Customer Reviews


Lethal Performance presents our 1,000hp capable kit for 2018+ Mustang GTs!  This kit generates a potential 1,000hp on E85 or 850hp on 93 Octane at the crank.


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 needed. Each customer also gets the new Flight Control Software, ability to adjust wheel/axle size, octane adjustment, crank/cam relearn and many other unique features.


When getting an aftermarket tune on a Roush or Whipple Supercharged 2015+ mustang an aftermarket IAT sensor is required as the one that comes with the kit isn't readable with aftermarket tuning software. The Lethal Performance IAT sensor kit with harness and brass temperature sensor is a plug and play setup making install a breeze.

Lethal Performance Level 1 Fuel System

The Lethal Performance Level 1 2018+ return style fuel system was designed for those looking to make big power as well as have the option to run different fuel types. 

This is a single regulator fuel system which feeds the DI pump and fuel rails from a Y-block. Fuel is then regulated by the Aeromotive fuel pressure regulator on the drivers side and returned back to the fuel tank. 

Fragola pre-assembled PTFE lined hoses are used for the hose routing. The Fragola PTFE hoses not only look good and are easy to install, but they also don't have any fuel weep or smell to them whether you run pump gas or Ethanol based fuels. The PTFE fuel hoses are also covered in a black coating to help prevent the stainless outer braid from rubbing or scratching any part of your vehicle.

Wiring for this system is super easy with the provided Lethal Performance Triple pump fuel wiring harness. Our triple pump wiring harness features high quality wires/components, 3 40amp relays which are all individually fused and the main power from the battery is also protected by a fusible link.

This fuel system will work with gasoline, race fuels and Ethanol based fuels such as E85.
