Since 2003, no other performance product has created more excitement for Cobra owners than the shrill billet whine of a Kenne Bell Twin Screw. Up to 378HP more HP over stock (744-366=378HP). Our most popular Street Kits. Huge HP potential. Plenty of room to grow. Best $/HP value. Far more HP than porting Eaton, headers, heads, cams, x pipe. Big bad billet BIG BORE™ H Series uses less engine HP to drive than OEM Eaton (up to 85HP) and 56HP less than other Twin Screws (2.6, 2.8, 3.0L). That means more HP to the rear wheels.
Also 30° cooler air charge temp than other Twin Screws. Boost won’t drop off or is limited to 13 psi. Range of 9-18 psi on the street and up to 24 psi for weekend competition with only pulley change. 744HP at 23 psi on a 100% stock engine (no headers, heads or cams) thru the cats with just a cat back and Kenne Bell Cool Air Kit.
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
Kit features the latest breakthrough Kenne Bell technology e.g. 2.8LC, 3.0LC Series (up to 56 more HP and 30° cooler air charge temp than other Twin Screws) coupled to the new over the top MAMMOTH™ Inlet System that leaves the competition gasping for air. The MAMMOTH™ 2.8 may cost more, but comes standard with COMPLETE CAK, 4-1/2” Filter, 4-1/2” Ram Tube, 4-1/2” Integral Meter, Dual 75mm Throttle Body (industry’s largest) and the MAMMOTH™ Inlet Manifold with billet engraved identity plaques. Not a cobbled together – hope it works grab bag inlet system. The secret to the incredible HP potential (1100 HP rated) is the COMBINATION of supercharger and inlet system. Higher HP levels demand a larger inlet tract. That would be a no brainer. Any one inlet component that is restrictive (manifold, throttle body, ducts, meter or filter) will limit and kill HP and the higher air flow demanded by the supercharger.
Fits under the stock hood, but the big MAMMOTH™ Manifold and larger 2.8 decrease hood clearance limiting boost to minimum 18.5 psi (max for street) with the stock 7.5” crank pulley and 3-1/2” supercharger pulley. Note: Use optional 6.55” crank pulley x 3-1/2” supercharger pulley for 15 psi (see Tech & Tuning Tips ‘03 Cobra MAMMOTH™ Kit). Some cars get by with a 3-3/4”x7.5” (17 psi). Check for clearance with clay. Kit includes battery relocation kit to left side. Right side fenderwell lacks the air flow capacity and space for high HP levels. Kenne Bell BOOST-A-PUMP™ is needed at 450HP.
