So this summer I asked Texas Track Works to make ducting after my engine coolant temps were hitting up to 233F in July. We tested a partial solution in August (just from bumper to radiator) and that was a promising 5-7 degree drop across all laps, and finalized the design and flushed the coolant before this event. Air temps were about the same as July, with more humidity this time, and it looks like I've got at least a 12 degree coolant temp drop without cutting the hood.
