Today I went to town for the first time in a couple weeks to fuel up (diesel is at $2.25 now). This is the first time in the last two weeks the truck wasn’t dragging my dump trailer around, so this is the first test of how well my new cowl induction air intake works under normal circumstances. It’s actually really interesting how it affects the temps and boost at 55mph in fifth gear. Just cruising on the highway my egt is down to 400* with 2.5-3 pounds of boost. The real interesting thing is that a few times there were some wind gusts and I saw the boost jump to 4psi in the wind and then drop back to 2.5-3 psi when the wind gust passed. Also, before the cowl setup I only got around 1 psi just cruising. So it appears the cowl induction creates about 1.5-3 psi under “normal” circumstances
