Have you calibrated your instruments with somethin= g reliable like a good mercury thermometer?

Normally CHT has a much shorter time const= ant than oil temp. If CHT levels off in the green you probably have enough = air flow.

Possibly problem with vern a therm or hose routing not flow= ing oil through coolers. You really need temporary instrumentation to measu= re 4 temperatures, inlet and outlet oil and air temperatures to the oil coo= lers. That data will point you in the right direction.

Hello All

I am having unbelievable trouble cooling my engine.=

I have installed two oil coolers, got the Zavatso= n plenum on, yet l can't complete a circuit without the oil temp hitting re= d! I am cutting out the intakes to make them larger now and opening up the = outlet too.

l have a Mccauley prop on the aircraft= , would this make a difference compared to the Hartzell?

Thanks
