Squeezing some more mpg from a brick
Hey all, I have a 1968 Jeep M715 that I’ve rebuilt with a modern powertrain and drivetrain that I use as my haul truck for work. It went from 7 mpg to 12 (mixed city/highway) after the swap. I’m now building a 45 degree windshield frame (I’m an aluminum fabricator) and I’m wondering how significant the difference will be. The current window is a vertical 5’x2’ flat surface because they were never meant to go faster than 45 mph. Main goal is to make it a little more economical to drive I’d be pretty happy if I could get to at least 15 mpg and the windshield mod is pretty far along already so it’s happening in the next couple weeks I just find my curiosity getting the best of me as I build it. Not sure how this post will be received as I’m sure it’s fairly different than what usually comes on here but I just figure “what better place to ask?”. Eventually I’ll also build an aero cover over the bed.
