Review SCAT Pro Comp Lightweight Crankshaft fits 9000

The **SCAT 9351W10 9000 Pro Comp Crankshaft** represents the pinnacle of high-performance engineering, meticulously crafted to elevate the power, durability, and responsiveness of your engine to unprecedented levels. Designed for serious racers, drag enthusiasts, and performance tuners who demand nothing less than elite reliability and brute-force output, this crankshaft is a masterpiece of precision machining and advanced metallurgy. Built from **4340 alloy steel**, a material renowned for its exceptional strength-to-weight ratio and fatigue resistance, this crank is forged to exacting standards and then **carburized and hardened** to achieve an optimal balance of toughness and wear resistance. The **9000 Pro Comp** designation underscores its cutting-edge construction, featuring **fully counterweighted main journals** and **optimized rod journals** to minimize vibration, reduce stress, and enhance overall engine smoothness critical for high-RPM applications where stability is paramount.

The **9350 series** is particularly celebrated for its **balanced performance across a wide RPM range**, making it an ideal choice for both street-strip builds and high-revving forced-induction setups. The **W10** variant incorporates **10-degree rod angles**, a design choice that further refines power delivery by improving piston-to-wall contact and reducing friction, while also allowing for a more compact engine package. Each journal and main bearing surface is **polished to a mirror-like finish**, ensuring minimal oil consumption and maximum efficiency in lubrication, which is essential for engines pushing beyond factory limits. The crankshaft s **integrated counterweights** are dynamically balanced to eliminate harmful harmonics, a feature that not only extends the life of your engine s supporting components but also allows for aggressive tuning without the risk of catastrophic failure.

Beyond its structural integrity, the **9351W10 9000 Pro Comp** is engineered with **modern machining techniques**, including **CNC milling and grinding**, to achieve flawless dimensional accuracy. This level of precision ensures a perfect fit with high-performance pistons, rods, and bearings, allowing for optimal compression ratios and power output. Whether paired with a **nitrous-injected V8**, a **turbocharged inline-six**, or a **supercharged small-block**, this crankshaft delivers the robustness needed to handle extreme loads while maintaining reliability. SCAT s reputation for **race-proven durability** is further reinforced by the **9000 Pro Comp s** use in professional racing circuits, where it has consistently outperformed conventional cranks under the most demanding conditions. For those seeking to push their engine to its absolute limits whether for drag racing, circle-track competition, or high-performance street applications the **SCAT 9351W10 9000 Pro Comp Crankshaft** is the undisputed benchmark of performance engineering, combining raw power potential with the refinement needed to make every revolution count.

### **Pros and Cons of buying a SCAT 9351W10 9000 Pro Comp Crankshaft**

1. **High Performance Potential** The 9000 Pro series is designed for high RPM and extreme durability, making it suitable for forced induction builds, drag racing, or high-revving applications. The forged steel construction ensures strength at high RPMs, reducing the risk of failure under heavy loads.

2. **Precision Machining** SCAT cranks are known for tight tolerances and balanced construction, which improves engine smoothness and longevity. The 9351W10 (likely a 4.000-inch stroke, 350-degree rod angle) is optimized for power output in V8 engines, particularly in muscle cars and performance trucks.

3. **Durability and Longevity** Forged from high-quality steel, this crank is built to withstand extreme stress, including high torque from superchargers, turbochargers, or nitrous systems. Properly paired with a strong engine, it can last for decades with proper maintenance.

4. **Compatibility with Aftermarket Parts** The 9000 Pro series is designed to work well with other high-performance components, such as forged rods, pistons, and connecting rods from SCAT or other reputable manufacturers. This makes it a versatile choice for builders.

5. **Warranty and Support** SCAT offers strong warranties on their cranks, providing peace of mind for serious builders. Their technical support and reputation in the performance market add credibility.

6. **Reduced Vibration** The balanced design minimizes engine vibration, improving drivability and reducing wear on other components.

7. **Customization Options** SCAT offers various crankshaft configurations (different stroke lengths, rod angles, and journal sizes), allowing builders to fine-tune their engine for specific applications.

---

1. **High Cost** Forged cranks like the 9000 Pro series are significantly more expensive than cast cranks. The price can range from **$1,500 to $3,000 **, depending on the configuration and additional features (e.g., counterweights, grinding options). This makes it a substantial investment for even mid-tier builds.

2. **Requires Professional Installation** While not impossible for experienced DIYers, installing a forged crank often requires specialized tools, precise machining, and expertise. Improper installation can lead to catastrophic failure. Many builders opt for professional engine rebuilding services, adding to the cost.

3. **Not Necessary for Stock or Mild Builds** If you re running a naturally aspirated engine with stock or mild modifications (e.g., camshafts, headers), a forged crank may be overkill. A well-maintained stock or cast crank could suffice, saving money without sacrificing performance.

4. **Weight Considerations** Forged cranks are heavier than cast counterparts, which can slightly reduce acceleration in high-horsepower applications. However, this is rarely a significant issue unless building for extreme drag racing or street legal high-performance.

5. **Maintenance and Storage Requirements** Forged cranks should be stored properly to prevent corrosion. If not used immediately after purchase, they may require protective coatings or storage in a dry environment.

6. **Potential for Overbuilding** Some builders may purchase a forged crank without fully considering whether their engine s other components (e.g., rods, pistons, block) can handle the stress. Mismatched parts can lead to premature failure.

7. **Lead Time and Availability** High-demand cranks like the 9000 Pro series may have long lead times, especially if ordering custom grinding or special configurations. This can delay engine builds.

### **Conclusion**

The **SCAT 9351W10 9000 Pro Comp Crankshaft** is one of the best choices for serious builders targeting **high RPM, forced induction, or extreme power applications**. Its forged construction, precision machining, and compatibility with aftermarket parts make it a reliable upgrade for engines pushing **600 HP or more**. However, the high cost, installation complexity, and potential overbuilding risks mean it s not suitable for every project.

If you re running a **naturally aspirated engine with moderate power goals (under 500 HP)**, a stock or cast crank may be sufficient. But if you re building a **supercharged, turbocharged, or nitrous-powered engine** with ambitions for **high RPMs and longevity**, the 9000 Pro series is a **strong recommendation** provided the rest of the engine is properly matched.

---

### **Recommendation**

- You re building a **high-performance V8** (muscle car, truck, or race engine) with **forced induction or nitrous**.

- Your engine will operate at **high RPMs consistently** (e.g., 7,000 RPM).

- You re using **forged rods, pistons, and connecting rods** for a balanced build.

- You have access to **professional installation** or the expertise to install it correctly.

- You re willing to invest in a **long-term, durable component** rather than a budget option.

- You re on a **tight budget** and only need mild performance gains.

- Your engine will remain **naturally aspirated with stock or minimal modifications**.

- You lack the **skills or tools** for proper installation.

- You re unsure whether the rest of your engine can handle the stress of a forged crank.

For most **serious builders aiming for serious power**, the **SCAT 9000 Pro series is a worthwhile investment** just ensure the rest of the engine is properly matched to avoid unnecessary risks.
