After looking closely at one of my 95*F test run logs, I think I have max out this combination as far as freeway FE is concern? Around 45 mpg with the waste solvent disable has been my personal best. I was considering making a belly pan and a full grill block but now I think I'm going to call it good.
All my attention is going to be on my waste solvent system. I'm running a 50/50 mix right now and its working great in this high heat were having. In fact I did some hill-billy testing and have my lawn mower running on a 60/40 waste solvent mix at 95*F.
My next project is to build a 1 liter lean burn 13g turbo 91 Talon FWD manual 5 speed transmission. This car will have all the stock interior, with all mods built for FE only. My goal is to get around 65+ mpg.
