CK 35HST - more power?

That is correct and was not how it was written...reread

Has anyone tweaked their tractor to get a bit more power. (turbo, blower, better air flow, tweaked the pump) Just wondering what might be done. I am not looking to enter a tractor pull, just to overcome the bogging in high range when going over a few hills in transport mode.

Thanks

PS I also am running at over 6500 ft in elevation, so I am basically looking to just overcome this elevation difference to get that lost power back.

There have been a few threads on TBN where people added a turbo to their diesel tractor. the threads I read were successful in the turbo addition

and the owners seemed happy with the results...


Some differences in gas and diesel engines i am aware of

Since diesel engines are compression engines
air /fuel ratios can be much wider than gas engines-
there is no throttle blade to limit air intake on most pre 2012 diesels other than ( Cummins 6.7s maybe others) unlike gasoline powered engines
and they do not suffer from detonation like all gas engines- excluding the new direct injected ones which do not suffer from pre-ignition or detonation ..

Direct injected diesels (supposedly) lend themselves to turbo charging compared to Indirect injected diesels due to having lower initial compression to begin with.

Maybe one of the guys who has successfully added a turbo to their diesel tractor will chime in.

Don't think that a Kioti has been user turboed yet

Was looking into this for my Bobcat CT 235 - twin to yours. So far no turbo dealer will help, and now I am looking into small belt driven blowers, Probably wont do anything, but fun for an old engineer to think about it.

BTW have you had your dealer tweak the bypass pressure on the hyd. Mine was upped 200 lb and made a big difference.

There is the same amount of air but the molecules are more separated
so you need to decrease the amount of fuel, or lean it out, for proper fuel burn. This increases temperature
as said and in aircraft you monitor EGT (exhaust Gas temp.) or CHT (cylinder head temp) to keep in proper
operating temperatures.

AND, the pilot can actually control the fuel/air mixture from the cockpit...something you don't see in cars,
trucks, or tractors.

Turbos are ideally suited to airplanes, for reasons you stated.

With respect to turbocharging diesel tractors, you should be able to increase fuel by increasing the fuel
injection pump pressure. You can optimize for a particular RPM, something you can't really do in a
car or truck. I have not done this on a diesel, but I did have to play around with injection pressure
on a custom turbo installation on a mechanically FI-ed car (K-Jetronic).
