Engineering Design Competition

Do you enjoy designing things?

Do you enjoy racing CO2 dragsters? If so, this competition is for you! Come join Grace College’s Engineering Department for an afternoon of drag racing and fun coming soon!

For this competition, participants will be tasked with designing their very own CO2 dragster to race against others in their division. Rules and requirements for designing a dragster are located below. There will be two divisions: one for high school students and an open division for other individuals. Entry for high school students is free and $25 for individuals in the open division. High school students have the opportunity to compete for scholarships and the winner of the open division will receive a cash prize!

Students will also have the opportunity to interact with local industry members.

*Rules and Registration are located below.

Are there prizes?

CO2 Dragster Rules

You will be designing a CO2 dragster to race against others in your division. We want you to get creative, so there are no restrictions on how you go about machining your car or what material you use. Feel free to paint your car, put stickers on it, etc. However, your design must meet ALL requirements below: 

    • Lego Driver/Cockpit 
      • Your car will be “driven” by a Lego minifigure, so you will need to make a cockpit for them to sit in
      • The Lego driver must stay in the car the entire duration of the race and be able to see (as if it were a real driver). If the Lego driver falls out of the car during the race, this will be considered a failed attempt
      • Lego drivers may be attached to the car using any means necessary (glue, Lego baseplate, etc.), but they must be in a seated position (not laying down)
      • You must supply your own Lego driver
    • Weight
      • The minimum weight of the car (including the Lego driver), must be 100g
    • Overall Dimensions
      • Length: must be at least 260mm long and no longer than 320mm
      • Width: must have a minimum width of 8mm in all sections, maximum width of 100mm
      • Height: must not be taller than 100mm in any section
    • Axles (To purchase axles – pitsco)
      • There must be a minimum thickness of 4mm of material around the axle holes
    • Wheels  (To purchase wheels – pitsco)
      • You must have 4 wheels on your car and they must all touch the ground
      • All 4 wheels must be perpendicular to the track (neutral camber required)
      • The front wheels must be 34mm in diameter and the back wheels must be 40mm in diameter
      • The minimum width of the front wheels is 3mm and the back wheels must be at least twice as wide as the front wheels
      • The minimum thickness of any part of the wheels is 2mm
    • Co2 cartridge mounting requirements (see picture below)
      • The CO2 canister chamber must be a cylindrical hole 20mm in diameter and 51mm deep
      • The canister chamber must be parallel to the ground and the longitude axis of the car
      • The center of the canister chamber must be 20-40mm from the ground
      • There must be a minimum thickness of 4mm of material around the canister chamber
      • We will supply the CO2 cartridges for the races
  • Eyelet mounting requirements
    • The car will be secured to the race track with an elastic line that passes through two eyelet screws on the bottom of the car (see picture below)
    • Two 4mm eyelet screws must be centered on the width of the bottom of the car and be at least 100mm apart
  • General restrictions
    • No internal or external power supply (except the CO2 cartridge provided) 
    • No extra gas 
    • No additional actuators 
    • No combustibles 
    • No mechanisms for interfering with other people’s cars 
    • No modifying the CO2 cartridge
