+135HP/ +123 ft lbs. torque (108HP / 98ft lbs rear wheel @ 7 psi).
Twin Screw Design. More Efficient than the Eaton / Roots type. (Cooler air charge temp and less HP to drive)
Looks Factory. Mounts on top of engine.
Includes Kenne Bell "Open House" hi flo 20HP manifold. (Eliminates restricitive stock manifold).
Whisper Quiet. No embarassing, annoying noise.
No external oil lines or drilling holes in pan.
No other changes necessary.
Works with stock gears.
No boost lag.
60-80 degrees cooler air charge temperature and requires 10-16 less HP to drive than roots style.
No other engine or transmission changes required. Everyhting included.
Not totally dependent on rpm for boost as with centrifugals.
Fits under stock hood.
Bolts to stock lower manifold.
No intercooler required.
BOOST-A-PUMP included. Only activates under boost.
OPTIMODULE (chip) also included.
*300-650HP range. Varies with boost level.
A whopping increase of 135HP (440 vs 305) and 123 ft lbs torque (426 vs 303). This one will turn anyone's head around. "Top engine" design mounts supercharger where it belongs - on top of the 4.6 - not on the side or in between the radiator and water pump. Included with the kit is the new Kenne Bell ultra high flow "open house" manifold. No manifold will ever flow more air then this beauty. Near full rated boost at a mere 2400 RPM gives the little 280 cubic incher needed low end torque - AND MORE!
TORCO - Torco Octane Booster (Accelerator Race Fuel Concentrate) can be purchased in 5 gallon 610 oz containers for $138. That’s $.22/oz which adds $.17/gallon (3 octane) or $.34/gallon for 7 octane. Only $120-$240 for 10000 miles of big HP gains and lots of fun. 16 oz in 20 gallons is 7.0 octane. Note: Increasing the ratio above 32 oz in 20 gallons does not provide increase beyond 7 octane. When comparing octane boosters keep in mind that some advertise “octane POINTS.” It takes 10 POINTS to make one octane. Torco doesn’t contain any lead or alcohol.
LUCAS - Our other recommendation is Lucas Oil’s “Octane Booster” which nets approx. 3 octane in 20 gallons. It contains MMT (Maganese Tricarbonyl) and is the best of the MMT boosters.
DRAG STRIP PERFORMANCE
The stock ‘96-’98 Cobra will turn 14.0 @ 100 mph.
The Kenne Bell 6 psi kit will turn 12.5* @ 108 mph.
The Kenne Bell 8 psi kit will turn 12.3* @ 110 mph.
*Additional supercharger torque will require Drag Street Radials for best ET’s.
BOOST-A-PUMP™ - Set Kenne Bell BOOST-A-PUMP for boost levels shown above. The engine can't make horsepower without fuel. Higher boost increases engine horsepower and air flow through the engine. An increase in fuel delivery and fuel octane is necessary to keep pace.
IGNITION / PLUGS - Close plug gap to .035". If ignition is still inadequate (evidenced by engine miss) install the Kenne Bell BOOST-A-SPARK™. Install new 1 heat range cooler NGK TR6 spark plugs.
CHIPS - A variety of custom Kenne Bell MONO and SWITCH CHIP designs wherein we alter the fuel and spark curves for specific applications are available. Ford Cobra OBD2 computers from 1996-‘98 - we have calibrated chips for all.
PULLEYS - The big Kenne Bell 2.1L BIG BORE™ is capable of developing up to 20 psi boost.
HEADERS - Not worth the high cost. 5-10HP at best.
EXHAUST - No HP gain, but sounds good.
X PIPE - 10HP.
COOL AIR KIT - Dent in inlet tube for strut brace restricts power by 10HP. Use the ‘98 tube with Kenne Bell Cool Air Kit.
