The following is the basic set of Blastcar Rules as established by the Bouy Scouts of America. Local troops are free to alter the rules to fit their particular needs. Blastcar rules may differ from one troop to another. Please check your local troop rules before building your Blastcar.
BSA Blastcar Rules
Boy Scouts only may participate in a BSA Blastcar event. Additional participants may be included in the event only at the discretion of the troop.
The Blastcar Rules state that the car must be built from the materials in the Official Boy Scouts of America Blastcar Kit. Only official BSA Blastcar axles and wheels may be used.
Additional weight may be added to the car. Decorative items may be added to the car.
Blastcars built in previous years are not allowed. A new car is to be built from the Official BSA Blastcar kit.
The total overall length must not exceed 10˝. The eyelets must have ¼˝ clearance to the course surface.
The total weight of the Blastcar without the Co2 cartridge must be no less than 5 oz. Any added weight must be solid in form and everything must be firmly attached to the racer. Liquid or moveable weight is not allowed.
Blastcar Rules Axle Placement
The axles may be placed anywhere on the Blastcar body. No wheelbase restrictions.
Only graphite or other dry lubricants are permitted. Oils or liquids are not allowed. Blastcar Rules allows the scout to re-lubricate the car between heats and in the designated areas.
Items Not Allowed
Springs, bushings, wheel bearings and washers are not permitted. The Blastcar must be freewheeling with no type of propulsion other than a single Co2 cartridge.
Each Blastcar must pass the pre-race inspection by the event judge on the day of or the evening prior to the event. The judge has the right to disqualify any car that does not meet the outlined criteria. Cars are checked in, given a race number, and entered on the heat schedule.
Blastcar Event Attendance
The Scout must be present at the location of the event to enter his Blastcar in the event. Each Scout is responsible for placing his car on the race line, inserting the CO2 canister, and then backing his car into the launcher.
Blastcar Rules Sportsmanship
Blastcar Rules are established to create a fun and sportsmanlike environment. Poor sportsmanship will result in disqualification of the Boy Scout. Boy Scouts are expected to be dignified whether winning or losing.
Blastcar Race Event: HOW TO GET STARTED…
Ok… so you have decided to put on a Blastcar race event for your Boy Scout Troop. Congratulations. This will be one of the most exciting events of the year for your scouts. They will have a chance to test their engineering and building skills in an attempt to build a cool looking and fast machine. A Blastcar race will be a very fun and super exciting event for all of your scouts and their family. So let’s do this!
But wait a minute… first things first. Forming an Event Committee is priority one. You shouldn’t take on this entire process yourself. The purpose of the committee is to help you plan the date, time, length, and courses for your troop’s Blastcar Race Event. The committee members should include scouts, troop leaders and perhaps a few eager parents.
The following items are a few of the things that should be taken into careful consideration by the committee.
How much time to allow
The number of different Blastcar courses selected and the number of heats run on each course will determine the time needed for the event.
Blastcar Race Course
What type of course will we race on?
Are you going to hold the race inside?
You can race on a gym floor, carpeted room or covered patio or pavilion.
What is the length of the course?
The course, or track, length can range from 50 to 75 feet.
Will you race outside?
You can use a smooth parking lot, basketball court or loose dirt playground.
What kind of terrain is available?
You can race for speed only on a smooth flat or inclined surface or you can build an off-road course for an ATV event. An off-road course must be straight but can include varying terrain like dirt, sand, gravel, snow, mud, etc… your imagination is your only limit.
Blastcar Race Fuel
How many CO2 Fuel Canisters will you need?
Estimate the number of CO2 cartridges needed for the event by multiplying the number of racers by the number of heats; factor in 10% extra canisters for re-runs.
Custom design your own race course or create multiple course options based on time and terrain. Then design a car that will be launched with CO2 fuel canisters. Engineer your car to master a single course or go for the ultimate challenge and design an all-course winner!
Blastcar Race Safety Messages

For race day supplies and equipment and more information on how to conduct a Balstcar race event contact your local scout shop.
Blastcar BSA is here to Stay!
Blastcar BSA is a brand new racing event designed exclusivley for Boy Scouts and its flat out full speed fun.
The scout starts with a block of wood. He develops a design that will be aerodynamic and super fast. He can then test and tweak the car in order to reach its optimal design for speed.
