    All new at Lethal Performance is another amazing product from our good friends over at divisionX. For some time now we've seen the need for a better fuel rail solution. Up until now the rails available to the market had not fit all applications as well as there were a few applications that required modification for them to fit.

    PROBLEM SOLVED!

    As we worked with divisionX to make a better designed fuel rail the objective was to make a higher quality rail than anyone else which will fit all applications. An example of this is the 2.3L Whipple for the 03-04 Cobras. The plenum on the 2.3L Whipple was designed to flow as much air as possible. In doing so it's quite large and causes interference with aftermarket rails. To this day you would either have to grind the underside of the plenum and rail or run a supercharger spacer to space the Whipple off of the lower manifold creating more room for the rail to clear the plenum. For most no one wants to start grinding their $3000+ supercharger and it's kept many from upgrading their fuel systems.

    We're proud to say that the divisionX rails do not have to be spaced, ground down or modified to fit any of the aftermarket twin screw blowers. Fitment has been confirmed on: 2.3L and 3.4L Whipple Supercharger in addition to the 2.2, 2.4. 2.6 and 2.8L Kenne Bell blowers.

    There's more to the divisionX Rails then fitment as they also provide some features that no other rail on the market does. Up until now if you wanted to run an electric fuel pressure gauge you would need a fuel block that mounted in between the aftermarket rail and fuel rail pressure sensor. Same goes for tapping into the rail for a nitrous setup. The additional block is no longer needed with the divisionX Rails as they have 2 ports machined into them already. This allows for you to run the fuel pressure sending unit or nitrous connection by simply screwing the sending unit or NPT fitting into the already machined ports.

    Another huge feature of the divisionX rail is the actual design. Due to the way some other rails on the market have been designed leaking fuel at the injector can occur. This is because the rails do not sit 100% on top of the injectors. They are mounted to the manifold in a way which tilts the rail on an angle and keeps them from properly sitting on the injector. The angled design compromises a secure fit.

    The divisionX rails however have a complete uncompromised fit which sits straight on the injector providing a leak proof seal. Not only is this the way the rails should fit on the injectors but when looking at the divisionX rails mounted on the car they are straight and look how they should.

    divisionX Fuel Rail Features:

    These are the most well conceived fuel rails available for this specific application:

    -OEM positioning, orientation, and size of o-ring seats for injectors.
    -Robust bolt on mounts for safe and reliable injector seating. Stainless steel mounting hardware included.
    -Fuel Rail Pressure Sensor positioned to not interfere with large case twinscrew superchargers. (i.e. Whipple 3.4L)
    -FRPS bank includes a 1/8" NPT fitting for remote fuel pressure sending units for in car fuel pressure gauges. Optional block-off available for return style systems.
    -Auxilliary connection bank has provisions for locking down a Kenne Bell restrictor orifice for FRPS replacement without fear of losing restrictor orifice.
    -Unique low profile design clears inlet of twinscrew superchargers. Overall rail height is the same as the OEM rails WHILE providing a 56% larger bore than the stock fuel rails.
    -SAE o-ring boss ports (-8 size) on front and back of both rails.
    -Front of rails is truncated to maximize clearance in the front of the rails. Aft of rails are positioned to maximize flexibility of supply/crossover lines.
    These fuel rails are machined from 6061-T6511 from a solid block of aluminum. There are no welds or caulk to fail.

    NOTE:
    -The divisionX Fuel Rails are sold as the rails only with no fittings. Use the dropdown menu to add the -8an fitting kit which also includes a stock line to aftermarket rail adapter.

    -3.4L Whipple owners will need to purchase the divisionX remote FRPS mount kit. This will properly relocate the FRPS from interfering with the massive 3.4L Whipple compressor. (Also listed as a dropdown menu option)

  29. CP-e Mustang Triple Pump TopHat with Pumps (13-14 GT500 / 11-20 GT / 12-13 Boss 302 / 15-20 GT350 / 2020 Shelby GT500)

    From: $629.94

    To: $740.14

    The TopHat™ is the ultimate solution for all fueling needs, designed to take up to three 400lph / 465Lph / 485lph / 535lph fuel pumps. The design was also intended to be plug and play, easy to install and reliable with many features to make the transition easier and have you on your way to meeting your power goals.

