BMW Team RLL will head into next month’s Sahlen’s Six Hours of The Glen with additional power underneath its BMW M8 GTEs, following a Balance of Performance adjustment handed out by IMSA.

Confirmed on Wednesday, the pair of factory-entered GT Le Mans contenders have received boost increases through the mid-to-high RPM range, averaging to a 9 kW (12 horsepower) increase.

The additional power has also seen a 6-liter increase in the car’s fuel capacity.

No other changes have been made to the GTLM class, which is not in action at next weekend’s DPi and GT Daytona-only race in Detroit.

While having won January’s Rolex 24 at Daytona, under an event-specific BoP, the RLL BMWs have yet to return to the podium in IMSA WeatherTech SportsCar Championship competition this season.

Connor De Philippi is the highest-placed BMW driver in the GTLM points standings, in fourth.

The German manufacturer announced on Wednesday that it will continue its M8 GTE program in the WeatherTech Championship despite ending its participation in the FIA World Endurance Championship after just one season.
