================
> Today was the 1st opportunity for a test, of 180 km. I will have fuel consumption numbers tomorrow (fill-up #2 with mods).
> I monitored the engine water and intake manifold temps carefully during the trip, and I suspect I was a bit overzealous in the degree of grill-block. With an average ambient OA-trip temperature of 0 DegC, the engine water stayed cool enough, but the IA temp rose to +30 DegC, which is a bit warm. When I ran the interior heater, the IA temp would drop ~5DegC
For tomorrow's trip, I'll cut 2 ea 1" x 6" slots in the centre of the grill for additional cooling, and when it gets cold (ie -20 DegC), I can just tape over the slots.
