Whipple Superchargers 2016-2020 Ford Shelby GT350 / GT350R 5.2L Gen 6 3.0L Supercharger Kit
Complete Gen 6 W185ax 3.0L twin-screw system for the 2016-2020 GT350/GT350R – up to 875 HP on 93 octane, 50-state legal (CARB D-231-87), HP Tuners MPVI4 + Whipple cal included. PN WK-2621-30.
Whipple Gen 6 3.0L — Shelby GT350 / R
The W185ax twin-screw that turns the flat-plane 5.2L Voodoo into an 875-horsepower street weapon — the most powerful 50-state-legal system you can bolt to a GT350. Complete kit, PN WK-2621-30.
An entirely different league.
The GT350 and GT350R are already special cars — a properly engineered Whipple twin-screw takes the 5.2L platform somewhere else entirely. Instant torque, violent mid-range pull, and a relentless charge to the 8,250 rpm redline, while keeping the refinement a premium Shelby build deserves.
Since 1987, Whipple has led twin-screw supercharging. The Gen 6 W185ax 3.0L moves more air with less effort than 1.9L/2.3L roots systems — 30% more displacement means lower discharge temps and less parasitic loss. On 93 octane, the complete system supports up to 875 HP and 660 lb-ft. No other upgrades required.
Daily refinement. 875 HP violence. Pick both.
OEM-grade drivability with the oversized intercooled air-bypass cutting burst knock, parasitic loss and even improving cruise fuel economy. It idles, it commutes, it behaves — on factory-feeling manners.
More boost at the hit than any competing twin-screw, a dead-flat torque curve, and the patented dual-core dual-pass intercooler keeping charge temps down when heat becomes the enemy. The Voodoo finally gets the midrange it deserved.
