Tonight I finished the lower grille block.
It takes approximately 25 minutes WITHOUT a lower grille block and 85+ degrees F external temperature, to reach 200 degrees F water temp- and it won't go past 203.
After completion, I took it for a test drive.
I did not do ABA testing. I found at 61 degrees F, it took approximately 16 minutes to reach 200, and by 25 minutes was at 214. I also found the fuel economy was better than ever before with the engine on. I am not sure how much aero has helped, although I noticed my normal coast points forced me to use te brakes (usually I end up at the speed I need for lower speed zones- today I had to brake and slow down to not be speeding). I am more so thinking the increase in FE is because of a warmer engine bay.
It SEEMED that I was getting better fuel economy, but to be clear, there is no real set data. The setup I put on isn't friendly to take on and off, so I doubt it will happen. My only concern is what the top temp I should let the car get to before removing portions of the grille block. Hopefully, I can just remove the little side pieces to maintain a temperature-if I am forced to. I would rather not have to adapt it at all.
