Turbo Lag Calculator
Calculate turbo lag based on engine displacement, turbo size, boost pressure, and RPM. Understand how different factors affect turbo response time and spool characteristics.
Step 1: Engine Details
Understanding Turbo Lag
Turbo lag is the delay between demanding power and the turbocharger providing boost. It’s influenced by turbo size, engine displacement, exhaust flow, and RPM. Smaller turbos spool faster but may run out of breath at high RPM.

About Turbo Sizing
Turbo size significantly impacts lag characteristics. Smaller turbos (1-3) spool quickly but limit top-end power. Medium turbos (4-6) offer a balance. Large turbos (7-10) provide high power potential but have noticeable lag.

Turbo Lag Calculation Factors
Lag = f(Turbo Size, Engine Flow, RPM)
Turbo lag is calculated based on the relationship between turbo inertia, exhaust gas energy, and engine RPM. Smaller displacement engines with large turbos experience more lag. Twin-scroll and variable geometry turbos can reduce lag significantly.
