Hi, I have a 1992 International dt466..Its a transit style front motor school bus.
Its turbo, so I believe the HP is 210? (not positive on this) The tranny is a allison MT643. The rear end gear is a 444.
Problem, it pins out at 3000 rpm(governed) it runs 65mph and can't hold it there that solid. What I'd like to do is change out the diff to a either 391, or maybe 373?
Then turn up the pumps/turbos to give it a little more HP and torque. This way I'd be able to run lower RPM at 65 or even run at 70 and still have a little peddle left for passing.
Ideally I should be able to run 70 at like 2300 RPM? right in the height of the torque peak.. (this is a guess, hard to find a chart
What do you all master diesel guys think? Would this be the way you'd go? How hard is it to squeeze some extra power out of this guy?
What do I need to do. Anyone reccomend a shop near raleigh or Charleston SC?
The bus has 190,000 miles on it. We're turning it in to a nascar bus.. 6 bunks, shower, crapper, 15000 btu ac unit on top, 7550w Generac generator on the extended bumper, 12,000# hitch with 3 foot extender (8000# usefullness, not that we'd ever tow much with it, maybe a few motorcycles) The trim work in the inside isnt' finished, waiting for the electrician buddy to wire the 110 boxes
Would be greatfull for anyhelp you could provide!... THANKS!!!
