APPLICATIONS
Complies
with the FIA regulation.
Especially
blended for supercharged engines
of Groups A, N and Proto cars.
ELF TURBO
MAX 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.
But the best results have been achieved
thanks to an original fuel blend
which combine for the best knock
resistance and speed of combustion.
Furthermore the high oxygen content
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 MAX
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.
