FIRST 5.0 SUPERCHARGED COBRA JET IN 7'S
7.91 / 175.8
Johnny Lightening • 1500 HP • NMRA Coyote Modified Class Winner
Kenne Bell 3.6L Rear Inlet • BIGUN DUAL 106MM • BIGUN INTERCOOLER
• Cool air kit included.
* 2.8 vs. 2.9 tests run at same cfm clearly prove 2.8 superior. PC (power consumption or parasitic loss) and DT (discharge temps) were lower with 2.8 and we can prove it.
Larger cams, headers, exhaust, cat back exhaust or removing cats will improve engine air flow / breathing and lower boost. All above data is "stock" engine, headers, exhaust etc. so out of the gate customers know what gains to expect from our supercharger kits. 1501HP is a built motor with BIGUN manifold and Dual 106MM throttle body.
Developing maximum HP not only requires a more efficient supercharger and intercooler but also a high flow discharge manifold, the last component in the air flow path to the cylinder heads.
To minimize restriction and resultant boost/HP loss between the intercooler and engine head parts, we completely eliminated the 8 long 180° restrictive intake manifold runners.
In their place are "open no runner plenums" that dump unrestricted and balanced air flow to all ports.
Our complete 5.0 manifold and intercooler assembly out flowed the competitions "180° long bend" design by 15% Simple: No runners - no restrictions.
Check out the size and cfm of Kenne Bell Mammoth manifolds and throttle bodies as compared to front inlet systems.
The Kenne Bell Mammoth Rear Inlet Systems are the largest highest HP potential systems available. They flow more air at ANY HP and boost level up to 26psi and 1400 HP. Only an easy bolt on throttle body upgrade is recommended at higher HP. No new manifolds, machining, tubes, meter or filter required
The huge Kenne Bell Rear inlet systems flow 1850 cfm vs. the stock Mustang at 772 cfm. Our favorite sign at Kenne Bell reads: "Air flow isn't the only thing... it's everything." Kenne Bell Kits have less restriction, flow more air and cooler air. so they make more HP than front inlets.
Who doesn't know that choking off the inlet of the supercharger kills HP? Nothing is more crucial to supercharger efficiency than the inlet system (filter, pipe, meter and throttle body). Starve the supercharger and it develops less boost, heats the air charge and consumes more engine HP to drive. Not good. It is also well known that the air flow and HP potential of any inlet tract is limited by the smallest component - usually the throttle body. To guarantee our kits produce more HP, we offer only proven superior rear inlet kits - the standard industry leading 4.5” Mammoth® with 168mm/2350 cfm throttle body and optional BIGUN Dual 106mm/3800 cfm. These big inlet systems coupled to the largest and/or most efficient 2L, 3L and 4L superchargers is why Kenne Bell is so dominant in Ford supercharging.
These back to back tests were run to illustrate the big HP advantage of a larher throttle body. In this casem our industry leading 168mm (2150 cfm) vs the Shelby dual 60mm (1128 cfm at various boost/HP/cfm levels.
The higher the engine HP level the greater the HP gains.
Using the little stock 80mm in place of the SHelby dual 60mm will drop yet another 15HP. A smaller filter, meter, inlet pipe and manifold will further restrict air flow to the throttle body. Bigger is better.

• 168mm standard on all 5.0 kits
• + 39HP @ 10PSI vs 80mm. + 24HP vs dual 60mm
• No expensive retuning and dyno testing
• Matching 4.5" Mammoth Cool Air Kit
• Same 168mm used on 3.2, 3.6, 4.2, 4.7 kits
• 50 State Legal
FUEL SYSTEM - The KB BOOST A PUMP and ID1000 injectors supported 737RWHP on the automatic and 755RWHP on manual cars. That was max HP. Both will run low 10’s @ 16psi with 100% stock engines and suspension. And no headers, cams, heads, NOS etc. – just a 2.8 kit. The Boss 302 3.6L car tested for MM & FF Magazine made 845RWHP @ 21psi with a 100% stock fuel system and only a competition BOOST A PUMP and ID1000 injectors.
The 2.8 Kenne Bell Kit with it's ID1000 injectors, stock pump and NO BAP will support max 664RWHP manual trans at 11:1 AFR.
NOTE: Stock fuel lines and rails are adequate, so save your money on expensive dual pump and plumbing upgrades.
IGNITION – Fires fine with stock ignition. BOOST A SPARK will probably not be necessary until 25 + psi.
SPARK PLUGS - Use NGK 6510 gapped at .035.
INJECTORS - The stock 5.0 uses a new style “short” EV14 injector in lieu of the popular and longer EV6 style. We chose the 47lb EV6 long style injectors on our 9-11 PSI 2.8 kits to make upgrading to larger inhectors quick, easy and economical. Upgrading on a Kenne Bell Kit does not require raising fuel rails with spacer kits, injector adaptors or new fuel rails.
NOTE: Stock fuel rails will-and do- support 1400HP. At least they do on the Kenne Bell and Accufab dyno engines we’ve tested.
CLUTCH - The Centerforce Dual Disk will hold 1000HP yet has the same smooth low pedal pressure and driveability as stock.
TORQUE CONVERTER - PI (Performance Industries) dual clutch converter for high HP applications Prototype worked great.
SUSPENSION - The Eibach lowering kit is just right for height and ride quality. Just add the Nittos and hang on.
TIRES - Nitto NTO5R’s are hard to beat. We also use them on our Hemi’s, Camaros, and Shelby’ street test cars.
CAT BACK EXHAUST - Magnaflow 3” worked best lowering back pressure from 6psi to 0psi at 610RWHP. Louder than stock but not objectionable.
8/10 RIB KIT - See "Accessories." 6 rib good to 15 PSI. Use 8 rib for 15-20psi 2.8,3.2 with ATI 7.88" or Ford 6.6". 10 rib available with ATI 7.88" only.
ATI O.S. DAMPENER - Our 8 and 10 rib systems use the ATI damper. Stock is 6.6" vs. 7.24”, 7.55” and 7.88” (+ 3PSI, + 4PSI and + 6PSI). ATI is the ONLY O.S. damper we’ve used that works reliably with the 5.0 and the ONLY damper we recommend. When using O.S. dampeners, use the correct 5.0” Kenne Bell 8-10 rib kit water pump pulley for clearance. Stock is 5.5” (6” with flange) leaving “O” clearance with an 8” lower.
NOTE: Since the Kenne Bell 2.8 is over 20% larger capacity than a 2.3, it will produce 5PSI more boost with the same size pullies (ratio). See what larger 2.8L superchargers do for you – 16PSI with the stock 6.6” dampener and 3.25” SC pulley vs. 11PSI for a 2.3.
CALIBRATION & CUSTOM TUNING - All Kenne Bell kits are calibrated in house except for competition “tuner kits.” Our 50 State Legal kits do not require “custom tuning” unless modified, so save your money. We do not offer any custom tuning for headers, cams, throttle bodies, injectors etc. Check with us for a Kenne Bell Dealer Installer in your area if modifying our kits or adding non 50 State Legal product(s) that may affect driveability, emissions and/or performance.
RWHP* Man Trans HP. Deduct 30HP for auto trans numbers.
Add 40HP for E85, all else equal.
1/4 MILE TESTS
(See "SUPERCHARGER KIT HP VARIABLES")
Note: All Kenne Bell Camaro, Hemi and Ford Mammoth Kits (8-26psi) utilize the same huge 1400 HP rated “rear inlet” manifolds fed by equally large 4.5” Ram Air Pipes.
