Why Does My BluePrint Engine Use A Forged Crankshaft?
Many customers ask why certain BluePrint Engines are equipped with forged crankshafts and what advantages they provide compared to cast crankshafts. Forged crankshafts are commonly used in high-performance and racing applications because they offer increased strength and durability under demanding operating conditions.
What Is A Forged Crankshaft?
A forged crankshaft is manufactured by compressing steel under extremely high pressure to create a stronger grain structure than a traditional cast crankshaft.
This process produces a crankshaft that is better suited to handle:
- Higher horsepower levels
- Increased cylinder pressures
- Performance applications
- Power-adder combinations
- Racing environments
Why Does BluePrint Use Forged Crankshafts?
Many BluePrint performance engines are designed for:
- Street performance
- Street/strip use
- Drag racing
- Autocross
- High-horsepower applications
A forged crankshaft provides an added level of durability and reliability in these demanding environments.
What Are The Advantages Of A Forged Crankshaft?
Increased Strength
Forged crankshafts are generally stronger than cast crankshafts and are designed to withstand higher loads.
Benefits include:
- Improved durability
- Increased fatigue resistance
- Better high-load capability
- Enhanced reliability
Better For Power Adders
Forged crankshafts are commonly used in:
- Supercharged engines
- Turbocharged engines
- Nitrous-assisted applications
Higher cylinder pressures increase stress on the rotating assembly, making a forged crankshaft a popular choice.
Improved High-RPM Durability
Performance engines operating at higher RPM levels place additional stress on the crankshaft.
Forged crankshafts are commonly selected for:
- Racing applications
- High-performance street engines
- Engines with aggressive camshaft packages
Are Forged Crankshafts Only For Racing?
No.
While forged crankshafts are popular in racing applications, they are also commonly used in:
- Muscle cars
- Street rods
- Restomods
- Performance trucks
- Street/strip vehicles
Many BluePrint customers appreciate the extra strength and peace of mind they provide.
Can A Forged Crankshaft Increase Horsepower?
Not directly.
A forged crankshaft does not add horsepower by itself.
Its primary advantage is its ability to survive the increased loads associated with higher-performance engine combinations.
Do Forged Crankshafts Require Special Maintenance?
No.
Forged crankshafts do not require special maintenance beyond normal engine maintenance procedures.
Follow:
- Recommended oil changes
- Break-in procedures
- Proper tuning practices
- Recommended RPM limits
to maximize engine life.
Which BluePrint Engines Use Forged Crankshafts?
Many BluePrint Pro Series and high-performance engine combinations utilize forged crankshafts.
Always review the specifications for your exact engine model to determine the rotating assembly components included.
