KraftWerks 30MM Boost Upgrade Supercharger Pulley
2013–2016 Scion FR-S / 2013–2020 Subaru BRZ / 2017–2020 Toyota 86
159-99-903C
Overview:
The KraftWerks 30MM Boost Upgrade is a high-performance supercharger pulley designed to increase boost pressure by approximately 3 PSI over the base KraftWerks supercharger kit. Engineered specifically for the Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020), this upgrade enhances the already impressive power delivery of the KraftWerks Rotrex supercharger system.
Ideal for enthusiasts seeking more aggressive power gains without sacrificing drivability, this pulley upgrade helps your vehicle deliver stronger, broader torque and horsepower across the entire powerband. Whether you drive on the street or the track, the 30MM Boost Upgrade offers a reliable and efficient way to elevate your car’s performance.
Key Features:
This pulley upgrade builds on the advanced technology of the KraftWerks supercharger system, providing enhanced boost and improved throttle response. Key features include:
- Precision-engineered 30MM supercharger pulley designed to increase boost pressure by approximately +3 PSI from the base kit
- Compatible with KraftWerks Rotrex traction-drive supercharger systems for Scion FR-S, Subaru BRZ, and Toyota 86 models
- Lightweight, durable construction to maintain system reliability and reduce rotational inertia
- Enables higher shaft speeds exceeding 200,000 rpm for superior transient response and efficiency
- Designed to deliver broad, usable power gains across the entire RPM range for street and track use
- Maintains the quieter, cooler operation characteristic of the patented Rotrex supercharger design
- Manufactured and tested in-house at KraftWerks’ Norco, California facility to ensure quality and performance
Construction & Design:
The 30MM Boost Upgrade pulley is crafted with precision machining to exact tolerances, ensuring optimal fitment and performance within the KraftWerks supercharger system. Its lightweight design reduces rotational mass, allowing the Rotrex supercharger to spin faster and more efficiently. This upgrade complements the proprietary traction-drive technology, which is known for its compact size, quiet operation, and cooler running temperatures compared to traditional forced induction methods.
By increasing the pulley diameter, the supercharger’s boost output is raised without compromising reliability or drivability, making it an excellent choice for enthusiasts looking to extract more power from their naturally aspirated boxer engines.
Installation & Fitment:
This pulley upgrade is a direct fit replacement for the factory pulley included in the KraftWerks base supercharger kit. It is compatible with the following vehicles:
- Scion FR-S Base (2013–2016)
- Subaru BRZ Limited (2013–2020)
- Subaru BRZ Premium (2013–2019)
- Subaru BRZ Series.Blue (2015)
- Subaru BRZ Series.HyperBlue (2016)
- Subaru BRZ TS (2018, 2020)
- Toyota 86 Base (2017–2020)
- Toyota 86 GT (2018–2020)
- Toyota 86 Special Edition (2017)
Installation requires removal of the existing supercharger pulley and replacement with the 30MM Boost Upgrade pulley. No cutting, drilling, or special tuning is required beyond the standard KraftWerks supercharger kit setup, though proper belt tension and alignment should be verified during installation.
