The new heads with the new valve seats don't do this so you can drive safely at Freeway speeds and at 400F CHT's. Still constant 450F CHT is scary as at aluminum heads can suffer from that prolonged heat. While tightening the spark plug, hold the sensor so it does not touch any parts of the air duct (if there is one) or the cylinder at any point. We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. If all you have is the factory CHT gauge, then all you know is the CHT of one cylinder (and only very approximately at that) you have no idea how hot the other five are running. Retarded ignition timing that ignites the air-fuel charger later and causes ppto occur later increases EGT. Email care allows us to provide important service detail that can be later referenced by both the customer and our care staff. Run whatever oil you like, but I'd run SAE 30 and check intake / cooling fins regularly I thought about putting exhaust wrap on it this morning.

The "missing gauge" on an air-cooled vehicle. which varies widely from manufacturer to manufacturer. There are cylinder head temp and oii temp gauges made for air-cooled VWs that would work. As things heat up even more, the piston will seize and the engine will stop. EGT is affected by mixture. 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. than normal running engine is fouling of the piston rings and lands. It requires drilling a hole in the exhaust manifold right at the
CLT / CHT temperature is only really used for warm up and fan reference isn't it? The wasted energy is measured and displayed on a triad of cockpit gauges: oil tempera-ture, cylinder head temperature, and exhaust gas temperature. 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. About half the fuels energy goes out the exhaust pipe, while the remaining one-sixth is transferred to the cooling air that passes over the cylinder fins and through the oil cooler. Bottom line: a cool running engine will last longer and have fewer problems. I just tested a high rpm piston port intake 55cc Grubee engine and I redlined it for a mile at 9100 rpm and it only got up to 425 degrees farenheit. cut in the duct by the spark plug 3/8" long and a width of the space between the fins, as shown in the photo. Of course, if pilots have lots of money and

of how your engine operates in various conditions, which is important! The cylinder head temperature is just as relevant for air-cooled VW or Porsche engines as the oil temperature, especially with modified engines you should keep an eye on it. Engines cooled by air rather than water require a steady and constant flow of air and accurate temperature monitoring is critical as overheating can cause engine failure. Richer mixtures also cause EGT to decrease because excess (unoxidized) fuel absorbs heat energy when it vaporizes. My question: Does anyone know the best / optimum CHT to operate a Lycoming IO-360A1B6 Angle Valve 200HP + with 10:5:1 compression. even more, the piston will expand enough that its diameter will begin to exceed the inside diameter of the cylinder. Northeast - Middletown, PA
