Extreme Output V6 Ecoboost

Radical Performance Engines was given the challenge of generating more power through the Ford V6 Ecoboost. RPE met the challenge head on, creating a series of work streams to achieve a higher power output.

Bottom End:

  • Custom RPE cylinder support modification
  • JE 9:1cr forged piston with low friction skirt coating
  • Carrillo forged connecting rods
  • Main bearing upgrade (Tri-metal race bearings)
  • Big end bearing upgrade (Tri-metal race bearing)
  • Motorsport head studs

Top End:

  • Black nitride intake valves
  • Inconel sodium-filled exhaust valves
  • Valve spring upgrade
  • Top hat valve shim upgrade
  • Valve bucket upgrade
  • Custom RPE camshaft reprofile
  • Custom gasflowed cylinder head

Miscellaneous:

  • Latest specification Ni-Resist exhaust manifolds
  • GTX2967r Hybrid turbocharger (Larger 90 Trim Turbine Wheel with a .86ar housing, ported internal wastegate)
  • Custom mapping
  • Rising rate pressure on port injection
  • Bosch style adjustable fuel pressure regulator
  • Tri-metal race bearings fitted for additional load carrying and fatigue resistance

Result:

850hp is achieved with 23 psi (1.58bar) of boost pressure, torque is electronically limited via boost pressure to 636 ft/lb.

Due to a substantially revised valvetrain and turbo setup, an increased RPM limit can be applied (8000rpm) allowing for a higher power output without an increase in torque. This is achieved with less boost pressure.
