The HP-F LT1 Harrop TVS2650 Supercharger Package has been engineered for enthusiasts seeking exceptional performance, instant throttle response and supercar-level acceleration from their LT1-powered vehicle. Built around the renowned Harrop TVS2650 Supercharger System and supported by custom calibration and proven reliability upgrades, this package delivers a dramatic increase in horsepower and torque while maintaining excellent drivability.

Every upgrade begins with a comprehensive pre-upgrade dyno assessment, establishing baseline power and torque figures before any modifications are carried out. This provides a benchmark against which the final performance gains can be accurately measured.

At the heart of the package is the Harrop TVS2650 Supercharger System, featuring Eaton's latest TVS rotor technology. Designed specifically for the LT1 platform, the supercharger delivers instant boost response, immense mid-range torque and substantial horsepower gains throughout the entire rev range. The result is stronger acceleration, sharper throttle response and a driving experience that transforms the vehicle's performance capabilities.

To further enhance boost consistency and reliability, the package includes a Griptec supercharger pulley upgrade, helping maximise belt grip and maintain stable boost levels under high-performance driving conditions. A Harrop balancer pinning kit is also installed to provide additional security and reliability for the harmonic balancer under increased engine load.

Supporting modifications include upgraded spark plugs and all necessary fluids, gaskets and consumables to ensure the vehicle is completed to the highest standard.

To unlock the full potential of the supercharger system, HP-F performs a complete custom ECU calibration using HP Tuners software. Extensive dyno testing is utilised to optimise fuel delivery, ignition timing, airflow modelling and boost control, ensuring safe, reliable and repeatable performance gains while maintaining excellent drivability.

The package also includes a custom TCU (Transmission Control Unit) calibration, designed to improve shift quality, increase shift speed and optimise transmission behaviour to fully utilise the significant increase in power and torque.

Once tuning is complete, every vehicle undergoes comprehensive dyno and road testing to verify performance, drivability and reliability. A final dyno run is then completed to compare against the original baseline figures, clearly demonstrating the gains achieved through the upgrade.

At the completion of the package, you'll receive a detailed dyno report showcasing the final power and torque figures. The result is an LT1-powered vehicle that delivers explosive acceleration, immense torque and a truly exhilarating driving experience, while retaining the reliability and refinement expected from a professionally engineered HP-F performance package.

Experience the next level of LT1 performance with HP-F's Harrop TVS2650 Supercharger Package, delivering instant boost, incredible power and dyno-proven results.
