Calculate optimal turbocharger size, compressor requirements, and performance gains for your engine build.
Enter your engine's basic specifications to calculate airflow requirements.
Define your target power output and desired characteristics.
Configure your turbocharger preferences and setup details.
Based on your inputs, here are the recommended turbo specifications:
• Compressor: 71mm • Turbine: 60mm • Max Power: 550HP
Best for: Street/Strip 2.0L-3.0L engines
• Compressor: 63mm • Turbine: 58mm • Max Power: 500HP
Best for: Quick spool, responsive street
• Compressor: 58mm • Turbine: 58mm • Max Power: 600HP
Best for: Drag racing, high boost
| Model | Compressor (mm) | Turbine (mm) | Max Power | Spool RPM |
|---|---|---|---|---|
| Garrett GT2860RS | 60 | 53 | 320 HP | 2800 RPM |
| BorgWarner EFR 6258 | 58 | 52 | 400 HP | 2900 RPM |
| Precision 5558 | 58 | 55 | 550 HP | 3200 RPM |
| Garrett GTX3582R | 82 | 68 | 750 HP | 3800 RPM |
• Upgrade fuel system to support calculated airflow
• Consider forged internals for boost over 20 PSI
• Install wideband O2 sensor for proper tuning
• Use high-quality oil and frequent changes
• Consider methanol injection for higher boost safety
Calculate exact airflow requirements based on engine displacement, RPM, and volumetric efficiency.
Determine optimal pressure ratio for your desired boost level and elevation.
Visualize compressor efficiency islands and operating points for various turbo models.
Understand how turbine size and A/R ratio affect turbo response and powerband.
Ensure proper matching of turbo, intercooler, exhaust, and fuel system components.
Calculate safe operating limits and provide recommendations for reliable performance.
