Thanks everybody. You all went the direction I was thinking too, underneath.
My bus isn't actually that low... no, really it isn't
compared to some of the slammers I've seen, so I've got good clearance under there. Is the air any good? I can screen against debris and don't plan to do any wet weather driving so I think it is do-able.
I will work up some ducting ideas this week and see what fits... stay tuned
.
EDIT:
Some things I forgot to add,
I'm running a pair of the largest fans I can fit, they do their job, it will idle at 180 degrees all day, there's just not enough fresh air coming in at speed.
The rad I'm using is four times the size that comes with an Ecotec, when you have enough air flowing, it runs 160-170 degrees even on a hot day.
They make duct fans for the NACAs but they're not worth it, they pull over 3 amps each and only put out 140 cfm...
I do have the windshield vent but it doesn't work/is blocked with the safaris open and that's how I ride 99% of the time...
