Uses stock crank pulley. No oversize expensive crank pulley required for higher boost. And it fits under the stock hood. Only a Kenne Bell BOOST-A-PUMP™ is needed for 700HP. No larger pumps, lines, rails, injectors necessary. After 700HP, upgrade the fuel system. We recommend using 2003 Cobra style rods and pistons. Use 60lb injectors and Big Oval Throttle Body

The most popular kit for the “stock” engine Cobra. All the boost (11.5-24 psi) the engine will handle. Huge gains over stock Eaton. Great kit for 11.5-18 street and 18-24 weekend drags with racing fuel. Complete kit. Gaskets included.
