Tonight I made a grill block for the Prius. With the colder weather, its really starting to idle a lot more, especially when traveling at low speeds where the engine is off for a prolonged amount of time. Hopefully this will speed up warm up and help with aero on the highway. Unfortunately, I have no way of measuring any benefits since the Prius was broken into last week. My
scangauge was stolen along with a few other items. Thankfully, the car was mostly intact (minus the passenger front window).
Anyway, pics!
Here are the fasteners I used. Thumb screws, fender washers and wing nuts. Its pretty much the same setup I used on the Matrix except I went with smaller screws. I think I used 1/4-20 on the Matrix. This time around I went down to a 10-24 thread and its still plenty big enough.
The block itself turned out okay. If you look, it gets sucked in a bit on the right side. Oh well, I'm not remaking it.
I'm still debating how I'll block the top grill. I'd like to go with coroplast, but since its a V shape, it'll be a bit more difficult making a block for it.
