Product Overview
Depo Racing 52mm Boost PSI Gauge with Peak Function
Keep a close eye on your engine’s boost pressure with the Depo Racing Boost PSI Stepper Motor Gauge Peak 52mm – PK-SC5201B(PSI).
A boost gauge is one of the most important instruments for a modified turbocharged or supercharged vehicle. It allows the driver to monitor manifold pressure and identify unexpected changes in boost behaviour that could indicate boost leaks, wastegate issues, incorrect boost control or other problems within the forced-induction system.
The Depo Racing PK-SC Series gauge combines accurate monitoring with an attractive performance-focused interior design.
-30 inHg to +30 PSI Measuring Range
The gauge displays both vacuum and positive boost pressure across a range of:
-30 inHg to +30 PSI
This makes it suitable for a wide variety of petrol turbocharged and supercharged performance applications.
The clear analogue display makes it easy to see how boost pressure changes during acceleration, cruising and throttle lift.
Responsive Stepper Motor Operation
The Depo Racing PK-SC boost gauge uses stepper motor gauge technology to deliver smooth, responsive needle movement.
Fast gauge response is particularly valuable on performance vehicles where boost pressure can rise rapidly under load.
The result is a performance gauge suited to both tuned road cars and vehicles used for track or motorsport applications.
Peak Boost Function
The integrated peak function allows the gauge to record the highest boost pressure reached.
This is particularly useful when tuning or diagnosing a vehicle because the driver does not have to continuously watch the gauge during hard acceleration.
After a run, the recorded peak boost value can be checked to help determine whether the turbocharger and boost control system are operating as expected.
Boost Warning Function
The PK-SC Series also incorporates a warning function, helping the driver identify when boost pressure reaches a predetermined level.
Monitoring excessive or unexpected boost pressure is particularly important on modified vehicles where ECU tuning, upgraded turbochargers, boost controllers or wastegate modifications may increase manifold pressure beyond factory specifications.
Seven-Colour LED Illumination
Customise the appearance of your interior with seven available illumination colours:
- White
- Green
- Red
- Yellow
- Sky Blue
- Purple
- Blue
This provides greater flexibility when matching the gauge to your factory dashboard lighting, aftermarket instruments or custom interior.
Smoked Lens & Performance Styling
A smoked lens, black face and chrome-style rim give the Depo Racing 52mm boost gauge a clean performance appearance.
The compact 52mm diameter is one of the most common aftermarket gauge sizes, making it suitable for many:
- Dashboard gauge pods
- A-pillar pods
- Centre console mounts
- Single gauge cups
- Triple gauge holders
- Custom dashboard installations
Always confirm the mounting aperture and installation space before ordering.
Suitable for Turbocharged & Supercharged Cars
The Depo Racing boost gauge is a universal performance component rather than a vehicle-specific replacement part.
It may be used on many turbocharged and supercharged vehicles when installed correctly.
Typical applications include performance vehicles from manufacturers such as:
Audi, BMW, Ford, Honda, Hyundai, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Renault, SEAT, Skoda, Subaru, Toyota, Vauxhall, Volkswagen and Volvo.
Compatibility depends on the vehicle’s engine, boost/vacuum source, electrical system and installation method.
Professional installation is recommended if you are unsure how to connect an aftermarket boost pressure gauge.

Why Install a Boost Gauge?
A boost gauge allows the driver to monitor the pressure produced by a turbocharger or supercharger.
Changes in boost pressure can sometimes help identify issues such as:
- Boost leaks
- Split intercooler hoses
- Wastegate problems
- Boost control solenoid faults
- Incorrect boost controller settings
- Overboost conditions
- Turbocharger performance issues
- Changes following ECU remapping
It is particularly useful on tuned cars where boost pressure has been increased above the manufacturer’s original calibration.
Ideal For
The Depo Racing 52mm PSI boost gauge is suitable for:
- Turbocharged road cars
- Supercharged vehicles
- ECU remapped vehicles
- Stage 1 / Stage 2 tuned cars
- Upgraded turbo applications
- Track cars
- Motorsport builds
- Performance project cars
- Custom dashboard installations
- Modified Japanese cars
- Modified European cars
Important Fitment Information
This is a universal aftermarket performance gauge and is not restricted to a particular make or model.
Before ordering, confirm:
- Your vehicle uses a 12V electrical system.
- A suitable boost/vacuum pressure source is available.
- You have sufficient space for a 52mm gauge.
- The supplied connections are appropriate for your installation.
- The required pressure range is suitable for your vehicle.
Vehicles producing more than approximately 30 PSI boost pressure require a gauge with a higher measuring range.
Professional installation is recommended.
