We used to do 1 desert race in the dead of winter in Barstow. Yes boys and girls, Barstow gets plenty cold in winter. Since our motors were stockers we had to use what VW made for them as far as manifolds and carbs go. The stock manifold had a built in heat riser to keep the plenum from icing up. Some racers cut the heat risers off to save a couple pounds. One of my creative competitors mounted a small driving light to the manifold pointed at the plenum to keep it warm when necessary :rofl:It worked. I guess he didn't want to swap manifolds for that winter race. :steering:
