Digital Tachometer with Numeric and Bar Graph Readout
Specifically designed for use in motorcycle powered race car applications, the Viper 1180R can be configured to register up to 20,000 RPMs.  The bright orange backlit display features a numeric and bar graph readout of RPMs.  It also features a shift light that can be configured to flash at a specific RPM.  After each session, the five highest RPMs for the session can be displayed.  The tachometer can be used with 1, 2, 4 and 8 cylinder engines.
Water Temperature Gauge
In addition to displaying RPMs, the unit also displays water temperature – eliminating the need for 2 separate gauges.  It also has a programmable water temperature warning light that can be programmed to flash at a specific temperature.  The tachometer includes a sensor with 1/8 NPT threads for easy installation.  There is an adapter available that splices into your radiator hose – making for an easy connection.
