Yes, that's the one. Napier wanted to keep the size of the engine small, so the supercharger packaging was very, very tight. All of the intakes lay flush with the contours of the G6 aircraft, no scoops. One was on the outside of the cylinder block cowl, one between the cowls and one underneath. The airflow into each was completely different, especially when the aircraft was banking and turning, and the lower one sucked in a large amount of spray on take-off, which damaged the impeller blades. Gloster tried a number intake scoops, but none solved the problem completely, but they did manage to take the air speed record before loosing it to the Supermarine S6 just one day later.
Free of the intake issues, when fitted to Bluebird and Miss Britain III, the engine performed perfectly and took world speed records with ease.
