While micro was curing I went ahead and fired up the leaf blower to test flow on my oil cooler. I was going to use 36 small string tufts to test it but after firing up the blower found that air was coming through the cooler rowes really well. The really surprising thing was the pressure increase. The air coming out of the blower was slowed WAY down by the time it exited the cooler which is great news for absorbing those BTU's. I did notive, though, that the air was notably escaping around the base of the cooler which means an RTV or weather stripping seal will be a must. Fun stuff :)
