FX Engines Makes Low Profile More Complicated


Low profile engine heads with 6 or 7 or 8 ribs have lower weight than the standard engine head and give a lower CG to make the car more stable on fast tracks. CNC machined from Swiss 7075 T6 and additionally black coated and laser engraved for a stylish look. The cooling heads feature additionally drilled holes from the bottom to reduce the weight. The recessed contact area on the underside of the cooling heads, where the combustion chamber insert fits, has had the color coating machined away to allow for the optimal heat transfer. Temperature conditions dictate the recommendations for various different engine heads:

  • 6 ribs Low air temperature
  • 7 ribs Medium air temperature
  • 8 ribs High air temperature
