Spark Plug Wires Spark plug wires have two main objectives; transfer the spark energy to the plugs and suppress the Electro Magnetic Interference (EMI) that the spark voltage projects. Too high of resistance decreases the spark energy, yet too low of resistance may generate too much EMI noise which will interfere with the operation of other electronics on the vehicle. A good quality wire, proper routing and routine inspection are all important in getting the most performance out of your... (more)

The Fuel Can Test There's been no shortage of well-researched and well-written articles and books explaining the workings of the fuel system. However, many racers, both novice and experienced alike do not fully understand the physics of fuel flow and horsepower. To produce torque and horsepower requires a mixture of air and fuel. To produce 1-horsepower for 1-hour requires approximately .5-lbs of gasoline. If you ran a single-cylinder engine, like the one in your lawnmower, under a load of... (more)
