The FIA Endurance Committee has tweaked the LMP1 Equivalence of Technology (EoT) ahead of September’s FIA WEC Six Hours of Circuit of The Americas.

Gasoline-powered prototypes are likely to use a larger refueling restrictor, following tests conducted on the variation of flow due to higher fuel temperatures.

While the current 25 mm fuel flow for diesel-powered cars will remain unchanged, a larger 25.95 mm opening will be allowed for gasoline LMP1 entries should, on scrutineering day, the weather forecasts predict an ambient temperature higher than 21C (70 F) during the race.

Otherwise, the gasoline-powered cars will revet to a 25.7 mm refueling restrictor, which it had run in the opening two rounds of the FIA WEC.

No changes, meanwhile, have yet to be announced for any possible power or energy adjustments to the LMP1 entries.

Under the new-for-2014 regulations, one adjustment is allowed prior to September’s COTA round, with the technical configuration locked in through the 2015 Le Mans 24 Hours.
