What is the ceiling height of your bus?

[Johnny Mullet]

Originally it was 6'2" but is now 6'1" due to flooring.

I got a few of my orders in the mail and will make an update soon. These are basically items to add the finishing touches to the bus. The bus is nowhere near 100% done, but getting there.

Doesn't that sound familiar! I've taken to answering the "how close are you to done?" question with: "90-ish-something percent, give or take....there's still some little things"

More goodies from Amazon. I also had to winterize my water system..........

I took the bus to the shop to do a front brake pad replacement and a muffler delete..........

someone told me the muffler on a 444E is very restrictive. im interested to know how it does without.. also just has to sound better! are you runningthe outlet still out the bumper or off to the right side in front of the rear wheel?


on a side note I turned mine up to 230 HP this weekend.. if you program in the right EFRC code (navistar publishes them).. it lets you do it.. and it works.. now im in the territory of needing a pyro before I play with anything much above 210.. apprarently in some years they had 230s with the smaller turbo. being that our turbos are limited by the small inlet size.. (no wastegate).. the bigger turbo has a bigger inlet and is waste-gated..



while I may not have 230 i can tell i def dont have 190.. I stay in 6th gear far more now than i did previously on the highway..

I ran the exhaust bypass right to the original pipe to go all the way out the back of the bus. I don't hear any difference in sound when driving the bus, but totally hear the difference at idle standing behind the bus. I can actually hear the turbo! I assume it's a tad louder out the back, but I can't hear it driving it.

On the drive home I noticed the difference in power right away. The bus accelerates faster and takes the hills at a better speed. On hill I hit on the way home the bus always downshifted near the top, but today it did not downshift.

I would love to hook up with you sometime for a ECU tweak. A bump in HP would probably make this bus perfect for all driving conditions. I did find out I have a 4.78 rear end ratio from the dealer today.

that rocks!!! I def need to make that exhausrt mod! I want to hear my turbo!.. I can hear the turbo on my DT-360 and it sounds cool.

Hmmmmmm - I wonder how restrictive my muffler is, and would it be beneficial to remove it? Would the noise be too much?

Thoughts?

Thanks!

Wow! It was one year ago today that I brought this bus home and started the conversion.