After testing, he will sand and paint to give the car a sleek and smooth finish.
Events can be designed for top speeds on a smooth track or designed for endurance on an off-road corse consuisting of obstacles including rock, dirt gravel and mudholes.
Blastcars are fueled by CO2. CO2 canisters are steel cylinders filled with compressed CO2 fuel. The CO2 is removed from the air at the factory and then released at the race event—no new CO2 is created or added to the atmosphere. This is called a ‘zero’ event. Blastcar cars are designed using principles outlined previously.
The launcher kit has the base launcher, start – finish plates, and 50# test line for tethered head-to-head racing. Set up is easy and fun. Races may be run on a variety of courses. This Blastcar BSA launcher is safe, accurate, and easy to use. Innovative, full-feature design adjusts high and low to accept cars of varying shapes and sizes and allow synchronized starting of any two car designs. Exclusive daisy-chain feature allows multiple launchers to be linked together for synchronized starting of four or more cars.
Blastcar BSA may be eventually be a more exciting event than the Pinewood Derby. If Blastcar BSA enjoys a fraction of the popularity as the derby it will no doubt be a huge success and a part of Boy Scouts for many years to come.
Embedding Graphite into Blastcar Axles.
The better lubricated your Blastcar axles are the faster your racer will blast down the track. The idea is to reduce as much friction as possible. The better lubricated the axle shaft the less friction there will be. That’s no mystery.
The mystery is… Are you lubricating your Blastcar axles well enough?
Most Blastcar builders use graphite for lubrication. Most builders lube the insde of the wheel bores, insert the axles, spin the wheels a few time, and their done. You can take that technique to the next level by embedding the graphite into the axle shaft.
It doesn’t matter how well you polish your Blastcar axles… there will always be minute scratches and pits on the axle surface. Instead of ignoring those blemishes… builders are better served if they pack those blemishes with graphite. Some Blastcar experts only lightly polish their axles so that many fine scratches and pits remain. They believe that the many blemishes will hold more graphite and provide better and longer lasting lubrication.
Not just any graphite will work well with the embedding technique. The individual graphite particles must be minute in order to embed themselves into the metal of the axle. The graphite should be no greater than 325 mesh in order to achieve the best results.
The best way to achieve this is after you have polished your Blastcar axles. Then place an axle in a drill press. Tighten the chuck just enough to hold the axle. Avoid over tightening because this may damage the axle screw threads. Cut a polishing cloth or extra fine sandpaper into 1/4″ wide strips. Rub a liberal amount of graphite into a strip. While the axle is spinning in the drill, apply the strip to the shaft for about 15 seconds. Repeat this process if needed. This fills the microscopic scratches and creates a micro-thin graphite film on the axle shaft.
This additional amount of lubrication can help propel your Blastcar to victory lane.
Blastcar Racing Boy Scouts. The all new Blastcar™ racing activity is a merit-badge-driven activity intended for Boy Scouts. Scouts can earn a merit badge while at the same time enjoy a Pinewood Derby type competition like they enjoyed as Cub Scouts.
New Blastcar Racing Boy Scouts can develop their knowledge to experience the engineering design process through sketching an idea for their Blastcar, laying out a design, building the car, conducting trial tests, modifying their design, and adding finishing details. Scouts design their cars for optimum performance on the courses they’ve engineered as a team.
The Blastcar Racing Boy Scouts can compete against each other scouts on the specially designed Blastcar race track. The cars are powered by compressed air in the form of an 8 gram CO2 cartridge and guided by a 50 to 75 ft cable which is usually a 50 pound test fishing line. A starting device is used so that the cars are ignited at exactly the same time.
The present Blastcars and components are designed for speed. However, the inside information indicates that the BSA will soon introduce special off-road type wheels for Balstcar ATV racing. The scouts will design their own off-road course using sand, gravel, mud, etc. Then race their cars through the obstacles to determine which scout has designed the optimal off-road blaster.
Blastcar racing is a super exciting venue that has been needed for a long time. Finally, older scouts can enjoy a racing competition and dads are no longer forced into Pinewood Derby withdrawals. This is surely a great tool in convincing Webelos to continue into scouting by getting involved with Boy Scouts. Blastcar Racing Boy Scouts will also be excellent recruiters as they explain the benefits and fun of joining scouts.
