Renault are working with Ilmor, not just Red Bull/Tag Heuer, they have made a big step forward. Honda have made an even larger step forward and they still say they have compromised max power/compressor size for better packaging for aero efficiency.
Yes, Mario Ilien is the IL of Ilmor. TAG is paying the bills. I'm speculating that Renault still builds the shortblocks, but puts Ilmor spec pistons in them to match the valve angles/combustion chamber design of the Ilmor heads.
Based on the results of the Chinese Grand Prix, Red Bull now has one of the most powerful engines out there. Kvyat and Ricciardo were definitely factors throughout the race yesterday, finishing 3rd and 4th. Meanwhile, Button and Alonso finished 12th and 13th with the "improved" Honda. Honda still has much work to do.
