Dear subscribers,

You might remember that I had a question about the cool air temperature into the cabin (see below).

I got a hint from Craig Berland to tighten down the jam nut that sets a pre load spring on the mixer box control shaft. I tightened it way down to fully compressing the spring.

It made a huge difference in the air temperature coming from the engine now – at altitude I run with heat now instead of AC. You might want the check this nut – you might be surprised!

Dear subscribers,

Since we are talking about cabin heat I got another question. What cabin temperature do you get from your turbos on the cool side (after the intercoolers and the additional heat exchanger in the front)?

I put my cool air supply hose in an additional fireproof jacket that has additional insulation inside (see picture) – the intension was to insulate against engine heat and get nice cool cabin air.

At higher power settings (32 MAP, TIT1620) the cool cabin air is about 100F. This means flying in the sun even in the high teens with OAT around 20F it still gets really warm in the cabin and I turn on the AC every now and then.

Is this normal? Any input is appreciated.

Ralf
