Although the split was only made official in Singapore, the McLaren team boss says that the team are actually only two weeks behind schedule.
"Obviously for a while we will have to work 24 hours a day, seven days a week to compensate for the two weeks that have passed since the optimal decision-making time," the Frenchman is quoted as saying by international media reports.
"But it is quite possible to catch up those two weeks."
Boullier said that any delay will also be compensated by Renault's better engines next year.
"Next year there will be no compromises," he insisted.
"Of course, we do not have experience with Renault's power unit, unlike some other teams, so we will have to get used to that. But we believe in our engineers."
Furthermore, he said that development of McLaren's Honda-powered 2017 car will continue.
"We will increase our workload to compensate for the delay, and then return to our normal schedule of work," said Boullier.
"The transition to another manufacturer of power units will not change our approach. There will be no revolution, only evolution."
McLaren have picked up 17 points with Honda in 2017.
