GlowShift Tinted 60 PSI Boost Gauge Kit
The GlowShift Tinted 60 PSI Mechanical Boost Gauge is designed to monitor turbo boost pressure for diesel trucks. It uses a 2-1/16″ (52mm) analog gauge with a black dial and illuminated red needle for quick readings at a glance. The gauge features a tinted lens, matte black trim ring, and aluminum housing for durability in harsh environments. It offers seven solid color modes plus two color cycle options to match factory dash lighting or create a custom interior look. Color options include blue, red, green, teal, purple, white, and yellow. A dimmer wire connected to the headlight switch reduces brightness by about 30% when headlights are on. The kit includes mechanical hose and 1/8-27 NPT fittings for installation in diesel turbo systems.
Key considerations for diesel use: mechanical gauge requires no power source beyond the sensor; ensure compatible fittings for your turbo plumbing; the multi-color display helps maintain legibility in various lighting conditions. The 0–60 PSI range covers most common diesel turbo boost scenarios, though extreme builds may exceed this range.
Hewitt Industries 50 PSI Universal Turbo Gauge Kit
The Hewitt Industries Turbo Boost Gauge Kit provides a 0–50 PSI range suitable for many diesel turbo setups. The kit includes fittings and an 8′ pressure hose, simplifying installation on trucks with remote mounting or tighter engine bays. This gauge emphasizes diagnostic utility and protection of turbo components by offering reliable analog readings that help detect boost leaks, overboost conditions, and turbo lag. Its universal fittings support a wide range of diesel engines and aftermarket turbo configurations.
Pros for diesel owners: straightforward installation with included hose and fittings; robust construction for under-hood use; clear analog readout aids quick judgment during driving. Consider whether a broader range (60 PSI) is needed for high-boost applications or if 50 PSI covers your typical operating window.
GlowShift Tinted 7 Color 30 PSI Boost/Vacuum Gauge
This GlowShift 30 PSI Boost/Vacuum Gauge tracks both boost pressure and vacuum levels for diesel engines with turbo or supercharged setups. The dual-capability instrument reads 0–30 PSI for boost and -30 to 0 inHg for vacuum, giving a broader view of engine performance. The gauge has a black dial, illuminated red needle, tinted lens, and a multi-color display that can match interior lighting. The dimmer wire connection reduces brightness with headlights on, maintaining readability in low-light conditions. This kit is a versatile option for users balancing boost monitoring with vacuum diagnostics.
Considerations for diesel users: a 30 PSI boost range is suitable for many stock-to-mild-tune engines; vacuum measurement is helpful for turbocharger control and wastegate behavior. If you expect higher boost, a 60 PSI gauge may be more appropriate.
GlowShift White 60 PSI Boost Gauge Kit
The GlowShift White 60 PSI Boost Gauge Kit provides a bright, readable display for diesel applications in challenging lighting. The white dial with a clear lens and illuminated red needle ensures strong contrast in daylight and night driving. It comes with the same seven solid color modes and two color cycle modes to align with interior lighting. The kit includes a mechanical hose and fittings, enabling robust installation in turbocharged engines. As with other GlowShift products, the dimmer wire connection allows brightness adjustment when headlights are on, reducing glare and eye fatigue during night driving.
Diesel-specific notes: a 0–60 PSI range accommodates typical turbocharged diesel systems; ensure your truck’s manifold pressure and tuning stay within the gauge’s range to avoid misreads during heavy towing or high-boost conditions.
GlowShift Black 7 Color 60 PSI Diesel Kit with 3 Gauges
This GlowShift 3-Gauge Diesel Kit combines a 60 PSI boost gauge with two additional sensors—an exhaust gas temperature (EGT) gauge and a transmission temperature gauge. The triple gauge cluster provides a comprehensive view of engine health, helping to monitor turbo performance, exhaust temperatures, and transmission operating conditions. The gauges use a black dial, clear lens, and multi-color display with illuminated red needles for quick readability. Includes 2-1/16″ (52mm) gauges and a dimmable backlight for day or night use. Suitable for owners who want a compact, all-in-one monitoring solution for diesel engines under load.
Key factors for diesel owners: simultaneous monitoring of boost, EGT, and transmission temperature enables proactive maintenance. However, the complexity of wiring and sensor placement should be planned to ensure reliable readings and avoid sensor interference with other engine components.
MaxTow Double Vision 60 PSI Boost Gauge Kit
The MaxTow 60 PSI Boost Gauge Kit features a dual readout system that combines analog and digital displays. The blue LED backlit dial provides strong legibility in all lighting conditions, while the digital readout supplements the traditional needle display for precise boost values. The kit includes an electronic pressure sensor, enabling a more modern installation with potentially better signal stability. The 0–60 PSI range covers a broad spectrum of diesel turbo setups, including moderate performance upgrades. Daytime and nighttime dimming modes improve visibility across driving conditions.
Practical considerations: digital readouts can offer precise boost values during tuning and diagnostics; ensure the sensor location is suitable for the vehicle’s under-hood layout to avoid signal interference or heat exposure. This kit is a solid option for those who want both classic analog feel and digital precision in one gauge.
Buying Guide: Key Purchase Considerations for Diesel Boost Gauges
- Gauge type and range: Analog gauges are simple and immediate, while digital or dual-readout gauges provide precise numeric values. For most diesel turbo setups, a 0–60 PSI range is suitable; consider 0–50 PSI if you have lower boost configurations or stock engines.
- Display readability: Look for high-contrast dials, tinted or clear lenses, and color options that match your interior lighting. Dimmer functionality helps during night driving when glare is a concern.
- Sensor and installation: Mechanical gauges rely on sensors and hoses, whereas electronic gauges use sensors connected to the ECU or sensor ports. Ensure compatibility with your engine bay, including NPT fittings and hose length.
- Durability: Diesel applications can expose gauges to heat, dust, and vibration. Choose gauges with sturdy housings (aluminum) and protective lenses.
- Multigauge kits: Some kits combine boost with EGT and transmission temperature, offering broader monitoring. Consider whether you want an all-in-one setup or separate gauges for flexibility.
- Wiring and installation: Gauge kits may include wiring harnesses, dimmer wires connected to headlights, and mounting hardware. Assess whether professional installation is advisable based on your vehicle, especially if wiring runs near hot or moving components.
- Brand support and compatibility: Reputable brands often provide extensive documentation, sensor compatibility lists, and customer support. Check for fitment with your vehicle year, make, and model, particularly for diesel applications and aftermarket turbo setups.
- Aesthetic integration: Color modes and backlighting can enhance the interior look. Choose a gauge that complements your dashboard and any existing gauge cluster styling.
- Maintenance and calibration: Some mechanical gauges may require calibration updates or hose replacements over time. Electronic gauges may need software or firmware updates in certain models.
