Went back and read it again. The 3/4" X 1/2" bushings are restricting the airflow. The first build I did I used them for a cleaner close look. Had to have 4 to get temps. Since went to 3/4" nipples with caps and it seems to be just about perfect.
Yup, had to reread this myself. Not enough intake here. Replace with pipe nipples and you should see a big difference.:wink:
