L10 Cummins

I have a mechanical M11 - L10 mechanical hybrid. Get about 6.5 MPG loaded 50,000 gross one way. That is baby footing it. It can turn the sky black and pass slow cars on demand. Even the 11L can be really weak on the low end.

 

My low end maybe somewhat related to the transmission. Then the mechanical linkage is very touchy. It is an industrial engine, they can smoke.
Making swaps like that usually cost more than buying the truck you want. If you already have a doner truck that would be different. Since you are mechanical a Cat should be about as easy as an N14 with a doner.
If you just buy an engine and start buying what you need it will hundred dollar you to the poor house.

 

Maybe try adjusting your AFC to add fuel at a lower RPM. Drop your fuel button a size. Maybe two with a piro.

 

Maybe keep the stock turbo on if it has a wastegate, add the N14 turbo as the atmospheric turbo.

Should give a nice wide power band.

Just an idea. I like experimenting if I have the parts. Never seen anything done with a L10 though.

I am in the process of experimenting with 2 turbos for my 5.9 cummins. Just collecting the parts.
