I made it across the country. A few weeks ago. Goats and all. I managed to convince a friend to take a vacation and come for the drive. I have 15 gears, my turbo works awesome. I can pull sustained grades at appropriate highway speeds, many times even able to accelerate and pass up big rigs easily. My fuel economy in high elevation mountain regions with lots of big hills to climb is about 9.5 mpg. In Utah, Nebraska etc, I average about 12. I am able, if I choose to accelerate all the way to 90 mph. I can cruise 70 mph. When I am in double overdrive I cruise 70 at about 2200 rpm. I occasionally rev all the way to 3000 rpm. With no ill effect. My exhaust gas temperatures and coolant temperature never entered any dangerous range even while climbing the Rockies on a hot hot day loaded down with 2k pounds of cargo. A hail storm in Nebraska ( no kidding ) took out my radiator, so I spent the night on the side of the road waiting for a new one. So now I installed a gold screen to protect the new one, very stylish haha. The goats loved the trip. They rode inside. I decided to forego the up top concept for the time being. I have yet to adjust my IP. Even so with it at stock setting, I build about 7-8 psi at2600 rpm, with stable egts of 1000 degrees on a hard pull. By adjusting my ip I should be able to safely achieve about 10-11 psi peak boost without raising my egts or over stressing anything.

So here are the bullet points.

Yes you can turbo a 6.9
Manual transmissions are more fun.
Two transmissions are even more fun
Never tell Me what I can't do
I'm getting 200 some hp with 12mpg in 13.5k lbs bus
My goats loved the trip
My dog loved the trip
My bus goes faster than yours. ;)


Ps. I just took a trip to the coast in her and let me tell you, she carved highway 140 like a pickup truck.

Good work on getting that Brownie linked up! Question: How loud is it? I've heard that they can have quite a whine to them. If I could get my hands on one for cheap I'd probably give it a go. It'd be nice behind my 5-speed Spicer.

The brownie box is awesome. It does have a whine to it. It's most pronounced in certain gears at certain rpms. It seems like a harmonic resonance sort of things. I could probably adjust its mounts or build a box around it to help quiet it down but it doesn't really bother me, but then again, I also drive a first gen cummins with a straight pipe exhaust. I might look for a 4 spd brownie if I were you, then you would have 20 gears! I am actually serious considering swapping in a close ratio 2spd rear end for even more gear splitting action. I am about to embark on the journey of reflooring my bus. I will be laying down thick rubber sound insulating mat as my first layer, so we will see how bad the brownie whine is then. Ildifferent eras of brownies are made different too. Mine is from the 50s so it probably has more of a whine then one from the 70s

Plan on being a few hundred in for driveshafts, not to mention shift linkage. Try to find one you can pull of an old truck yourself. It will have the mounts and linkage etc. any questions about it feel free to ask I'm pretty well versed in them at this point haha