    The TopHat™, engineered and manufactured by Custom Performance Engineering, Inc., is the ultimate in upgrades for the fueling system. Accommodating those wanting to run two pumps for a bump in power, to those targeting 1200hp with ethanol – this setup is the all in one solution.

    The design of the fuel system supports up to three 400lp, 465lph, 485lph, 535lph fuel pumps, delivering more fuel than the more standard 255lph pumps. The pumps are secured with O-rings for optimal height and to isolate vibrations from the aluminum body of the system.

    To cut the cost of upgrading, simplify the amount of parts and eliminate additional plumbing to reduce leaks we have integrated the merge for the three fuel pumps in the hat itself. Ease of installation is always a big concern for our customers and cp-e™is striving to deliver in this department.

    Any fuel coming back through the return line is fed down through a ½” stainless steel tube to the bottom of the tank. This helps eliminate aeration of the fuel, providing a more consistent pickup. To further reduce aeration a side port has been incorporated, channeling fuel away from the pump pickup. The supplied O-ring plug blocks off one direction or the other.

    Reverse engineering using a CMM arm, modeling OE components and with precision CNC manufacturing we are able to make the TopHat™ as plug and play as possible. We utilize the factory siphon system to extract fuel from the other side of the fuel tank. Necessary features have been CNC milled to mimic OEM design to accommodate the factory level sender, placing it in the exactly the same position as OEM.

    The wiring harness is isolated and sealed from the fuel tank with a proprietary Delrin wire seal. Delrin has one of the highest resistances to fuels of any plastic, so it was chosen to provide a lifetime of trouble free operation.

    $439.99

    All new for the Ford 2020+ 5.2L Shelby GT500 are the DivisionX billet high flow fuel rails. When making more power on your GT500 or running other fuel types such as E85 we have seen pressure drops at the fuel rails when using the stock rails. This is due to the poor crossover design of the factory fuel rails. We designed our new billet fuel rails to not only fix this issue but to give you a better looking engine bay as well.

    This is the complete fuel rail kit for your 2020 Shelby GT500 and comes with the fuel rails as well as all necessary hoses, fittings and adapters to install on your car using the factory fuel line feed.
    All of the hoses in this kit are pre-assembled Fragola PTFE hose. The Fragola PTFE hose prevents any fuel smell unlike other non PTFE hoses. The Fragola PFTE hose consists of an inner PTFE lining which is covered in a stainless braid and then has a black plastic protective sheath on it. This not only gives the hose a much stealthier look but also prevents any type of scratching to your vehicle from a stainless braided hose.

    The DivisionX 2020 Shelby GT500 fuel rails feature -8an ports on each end the rail and have the provision for the stock fuel line. They also come with an additional 1/8" NPT port for either a fuel pressure gauge, sending unit or wet nitrous system connection. High strength mounting tabs and hardware also included.

  • Lethal Performance 2013-2014 Shelby GT500 V2 Return Style Fuel System (Traditional Style - Regulator After the Fuel Rails)
    $2,349.00

    With the release of the DivisionX S197-C fuel hat, we're excited announce several different return style fuel systems for the 2013-2014 GT500 owner in need of more fuel. 

    These fuel systems are designed to help safely support higher hp levels and come with everything needed for a complete installation. So whether you're looking to support 700rwhp or 2000rwhp, we have a kit specifically designed just for you. 

    The all new V2 system is run in a traditional style where the regulator is placed after the fuel rails. Fuel is fed from the DivisionX fuel hat through a 10an feed line to our high flow fuel filter. From there it splits at a Y-block into -8an feed lines. Each line then feeds the rear of each fuel rail indivisually and returns out of the front of the fuel rails to the Aeromotive Pro Series regulator where it's then returned to the tank using a -8an return line.

