APPLICATIONS

  • Complies with the FIA regulation.
  • Especially blended for supercharged engines of Groups A, N and Proto cars.
  • ELF TURBO PLUS allows to optimise supercharged pressure and ignition timing thanks to a selection of petroleum streams which present a strong resistance to pinking on supercharged engine. Furthermore the oxygen compounds in most cases improves the volumetric efficiency of the engine.

RECOMMENDATIONS

  • The best mapping concerning air/fuel equivalence ratio (1.25 to 1.30), supercharging pressure and ignition advance will give optimum results. The difficulty is that on turbocharged engines, these three parameters are fundamental and completely dependant to each other.
  • Air/fuel ratio must absolutely be checked and re-tuned if necessary because of the extremely high density and oxygen content of ELF TURBO PLUS compared to the usual commercial fuel quality.
  • In order to maintain the original properties, and according to Health and Safety regulations of commercial fuels, this gasoline shall be handled and stored in a cool place and always maintained in tightly shut drums.
