Turbocharged Tractor

I know a turbocharger adds engine horsepower, but are they worth the extra money? JD 3E series tractors, like the 3032E does not have a turbocharged engine, but the JD 3038E does. Same sized tractor, with about 5 extra horsepower, and 1,000-1,500 more money. Is it worth the extra money for the turbocharger?
 
We have a 4000 series compact. It has a turbo, lots of mid range torque. Worth it to me. But if don't need the HP. Keep in mind hydro eat 8 to 10 HP. Again worth it to me.
 
If your tractor is sized for the correct horsepower to meet your needs and you can get the horsepower in a normally aspirated engine, I"d do that. It"s a simpler set up.

If you are going to working at 5000 ft, you"ll have a significant loss in power from the rating curves which are adjusted to sea level standard day conditions. So in this later case, a turbo will help reduce the power loss that occurs by going to altitude.
 
They are an economical way to add hp, they run a little cheaper on fuel in the real world. However they add a little stress to the engine parts, so its a trade off.

I've got 2 tractors and combines with turbos, good running, fuel efficient machines.

My opinion is a turbo adds to everything bit idle horsepower and torque , so in my experience you will not have the grunt from sitting still that I want in a compact tractor.
 
A bit of trivia; the D19 Allis Chalmers was the first production tractor with a turbo as standard equipment.
 
I think that for every atmosphere (14.7 PSI) of boost, you can get an effective HP boost of square root of 2 or 1.4 times base, if you can get the corresponding fuel in.
 
Too bad the engine and the powertrain couldn't handle the HP... If they would have been a good, reliable tractor at the added HP it would have been something to brag about. But, in reality, not so much!
 
You also have to take into account the vintage of the tractor. A turbo replacement can easily cost over a grand, myself if looking at two equal machines I would skip the turbo just to skip the potential replacement cost for a older machine. Buying new I wouldn't be as worried but on an older machine turbo could be more than half the machine value to replace

Whenever the subject comes up, it seems that there is information about the other differences in the motor if it is turboed. Case in point Ford 8000 vs 9000. There are many different internal parts built a little differently/stronger to insure that the turbo model lasts as long as the natural.
 
That is a good point, a lot of turbo engines have additional oil cooling on the bottom of pistons, and the lower end must be able to handle the HP.
