How do I choose the right turbo size?
Turbo selection depends on engine size, boost target, rpm range and desired response. A smaller turbo spools faster; a larger turbo supports more top-end power.
Why is wastegate placement important?
Poor placement or sizing can cause boost creep or unstable boost control.
What are the benefits of the dual ceramic ball bearing system in the Pulsar 7975G turbos?
The dual ceramic ball bearing system in the Pulsar 7975G turbos enhances turbo response by reducing shaft movement, which leads to quicker spool times and improved durability. This design helps maintain stability under high boost conditions, making it suitable for both street and race applications.
What are the recommended oil feed and drain specifications for the Pulsar 7975G turbos?
For the Pulsar 7975G turbos, an oil feed flange of -4AN is recommended, using a non-restricted standard T4 flange. The oil drain should be -12AN, and the kit includes an O-ring sealed flange to ensure a secure connection and prevent leaks.
What is the significance of the anti-surge ported-shroud compressor inlet in these turbos?
The anti-surge ported-shroud compressor inlet design in the Pulsar 7975G turbos helps to reduce the risk of compressor surge, which can occur during rapid throttle changes. This feature allows for smoother airflow and improved performance, particularly in high-demand situations.
What is the expected power range for the Pulsar 7975G turbos, and what factors influence this?
The Pulsar 7975G turbos are rated for up to 1450HP, but actual power output will depend on several factors including engine setup, tuning, fuel quality, boost levels, and RPM. Proper installation and matching with the engine's characteristics are crucial for achieving optimal performance.
What are the dimensions of the compressor and turbine wheels in the Pulsar 7975G turbos?
The compressor wheel in the Pulsar 7975G turbos measures 79mm x 91mm, while the turbine wheel measures 82mm x 75mm. These dimensions are designed to provide a balance of airflow and boost response, making them suitable for high-performance applications.