    NOTE: This system comes standard with Fragola PTFE fuel hose. PTFE fuel hose is more durable than the standard hose and prevents fuel smell typically found when using non PTFE hose.We have used the standard Fragola non-Teflon based fuel hose on several of our shop cars with both gasoline and E85 with excellent results and no fuel smell. If you would like the non PTFE hose please choose that option from the dropdown menu. If you decide to purchase this kit with the standard hose Lethal Performance will not be liable for claims of fuel smell after installation.

    One of the major improvements these new systems offer are the single feed line. In the past, our systems used a different fuel hat which required the use of a 3-into-1 y-block. That also created the need for more lines and fittings making the system cost more and more difficult to install. The new systems use the DivisionX hat which has a single outlet and single return eliminating the use of an external y-block.

    The DivisionX fuel hat is a direct replacement for your stock fuel hat. Simply remove the stock setup and the DivisionX hat drops right in. The DivisionX hat uses the same OEM venturi setup and level sender as the stock pump system did so your fuel level will always read accurately. 

    Easy to Upgrade- If at any point you grow out of the system you're in and need to step up to the next system to support more hp all you need is the pumps as all of the systems are the same except for the pumps.

  • Lethal Performance 2010-2012 Shelby GT500 V2 Return Style Fuel System (Traditional Style - Regulator After the Fuel Rails)
    $2,299.00

    With the release of the DivisionX S197 fuel hat, we're excited announce several different return style fuel systems for the 2010-2012 GT500 owner in need of more fuel. 

    These fuel systems are designed to help safely support higher hp levels and come with everything needed for a complete installation. So whether you're looking to support 700rwhp or 2000rwhp, we have a kit specifically designed just for you. 

    The all new V2 system is run in a traditional style where the regulator is placed after the fuel rails. Fuel is fed from the DivisionX fuel hat through a 10an feed line to our high flow fuel filter. From there it splits at a Y-block into -8an feed lines. Each line then feeds the rear of each fuel rail indivisually and returns out of the front of the fuel rails to the Aeromotive Pro Series regulator where it's then returned to the tank using a -8an return line.

    NOTE: This system comes standard with Fragola PTFE fuel hose. PTFE fuel hose is more durable than the standard hose and prevents fuel smell typically found when using non PTFE hose.We have used the standard Fragola non-Teflon based fuel hose on several of our shop cars with both gasoline and E85 with excellent results and no fuel smell. If you would like the non PTFE hose please choose that option from the dropdown menu. If you decide to purchase this kit with the standard hose Lethal Performance will not be liable for claims of fuel smell after installation.

    One of the major improvements these new systems offer are the single feed line. In the past, our systems used a different fuel hat which required the use of a 3-into-1 y-block. That also created the need for more lines and fittings making the system cost more and more difficult to install. The new systems use the DivisionX hat which has a single outlet and single return eliminating the use of an external y-block.

    The DivisionX fuel hat is a direct replacement for your stock fuel hat. Simply remove the stock setup and the DivisionX hat drops right in. The DivisionX hat uses the same OEM venturi setup and level sender as the stock pump system did so your fuel level will always read accurately.

    Easy to Upgrade- If at any point you grow out of the system you're in and need to step up to the next system to support more hp all you need is the pumps as all of the systems are the same except for the pumps.

    All new at Lethal Performance is another amazing product from our good friends over at divisionX. For some time now we've seen the need for a better fuel rail solution. Up until now the rails available to the market had not fit all applications as well as there were a few applications that required modification for them to fit.

    PROBLEM SOLVED!

    As we worked with divisionX to make a better designed fuel rail the objective was to make a higher quality rail than anyone else which will fit all applications. An example of this is the 2.3L Whipple for the 03-04 Cobras. The plenum on the 2.3L Whipple was designed to flow as much air as possible. In doing so it's quite large and causes interference with aftermarket rails. To this day you would either have to grind the underside of the plenum and rail or run a supercharger spacer to space the Whipple off of the lower manifold creating more room for the rail to clear the plenum. For most no one wants to start grinding their $3000+ supercharger and it's kept many from upgrading their fuel systems.

