RedLine Gauge 2-1/16in Boost -30/30psi

The RedLine Gauge 2-1/16in Boost -30/30psi from QUICKCAR RACING PRODUCTS is engineered for serious marine operators and performance boaters who demand real-time boost pressure monitoring. Whether you're running a supercharged inboard, a turbocharged outboard, or any high-performance engine setup, this compact boost gauge delivers the precision instrumentation you need to maintain optimal fuel mapping and engine health underway. Built for harsh saltwater and freshwater environments, it serves as an essential diagnostic tool for performance-focused captains.

Featuring a 2-1/16-inch diameter face, the RedLine gauge reads from -30 to +30 PSI, capturing both vacuum and positive boost conditions across the full operating envelope. The analog needle design ensures instant visual reference without electronic lag, critical when monitoring engine load during acceleration or altitude changes. QUICKCAR's RedLine series is known for robust construction and reliability under vibration-heavy marine conditions—the sealed housing protects internal components from salt spray, humidity, and fuel vapor exposure that would compromise lesser instruments.

This gauge integrates seamlessly into existing instrument panels or custom gauge clusters via standard mechanical pressure transducer fittings. It's ideal for boats equipped with forced-induction engines or for owners performing engine diagnostics during tuning sessions. The compact 4.5 x 4 x 5.5-inch form factor fits tight dash spaces, and at just 0.65 pounds, installation requires no structural reinforcement. Whether you're monitoring fuel system pressure, manifold boost, or transmission line pressure, the -30/30 PSI range covers most recreational and light commercial marine powerplant applications.
