Not the greatest picture I have but...
There are down sides, when it rains my belt squeals as if a cat crawled under the hood, gets dirty quicker, people who see think it's cool but they are driving riced out hondas and they don't really have any cooling effect at speed.
Sure the heat is pumping out when parked and that might be good for longevity of items under there but in cold weather my motor (7.3) takes longer to reach operating temps.
