I just wanted to share my outing with my fellow Speedster owners. Yesterday I drove up Interstate 17 to Prescott and then came back home via 89 which is quite a scenic drive with lots of switchbacks and windy curves. It's still running well over a hundred degrees here in Phoenix but much cooler in Prescott. It stayed cool for much of the drive home but got pretty hot for the last 60 miles or so. I drove mostly around 70 mph, except for the mountain curves. I pushed it up to 90 briefly as I came down off the mountain and there was a long straight away.
I stopped at the Granite Mountain Hotshot memorial which was located along 89. Also, my car didn't go over 210 degrees and got 29.9 mpg. Before you ask, it's a little 1914 with ICTs. I'm pulling parts together for a nice big engine.
