Frequently Asked Questions
How accurate is this estimate?
This is a simplified power-based sizing estimate (Inducer Size = 2.147 x sqrt(Target Horsepower)), calibrated against a single published reference point. Real turbo selection requires matching a specific compressor map (airflow vs. pressure ratio vs. efficiency) to your exact engine and goals -- treat this as a rough starting point, not a substitute for consulting the manufacturer compressor maps or a professional tuner.
