I have a x1120d model side by side . Just wondering if anyone has turned up the fuel and made any more power with theirs. I love my tractor but I just wish it had more power in muddy pastures . Thanks for the help !

Put a turbo on there, should make plenty of power then and it would sound cool.

I have done a turbo on those. 1100 and 1120 both.

It don't do anything. You can't hardly hear it. It might accelerate a tiny bit faster, but at my altitude (like 300') it's a waste of a lot of money & time. Made 7 psi and yes the fuel was turned up per directions. It still tops out at 23 mph. In order for turbo to actually do anything the fuel timing has to be changed and when you do that it's not ideal at no boost (idle/low speed) conditions. Mechanical injection just does not deal well with turbocharging. Electronic is a completely different story which is one of many reasons the 7.3 IDI N/A was a turd and the 7.3 DI turbo (T444E) wasn't as much of a turd. Really the entire engine has to be revamped in order for the turbo to actually do anything. If you look at a D1105, there is VERY little space between the piston crown and the cylinder head. Where's air going to be forced into for combustion? Many dedicated turbo diesels will have a gigantic cup built into the pistons-for many reasons, but one of them is to give a place for air to live. The 1105 just ain't made for it and honestly at 10 psi (no intercooler), it might make 2 or 3 more HP on a cold day, a hot day maybe half that. Needs intercooler needs injection changes, timing changes, and a ton of other things to really do anything; and even then you've got to be careful with EGT. A diesel engine will melt itself if you ain't careful and with little warning.

I did a turbo on my old G1900 (D722) and even after adding a little VW intercooler to it, I could tell VERY little difference; even after adjusting on the fuel a little. It looked cool when the hood came up but that's about it. 13 psi is all it would do and that was full throttle under a heavy load cutting grass.

well with reading that, I just installed a new synthetic winch line.....I was hoping to get more power instead. hmph!

If you want more speed, get a new Sidekick. My wife got one and it tops out at 49 per and gets there quick. Guy down the road has a Kubota diesel side by side. When I pass him, I suck the paint off his hood....:eek:

My T444E isn't a turd at all. In fact it makes 360 at the rear wheels with a full Gale Banks kit and the ATA. It's a simple, easy to work on engine, unlike the new ones but then I'm not pro electronic anything, tractors included. Aren't the diesel Ute's gear bound anyway?

Farmtractor,

Suggest you search some of the other sites geared toward turbocharging and even this one for others who have added turbos. It seems they have a different experience.

Keep in mind top speed on flat land won't change, but in situations such as hill climbing or deep mud any increase in HP should make a difference.

Let us know what you do.

I have always set the timing the same on boosted diesels as N/A and used the more durable "small valve non-turbo heads" on my Chevy diesel.
The only engines that should be set up differently are gasoline motors.

if at altitude a turbo will help some. At my altitude, it's $2300 for the entire kit + labor to install, for a couple horsepower which honestly when an RTV1100 weighs close to 2500 lbs, 2 hp is really not that noticeable. Then it's non intercooled so it's blowing hot air, which is VERY noticeable after running full throttle for a little while, just don't make anything spectacular as far as torque increase. People are gonna argue with it all day long but look at the 94.5 through 97 powerstroke 7.3 No intercooler. Then in 99 they put an intercooler in the truck and the power loss on a hot day towing up a long hill mostly disappeared.

Somebody mentioned their T444E makes 360hp. Fine. Compare that to a newer 6.7, heck even a 6.0. They're more powerful make more torque better fuel economy (but a little) quieter smoother lighter faster more responsive. Why? Technology. Piston shape. Electronic control of fueling and air. 4 valve heads. Etc etc. 360hp at the wheels is still a turd in a pickup that weighs 8000 lbs. I have one so I'm well versed (2003 F250 CCSB 4x4 Lariat-tuned). Similar to an RTV diesel. 2500 lbs, 24 hp. It's a turd, spend a bunch of money on a turbo, still a turd. The head don't flow, the transmission eats a TON of power and it's designed specifically to deal with 24hp and about 60 lb-ft of torque to plant it smoothly to the wheels, the injection is designed specifically for natural aspiration the reasons go on and on and on and on. Real similar to a diesel pickup. You can do a little to it for a lot of money for a small gain but in the end you'll still end up getting your butt handed to you by a newer faster more powerful quieter smoother machine.

The little D1105 engine is designed specifically to make X amount of torque at X engine speed all day long at full throttle and at full load with a specific amount of fuel usage. It's not a good engine for an RTV that idles it's whole life and is asked to make sudden speed changed through a hydrotstatic transmission that is unique in it's own design. HST's usually either make good torque or good speed but they don't generally do both very well, so Kubota played with it some and made it kinda do both, though not very well. An inefficient belt drive system is WAY more responsive and of course faster; but kubota didn't want no belt drive because they wanted it to be "automatic" and "tough as a tractor"-and it is, for the most part. Just slow, like a tractor.

I did and I have a 97, 7.3. IDI (T444E). t's perfectly fine for my uses and it sounds like a diesel should. and other than the High pressure Unit injection it's as reliable as a rock...

and of course the 97 was the last year of the OBS so it's a very desireable truck and mine is mint. Never seen snow, never seen salt. No rust, 4 door 4 wheel drive long bed.

Solid axles too. No IFS crap.

My little RTV-X900 has almost the same performance.... it’ll do 20-24 mph at full speed.... and anything faster would be downright scary with the oversteer-condition all these RTVs have. You could hurt somebody trying to go any faster.

My son has a Kawasaki Mule that will do almost 50.... and he set it’s governor DOWN to 25 to keep the teenagers from killing themselves.

He wishes it had the pulling-power of my RTV.
