I was curious if they made plug/play boxes for Semis. Wonder what the torque #'s would be on something like that?

Can't count that high, but just think about 500 plus cubic inches and twin turbos.

A torch, a few days off, some creativity and we could get one in a CRD.

Grab the Sept issue of Diesel Power Magazine. They have a 4 page chart of truck engines made or sold in the US.

Example:Detroit 12V-4000 48Liter V-12 1120HP 5615Lb/Ft torque. I think that last 15 Lb/Ft is just marketing hype though. It does weigh 13,000 lbs so it going to take more than a weekend to shoehorn it into the CRD.

5 or so years ago Cummins brought out there new signature 600 engine. It had 600hp and something like 1200lbs torque. I remember reading an article that they toured the country in it with instructions not to let another semi pass them. It had a tuner of some kind in it because with the flip of a switch the engine output would double to 1200hp to prevent anyone passing them in the mountains! That's a tuner! You can change many heavy diesel engine hp and torque ratings just by buying the manufacturer's program. You can have the same engine and have numerous different ratings. It's quite common. The cost is usually around $100 per hp gained. Does anyone know if VM makes a marine version of this engine?

At Freightliner, we program each engine before it goes into the truck. HP and torque curves and other settings are tailored to what the customer wants and to best match the running gear on the truck, ie tranny and axle ratios, type of service profile, etc.

The engine nameplate will usually list the max that the engine is capable of, and then we'll have a different set of numbers on our paperwork as to what to program the ECM with.

Mitchell is right. The class 8 trucks can be programmed to what the owner wants, to the limits of the engine. Programming can be changed at will. We changed our Cummins ISX's and N14's all the time to reflect what we want.

I just wish there was a practical way to do this to the CRD. Lot of changes can be programmed into the commercial engines. So much so that it will boggle the mind. Most of the options are just bypassed when on the machine.

This is likely just as easy on the CRD as any big truck. When I first looked at this engine in the late 90's it was at Detroit Diesel's R&D facility. They were controlling it with what appeared to be off-the-shelf DDEC IV software.
