I drove a moving truck that was empty on I-10 and the truck had the International T444E. You talk about an engine with no guts or balls. The piece of junk would not go any faster than 65, my foot was on the floor. The DT466 isn't much better either. YOU DON'T WANT AN INTERNATIONAL ENGINE, they are the Yugo of diesel engines. Pure junk.

That engine may have had a governor on it, typical if it was from a trucking company or a truck rental company. Also the T444E is available with at least three different turbochargers. Also depends on your transmission and differential gear ratios.

If the air filter is dirty it won't go very well either. Did you check to see if it had a governor on the engine? Which turbocharger were you running or was it a naturally aspirated diesel? Did you check the air filter?

[jmkpns]

No governor on it, engine oil is at safe level everyday and air filter is okay,, but I drove a Freightliner flatbed truck with a M Benz straight six and that engine was mighty fine compared to any of the two Internationals.

[cdemon2002]

The T444E is 7.3 litres 175-210 Hp depending on turbo and engine control configuration.

The Freightliner flatbed you were driving may have had the MBE4000 6-cyl diesel with a 12.8-liter displacement and 350 to 400 hp.

Could 5.5 litres be the difference you felt?

ehhhhhhh the 24v cummins sounds better!

[cdemon2002]

Thanks, I'll look for it on Youtube.

Unless you are some kind of diesel engineer you will not likely know what parameters the mfr. has set into the design as far as Governor settings are concerned. Labeling an engine as a "piece of junk" is shows how ignorant you are.

@jmkpns Define "get up and go." I drive a Detroit 60 everyday at work, mated to an Allison 4000, in a chassis that only weighs 36,000. Sure it has GU&G, but look at how much that drivetrain costs, and the power/weight ratio!!!

I've driven plenty of Int. trucks with get up and go. It's all about torque/weight ratio, and the gears you're using.

BTW, my daily driver has a International in it too (Ford Power Stroke), and it has lots of this so called "get up and go."

[jmkpns]

@txgp17 You make a valid point about the transmission, but point is, any International truck I have driven old and new did not have any get up and go whatsoever.

[txgp17]

@jmkpns You're criticism is useless if you're not also telling us what kind of transmission, axle ratio, and tires you were running.

I used to drive a truck with a T444E in it that wouldn't go over 65 either. The problem wasn't the engine, it was the transmission. The buyer got the cheapest transmission they could, an Allison AT545, and it didn't have an overdrive.

I saw a similar truck with a T444E with an overdrive transmission, completely different driving characteristics.

@cdemon2002 our freightliner's 12.8 has 450hp, most are rated at 450

@mr3vil666 just different paramiters built into the engine throughout the years because of emmisions laws so they had to run hotter then the school busses

[ps3dethman1]

my school bus has the same engine. its a 95 and it's never bin in for repairs says the driver...and its wont go over 65 cause it has a speed governor...now there was this new bus 3 yrs ago that broke down on the first day (locked up)... it had a cummis...thats the only cummis ive ever seen blow up.

@cdemon2002 I beleive the governor would be in the pcm, so not visible

[jmkpns]

@mr3vil666 I drove a GMC Duramax with Allison transmission and it drove like a dream. Nice riding and nice driving.

@amfan12 The Powerstroke is just a re-badged T444E. They are made by the same company. A label on the pass side rocker arm cover of my 7.3L Powerstroke even has International's logo on it.
