GlowShift Black 7 Color 60 PSI Turbo Boost Gauge Kit
This gauge monitors boost pressure for turbo or supercharged diesel engines. It reads 0-60 PSI with a 2-1/16″ (52mm) diameter and features a black dial, illuminated red needle, tinted lens, and aluminum housing. Seven solid color modes plus two color cycles allow interior matching. Best for diesel trucks needing a bold, configurable look; however, it requires proper mechanical installation with 1/8-27 NPT fittings.
GlowShift Tinted 7 Color 60 PSI Turbo Boost Gauge Kit
Designed for diesel trucks, this mechanical boost gauge covers 0-60 PSI with a tinted lens and multi-color display. The seven color modes help you match factory lights or create a distinctive interior. A caution: proper dimming integration is needed to ensure visibility at night, and mounting hardware must be secured during installation.
GlowShift Black 7 Color 60 PSI Turbo Boost Gauge Kit
This kit mirrors the Black 60 PSI theme with a black dial and clear lens. It offers seven color modes and two cycle modes for interior customization. Best for diesel builds prioritizing a crisp, legible display; limitation: some users may prefer a fully digital readout for data logging.
Auto Meter Ultra-Lite 2-1/16″ 0-15 PSI Mechanical Boost Gauge
This gauge provides traditional incandescent lighting with mechanical operation and no electrical system requirement for gauge operation. It covers 0-15 PSI, suitable for builders or enthusiasts needing precise, simple boost readings without electrical wiring. Better for typical street setups than extremely high-boost diesels; installation should ensure a clean sensor location.
BOSCH SP0F000050 Style Line 2″ Mechanical Vacuum/Boost Gauge
Compact 2″ gauge with a 0-20 PSI boost range and a 270-degree sweep. It includes a black dial and bezel, with a removable mounting panel. Best for budget-focused buyers needing a straightforward mechanical gauge; caution: 2″ installations may require compatible dash space and mounting hardware.
GlowShift Black 7 Color Diesel Truck 3 Gauge Kit
This three-gauge kit includes 60 PSI Boost, 1500°F EGT, and Transmission Temperature readings in a single cluster. It provides a compact way to monitor three critical metrics on a diesel engine. Choose this if you want a small, integrated set; avoid if you need higher boost range visibility or digital logging options, as it relies on analog readouts.
GlowShift 3in1 Analog Boost Gauge With Digital Pyrometer
Combines analog boost (0-60 PSI) with digital EGT (200-2200°F) and temperature readouts. The 2-3/8″ gauge features multiple color modes and dimming options. Best for users who want a single multi-parameter display; limitation: more complex wiring and setup compared to single-gauge systems.
GlowShift White 7 Color 60 PSI Boost Gauge Kit
This kit offers a white dial with seven color modes, including two color cycles. It’s best for drivers who prefer high daytime contrast and a bright interior style. Caution: white-dial visibility can be impacted by glare in very bright cabins; ensure the chosen color mode reduces glare during daytime driving.
Buying Guide
- Boost range and gauge type: Diesel engines typically operate within 0-60 PSI for boost gauges; select a mechanical gauge for reliability and simple wiring, or a digital/analog combo if you want multi-parameter readouts.
- Display visibility: Multi-color options help match interior lighting and improve daytime/nighttime legibility. Consider tinted or white dials based on your dashboard aesthetics and glare conditions.
- Installation considerations: Check sensor fittings (1/8-27 NPT vs other threads) and gauge diameter (2-1/16″ vs 2″). Mechanical gauges require proper fittings; electrical gauges need wiring access to power and dimming wires.
- Additional metrics: If monitoring more than boost, consider 3-gauge kits or a combo (boost + EGT + transmission temp) for a broader engine picture. Ensure compatibility with your vehicle’s dash space.
- Durability and lighting: Aluminum housings and sealed lenses improve durability in harsh environments. Dimmer compatibility with headlights reduces glare and preserves readability at night.
FAQ
- What is the typical boost range for these gauges? Most diesel gauges cover 0-60 PSI, with some models offering lower ranges like 0-15 PSI for performance tuning.
- Do these gauges require electrical installation? Some gauges are fully mechanical, while others use electrical connections for lighting and sensors. Follow manufacturer installation instructions.
- Can I mix gauges from different brands in one cluster? Yes, but ensure similar dial sizes (2-1/16″ or 2″) and compatible mounting hardware for a cohesive look.
- What does “multi-color” display help with? Multi-color modes let you match dashboards, improve visibility in various lighting, and create a preferred interior ambiance.
- Is a digital readout necessary for monitoring engine health? Digital or combo gauges provide more data at a glance; for basic boost monitoring, a mechanical gauge is usually sufficient and reliable.
- Are there any cautions when installing these gauges? Ensure proper sealing of fittings to avoid leaks, proper sensor placement, and secure wiring to prevent damaged wiring or dashboard interference.
