Small Diesel Engines - Natural Aspiration vs Turbo Charged?

[Industrial Toys]

I own a little Steiner with naturally aspirated 3 cyl Kubota. Ventrac "apparently" had all kinds of heat related issues with their similar turbo powered units. Unless I understood it totally wrong, Bobcat had the same problems with early Toolcat Turbo units.

If you don't have turbo you must have volume, but still you get a very large lazy diesel, on the old Mercedes Benz 2636 we had a V10 around 19l engine volume non turbo, used very much fuel and did not move those 26t particular fast....

Turbo are free horse power

I only had one turbo....a 1979 Cabover IH OTR tractor with a 400 hp Cummins Big Cam 6, turbo charged. On farm tractors don't, never have, never will. Only if I lived at high altitude would I even consider one.

Why not?

I used to haul heavy equipment and the dealers like Cat, Volvo, John Deere had me cover the exhaust with a bag or duck tape to prevent the turbo from spinning and causing it to burn out the bearings. But it depends on the direction of the machine if it loaded with the exhaust opening to the front where the air is forced in the exhaust it needs to be covered . But if it is facing rearward you don't need to cover it because the air is not being forced in the exhaust.

Why not?

I"m curious as well. We have 10s of thousands of hours on our equipment and rarely have any turbo problems...If we do, they aren't horribly expensive and pretty easy to change out.

As a Diesel Development engineer for about 35 years, all I can say is that there is a lot of bad or ill informed information in this thread.

Rather than getting into a pissing match, I’ll leave it at that.

How about offering some generic comments on your personal experience over the years with diesels and turbos? That way it's your personal opinion and no one is challenged. Your experience sounds like it would be very helpful.

The tractors listed in his profile are naturally aspirated.....Hmmm......
