John,
You and your shop have always been fair in helping me with any equipment issues, but i will disagree with you on this one. If i set my spring relief to 13, it probably starts opening at 11. If I set it to 16, it won't start leaking till 14. I do run a
glide and I would put money on it opening and sucking air through the relief prior to 13. Longer hose runs it matters even more. Any air that comes through that releif isnt coming down the hose...and I want my air coming down the hose.
Who said i don't have a degree? I dont necessarily beleive the engineers know more than me on every aspect. I had a 1994 Ford that required the radiator removed to change alternator....who engineered that bright idea. I also added a 12 gallon water box to my spitfire 4.0 so it wouldn't dump so much water, and it worked And it maintained 2-210 all day long after that, nearly a 10-20 increase. Guess what you see now on most HX truck mounts? Yah, large water boxes.
yes we run glides. Not sure we would ever go glide less again.
