What Does This Do?
Magnuson's TVS2650 is their flagship roots-style supercharger for the 6.4L HEMI. Unlike centrifugal superchargers that build boost at high RPM, a roots blower makes instant torque — you feel the power the moment you touch the throttle. This is the COMPLETE kit, meaning it includes everything: the supercharger, intake manifold, fuel injectors, fuel rails, all hardware, and a pre-loaded tune. You do NOT need to buy additional fuel system parts. The TVS2650 compressor is extremely efficient and runs cooler than older roots designs, meaning more reliable power. Expect 150-200+ HP depending on supporting mods.
Required Supporting Parts
This supercharger kit requires additional parts for safe installation. Installing without these can cause serious engine damage.
A custom ECU tune is REQUIRED for any supercharger installation. The factory tune cannot manage boost, and running a supercharger on a stock tune will cause dangerous lean conditions and likely engine damage.
Supercharger 'Tuner Kit' purchases REQUIRE upgraded fuel injectors. Complete kits include injectors. Without enough fuel flow, the engine will run dangerously lean under boost, causing detonation and catastrophic engine damage. Verify your kit type before proceeding.
A fuel pump upgrade is strongly recommended for supercharged builds. The stock pump may not supply enough fuel volume at high RPM under boost. This is critical for engine safety — fuel starvation under boost destroys engines.
Cooling upgrades (radiator, thermostat) are strongly recommended with a supercharger. Forced induction dramatically increases heat — the stock cooling system may not keep up, especially in hot weather or traffic.
Colder spark plugs are recommended with a supercharger. Higher combustion temperatures under boost can cause pre-ignition with stock-heat-range plugs.
Fitment Notes
6.4L HEMI only. Not for 5.7L (see TVS2300 kit).
Tune Required
This part requires an ECU tune to function correctly. Without a tune, the engine computer won't adjust for the new part, potentially causing poor performance, check engine lights, or engine damage.
