Future of Glider Kits

!4 liter Detroits were available before EGR as was the ISX Cummins. The 14 liter Detroit was available in 3 power ratings of 525 horsepower, 550 horsepower, and in Freightliner only, a 575 horsepower version starting in the 1998 model year, I believe, until sometime in the early 2000s.

EGR dropped the available horsepower, but even before that, the high powered 14 liter engines were not in favor because of cooling issues. There are some botttlenecks in the cooling system from what dealers of competitive makes have told me. These were internal. Most 14s were set at 500 or less after EGR became a part of the system.

I don't know just when the 12.7 was no longer available, but were still listed in 2006 in sales literature with 455 horsepower as the top rating again, this is as best as I can recall. They may have been available after that, I saw some newer Foodliner midroofs sitting used with 12.7s that were at least that new.

The MBE 4000 had up to 450 horsepower in a lighter and cheaper to build engine. They also sound like an old school engine with the spooling turbo whine when the engine came on power, compared to a slight rattle from the Detroits.

II'm running a 2008 with14 liter @ 455 and it gets warm on a hard pull, but doesn't show signs of overheating. After one trip to a technician for a forced regen, the DPF has been working fine, regenerating mostly while driving. Some of the other trucks from the same batch have had more problems, but mine is running well enough to keep me satisfied, if not real happy.
