Nitromethane with Methanol?

In for info

found these bits of info

"The energy content of gasoline is ~18,000 BTU/pound while nitro has ~5,000 BTU/pound. By pumping in 8.7 times as much nitromethane per stroke, you get about 2.5 times more power per stroke. "

"after nitromethane is burned it produces large amounts of nitric acid, which is not only corrosive but toxic."

As far as mixing...
"If you are running methanol, there is no problem as nitromethane and methanol mix freely."

Also curious about some of the "hobby fuels" as an additive.

I can not believe that no one has played with nitrometh :chicken:

I have been wondering this for years now, and i believe no one in the supra community has experimented with it.

Guess Im'ma have to be the first to blow my shit up then.. :rofl:

Don't waste your time, seriously.... There are better ways of getting an extra 30-50hp than mixing nitro in your gas tank or injection system.
Even cars on alky don't see any real performance gain until they reach a 30%mix, and it's illegal to use in 99% of the classes out there.

Turn up the boost 2-3psi, put a better exhaust on your car, better cams, 2 degrees more timing, etc etc to gain 30-50hp extra...

While youre at it, put a small bottle of Hydrazine in the mix also

this interests me because i am a chemistry major in college right now, and have been talking to my teacher about my car and made sure he had a understanding on how gas is burned w\under boost and octane and everyrthing, and needless to say he knows alot about it. so i am kinda teaming up with him when i get my car running to see if there is anything that i can inject that will help me out. i dont want to release any info on this because i might be on to something with this. i just cant wait to get my motor abck together and try this idea he has.

have any of you priced what nitro cost/gallon? LOL....and people think import is expensive

prepare to shit yourself.....

OT but a good read:


dunno if this a repost... search turned up nothing.
Top Fuel Facts...

--------------------------------------------------------------------------------

Some real cool facts about top fuel dragsters I stumbled across.....

---------
* One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona.

* Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume.

* The supercharger takes more power to drive than a stock hemi makes.

* Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition. Cylinders run on the verge of hydraulic lock.

* Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

* At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitromethane measures 7050 degrees F.

* Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.

* Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression-plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting off its fuel flow.

* If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or blow the block in half.

* Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons.

* To exceed 300mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.

* If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second.

* Dragsters reach over 300 miles per hour before you have read this sentence.

Did you know …

… that the nitromethane-powered engines of NHRA Top Fuel dragsters and Funny Cars produce approximately 7,000 horsepower, about 37 times that of the average street car?

… that one cylinder of the eight cylinders of a Top Fuel dragster or a Funny Car produces 750 horsepower, equaling the entire horsepower output of a NASCAR engine?

… that the gasoline-powered engines of NHRA Pro Stock cars produce about 1,200 horsepower, about eight times that of the average street car or equivalent to one 47-88 Supra.

… that an NHRA Top Fuel dragster accelerates from 0 to 100 mph in less than .8-second, almost 11 seconds quicker than it takes a production Porsche 911 Turbo to reach the same speed?

… that an NHRA Top Fuel dragster leaves the starting line with a force nearly five times that of gravity, the same force of the space shuttle when it leaves the launching pad at Cape Canaveral?

… that an NHRA Funny Car is slowed by a reverse force more than seven times that of gravity when both parachutes deploy simultaneously?

… that NHRA Top Fuel dragsters and Funny Cars consume between four and five gallons of fuel during a quarter-mile run, which is equivalent to between 16 and 20 gallons per mile?

… that NHRA Top Fuel dragsters and Funny Cars use between 10 and 12 gallons of fuel for a complete pass, including the burnout, backup to the starting line, and quarter-mile run?

… that NHRA Top Fuel dragsters and Funny Cars travel the length of more than four football fields in less than five seconds?

… that NHRA Top Fuel dragsters can exceed 280 mph in just 660 feet?

… that from a standing start, NHRA Top Fuel dragsters accelerate faster than a jumbo jet, a fighter jet, and a Formula One race car?

… that a fuel pump for an NHRA Top Fuel dragster and Funny Car delivers 65 gallons of fuel per minute, equivalent to eight bathroom showers running at the same time?

… that the fuel-line pressure for NHRA Top Fuel dragsters and Funny Cars is between 400 and 500 pounds, about 20 times greater than the pressure on passenger-car fuel pumps?

… that depending on size and angle, the large rear wing on an NHRA Top Fuel dragster develops between 4,000 and 8,000 pounds of downforce?

… that the 17-inch rear tires used on NHRA Top Fuel dragsters and Funny Cars wear out after four to six runs, or about two miles? Some brands of passenger-car tires are guaranteed for 80,000 miles.

… that it takes just 15/100ths of a second for all 7,000 horsepower of an NHRA Top Fuel dragster engine to reach the rear wheels?

… that it's desirable for an NHRA Top Fuel dragster to race with its front wheels inches off the ground for about the first 200 feet of the run? This ensures proper weight transfer to the rear wheels, a crucial part of a good launch and quick run.

… that the nitromethane used to power the engines of NHRA Top Fuel dragsters and Funny Cars costs about $30 per gallon?

Nitro Booster™ is a great power adder designed for use with gasoline engines using Boost Cooler™ water-methanol injection kits. A proprietary blend of nitro methane and a specially developed emulsifier that keeps Nitro Booster™ equally distributed in the water-methanol mixture. This allows for a small percentage of nitro methane to be injected into the engine in the correct proportion with air and fuel to produce impressive increases in power. Usually, around 30 to 50hp increase can be measured. Nitro methane has fewer BTUs than gasoline, but contains oxygen and acts like a chemical supercharger and an octane enhancer to safely increase power.

If this works, why has no one tried it?

in to hear if someone has used.

If no one has tried it... i will see if its any good this summer.
Gotta install the meth kit first:fruit:

You looked under my hood?

Ive been in the pits before at a major funny car even in colorado a few years back and the only tank I seen was a small 1 gal at the front/right area of the motor. Definitely didnt see a damn 5 gal tank or whatever it is.

heh, believe it or not, they don't melt park plugs on every run. I spent the whole day last time Top_Fuel was here hovering around the pits asking questions. I had a couple different teams give me old spark plugs from the previous runs for me to look at. Most of them still looked pretty new. One of the techs from Force's team said usually they don't melt, he says when the tune is on, they usually comes out looking fairly fresh, but here and there they will have cracked or missing porcelin when they are pulled out.. They actually recycle engine parts, after a pass everything is pulled from the block and set aside, then a whole fresh set of everything is put back in. After this the old parts are all inspected and measured, if they are still within tolerance, they are put back into circulation. Seemed like most teams had 3-6 complete sets of everything. There may have been more, but just from what I could tell from sneakin around ... Usually if they don't blow anything up on a pass, they can resuse the parts multiple times, but they always get pulled and inspected before being put back into circulation.

Pretty neat stuff.
