I broke in a new C6 L2G on a break in bench. The bench version I have, employs a prop to act as a load for the motor during it running in. On the older versions of the C6, all I had to do was place a piece of paper board around the heatsink to prevent the coolong from the air from the spinning prop.
With the L2G on the other hand, I had a hard time keeping the temperatures I needed, even with the heatsink wrapped. I had to run the motor without the heatsink to maintain the 200-200F I needed.
I must say the new L2G head must do a very good job in cooling, on the other hand I wonder what the operating tempatures will be once mounted in a car. I would hate to se the temps drop to low.

The L2G cooling-heads are beside their lower gravity also a little better cooling, however we are not sure how you are measuring your temperatures or if it is simply extremely cold outside where you are...
We found that because the L2G cooling-head is lower you also measure closer to the glowplug and this might give you a hotter measure then before if you do this with a infrared temp. gauge. This we veryfied and we found also higher temperatures but the engine itself was not hotter.
In any case we did not find very big differences in the working temperatures of the engine but I cannot judge for what has happened here, I suggest you keep us informed about your further findings but also calibrate the device you are measuring with before jumping to any conclusions.
