Digital C/C Gauge Dunlop Style

The Digital C/C Gauge Dunlop Style by Longacre is an essential diagnostic instrument for serious automotive enthusiasts, race teams, and professional mechanics who demand precision cylinder-to-cylinder pressure readings. This digital gauge system eliminates the guesswork from engine tuning and troubleshooting by providing real-time compression data that directly informs critical decisions about engine health and performance optimization.

Built on Longacre's proven digital gauge platform, this compression tester combines a robust sensing element with clear digital readout technology to capture pressure variations that analog gauges often miss. The Dunlop-style configuration allows seamless integration into your existing shop setup, while the digital display eliminates parallax error and provides crisp, repeatable readings across multiple test cycles. The durable construction makes it portable enough for trackside diagnostics yet rigid enough to withstand the repeated thermal cycling and vibration inherent in engine testing environments.

Whether you're diagnosing a cold-start issue, verifying ring seal after a rebuild, or validating carburetor adjustments on a high-performance engine, accurate compression measurement is non-negotiable for peak reliability and power output. This gauge is specifically designed for naturally aspirated and carburetor engines, ensuring that you have the right tool for your performance needs.
