JD 5083e Tuning

Here's links to the Nebraska tests.

Boost on 5083E measured at 10.7 psi

Boost on 5101E measured at 14.1 psi

FWIW, we have the same engine naturally aspirated in our 5420. It is rated at 82hp at the engine and 65 PTO Hp. Not sure why the turbo 5083E is only about 5hp more at the pto.

I can't answer any of your questions as to how, but I can offer a little help. I have a 5101 in my shop outside. If you have any specific questions about parts or sizes, etc. that I can run out and check for you, let me know. I'd be glad to do so.

(Gigem, by the way. I lived in College Station for several years as a kid. I'm an Auburn alum, but I'm still an aggie fan as well)

No doubt the 101 would have more boost as a result of more fuel, not necessarily larger turbo. For example, my cummins 6.7L with create 10psi+ more boost with a chip tah without and the same turbo. I think (think), it is simply more fuel.

Do you know which Stanadyne injection pump model is used in the 5083E versus the 5101E? If they're the same, the solution might point towards electronic power module tuning for increased fuel psi and turbo boost control.

Per my question above concerning the Stanadyne injection pump model used, I've found the following performance chip product offering for the 5083E: 5083 E John Deere Tractor 5083 E Power Chip Diesel Performance Chips however, it notes "This Product will not work with Stanadyne Type Fuel Systems. This Product Works with Denso Common Rail."

I found that before. Theres no shortage of performance products for the common rail. A member of this site refered me to a company out of California that has a module for the stanadyne pump. I'm waiting on them to get back with me on what it does and cost.

Yes, that was also me that made the referal on the California company to whom I have also requested info. My question was: Are we certain the 5083E uses a Stanadyne pump or is it using the Denso common rail?

I own the tractor and it is the stanadyne.

Good thing I like aggies too, cuz I work in College Station everyday.

AGGIE, you need to find out why there is more boost. With more fuel, you'll need more air. It is maybe an electronic controlled waste gate?

You need to go to deereparts.com and do some research. There shows to be 2 different 5083E's and also 2 5101E's. Each shows 2 different engines on the dropdown lists. Maybe you already know which one you have. There seems to be a common turbocharger number for one engine type. Maybe you just need to get your hands on a Electronic Control Module for the 5101E. They list the same ECU P/N for both tractors but has a side note to accompany the order with the tractor's serial number???

There is also a performance monitor listed under the electronics dropdown list. Guessing that it looks like it could be a mechanic's tool for programming the ECU maybe???

You need to maybe ask the mechanic why the 5101 has more boost.
Keep us updated on anything you find out.

Turbo boost is a function of impeller rpm's, vane pitch, and diameter - not fuel. Some turbo's have a fixed vane pitch and other's have a variable pitch (and some have 2 impeller's - Ford, etc).

Variable pitch impeller turbo's are electronically (computer) controlled and therefore can be adjusted with a "chip".

I don't know what turbo the JD 5083E has or if the turbo is the same on all the series. If they are the same turbo - then adjusting the pump and injector's (may have to swap out these for the 93 or 101's) should get you where you want to go..
