Instructions

• 1). Increase your engine's displacement. Doing so allows for more gas to burn during each revolution of the engine, thus increasing the power of the engine. You can do this either by making the cylinders bigger or by adding more cylinders. Twelve cylinders is generally considered the practical limit of cylinders, but you should seek your mechanic's opinion.
  
  
• 2). Increase the engine's compression ratio. By compressing the concentration of air and fuel, your engine will become more powerful. Be careful with this one because the more you compress the air and fuel, the more likely it is to burst into flames before the spark plug ignites it. Again, ask an experienced mechanic's opinion on the maximum compression ratio your engine will safely allow. High performance cars generally have higher compression ratios, so they use high-octane gas that's less likely to ignite spontaneously.
  
  
• 3). Consider purchasing superchargers or turbochargers and adding them to the engine. These pressurize the air and fuel so that more can be rammed into the cylinders, thus making the engine more powerful. This is essentially an alternative to increasing the size of the cylinder or adding more cylinders and the outcome is basically the same. Choose turbochargers or superchargers that are equipped with an intercooler, a special radiator that cools the air entering the cylinder so that it is more likely to expand.
  
  
• 4). Inject fuel into the engine. Fuel injection improves engine performance and fuel economy by metering the fuel into each cylinder more precisely.
  
  
• 5). Replace heavy parts with lighter parts where possible, especially the pistons. Each time a piston uses a certain amount of energy it has to change directions. A lighter piston requires less energy than a heavier one.
