Leave the old CHT in and add the JPI. ring, and cylinder will experience much greater wear. 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. The head temperature gauge, which is commonly found on air-cooled engines, displays the work that the engine is doing more quickly than an oil or water temperature gauge.

This causes ppto occur later and CHT to decrease. Having an engine monitor that displays and records CHT and EGT for each cylinder is also absolutely invaluable for detecting and diagnosing a wide variety of engine problems. Sounds like it's running lean. Replace the old CHT with an STC'd item and write it up on a 337. Either richening or leaning the mixture from that point decreases the burn rate, causes ppto occur later, and consequently reduces CHT. Air-cooled engines rely on natural air to keep the engine cool.
