Oil temp is only very remotely related to cylinder head temp (CHT). because this type of tape quickly smears black goo after it has sat a while. Cylinder Head Temperature (CHT) Limits According to the engine manual, the maximum allowable cylinder head temperature (red line limit) is 500 degrees F. Lycoming states flatly that the maximum redline cylinder head temperature limit must never be exceeded. Some aftermarket temperature sensors and overheat warning systems have become available over the years. Originated by Hal Brown in 1972. Designed as a direct replacement for the obsolete AC Delco Thermistor, the CHT-100 uses thermocouple technology for reliable and accurate temperature measurement over the wide range of temperatures experienced in the Corvair air cooled engine. Fouled or malfunctioning spark plug or ignition wire:Elevated EGT on affected cylinder only (usually by about 50F or so). The purpose of the TIT limit is to protect the fast-spinning turbine wheel from blade stretch. EGT is also affected by ignition performance. If you drive an air cooled or in fact any vehicle this CHT gauge will tell you a lot about the state of tune of your engine. Customer Service: 800-861-3192 EGT is a true example of what is actually going on in the combustion of the cylinder. The CHT-100 is an advanced Cylinder Head Temperature Sensor for the Corvair Spyder and Corsa models. What are factors contributing to a higher head temperature? Air cooled aircraft engines (which always have CHT gauges) typically have maximum allowable Cylinder Head Temperatures of around 350-375f (about 175-185c) which is well above the boiling temperature of water. Install a 10mm flat aluminum washer between the spark Peak EGT occurs at approximately the stoichiometric (chemically correct) mixture of 14.7 pounds of air for each pound of fuel, at which there is exactly the right amount of oxygen to oxidize all the hydrocarbon chains in the fuel. VDO 600F Cylinder Head Temperature (CHT) Gauge, Cockpit, Black Face, 2 1/16", V310901. They must be fished from both directions with a thin line. them and could guess when maintenance is due, but then.
