Why Does My BluePrint Engine Have A High-Volume Oil Pump?
One of the most common questions customers ask is why their BluePrint Engine has higher oil pressure than a factory engine. In many cases, the answer is simple: BluePrint utilizes high-volume oil pumps in many of its engine combinations to help provide consistent oil supply in demanding performance applications.
What Is A High-Volume Oil Pump?
A high-volume oil pump moves more oil through the engine than a standard-volume pump.
This allows the lubrication system to maintain adequate oil supply during:
- Performance driving
- Higher RPM operation
- Larger bearing clearances
- Increased engine loads
Why Does BluePrint Use High-Volume Oil Pumps?
BluePrint Engines are designed for performance applications and are often used in:
- Muscle cars
- Street rods
- Drag racing vehicles
- Street/strip combinations
- High-performance trucks
A high-volume oil pump helps ensure a consistent supply of oil to critical engine components under varying operating conditions.
Is Higher Oil Pressure Normal?
Yes.
Many BluePrint customers report oil pressure that is higher than what they previously observed on older production engines.
Common reasons include:
- High-volume oil pump
- Tighter engine clearances
- Fresh engine components
- Oil viscosity
- Engine temperature
Higher-than-expected oil pressure is often completely normal.
Why Is My Oil Pressure Higher When The Engine Is Cold?
Cold oil is thicker than hot oil.
As a result, it is normal to see:
- Higher oil pressure during startup
- Higher oil pressure before the engine reaches operating temperature
- Lower oil pressure once fully warmed up
Why Does My Oil Pressure Drop At Idle?
Oil pressure naturally decreases as:
- Engine RPM decreases
- Oil temperature increases
This is normal as long as:
- Oil pressure remains stable
- Pressure increases with RPM
- No abnormal engine noise is present
Does A High-Volume Pump Mean Higher Horsepower?
No.
The oil pump's purpose is lubrication and oil control.
A high-volume pump is not intended to increase horsepower.
Should I Change To A Standard Volume Oil Pump?
No.
BluePrint does not recommend changing oil pump specifications unless directed by Technical Support or Engine Engineering.
The oiling system was designed and tested as a complete package.
What Should I Watch For?
You should investigate the engine if you observe:
- Sudden loss of oil pressure
- Oil pressure dropping to zero
- Excessive pressure fluctuations
- Unusual engine noise
- Oil pressure that does not respond to RPM changes
Frequently Asked Questions
My BluePrint Engine Has More Oil Pressure Than My Old Engine. Is That Normal?
Yes. Many BluePrint Engines use high-volume oil pumps and tighter internal clearances than older production engines.
Why Does Oil Pressure Change As The Engine Warms Up?
Oil viscosity changes with temperature, causing oil pressure to decrease as the oil reaches operating temperature.
Is High Oil Pressure Bad?
Not necessarily. Higher oil pressure is often normal on a fresh performance engine equipped with a high-volume oil pump.
Should My Oil Pressure Increase With RPM?
Yes. Oil pressure should normally increase as engine speed increases.
