Turboing the Yanmar

[dieselfume1]

Hello Gator owners,

I'm here hoping that you all can give me some insight and advice into turboing my 2012 polaris ranger..... now before everyone goes on defence, just let me say I've been owning john deeres all my life and all of our farm equipment is deere, except our UTVS....not because polaris is better, but for other reasons entirely, which I will explain if it interests anyone.... The real reason I'm here is because I know that many of you are diesel owners who have the little cousin to the yanmar that's in my Diesel Ranger. I think the deere's engine is an 855cc yanmar, and the one in the polaris is the minimax 904cc yanmar. very close in size and most likely very close in HP. My ranger is in need of a HP boost. The diesel gets around ok, but with a cab on it, it's really shut down my top speed and hurt my acceleration, which wasn't very good to begin with.

I'm serching for a good turbo to put on this engine. PPE sells a turbo kit for $2600 for my ranger, but is way overpriced for me. I'm thinking I'd like to do this swap for $1000 or less. I'm an EX caterpillar mechanic, so hooking it up won't be the issue, but I'm gonna need a correct sized turbo, and some insight.... I figure there's gotta be alot of you 855D guys that feel the same way I do about the little yanmars in these things... great engines, but need a little bump.

Anything you guys could help me out with on this as far as good turbo's to use, where to get them, and maybe some of you would even have somthing for sale? It would really be appreciated!

Adam,

Welcome to the forum! No one will go on the defense here, its a great group of people. I can't answer your question but if you give it a little time there are a lot of very nice and knowledgeable people on here that I am sure will be more than willing to share their knowledge and experiences with you!

Dan



p.s. just curious, what part of the country are you from ?

[dieselfume1]

Thank you for the warm welcome!

I'm from southeast Montana, and ranch for a way of life. My UTV is critical to the operation here, and with out them, we'd really be at a great disadvantage! I'm planning on owning this Ranger for about 5 years or approx 4000 hours. The last two rangers I owned (gas700s), had about 2000hours each on the clock when I sold them. the diesel should be able to put them both to shame, and should still be running good when the frame and body fall apart around it!

Hi Dieselfume and Welcome.

The XUV series from 2007 to now use the 25HP, 854cc, 3 cylinder, OHV, 4-cycle diesel Yanmar engine.

The ProGator uses a Yanmar Configuration 3 cylinder liquid-cooled diesel High idle speed, rpm 3,450 rpm Displacement, cc 1115 cc but is dumb ed down with Transmission Manufacturer Kanzaki
Configuration 5-speed synchro-mesh Maximum speed 19.1 mph 4WD option Automatic, on demand system.

We seemed to be electronicly controlled by a governer that kicks in at 30mph. I have chipped away at my Dealership and the head mechanic said you could change spool sizes but then again you be at maximum engineering specs that the transmission would tolerate.

So if we put a turbo on the diesel it would be only for the gitty up to 30ish mph and then tard out at 3/4's rpm. We would love someone who has the time and cash to disassemble the spools and transmission and elctro governor and figure it out. :strpot:

How is your Ranger governed? :lurk:

[dieselfume1]

No govonor.

The limiting factor on the ranger is RPM.

The 904cc yanmar maxes out it's rpm at 3600, so when the engine governs out at 3600 I'm doing roughly 41 mph. I can attain those speeds on slight downsloaps, or going with the wind. before I had the cab on it, it would do 40 mph on the flats all the time... the cab weight didn't hurt the diesel as much as the wind resistance did. I talked with a guy yesterday that bought the PPE turbo kit for his ranger which increases the power by 7-9 hp minimum, and he says it'll run hard against the govonor all the time now... with a cab, uphill, pulling, into the wind, it doesn't matter, the thing just hauls butt.

I already modded the pump for more fuel, but will need to add more when I get some boost to it. Just need to figure out what to boost it with and where to get it.

over the long hall turbo will efect the rings sealing eventually causing it to use oil turbo models usually have more rings on each piston

This turbo is on ebay, I bought one to try on a 620 I but it's so cute I may never use it,all jokes aside it should wake your yanmar up you will need to turn the fuel up somehow ,nozzles or pump.