    We're proud to say that the divisionX rails do not have to be spaced, ground down or modified to fit any of the aftermarket twin screw blowers. Fitment has been confirmed on: 2.3L, 3.0L, 3.4L, 4.0L Whipple Superchargers / 2.2L, 2.4L, 2.6L and 2.8L Kenne Bell blowers. VMP 2.3L, 2.65L Gen3 / Gen3R Superchargers.

    There's more to the divisionX Rails then fitment as they also provide some features that no other rail on the market does. Up until now if you wanted to run an electric fuel pressure gauge you would need a fuel block that mounted in between the aftermarket rail and fuel rail pressure sensor. Same goes for tapping into the rail for a nitrous setup. The additional block is no longer needed with the divisionX Rails as they have 2 ports machined into them already. This allows for you to run the fuel pressure sending unit or nitrous connection by simply screwing the sending unit or NPT fitting into the already machined ports.

    Another huge feature of the divisionX rail is the actual design. Due to the way some other rails on the market have been designed leaking fuel at the injector can occur. This is because the rails do not sit 100% on top of the injectors. They are mounted to the manifold in a way which tilts the rail on an angle and keeps them from properly sitting on the injector. The angled design compromises a secure fit.

    The divisionX rails however have a complete uncompromised fit which sits straight on the injector providing a leak proof seal. Not only is this the way the rails should fit on the injectors but when looking at the divisionX rails mounted on the car they are straight and look how they should.

    DivisionX Fuel Rail Features:

    These are the most well conceived fuel rails available for this specific application:

    -OEM positioning, orientation, and size of o-ring seats for injectors.
    -Robust bolt on mounts for safe and reliable injector seating. Stainless steel mounting hardware included.
    -Fuel Rail Pressure Sensor positioned to not interfere with large case twinscrew superchargers. (i.e. Whipple 3.4L)
    -FRPS bank includes a 1/8" NPT fitting for remote fuel pressure sending units for in car fuel pressure gauges. Optional block-off available for return style systems.
    -Auxilliary connection bank has provisions for locking down a Kenne Bell restrictor orifice for FRPS replacement without fear of losing restrictor orifice.
    -Unique low profile design clears inlet of twinscrew superchargers. Overall rail height is the same as the OEM rails WHILE providing a 56% larger bore than the stock fuel rails.
    -SAE o-ring boss ports (-8 size) on front and back of both rails.
    -Front of rails is truncated to maximize clearance in the front of the rails. Aft of rails are positioned to maximize flexibility of supply/crossover lines.
    These fuel rails are machined from 6061-T6511 from a solid block of aluminum. There are no welds or caulk to fail.

    NOTE:
    -The divisionX Fuel Rails are sold as the rails only with no fittings. Use the dropdown menu to add the -8an fitting kit which also includes a stock line to aftermarket rail adapter.

    While Whipple broke many rules and records with its record setting S550 supercharger system, holding the title of the most powerful, most advanced supercharger system available, we weren't satisified and decided to build an all new supercharger from the ground up.The new, direct and port injected supercharger system features the brand new Generation 5 3.0L front feed twin-screw supercharger. Not to be confused with the Gen 3 or 4, this all new Gen 5 supercharger features industry leading efficiency from idle to redline. All new bearings, gears, rotors and housing allow the new supercharger to spin faster, longer and safer while producing more power than any other positive displacement supercharger ever built..

    The 2018 also features an even larger intercooler than the already massive Whipple Cooler that cooled the Ford Cobra Jets and all the record setting S550 Mustangs. Couple this with the industry's leading heat exchanger, water reservoir and intercooler pump, you get more power with lower boost levels and quicker recovery times after aggressive operation..

    With years of OEM and racing experience, Whipple engineers have developed a unique PCM calibration that reconfigures all the necessary engine functions including fuel, spark, knock detection, torque management, transmission control and electronic throttle control. The vehicles PCM constantly monitors the engines torque output while monitoring many different parameters to keep the engine in it’s ideal parameters. If a parameter falls below specification, the PCM will lower boost and torque output until the problem can be cured. No other calibration in the field has such technology, giving the Whipple SC system unheralded performance and reliability. Each Whipple kit comes with unique software and a OBDII flash tool giving the customer the ability to flash/update whenever nLearn More
