I log trans delivered torque which is around 85 ft lbs. not sure how acurate that is, buts handy in trans tuning lol

most your diesel generators run at 1800-1900.. so target 2000rpms and adjust your pulleys.. it will run forever at 2000rpms and with low load it should sip fuel.
Are you tuning this?

mines a 6.2 so may not be an apples to apples comparison but I looked up an old log and it looked like I was around 20ftlbs in park at idle and 65ftlbs in gear at idle, this is a calculated number the ecm uses but should be fairly close.

just found that each generator head needs 16hp to hit 3600 rpms, which puts out 7200 watts RMS. 160 hp gives me 72000 = sufficient.

Something to remember, all these #'s you guys are looking at are NO load. Load it up and the Torque will climb but you also have to have a way to open the throttle up so it doesnt kill it. Long story short, at idle and idle only you are not going to be able to load up those generators. When I say Idle I mean Idle RPM and Idle throttle position, now if you open the throttle up and load it up you could within reason power some stuff at idle RPM but throttle and fuel demand would not be idle.

No I dont tune. Probably should for this project, but dont have any software right now.

2000 rpms with the proper cam choice, I agree that the power necessary is attainable while sipping fuel.

thanks for the replies guys, helps me set target rpms, and adjust expectations. experimenting with the possibility of a total electric driveline in a custom chassis for commuting, while still retaining the ballistic nature of instant torque and all wheel drive. Power mostly coming from the generator heads, but supplemented with harvesting technologies (KERS and TERS). Right now its all about fuel usage vs max range. Aiming for ~50-60 MPGe. We shall see.
