TECH BONUS – BIG ENERGY/BIG WIRES
by Todd Ryden
There are a number of advantages to running coil-per-cylinder ignition systems, which is exactly why you see them on every new engine rolling off the assembly lines. With today’s advanced technology, the ignition timing can be controlled to match the fuel delivery in each cylinder to result in the best performance. Thanks to advanced drivetrain management capabilities in motorsports, these advantages are being pushed to the extreme.
To keep pace with the high voltage needs of racers, the team at MSD have always been pushing the ignition envelope with new products. One of their latest systems, the Smart Coil Big Wire Kit offers a number of different advantages that we’ll dwell on for a bit, (you’ll get our pun shortly.)
But first, let’s answer the two most common question about this new coil-per-cylinder performance ignition coil set: What exactly is a Smart Coil and how does increasing dwell time affect spark output?
To understand the intelligence level of coils, we need to review a coil’s function …
