Introducing the Magnuson Heartbeat 2650 LS3 Supercharger
The original Heartbeat 2300 paired serious LS performance with clean, low-profile packaging. The Heartbeat 2650 carries that approach forward, combining the airflow and efficiency of the TVS2650 rotor pack with dual charge-air coolers and the capacity to support more than 1,200 horsepower. Designed to fit beneath a factory C6 Corvette hood, it delivers maximum performance while preserving the compact packaging that made the original Heartbeat legendary.
Big Potential. Low Profile.
Built around a 2650 supercharger with dual charge-air coolers, the Heartbeat 2650 is capable of supporting more than 1,200 horsepower while fitting beneath a factory C6 Corvette hood.
Reaching that power level requires a properly built engine, adequate fuel system, and professional calibration.
Initial Availability
The first release is expected in late October 2026 for LS3 hot-rod applications using the Corvette accessory drive. A complete C6 Corvette kit is targeted for late 2026.
