Description
2.8LC, 3.2LC LIQUID COOLED
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, 3.2L. That means more HP to the rear wheels. +70HP over Eaton at a mere 13 psi +38 from parasitic loss only).
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 23psi 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.
2.6
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 11.518 street and 18-24 weekend drags with racing fuel. Complete kit. Gaskets included.
2.8
Same features as 2.6 but better choice for modified engines as heads, headers, exhaust and stroker kits reduce boost, .75″ longer case for higher boost/HP capacity. 2.5 psi more boost with same pulley size vs. 2.6L. Minimum boost is 14.5 with stock crank pulley. Max 26 psi.
2.8, 3.2LC MAMMOTH
The “King of Twin Screw Kits.” For those who want maximum HP potential from a Twin Screw Kit.
2.8LC MAMMOTH
Same as 2.8 Mammoth only Liquid Cooled.
