Turbocharge a 4100

Can you turbocharge a 4100 and what are the benifits. Cost.

I don't know about the 4100, but I have a new Garrett turbo # TA3101 that will be installed on my 4700 this summer. It is sized for my engine's displacement, RPM, and boost level I want to run. I picked it up from e-bay for quite a steal and it is just sitting here in my office.

Do I need it, No, but it will be an interesting project to work on. My buddy (master diesel tech) and I will design and build the exhaust manifold adapter, new inlet manifold, and oil lines here at my machine shop. I am hoping for and additional 10-15 HP at 8-10 PSI of boost. The injector pump will need to be advanced to deliver more fuel for the additional air.

Check out this website for some great turbo info (it's Australian, but great info): http://www.turbofast.com.au/custom.html

Thanks for the info, just considering options.

Some people enjoy a challenge such as installing a turbo or supercharger on their car/truck/tractor etc.
While I could be wrong it is unlikely much benefit would be derived from increasing the power by turbocharging a lightweight tractor like the 4100 (similar Kubotas etc also). It is unlikely the internals of the unit would be up to the task of the additional horsepower, a larger radiator or fan etc might be needed to reject the additional heat or an oil cooler to help out. Essentially if you need more power you need a bigger tractor. Not only that but there is such a thing as turbo lag, by going with a small turbo and setting the waste gate such that it is kept spooled up lag can be minimized. Soooo, you set the throttle at say 2400 RPM and as you move into the pile of dirt with your FEL the engine begins to lug but then the turbo begins to build boost and the tractor lurches forward and the wheels loose traction and the load on the engine is thus reduced so then the turbo spools out and then the wheels grab hold again loading the engine and the turbo spools back in etc--this is called bootstrapping effect--one thing effects another thing in a sequence. Just get a bigger tractor and leave the experimenting to those who enjoy such things and occasionally have the talent or expertize to make them work.

Boy great advice and I thank you for your info. Just looking into options, and I agree that the cost is not worth the benifits.

Also - Remember that although the turbo might force more intake air into the combustion chamber, your fuel pump regulates the amount of fuel and the rpm... These two factors impact HP more than intake air volume... especially on a diesel engine. On a gas engine (with a carb), if you force more air through it, it will take more fuel with it (and make power)... not so on an injected diesel engine.

Yes... you could play with the pump settings... but let's not go there right now...

I have been playing with diesel engines for a while now including my 97 F350 with 450 RWHP diesel. Propane injection is another way of increasing power. I also have that on my F350.

I do enjoy the challenge and look forward to this "new" project this summer. I will post all my findings and a final analysis after I install the turbo and get everything working properley. Like I said I really don't need the extra power, I just like tinkering.
