Turbo on YM2000

[sacguy]

I suppose I should clarify on the throttle response a bit. When I pull my disk, I run fast. At the end of the field, I throttle down and turn. When straight again, I throttle back up to speed again. Throttling down just helps me turn.

I have swapped the rears, but it is still too narrow for my liking. There is a YM2200 at a Ford dealer on consignment here, but it is very rough-besides being one that is hard to get parts for. Right now, the owner wants too much for it, but if I can get it cheap enough, I'll get it. On that one, the front is adjustable. The other alternative is just to fab a new axle or retrofit a different brand axle for the front.

I know I need another tractor and am looking. I just haven't found one which I can afford yet

Oh, I forgot the best thing. Turbo cost me $300 new. Everything else I fabbed up myself, so total cost was fairly cheap. I don't know how good this chinese turbo will hold up, but figure I'll find out. Couldn't really go wrong for the price, plus my boost is not too high, so I figure it is ok for the motor.

I like the idea. I know budget wise I cannot afford another tractor right now and we mow fields as a side job to help support my boys (3) hobbies (scouting and 4-H) a little extra HP would help out when people let the grass get chest high and you are having to mow in low range.

As long as exhaust temps stay low enough the engine should be fine with conservitive boost pressure.

Lets face it they do not beef up or redesign the turbo engines used on other tractors (the only changes may be piston design) the whole idea is to get more power from a smaller package for less money and the way they do that is to use existing designs that the engineering and tooling are paid for and drop in the turbo with minimum design changes and tooling cost for the increased HP

Congrats on the very cool project. Post more pictures when you get a chance.

 

[sacguy]

I'll try to take some more tonight. Thanks for the compliments.

Very nice setup!

You should be capable of operating up to a max of 0.5bar or about 8 psi max boost, which effectively increases the displacement of your engine by an equal amount (ie 50% larger displacement), but above 0.5bar you'd need an intercooler and significantly more fuel per injection event. SInce you have a BOV, you can regulate it to be below 0.5bar even under severe load.

Sacguy, don’t justify to anyone what you did, enjoy what your creation for what it is…. COOL! We put a turbo on a junk YM2210D a few years ago and entered it into a 2 cylinder only tractor-pulling contest. It smoked so bad out of the container we knew we could never sell it and the rear fenders and hood were completely rusted off. After putting the turbo on we tried everything we knew of to blow it up including turning the exhaust cherry red for an hour. To say we failed is an understatement, that tractor is still running today and has 500 hours on it since it left. I think it even smokes less. That is a good motor for endurance testing so enjoy your sweeeet tractor.

Drop the stock air filter (you can keep it for later if you ever nerd it back up) and put on a larger canister or build a box above the battery that contains a K&N. Put a snorkel on the box to limit dust intake. The stock filter is too small for the increased airflow. On a dusty day you will have to clean it every hour and if your turbo dies it will be the air filters fault.

I do fully intend to replace my air cleaner. I just cobbled up my old one to see how it would do. I want to look in the junkyard and see if I could get one off an import car and try coming up with a pre-cleaner before the air hits the air filter. Glad to hear the 2210 is still going strong. How much do you estimate you increased the power? I figure these little motors could take a fair amount of boost, but since this is a tractor I depend on for working, I am keeping the boost at a modest rate.

This is the one on my little 1110d. I havn't done much testing with it yet as I don't have the pyro hooked up.

The turbo is off a Yamaha Seca 600. It's small enought to fit in the palm of your hand. The exhaust pipe is 1-1/4" schedule 40 pipe that I welded up.

 

[Cord]

The biggest problem that I fear is that the turbo may be too large. The bike was a 600 and my diesel is a 630 +/-, but the difference is in the rpm range. The bike reved up to 10k, my diesel tops out at 2.6k. I would have used a smaller one, but I havn't found it.

 

[DavesTractor]

Well done!

 

[Chuk]

Cord, you stole my idea..... but I'll probably never get around to it anyways. I think your 1100 is similar in size to my 135. Honda turbocharged some gn500's mabye they used a smaller turbo. Did you hook up a boost (manifold pressure) guage?

 

[Cord]

My 1110 is pretty close to the 135. I just got the pyro gauge the other day, and havn't purchased a boost gauge yet. I also want to hook up a oil pressure gauge. On a larger tractor I wouldn't be concerned about the oiling system, but I only have a two quart capacity! The oiling hole on the turbo is only 3/32" so it won't steal too much oil.

Cord, that is flippen sweet!!

[mark777]

I agree 100%. It is SWEET. This is something I haven't done and would like to try it out.

Thanks guys! /forums/images/graemlins/laugh.gif

 

[sacguy]

That looks great. Your welding is a lot better than mine. I'm not sure where you could get a smaller turbo. Perhaps you can get by with changing the vanes?

 

[SkyPup]

The smallest automotive wastegated turbochargers utilized here in North America are the turbos off the Volkswagen and Audi 2.0 liter gasoline engines, the Garrett GT15 and the KKK03 (their two liter turbodiesel turbocharger models (VNT15) all have variable vane and nozzle technology which requires electronic CPU modulation to control the boost pressure.)

Both of these tiny turbo models put out about 1bar boost and the turbo maps have good choke and surge characteristics. You can get them at foreign junk yards or on ebay for about $300-350 used.

 

[sacguy]

I did see one on a Subaru and if I remember correctly, that motor was a 1.2L and I don't quite remember the turbo brand that was on it. I had thoughts of grabbing it, but my big hands don't quite fit in those little engine compartments very well.
