Description: Kenne Bell, the Twin Screw gurus, have done it again. Up to 617 RWHP vs. stock 366HP with stock cats, MAF meter, throttle body and injectors from ONLY a Kenne Bell Supercharger Upgrade kit and Cobra Cool Air Kit.

Pick your boost and make a 4 minute pulley change. Run 8-15 psi on the street with 92 octane and then increase the octane for higher boost levels up to 22 psi.

The best performance product available for the 2003 Cobra. Just bolting it on at same 13 psi as Eaton increases power by 72HP. That's more than headers, exhaust, pre cats, x pipe, throttle body and mass air meter make - and there's plenty more supercharger potential power on tap.

8-20 psi kit is available in Satin Black or Polished. Includes Kenne Bell Blowzilla 2200 Supercharger, FLOWZILLA inlet manifold, Kenne Bell SWITCH CHIP® and 30 amp BOOST-A-PUMP™, Tuning Instructions and Dyno Tests for all pulley sizes. Extra pulleys - $69 (sizes 4" (9 psi), 3-3/4" (11 psi), 3-1/2" (13 psi), 3-1/4" (15 psi), 3" (17 psi), 2-3/4" (19 psi), 2-1/2" (21 psi). Kenne Bell Cobra Cool Air Kit highly recommended at any boost level.

A direct bolt on replacement. 30% lower air charge temp and 30% less parasitic (HP) loss than the stock Eaton. 70 more HP than Eaton at 13 psi (90 more HP with Kenne Bell Cobra "Cool Air Kit" ) - and the boost doesn't "drop off" from 13 to 10.5 psi as with the Eaton.

See "Snake-Bite Hit" in March '03 issue of 5.0 Mustang Magazine. Great supercharger article!
