StreetFighter Gen 5 3.8L Supercharger Kit (2015-17) – SUPPLY ONLY

StreetFighter is proud to offer the new 3.8L GEN 5 Whipple supercharger package to suit the S550 Mustang GT 2015-2017.

This package has evolved from our race and road experience utilising both the older style 2.9L supercharger to using the latest 3.0L supercharger. Our testing, development and ultimately our results paved the way to refining a 3.8L supercharger package for 2015-2017 Mustang GT owners.

While other companies still rely on and offer the older style 3.0L package, StreetFighter has developed the latest direct fit package combined with tuning calibrations specifically suited to our Australian conditions and fuels.

The StreetFighter 3.8L supercharger package is suited for your Australian RHD 2015-2017 Mustang GT.

  • Largest intercooler system on the market, featuring patent pending triple core technology
  • No other upgrades required, just massive power right out of the box
  • Front entry Gen 5 (3.8 litres/3800cc) Whipple twin-screw supercharger that significantly outperforms competitions 2.3L and 2.65L roots-type systems
  • Gen 5 supercharger features new 3×4 rotor combination for increased RPM capacity, large diameter for increased airflow and small leak path, increased helix for optimal sealing
  • 0L is 13% larger than 2.65L roots-type allowing lower power draw and lower discharge temps to flow the same amount of air (more power to the rear wheels)
  • In testing, the 3.8L has a roughly 6% increase in isentropic efficiency compared to the 3.0L.
  • Oversized Crusher™ 150mm inlet for maximum airflow capacity and minimal rotor cavitation
  • Inverted design allows for oversized intercooler core compared to other smaller intercooler cores giving Whipple lower air charge temps which allows more boost and timing to be run on pump fuel
  • Patent pending triple intercooler technology with massive dual 1″ inlet port capacity
  • Massive air-to-water aluminum bar-plate intercoolers (over 55% larger than some competition) offer more cooling than any other positive displacement system available, nothing comes close
  • Massive oversized aluminum intercooler reservoir (over 2 gallons) holds more than double any competitors IC water system allowing longer more consistent power levels vs. competition
  • High flow intercooler pump, nearly double the flow of the standard units others use
  • Whipple superchargers massive oversized intercooled air-bypass system for industry leading reduction of burst knock and incredible fuel economy.
  • 100 lb/hr ( +/- 1%)  matched set  fuel injectors vs stock 17lb/hr stock injectors
  • Exclusive 3×4 rotor combo for significant increase in airflow under the curve than less efficient 4×4 roots
  • Center discharge port for better cylinder-to-cylinder distribution then other twin-screws with cobbled together billet adapters and forward facing discharge
  • Extra plenum volume below intercooler core for far less pressure drop and better use of the increased surface area of the massive intercooler core
  • More boost at the “hit” than any other twin-screw
  • Flat torque curve for incredible acceleration
  • KPM Fuel Systems 900hp or 1500hp high flow fuel module replaces stock pump (optional)
  • Oversized heat exchanger for incredible intercooler water temps, 150% more volume than competition, standard with every kit
