LBZ Operating Temp

[petestoy]

What is the normal operating temp of the LBZ? Mine seems to sit at 175 when cruisning on the highway 60-70mph or driving around town. if i do 70+ it seems to climb up to 210? the winter fronts are on and outside temp has been around -10 to -20C.

that is normal, though 200 is a better temp for efficiency. I have used a little extra ECT boost to make a warmer motor bay, and warmer combustion air to warm up faster.

The radiation losses become the primary heat loss in the cold weather.
