    Cylinder head work for Triumph, Jaguar, Ford rally engines

  • Testing work independently done by world leading head specialists.
  • Models supported:- GT6/TR6 engine designed to overcome original design faults
    - and run on modern 95 unleaded octane with no loss in torque and no signs of pinking.
  • Camshaft redesign, possibility of running low grade 91/92 octane fuels.
  • Jaguar XJS engine 24V - 6, torque increase of up to 20% on STANDARD engine.
  • Ford 16V Zetec SE and Duratec engines for rally cars. To order only.

    A Triumph engine dev program was revived as of Autumn 2007 with a view to getting 12-15bhp/L more for road cars.
    This has largely worked.
    Engines currently deliver 15bhp more than previously on the same configuration, this means one of our engines delivers up to 10% more torque than any other tuner can manage, over a typically far flatter delivery curve.

  • We have NEVER had one of our engines fail, even on standard exchange road engines.
