Kenne Bell 4.2L Liquid Cooled "Mammoth" Twin Screw Supercharger
The Kenne Bell 4.2LC "Mammoth"can produce incredible power levels with stock 5.4L Shelby GT500 engines as well as highly modified engines. The revolutionary 2.0 PR compressors have the ability to run nearly 36psi of boost for unheralded performance. A 4 minute pulley change will allow you to step up or down for street or race applications.
This direct bolt-on replacement system gives you the ability to run far higher boost levels than the factory 2.1L roots-type supercharger while dramatically lowering supercharger discharge temperatures and power consumption (hp).
• 4.2LC is the Largest displacement Billet Twin Screw vs. others 2.3L Roots, and 2.9L and 3.4L Twin Screw style rotors and cast case.
• Most powerful, efficient and technically advanced kits capable of running 30lbs of Boost
• Highest HP potential (up to 2000HP).
• Liquid Cooled (Patent Pending). Cooler air charge. 60° cooler oil, gears, case, rotors, bearings and seal temps. Higher Boost and RPM Potential
• Seal Pressure Equalizer (Patent Pending) Equalizes pressure and vacuum differental across rotor seals, plus it reduces seal friction, wear and HP drag.
• New more efficient 4x6 rotor profiles. Others use 3x5 lobe rotors.
• Show quality polished Bulletproof billet. No off color paint or coatings to crack, peel, chip, discolor or seal in heat.
• New design BIG BORE rotors (4.41” vs. competitions 4.11” and 4.17”).
• 6”x4” rotor lobes vs. 5”x3” competition. Reduces male rotor speed 10% (1.5 vs 1.66 ratio).
• Hard anodized rotors for corrosion and wear protection. No Teflon to flake or rub off and clog intercooler.
• Huge boost / HP gains with same pulley ratio.
• Less rpm with same boost. Reduces friction, heat and wear.
• Cooler denser air charge temps.
• Lower parasitic loss.
• Larger pulleys - less slippage - more HP..
• Up to 33% greater belt contact patch..
• CNC machined billet inlet and outlet.
• Developed and test proven on “one of a kind” high HP supercharger dyno, engine chassis dyno and flow bench.
• Chassis dyno tested with the hood CLOSED, the way it’s driven - not OPEN as with others.
• Oil dipstick. No sight glass to discolor or stain.
• The industry’s most complete and best illustrated Installation Instructions.
• 20+ years experience in Twin Screw supercharging.
• 50 State Legal Pending
168mm Billet Throttle Body
Any one undersized inlet component can starve the supercharger and engine for air (HP). Our testing clearly indicated that the stock 60mm throttle body and manifolds became a major restriction as low as 435HP (stock HP for a Shelby). We had no choice but to develop our own 168mm Throttle Body to match the HP potential of the BIG BORE™ 4.2 Supercharger.
• Supplies whopping 78% more air to supercharger (1880 vs. 1128 stock 60mm).
• 68-88RWHP over restrictive stock 60mm
• Lowers discharge temp and parasitic loss.
• Matches opening of huge Kenne Bell Inlet Manifold.
• Manifold and Throttle Body is fed air via the matching Kenne Bell Filter/Meter/Tube Kit.
• Polished billet aluminum.
Big Oval Air Induction System
Our flow bench and dyno testing indicated the Kenne Bell 3.6Lc was capable of inhaling a lot of air - up to 1000HP. So we designed a huge oval shaped inlet system with a Big Oval 130mm Meter and Filter that measures 130mm and flows 1830 cfm. It feeds our own Dual 75mm Throttle Body and matching Inlet Manifold through an equally oversize Inlet Tube.
• Engineered as a matched pair (internally contoured to meter).
• 1830 cfm @ 28”. 1625 cfm meter only.
• Eliminates restrictive stock canister / filter / meter assembly (1830 cfm vs. 940 cfm stock)..
• Developed on 1000HP Flow Bench and Dynojet.
• Inlcudes air filter heat shield
The DiabloSport MAFia provides real world plug and play control of your vehicles "Mass Air Meter",(MAF). MAFia allows you to precisely control and regulate MAF sensor voltage eliminating the need for prefabricated "Ugly" custom MAF Housings or Sensors.
80lb EV14 High Impedance Fuel Injectors (8)
These are High Impedance/Resistance for use with the stock EEC computer. All injectors are Flow Matched within 1% and use a USCar Electrical Connector.
Shelby GT500 Dual Boost-A-Pump
A time tested and proven innovation, the Dual BOOST-A-PUMP™, powers some of the world’s most powerful production street and competition vehicles. The 725HP Shelby Super Snake (”Most Powerful Production Car Ever”),
•1000HP with OEM in tank production pumps.
•Increases fuel pump flow up to 50%
•Easily installed. Uses stock feed wire & fuel lines.
•Eliminates expensive fuel lines and pump upgrades.
•Exclusive built in regulator stabilizes voltage regardless of battery voltage (down to 11V).
•Compensates for reduced voltage/pump delivery from voltage drops by lights and accessories.
•Proven reliability and concept. Tens of thousands sold since 1995.
•Does not affect pump life. Actually increases life of returnless pumps.
•Fused circuit protection.
NGK TR6 Spark Plugs (8)
Replace your stock plugs with these NGK TR-6 Plugs, their one step colder than stock. Must be used with Shelby GT500's running more than stock boost and must be gapped at .030"!
This kit will produce at the minimum 16lbs of Boost and is highly recommended that the wimpy stock Heat Exchanger be upgraded to our High Capacity Dual Pass Heat Exchanger with Fans to insure the coolest intake charge. You can simply add it below.
