Stage 1 Kit - 4.0L Supercharger Kit Only
Introducing the largest and most powerful twin screw supercharger system available for the 07-2014 GT500. The Whipple 4.0L Super Crusher kit is the same exact supercharger system used on Ford's 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 firstname.lastname@example.org 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.
The 4.0L as far as fitment goes will fit under the stock hood with the use of the same engine lowering kit that's used to fit the 3.4L on the GT500.
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.
