2002_Ford Mustang GT Upgrades Kenne Bell Twin Screw Supercharger Kit
Kenne Bell 9 psi vs. Kenne Bell 11 psi
One of the things owners love about the new '03 Cobras is the ability to dial in extra horsepower with additional boost. The new Kenne Bell kit provides GT owners with the very same ability (only easier) as the fuel system mods (boost-a-pump, injectors and custom chip) combined with the ease of pulley changes make adding power for those trips to the track a five-minute job. Need proof? Here is the result of a pulley change from the 9-psi pulley (2 7/8 inch) to a smaller 2 5/8 inch. The pulley change took only a couple of minutes, as we were able to utilize the same drive belt. Adding the 2 5/8-inch pulley upped the boost pressure by 2 psi and pushed the power peak from 400 to 428 hp, with impressive power gains registered throughout the rev range. It is this dramatic gain in average power that really helps drop e.t.'s (assuming available traction) and increase trap speeds. The increase in boost pressure from the pulley change required no changes to the programming in the chip and the peak charge temperature increased only by an insignificant 1-2 degrees (something that speaks volumes about the effectiveness of the air-to-water intercooler system employed in this kit).
