Frequently Asked Questions
How much power is gained with a turbo?
As a rule, 0.5 bar = +30-50% power, 1.0 bar = +50-80%. This depends on intercooler efficiency, mapping, and engine limitations.
What is turbo lag?
It's the delay between acceleration and turbo pressure buildup. Modern turbos (twin-scroll, VGT, electric) reduce lag to under 0.5 seconds.
How does altitude affect turbo?
Air being less dense at altitude, a naturally aspirated engine loses ~3% power per 1000m. A turbo partially compensates by increasing pressure to maintain density.
