FAQ
Does this gauge require a power source?
No. The gauge is fully mechanical and runs solely on boost pressure, eliminating the need for any electrical connection.
Can I use this gauge on a naturally aspirated engine?
While designed for turbocharged applications, the gauge will read pressure from any boost source, but it will not provide useful data on a naturally aspirated engine.
What type of bulb does the gauge use?
The gauge uses a standard incandescent bulb with optional red and green covers for customized lighting.
Is the gauge compatible with all turbocharger sizes?
Yes. The mechanical line and fittings can be adjusted to suit a wide range of turbocharger boost pressures.
How difficult is the installation?
Installation is straightforward with the included hardware and detailed guide; most users can complete it in under an hour.
