At SP TAKEGAWA, in order to optimize the amount of oil pumped to each part of the engine, the oil pressure, and the oil level of each part, we have increased the oil volume by approximately 50% compared to the stock one.
By circulating the appropriate amount of oil, it is possible to reduce the burden on drive parts, improve cooling performance, and ensure an oil film on lubricated parts.
Furthermore, by incorporating a relief valve function into the oil pump body, hydraulic control is possible, reducing the burden on the engine due to increased oil pressure and achieving stable oil circulation.
Test results when the oil pump discharges too much
The test results show that if the discharge amount is increased too much, the amount of oil discharged by the oil pump will be greater than the amount of oil returned to the crankcase.
As a result, we have confirmed that there is a risk that the oil level will drop too much at high speeds, causing an air trap condition.
This product is an assembly product that includes an oil pump driven gear, so it can be easily installed by simply replacing it with the genuine oil pump.
This product is an assembly product that incorporates the oil pump driven gear and fixing pin, so it can be easily installed by simply replacing it with the genuine oil pump, without the need for diversion, disassembly, or assembly from the genuine oil pump.
In addition, there is no need to reuse genuine parts or check for wear or damage, and you can replace them with new parts.
Increase in the thickness of the oil pump plate and the number of bolts connecting the body and plate
If the oil pressure is increased by increasing the discharge volume compared to the stock oil pump, oil leaks from the gap between the oil pump body and the oil pump plate at high rotation speeds, making it impossible to circulate the proper discharge volume.
The SP Takegawa super oil pump has an increased number of bolts connected to ensure stable oil pressure even at high rotation speeds. (Number of bolts: 1 genuine, 5 made by Takekawa)
In addition, increasing the plate thickness increases rigidity and eliminates oil leaks at high speeds.
Adoption of a relief valve function that enables hydraulic control. Patent pending
The SP Takegawa Super Oil Pump has a discharge volume approximately 50% higher than the stock, and in order to ensure oil pressure during unstable idling and to cope with changes in oil pressure due to increased rotation, the oil line is equipped with a relief valve function that opens only when a certain oil pressure is reached.
This suppresses the excessive rise in oil pressure when the rotation increases, which occurs when the engine is cold, and prevents damage to the drive section and seals.
Furthermore, when the engine is running at high speeds, it does not discharge more oil than necessary, reducing power loss and stabilizing the oil level.
*R.Crankcase cover gasket is not included. You will need it when replacing it, so please purchase it separately. The shape and genuine part number of the R. crankcase cover gasket differ depending on the vehicle. Please check the vehicle before purchasing.
