About Turbo Sizing
Proper turbo sizing ensures optimal boost response, power delivery, and efficiency. The calculator considers engine displacement, target power, boost pressure, and RPM range to recommend appropriate turbo specifications. The A/R (Area/Radius) ratio affects spool-up time and top-end power - lower ratios spool faster but limit top-end flow.
