1978 heater box - Heat Dump Tubes with pictures.

Maybe by aiming the dump tubes out the back it creates enough thrust to increase the vehicle speed by .017% on a 6% grade.

[quote="aeromech"]Here's some on a 1978 bus I flipped a few years ago

Didnt think much about this since Crusher is a 77 and has the domed head type. But after seeing Colins old post about cutting the head off and retro fitting some flex tubing to it, am gonna do that. This bus will be running around the Sierras and Moab area next summer. I forsee boiling fuel or pump failure without it.
