AKS TFSi Oil Pump Balance Shaft Delete Modification
Inside every TFSi EA113 engine, there is an oil pump, inside these are balance shafts. These shafts are designed to help dampen engine sound to reduce cabin or external noise. While the intention was good, its not that effective and has brought a feature to light that can cause issues resulting in catastrophic engine failure. When the balance shafts seize in place, they will stop the oil pump from working, completely starving the engine of oil resulting in your engine being severely damaged.
In house at AKS we start off with a stock oil pump assembly, remove the balance shafts on our mill and modify the oil channels to create a far improved part over stock, erradicating the balance shafts entirely. On high power applications and forged engines this is a highly recommended modification.
There is a lot of discussion online regarding doing this modification in another way, using the old 1.8T 20V oil pumps. Doing that modification requires a lot of work including drilling and tapping oil lines into the block itself. This hassle can be avoided with the AKS balance shaft delete mod as its a simple bolt in job. Minus the worry of balance shafts ever again.
