OK, summer is here at last! Means I can start lying on the ground again!
So, things that have happened since the last post: I have been running the tires at 40psi and have kept my upper grille block in place. Initial results seem to indicate that both have helped, and I am now hovering around 29MPG, even with some occasional towing in there.
However, temperatures are increasing, and the upper grille block may have to come out for Summer - will keep an eye on the temps.
The biggest news is that I found some Coruplast in a "free firewood" bin, and have made a front air-dam. No FE results yet, but initial impressions are that it looks tough, and strangely makes the engine seem quieter.
My guess is with less wind traveling under the car, it's just quieter in general? Weird.
Anyway, here are some pics.
