The VMP 2.3L TVS Supercharger upgrade is a direct replacement for the factory Eaton M112 Supercharger on the 2003-2004 "Terminator" Mustang Cobra. It was designed from OEM CAD data to fit perfectly and clear the stock hood. 

The VMP TVS is the first aftermarket supercharger housing made specifically to fit the Cobra. It is a one piece housing with a side inlet like the factory supercharger. The one piece design makes for a very rigid housing, allows for a larger rear inlet, decreases the chance of vacuum leaks, and makes installation easier. 

The VMP TVS for 03-04 Cobra is now available with the new elbow design to support use of a GT500 mechanical linkage throttle body. FRPP M-9926-SCJM Single blade or M-9926-CJM Dual 65mm throttle bodies are compatible. This TB has a larger bolt-pattern and allows for more airflow into the TVS, making the 2.3L blower capable of over 700RWHP. NOTE: GT500 and VMP throttle bodies use a 5" opening, it's recommended to use a 4.5" to 5" silicone reducer for use with standard 03-04 Cobra CAIs.

With the VMP TVS you get the reliability of an Eaton blower and the performance of the TVS rotorpack design. The Twin-Vortices-Series compressor has proven itself to be highly efficient over a wide operating range of 10-22+psi. It is a high twist symetrical 4-lobe rotor design with excellent adiabatic effiency. TVS technology is used on the 2013 GT500, ZR1 Corvette, and ZL1 Camaro.

  • Side inlet for easy access to fuel rails 
  • Side inlet allows use of different throttle body styles 
  • Vacuum line connections and T-MAP in factory locations 
  • Large 45MM bypass-valve for cooler operation, improved driveably, and greater fuel efficiency 
  • Removes EGR system and boost dump valve for a cleaner look and better performance 
Package Includes: 

  • VMP TVS Blower with stainless steel 6-bolt hub 
  • One pulley of your choice 
  • Inlet elbow for your throttle body style 
  • Six M6x14MM bolts for pulley

  • The TB gasket may be re-used in most cases, aftermarket TBs usually include a new gasket 
  • If you still have EGR you will need to remove it and cap the header or manifold 
  • EGR is easily turned off in the calibration to prevent a check engine light. Many emissions tests allow for one or two systems failed.

When adding a larger blower, you will need to supply your engine with more fuel as the stock fuel system cannot support the power these blowers produce out of the box. Lethal Performance and DivisionX have done it again! This time we're going to change the way the fuel delivery market works by offering our customers the ability to go return style but without the entire cost of a full on return style fuel system. Even better, with this new budget return style system you'll still utilize the stock feed line, stock fuel rails and stock fuel tank. This system comes complete with everything you need. Just install it and get your car tuned for the return style setup and you're good to go. 

How's it work? 

It starts with a DivisionX billet fuel hat that houses (2) return style Walbro GSS342 pumps. The fuel hat installs in your stock fuel tank. Then we use the DivisionX hat to stock line adapter to connect the hat to your stock feed line. The next piece is a industry changing adapter that installs a DivisionX two port fuel pressure regulator onto your stock rail. Included is a 100psi liquid filled mechanical fuel pressure gauge, vacuum hose and t-fitting which allows proper installation of the regulator. From the regulator we provide a -6an return line which returns the fuel back to the tank through the DivisionX fuel hat. The last piece of the kit is our famous Lethal Performance dual return style harness which features (2) 20amp relays, (2) 10ga power and ground wires and dual 10ga power wires from the battery. In addition our harness and hat use OEM 6 pin connectors to make it a plug and play setup which requires no soldering. 

If you're unfamiliar with a return style kit here's how it works. 

The fuel pumps are wired to run full time. Fuel pressure is set by the mechnical fuel pressure regulator. The excess fuel bleeds off the regulator through the return line and back to the tank. In this system we use a boost reference regulator. That means that for every 1psi of boost the regulator see's it's going to mechanically raise fuel pressure by 1psi. So if you start with a base pressure of 40psi and make 20psi of boost you'll end up seeing 60psi of fuel pressure when in full boost. What's great about a return style fuel system is that it's easy to tune, doesn't use any returnless style electronics and works great for both street and track applications. We run return style systems on our 2011 5.0L GT, 2010 GT500 and 03 Cobra. There's no reason to look back once we went return as we now know how well the return style system works. 

Kit Includes: 

  • DivisionX Dual Pump Return Style Fuel Hat 
  • DivisionX Two Port Fuel Pressure Regulator 
  • (2) Walbro GSS342 Fuel Pumps 
  • DivisionX Hat to Stock Line Adapter 
  • DivisionX Regulator to Rail Adapter 
  • 0-100 PSI Liquid Filled Mechanical Fuel Pressure Gauge 
  • Lethal Performance Dual Pump Return Style Wiring Harness 
  • All fittings and hardware needed for installation 
  • E85 Coating STANDARD!

** This system does not use an FPDM. It also does not require the use of a FRPS (Fuel Rail Pressure Sensor). Some tuners still prefer to keep a FRPS installed on a return style fuel system to help in tuning of the vehicle.If you would like to use the FRPS with this kit you can use the DX-8118 adapter
