TRASK Tornado Turbo Kit Stage 2 for Gen 2 M8, Stainless with Polished Aluminum, TM-7620-PO

Tornado Turbo Kit - Stage 2 - Stainless with Polished Aluminum - Gen 2 M8

The TRASK Tornado Turbo Kit Stage 2, part number TM-7620-PO, is engineered for Harley-Davidson applications using 117-cubic-inch and larger M8 engines. With a properly built engine and suitable supporting components, this high-performance turbo system is capable of producing approximately 170–200+ horsepower on pump gasoline. The kit combines a larger TRASK turbocharger with an upgraded larger-diameter tailpipe to help support increased airflow and power potential while maintaining a purpose-built installation package.
The system features TRASK compressor and turbine housings with Garrett internals, along with a TRASK plenum incorporating an integrated blow-off valve. Included installation components are larger fuel injectors, spark plugs, a boost gauge with mounting hardware, oil feed and drain lines, a custom cam cover, ThunderMax tune files, and the required hardware and gaskets. Stage 1 Tornado Turbo customers can upgrade to Stage 2 by installing the larger turbocharger and matching larger tailpipe, making this kit a suitable path for riders seeking additional performance from an existing TRASK turbo setup.
This TRASK turbo kit requires a ThunderMax ECM, sold separately, for proper engine management and tuning. It does not fit Twin Cooled models or motorcycles equipped with fairing lowers that cannot be removed. The kit is intended for off-road use only and is recommended for experienced riders and professional installers familiar with turbocharged motorcycle systems. Verify engine configuration, motorcycle compatibility, and supporting modifications before installation.
