CK 35HST - more power?

[powerscol]

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.

That is the HUGE problem with non turbo engines, altitude kills them.

Good luck.

My neighbor that plays with dirt track cars says he can set me up with an NOS system. I think that might be overkill. He also thought a small blower (just moves air) from one of the import cars (belt driven hang on unit like an alternator) might work, if a way to mount could be figured out...also around here finding one would be tough.

If you are going to fool with it at all, put a turbo on it. Like you said, you just want to get back to what you are suppose to have, which is plenty for that tractor. My Mahindra 3215 HST has a turbo and runs and operates great at 4100 feet. I know that is not 6500, but zero power loss. I think a lot of people neglect to pay attention to what altitude does to a naturally aspirated engine before they make a purchase.

My brother had been thinking about getting a Kioti CK35. He would have been operating it at elevations between 9000 and 12,000 feet there in Colorado, I talked him out of it, told him he really shouldn't get anything that didn't have a turbo on it.

Good luck with your endeavors. :thumbsup:

I guess I could go that way, but usually you need to reduce engine compression, and mess with timing, but I could adjust the waste gate to limit boost to say 5 or 10 lbs or so.

Now I have more time to search out some small turbo tractors to see if I can find a match. Does anyone know of any turbo tractors made by Daedong? At least that might get me in the ball park.

Or get a second BIGGER tractor ?????? Wonder what the Boss Unit would say. :confused2:

Banks Turbos use to do this all the time with 6.9 and 7.3 Navistar diesels. Kept the same everything, installed the turbo set for 8-9lbs boost and turned up the pump. My guess would be all you need is the turbo, you only want OEM power, not more. Of course the other alternative is to drop down to mid range, costs nothing other than time. You're retired, right???

Kioti makes some turbo tractors, but I think they're all at least 55HP. The DK55 up I believe is turbo, and I think the RX and some of the NXs are turbo as well.

I will say that HI is not meant to really have any load put on it, so bogging down going uphill is normal. I can understand that at high altitude this power loss could be too big though.

I'm not a mechanic, but my understanding of altitude is that you lose pressure, which is essential for a Diesel to fire properly. Couldn't you just increase the system pressure a little to compensate for the altitude? Correct me if I'm way off track here.

Of course a bigger turbo charged tractor, say a RX6610PSC, should solve your problems too

If you add air with a turbo you will need to add fuel or you will run lean. 10lbs of boost is a LOT but 2-3 may actually add 10hp or so and give you a snappy feeling.

There are some turbos on the CanAm side by side and there was a 4 wheeler DIESEL made by Arctic Cat that was turbo if I'm not mistaken.

The problem with diesel is that you have to add more fuel and that means you'd have to somehow make the injectors pulse longer or add larger ones so that there would be more fuel there.

With a gas motor it's very easy. Inject with an additional injector into a throttle body that's switched on by a button or at WOT or whatever. With diesel I'm not really sure.

But I know that running lean means running hot and heat melts pistons.

As a Flight Instructor, aircraft must compensate for altitude each flight. As you go up the air becomes less dense. 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. Normally aspirated engines in aircraft routinely use turbos to increase the air density to sea level to maintain full power up the the aircraft service ceiling. It is all based on air density.

If its using a supercharger or turbocharger by definition its no longer a normally aspirated engine.
