My mechanic in Colombia said not to worry about it so I tried to live in denial ...without avail. Pilot paranoia wormed its way in. But I quailed at the thought of taking my instrument panel apart and wiring a probe into my dynon. So i bought a chinese rpm and CHT instrument from amazon and clamped the CHT ring to the aluminium up tube from turbo to airbox. The interwebs tells me that the max Airbox Temp is 88C T/O power 37" took the temps to 65C Cruise 29"-33" @3500' up to 5000' was steady at 56/57C. Intuitively this is consistent with the fact that I have numerous standard zip ties holding electric and control cables to the airbox and none of them have melted.

There are around 8 people planning to attend. Donuts and burgers/hot dogs are set. We're working on setting a hotel for those that need it. There is plenty of parking for planes and cars. I'll send gate codes to those driving in. Weather forecast as of today, looks nice, sunny with high of 74 low 54. Looking forward to seeing everyone.

The best sensor is one that is immersed within the compressor free stream. A 'K' thermistor would suffice. Thermocouples are more accurate and more expensive and are used on Rotax. The 914 HMM provides impedance reference graph for the plenum temperature sensor; you could possibly splice into this circuit for a piggyback reading, and you would need to ensure there is no risk of damaging the TCU by doing so. A comparable screw in thermocouple sensor itself costs about $8-$25 on ebay.
