Surveastmemõõturit kasutatakse selleks, et tagada, et silindris ülemäärast rõhku ei tekiks, kui surveastet muudetakse turboülelaaduriga autol OEM-standardist kõrgemale tasemele.
A boost gauge is used to ensure excessive pressure is not being generated when boost pressure is being modified to levels higher than OEM standard on a production turbocharged car.
