The Mazda RX-7, particularly the FD generation, is renowned for its lightweight design and exceptional handling. However, many enthusiasts aim to push the limits of its performance, striving for 500+ horsepower. This article delves into the best forced induction packages available for the FD RX-7 and examines their real-world performance outcomes.
Understanding the FD RX-7’s Engine
The FD RX-7 is powered by the 13B rotary engine, which is known for its unique design and high-revving capabilities. To achieve significant power gains, forced induction is often required. Let’s explore the options available.
Types of Forced Induction
- Turbocharging
- Supercharging
Turbocharging
Turbocharging is the most popular method for increasing horsepower in the FD RX-7. By using exhaust gases to spin a turbine, a turbocharger compresses incoming air, allowing for more fuel to be burned and thus increasing power output.
Supercharging
Supercharging, on the other hand, is driven directly by the engine’s crankshaft. This method provides immediate power without the lag often associated with turbochargers, making it an attractive option for some drivers.
