MFR Bus No. 637
 
Hey there! First of all I would like to clarify that MFR stands for Moore Family Racing (I am sure some people would assume something different) and number 637 is our racing number(came up with it by dialing MFR on a phone). So I have been lurking around on here for a month or so taking in a lot of your ideas that I could use on my own skoolie. We were looking for an RV to sleep at least 6 for race weekends. We quickly realized that they weren't affordable which led us to the bus conversion.

We purchased our bus today. A 1998 International RE with a T444 Diesel engine. We picked it up 400 miles from where we live in KY. Everything ran great on the trip back. Although I have two questions. How do you turn the governor up? The bus topped out at 62MPH at about 2200 RPM's. Second question is I kept hearing a buzzing noise coming from behind the panel where all of the switches are. It sounded like the buzzer you would hear if your air pressure wasn't built up. This was not the case. All of the guages were good. Where could that noise be coming from? Thanks for any input!

Need more info. What's the engine revving up to in lower gears? Reaching 2500+ RPM before shifting? Or maxing out at 2200 in all gears?

If it's revving higher in lower gears, then you likely have a computer based top speed governor which will need to be changed in the engine computer.

Also need a little more info. Any warning lights?

Fellow International RE/ T444e owner here!

Welcome to the forum, lots of helpful people on here! Have already helped me out a ton already!

Lets see some pics of the new bus!:biggrin:

I would agree you have a top speed limiter in the computer. On shifts that engine should be going up to 2600-2700 RPM's. Which should get you up an additional 5-10 MPH. Be aware you will be sucking down a whole lot more fuel going that fast.

In regards to the buzzing, if it sounds like a warning buzzer I would check the roof hatches to make sure they are latched properly. Since they are plastic they tend to not want to reseat properly when they have been opened to check the emergency exit buzzer. It could also be one of the side or rear emergency exits/windows with a switch that isn't closed all the way with the exit/window closed but not as likely as the roof hatches.

Most of the T-444E's I have found are limited to 60-62.. some at 55...

my own Opinion is that T-444E's in that half-ass international radiator setup like to run hot... and iot can be the schools also..

I had to remove the speed limiter on my T-444E via the computer interface.. mine was running at the same.. 2200 at 62 or so..

Welcome! Another race hauler here. My short bus with a 7.3 (same engine) turns 2500rpm at 65 mph. Just slowing down 75 to 100 rpm (62-63mph) makes a noticable difference in MPG.

Once you removed it, what speed were you able to run and at what RPM's?

I can't get the pictures to upload for some reason....

the factory has a safe rev limiter at 2700 on my version of the T-444E.. I run self-imposed rev limiter of 2600.. (everything you read says even 100-200 rpm can add longevity to the engine..

how fast you can go all depends on your rear gears, tires, and transmission..

my particular bus will max out at 70 or just above... like 72 when i hit my 2600 RPM...

some schools disabled the cruise control.. this can be re-enabled in the computer.. with a T-444E cruise control is built into the computer regardless of whether you have the dash-switches for it or not.. its really easy to put it on if your bus doesnt have it.. and the cruise doubles as a fully selectable RPM idle speed control..

from the sounds of yours im guessing youll be able to reach close to that 70 MPH mark judging from your RPM when you hit that limited speed...

I drive mine at 65 as it runs really nice there.. my MPG didnt drop much from my 1000 mile maiden voiyge at 62 (before I had the computer program).. and the 65 that i drove it the next 1000 miles..

I'll make a run in it at like 58 next when I bring it back to florida to see how it drives.

the T-444E likes to get Hot on Hot days when you run its RPM up... esp if your fan clutch is weak or doesnt engage soon enough... Heat is very bad for these.. 230 and bad stuff happens or can happen esp if you are running it under load..

I also programmed a couple of Alarms to yell at me.. if I reach 220 degrees coolant temp.. I dont think it has an alarm for oil temp but 250 oil temp is pretty high ... I set an oil pressure alarm as well..

if not otherwise specified, all internationals leave the factory with a 62 MPH top speed set, I used to deliver new ones
