Whipple 03-04 Cobra W245ax Supercharger Kit (Black)

Kit includes 4.0L Blower w/ 3.50" Pulley, 123mm CAI & 160mm Monoblade Throttle Body

Introducing the largest and most powerful twin screw supercharger system available for the 03-04 Cobra. The Whipple 4.0L Super Crusher kit is the same exact supercharger used on Ford's 2010 Super Cobra Jet and the Lethal Performance 2010 GT500.  In fact Lethal Performance was the first to ever run the 4.0L on a production GT500.

The 4.0L flows 2518 CFM and has a peak rpm of 18,000. It's massive Super Crusher inlet and Super Monoblade throttle body remove all restrictions and allow this blower to make some insane power. The 4.0L also powered the Lethal Performance 2010 GT500 to be the fastest 2010 GT500 in the country with a 9.66@146.19 1/4 mile run. On our built GT500 motor with aggressive cams and extensive port work we saw peak boost of 21.5 with the 4" upper pulley and 10% lower balancer. This particular combo on a Mustang Dyno yielded us 805rwhp which equates to over 880rwhp on a Dynojet. At any point a smaller 3.5" pulley could be used to increase boost and turn this baby up.

Its highly recommended to have a built motor and supporting fuel system to be able to properly handle the power that this blower is capable of.

NOTE: Not included in this kit is the slot style MAF sensor or the pigtail needed to adapt your 99-04 style connector to the new slot style MAF. Those need to be purchased separately.
