Has anyone done the I-40 West trip from the burlington SC? I'm curious as to how far you can realistically go. The grade going up Old Fort Mountain is quite steep, so I'm wondering what the real world impact is to the range. In theory there should be a West Asheville area supercharger installed some time this year - but until then I'm trying to figure out how close I'm cutting it if I try to get from the Burlington SC out to the Canton/Waynesville area....
