1. What is Vortech Supercharger RPM?

Vortech supercharger RPM refers to the rotational speed of the supercharger impeller, which is calculated based on engine RPM and the pulley ratio between the crank pulley and supercharger pulley.

2. How Does the Calculator Work?

The calculator uses the supercharger RPM formula:

\[ \text{Supercharger RPM} = \text{Engine RPM} \times \frac{\text{Crank Pulley}}{\text{Supercharger Pulley}} \]

Where:

Engine RPM — Engine revolutions per minute
Crank Pulley — Diameter of the crankshaft pulley (inches)
Supercharger Pulley — Diameter of the supercharger pulley (inches)

Explanation: The formula calculates the supercharger speed based on the pulley ratio and engine RPM, determining how fast the supercharger impeller is spinning.

3. Importance of Supercharger RPM Calculation

Details: Calculating supercharger RPM is crucial for proper supercharger operation, preventing overspeed conditions, optimizing boost levels, and ensuring the supercharger operates within its designed RPM range for maximum efficiency and longevity.

4. Using the Calculator

Tips: Enter engine RPM, crank pulley diameter, and supercharger pulley diameter in inches. All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the safe RPM range for Vortech superchargers?
A: Most Vortech superchargers have a maximum safe operating RPM of 50,000-55,000 RPM. Always consult your specific model's specifications.

Q2: How does pulley size affect supercharger performance?
A: Smaller supercharger pulleys or larger crank pulleys increase supercharger RPM, resulting in higher boost levels and increased air flow.

Q3: Can I exceed the maximum recommended supercharger RPM?
A: Exceeding the maximum recommended RPM can cause supercharger failure, bearing damage, and impeller damage. Always stay within manufacturer specifications.

Q4: How often should I check supercharger RPM?
A: Check whenever changing pulley sizes, modifying engine components, or if you suspect boost-related issues in your forced induction system.

Q5: Does supercharger RPM directly correlate with boost pressure?
A: While higher supercharger RPM generally produces more boost, other factors like engine efficiency, intercooling, and airflow restrictions also affect final boost pressure.
