Everyone wants more horsepower. In a car like a Miata and in a racing class like Spec Miata – the differences are small. Every little bit counts–sometimes it might only result in a single HP increase for a particular change. The Miata can lose up to 20% of the engine power through the drivetrain. Changes here can make all the difference. How do you know which changes affect your horsepower? By testing on a dyno.
