savings. The T6 billet aluminum rods are much larger physically, so they are physically as strong as a mild-steel rod-but you can't keep bearings in a steel rod.

This works better under nitro's tremendous loads. There's also a tremendous amount of blow-by even when running good, due to the tremendous internal pressure and rich fuel mixtures. There's a lot of cylinder-wall wash-down. Typically we use a Dykes top ring with a 0. Normally aspirated with modern race gas or methanol, compression ratios are typical.

With nitro, you're looking at about 10 to A blown motor might run 6. The ports are so huge you can put your legs in the heads. Valves sizes are 2. That's not as radical as a Pro Stock car or alcohol dragster, but we don't turn the rpm, so why sacrifice durability? With so much ignition lead, excessive duration would only increase blow-through anyway. The cams are single-pattern because Hemis are not exhaust-side limited. Popularly, nitro is considered a "slow-burning" fuel, but the burn rate is between gas and methanol.

The problem is that on high end, nitro-fueled engines, only about 10 percent of the fuel in the chamber is vapor when the burn starts; the rest is liquid. StrangerGuy Diamond Member. May 9, 8, Originally posted by: BrownTown hes trying to get an organic solvent to remove superglue apparently.

Which randomly gets me on another funny story about a teacher of mine who was found reading the communist manifesto in high school during cold war obviously , and the FBI actually DID come to the school because he argued with his history teacher about what it said even thouhg she hadn't even read it of it.

Also, randomly I have also read the Communist Manefesto its a good book. I just though I'd say that since the FBI is probably already reading this thread. Aug 23, 25, Super Walmart. Aquaman Lifer. Dec 17, 25, 2 0.
