International DT466

[sevenpointthree]

i'm not sure if you can for that model my uncle had a big international dump truck that he unplugged the map sensor on it cause it was a terd till 1800 rpms when the turbo kicked in now it kicks in any rpm when you hit the gas. this might help you.

Well the fastest this one will go is 60. I have it up to 85 down hill I just pushed the clutch in and let her roll. Its pretty scary. I guess the company I work for just has them governed. Even the 6.0 foreman's truck don't run worth a crap. You have to put it in low just to put out.

our DuraStars are governed to 68mph

They were 'turned back' by the dealership, I believe, and were electronically prevented from performing to their maximum potential.

I don't know how it is done, but they very quickly went from being able to easily do 73 to 75 mph to only being able to hit 68 mph downhill. There is something in the electronic engine management system where they can plug in a laptop via a port below the dashboard and reset the idle, top speed and power output.


That old DT466 is a good engine, though, and will run forever if properly maintained. We replaced our Internationals with new Sterlings and they're mostly junk. Even though they have good engines (Cummins ISB & ISC), all that smog stuff hinders their performance and fuel economy.

I sometimes drive a big rig - '04 International 9200i - with a Cummins ISM; and I am hoping the boss keeps it awhile longer so I don't have to drive a Sterling tractor. The Sterling tractors have the Mercedes-Benz engine (sweet), but I just don't care for the rest of the truck. Sterling ain't nothing but a "el cheapo" knock-off of a Freightliner.


Good luck with getting some more guts out of those Navistars!!

The Mercedes-Benz motors are pure junk. Pure junk.






There actually being discontinued as well. Thank god

The 2004 and up DT466's were never a real powerhouse. The turbo is a weak point on them, it is a very common problem for the VGT to not work correctly and hinder performance. There are a few quick and easy diagnostics you can do to see if the turbo is working correctly.
