Upside / Downside of Turbo charging?

[woodlandfarms]

This is a long term lark, but as I am sitting around watching my wife watch a movie I have allready seen I am wondering (from the 429 conversation) what would would be the upside and downside of turboing my Deutz Diesel.

I wonder if it would fit under the hood? If it did, beside bolting on the turbo and such, do I have to change out the injectors? I don't know much about diesel turbo theory so any thoughts or place to get advice would be great.

I'd be leery myself because of heat. Turbo's use exhaust gases to spin the turbine to compress the intake air. End result is more heat generated from higher compression in the cylinders (more violent explosions) and the hot exhaust gas being held inside the engine compartment longer as is routed through the turbo...

Combine that with an air/oil cooled high-compression diesel engine, and you could be looking for trouble.

Note that Porshe made (and still may) turbocharged air-cooled engines, and I've seen quite a few turbos added to air-cooled VWs. But Porsche spent tons on R&D, and the VWs tended to overheat, burn exhaust valves and self-destruct, often in dramatic fashion...

It looks like it would be a 14 to 16 HP increase. I guess in Diesel words it is a lot, (to go from 65 to 79HP)

I don't know about the heat situation, I am trying to find where they put the turbo in the first place on this engine.

But, as I bend the heck out of the front with 65HP, I am sure I would destroy the front with 79...

But, I still want to explore this with your guys advice if you are up for the chat.

I did a movie that Porsche funded a few years ago. For filming, they gave me a 911 GT2 to drive back and forth to set. For whatever reason I never got a ticket, but when you hit 3200 RPM and those twin turbos kicked in.... MAN, what a rush...

I'm not sure you'd gain much as the power output of your tractor would still be limited by the hydraulic system.
Do you stall your engine often?

 

[woodlandfarms]

Nope. Seldom stall, although I have yet to really work on my steepest hills.. I do bog down a bit...

Sizing of the turbo is very important so you may want to see of you can find a chart that will help in that regard. Keep in mind that a turbo won't add any power without adding more fuel. I would check with your local injection pump shop to see if your pump can be re-rated for more fuel. BTW many fuel injection shops also offer turbos. They may have worked on a similar project before.

My series of engine comes normally aspirated or turbo charged. From all indications it looks like there is no mechanical change, although I can't find out any pump / injector info.

but digging into it further I saw some photos of how it is rigged on other devices and I doubt it would "fit under the hood".

Still, not going to take it completely off the burner...

My 35 HP Branson CUT becomes a 40 HP Branson CUT merely by bolting a factory turbo on. AFAIK, there are no other differences.

The Deutz is a standard bolt on; you replace the exhaust header with a new one that has the turbo integral to it. And, yes Virginia, you do have to adjust the injectors, but it isn't that bad, you just have to be surgically clean.

I think it is a pretty nice design. If you look around on the web, you can find pictures; I looked into it when I was first buying my 1445, just in case. The cylinders, cooling etc. have been designed for it.

That said, given all of our collective experience, I think that you would be well off increasing the size of the fan on the hydraulic cooler, and perhaps adding a cool air pusher fan just to keep the engine cooler, and, perhaps more importantly, keeping your hydraulic oil cooler.

But if you aren't running out of power, why bother? Are you going to put one of those skid steer tree eaters on the front and just suck up your blackberries?

All the best,
