CO2 dragsters are cars used as miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 metres) track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, and aerodynamics.

How does carbon dioxide racing work?
In this type of racing, the participant builds a small carbon dioxide cartridge into the car, which propels it down a flat, level track. They're fast, too -- on a 65.5-foot (20-meter) track, the cars can cross the finish line in just over a second, traveling at nearly 70 miles per hour (112.7 kilometers per hour)!
What are CO2 racers?
Fortunately, there is a type of racing out there that could be described as the "Pinewood Derby on steroids" -- CO2 racers, which are also small, wooden racecars where a propulsion system has been added. In this type of racing, the participant builds a small carbon dioxide cartridge into the car, which propels it down a flat, level track.
How does a CO2 dragster work?
CO2 Dragster. Dragsters that use CO2 as a propellant move when CO2 is escaping rapidly from the cartridge that is placed in the car. The placement is such that the gas escapes in a rearward fashion. Because Newton's Third Law of Motion is in practice the car moves forward, overcoming any resistance in the process.
How do you put a CO2 cartridge in a car?
Add your CO2 cartridge into the hole at the back of your car. Make sure the hole is not punctured in any way, or the cartridge will explode. Lastly, add your fish hooks. These are encouraged, but necessary, for your car. If you are running a race in a track that has a string for the car to follow, these are perfect for staying on the string.

Every gallon of gasoline burned creates about 8,887 grams of CO2.
At what RPM do turbos kick in?
between 80,000 and 200,000 rotations per minuteIn order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that's up to 30 times faster than most car engines can go.
What happens if you run too much boost?
Increasing boost (within reason) will force more air into the engine, so more fuel can be added to increase the power. So in general, if you add more boost and have an engine tuned to suit will give you more power. Too much boost can cause turbo or engine failure.
Does cold weather affect turbo boost?
As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
How much CO2 do race cars emit?
Each gallon burned emits about 20 pounds (9 kilograms) of carbon dioxide, so that's about 120,000 pounds (54,431 kilograms) of CO2 for a race weekend [source: FuelEconomy]. Multiply that by roughly 35 races per year, and NASCAR's annual carbon footprint is in the area of 4 million pounds (1.8 million kilograms).
What is the fastest CO2 dragster?
On the 15th October 1997, at Black Rock, Nevada USA, Andy Green piloted the Trust SSC (SuperSonic Car) and achieved what was previously thought impossible. He travelled at a speed of 1,227.985 km/h (Mach 1.020) and broke the sound barrier.

Pinewood Derby racers don't have engines, but instead use gravity to pull them down a small track on which several cars compete against one another. The idea behind the derby is to design the most aerodynamic and properly weighted car possible.
What is a CO2 cartridge?
The CO2 cartridge is a small, metal cylinder filled with carbon dioxide that has been highly pressurized and sealed. At the flick of a button -- we'll learn how they're launched in a minute -- the gas is released, propelling the dragster forward. Advertisement.
What is the engine of a Pinewood Derby?
While a Pinewood Derby car is simply put on a downward-sloping track and released, CO2 dragsters have agents of propulsion that launch them forward in a (hopefully) straight line on a level track. The "engine" that propels the tiny car in this case is a carbon dioxide cartridge, also known as a soda bulb. The CO2 cartridge is a small, metal ...
Can you build dragsters for science?
Whether it's for a science class or just for fun, many hobby shops and Web sites sell tracks to race them on, timers and other tools to make building and racing dragsters easier. Keep in mind that building these fast little cars can be just as addicting as any kind of racing -- but on a much smaller budget.
Step 1: Create Design
To create my design, I used CorelDraw x3. I drew my design with different lines, making sure to keep it symmetrical.
Step 2: Print Design and Cut
I then laser printed my design on the wood, I used a saw to cut it out. (Freehand drawing is also fine).
Step 3: Drill Holes
Then I drilled holes for where my axels and CO2 cartridge would be. Also above, I put in small pieces of straw to block the wood and axel from hitting each other. Putting graphite in the straw is also helpful to make the wheels turn smoothly. (Graphite is not necessary for your car).
Step 4: Add Axels
Put axels inside of cut straw. You will need to cut the axels down so they are slightly sticking out of the car. (Front axel is an example of the axel being too long, back axel is correct size.)
Step 6: Add Wheels
Add the larger wheels to the back, and the smaller wheels to the front. The axel will go inside of the hole in the wheel.
Step 7: Add CO2 Cartridge, and GO!
Add your CO2 cartridge into the hole at the back of your car. Make sure the hole is not punctured in any way, or the cartridge will explode. Lastly, add your fish hooks. These are encouraged, but necessary, for your car. If you are running a race in a track that has a string for the car to follow, these are perfect for staying on the string.
Step 8: Ask Questions!
If you have any questions about this project, feel free to ask me. Also, if you have a good project that you are working on, I would love to see it. I am always looking for new projects to work on! :)

Most of the twin turbo drag cars I've seen were set up this way, with turbos placed where headlights normally would be, or directly in the grille with a cutout.
Do you have to cool methanol cars?
Most of those cars are on methanol now anyway so there's no need to cool it.
Does Alky keep the motor cool?
Yup. About everyone now has switched to alky for fuel, the days of VP c16 and q16 are gone. Just not cost effective. We ran an air to water on our mustang back in the 2000. The intercooler was welded to the aluminum Kirkey pass seat and the well tank in the rear cooled it. The alky keeps the motor cool but all that boost puts the air inlet temps through the roof.
What fuel is used in drag racing?
There is nitro-methane fuel, which is used mainly in drag racing to produce huge amounts of horsepower.
Where is the cooler on a race engine?
Typically, at the left of the engine there is a spherical tank for the cooling liquid. As you can imagine, race engines reach higher temperatures than coming engines, so a better cooler is required. It's very similar to computer overclocking, if you're familiar with this: the higher is the clock aimed, the better should is the cooler and the components of the main board.
What happens if you crash with liquid nitrogen?
Ditto with materials in the car and their safety. During a crash leaked liquid nitrogen is going to put most HDPE and PP thermoplastics used in cars below their glass transition temperatures, making them more brittle. Car steel might also lose strength at low temperatures. And as anyone who's ever worked with liquid nitrogen before knows, both the heat absorber and the exhaust gas will be very very cold, and cause billowing clouds of condensed water vapor to flow from a liquid nitrogen car.
Why is nitrogen used in fuel?
Nitromethane is usually used with rich air–fuel mixtures because it provides power even in the absence of atmospheric oxygen.
Can you use liquid nitrogen as fuel in a race car?
Talking about liquid nitrogen, it might be used in race cars but not as fuel. We know boiling point of liquid nitrogen is very low. Hence it can be used as a coolant as race car engines generate lot of heat. But I am not sure about it.
Is nitrogen better than dust off?
Also, if you were going to to that, nitrogen would be a poor choice. The stuff in cans of “dust off” would be much better, because it will expand more & not require as much insulation to store

Why is CO2 bad?
CO2 systems originally and overtime got a bad rap because they were accompanied with off brand, and cheap fittings and line. NOT ALL FITTINGS AND LINE WERE CREATED EQUAL. Some are not rated to hold a temperature that is up to the task of the under hood heat of a boosted car. Others leak before any environmental effects are pushed on to them.
Why do you need to do the same thing every time to tune a vehicle?
Because the launch boost is only a portion of equation. To tune a vehicle you need repeatability, you need it to do the same thing everytime to minimize variables. Because CO2 Can raise and lower basically on demand. When you plot a boost control graph with CO2 you can count on the targets being hit.
