Finding a Few More Horses for your MINI Cooper

With the modifications to the engine that were suggested in Section 2, it is possible to bring the engine’s power to well over 200 horsepower. But there’s more where that came from, if you’re looking for more performance.
By getting deeper into the engine, we can bring the car up to as much as 300 horsepower, and add more torque in the rpm mid-range, adding to the car’s performance off the line, when overtaking other cars, and getting out of the corners. Horsepower-enhancing aftermarket parts include a plasma booster for spark plug performance, spark plug wires to take advantage of the stronger spark, an upgraded throttle body, a hotter cam shaft, and an improved cylinder head, as well as silicone hoses to improve reliability,.

Plasma Booster Ignition Upgrade
The intensity of the spark that is delivered to the cylinder by the spark determines how efficiently the air/fuel mixture in the cylinder will be ignited. The efficiency of the ignition in turn affects the engine’s power output, mileage, and smoothness of operation.
A simple “black box” can be added to the ignition system to achieve these benefits. Called a Plasma Booster, it is a power amplifier that increases the power of the primary and secondary spark circuit by nearly 100 percent to deliver a much “hotter” (more powerful) spark to the cylinder. A more powerful spark will ignite the air/fuel mixture more easily, and cause the mixture to burn more quickly. The result is more power from the fuel, more efficient use of fuel, and more consistent power from each individual firing for smoother engine operation.
Individual measurements before and after the addition of the plasma booster indicate an additional four horsepower from the engine, and ten percent better fuel economy. The Plasma Booster costs about $270, and can be added to the engine in just a few minutes without any special tools. As a nice plus, it is certified for use in MINIs by the California Air Resources Board because of its benefits in reduced emissions and better fuel mileage.
