Looking for power

[Ron1]

Jeff hit the nail right on the head. The Eaton off the 03-04 would cost an arm and a leg to install. Pump, injectors, throttle body, throttle cable, cruise control cable extension, intake manifold, intercooler, P/S relocation bracket, intercooler pump, intercooler reservoir, alternator relocation bracket, idler brace, idler pulleys, hoses, hardware, clamps. The second problem is that the 03-04 Cobra, just like on the Lightnings, run a secondary crank pulley to drive the blower which is 7 3/4 inches in diameter. The stock GT pulley is 6 1/4 inches. Figure every inch in diameter on the lower pulley is worth about 4 pounds of boost. So even if you run a 2.8 upper, it will never really make any boost. JMS in Miss. and FS in Washington just tested a new setup from a company called Tork Tech Inc. that uses a new Magnuson M112. Made 385 rwhp at 7-8 pounds of boost.
