My '93 Dodge 250 4x4 w/Cummins was dyno'ed at just over 800 ft-lbs at the wheels in 4th gear direct with 3.07 rears. It was still going up, but I smoked and blew one of the rear tires because slippage on the metal roller overheated it. The Cummins shop said the 3.07 gears meant that it would be putting out over 900 on a chassis dyno, but I don't know about the accuracy of that.
After I cooked the Getrag (which even the Dodge mechanics called a "Got-a-rag") towing my tractor around (with the L4310 and implements on the 3-axle trailer, I was routinely grossing 25k), I retro-fitted the NV-5600 6-speed into it. So far, so good, with that tranny, but I've redone the injectors, and upped the turbo boost from 20 to 30 psi since the dyno tests, so I don't know what it's putting out now. (From what it did to the Centerforce Competition clutch that was rated at 1000 ft-lbs, a Sachs guy said it's got to be putting out at least 1000, but again, that's not verified.)
Right now, I've got a carbon fiber clutch in it with a 40% stiffer pressure plate that's holding well, but the truck is down again at the moment with a bad slave cylinder. When we did the tranny retrofit, I made my own hose in order to mate a new-style slave cylinder to an old-style master cylinder, but didn't think about the fact that brake fluid would eat up the rubber lining of the standard hydraulic hose, which contaminated the seal in the slave cylinder and ruined it. So I have to have a hose shop make up a special hose with a teflon liner. They couldn't find the right fitting, but I've finally got all the parts, just have to put them in. Never a dull minute - when you play, you pay... /w3tcompact/icons/smile.gif
