      Crave More Power. Is your W140ax Gen II 2.3L Twin Screw Whipple Supercharger not making enough power for your needs? Then upgrade to the W175AX 2.9L Twin Screw Whipple Supercharger compressor for big power gains from your 5.0L "Coyote" Mustang.

      Upgrade Kit. The Whipple W175AX 2.9L Supercharger upgrade kit comes with everything needed to swap out the W140ax 2.3L compressor you are currently running for the larger 2.9L crusher setup. Kit includes the W175AX 2.9L compressor, EVAP relocation install kit and supercharger pulley. The 2.9L Supercharger with a 4.00' pulley will produce 10psi on a stock 5.0L engine.

      This Polished W175AX 2.9L Twin Screw Whipple Supercharger Compressor upgrade is specifically designed for the 2011 to 2012 Coyote 5.0 GT Mustangs with a W140ax 2.3L Whipple Supercharger system installed.

      Please Note: Whipple Supercharger Kits are built to order for our customers. Because of this there can be a 10 to 14 day lead time on orders.

      would this be recommend for a daily driver?

      • You can use the Whipple W175AX Supercharger Upgrade Kit (11-12 GT) on a daily driver. This will be harder to drive in traffic however. This kit will be a upgrade kit for the 2.3L Whipple. If you do not have the 2.3L Whipple this kit will not work.

      • It will depend on the supporting mods and the tune used. We recommend checking with the manufacturer or a performance shop.
