not to steal the ops thread but I'm in the same boat. I ran mine this weekend and could never get any heat out of the charger. It started to pop and crack at about 200' mark. when I was done with the run used a temp gun and shot the water draining out of the box and it was 50* or so. What is the temp of the water after a run most of you are seeing? I either want to use less ice or take fuel out of it to get some heat built up. I used 110# of ice. I don't have a intake temp gauge yet but will get one. I have a video but it is of poor quality.
