Increasing Horsepower

[Tororider]

Have any of you used a dynamometer to increase the horsepower of your tractor? My uncle had it done and we are thinking about getting our JD 4310 upped a few horsepower.

A dynamometer does not increase power ,It is a tool to measure power at pto shaft ? You do the dyno test ,Make adjustments,And Re-dyno ..see the difference ?
Easiest way to increase power is pump adjustment and is fine "In moderation" on most diesels 10-20% + extra is easy and adding a turbo can achieve 20-40% more power without harming anything .
Many stock 100 hp tractors are pumped up and turbo,d to 150-160 hp with no side affects (depending on many things) .The ford 7710's and 7610's are basically the good old 5000 ?

Kubota has the same engine bore and stroke right down the line in their L5040, L5240, L5740 all three are turboed but each has different fuel setting to get the HP they want without a different engine for each.

There have been several members who have added turbochargers to their tractors (and just as many who have started, and then chickened out!). Something i have contemplated myself. I think a little time searching here will get you several threads devoted to this modification.

D7E,
Sorry, I didn't explain myself very well, if at all. I know that a dynamometer is a tool used to measure. I believe you adjust the fuel pump to create the extra power. Like Deerlope said, many manufacturers use the same engine, minus the fuel pump in similar lines. I believe the JD 4310 and 4410 are that way. Just looking for anyone who has done it.

I also know that in larger tractors, "industrial" tractors it is very common because you can gain tens of horsepower, whereas when you do it a compact tractor you only gain a few horsepower. For those of use who have the compact tractors, those few extra horsepower can really help.

A good diesel shop should be able to tweak the pump to give more power. Don't expect the world, but 3-5hp should be possible with few drawbacks.

When you add a turbo you up the combustion temperature. Some engines are designed for that some others I would assume are not. I would look into that aspect of it before spending the money.

There normally is a difference in the engines when turbo'd, the increased cylinder temps normally require oil jets to spray on the bottoms of the pistons to keep them cool.
When they come from the factory many of the turbo'd engines sport about a 20% increase but for after market many only offer up about 15% increase. The turbo is not the only thing done as they also need pump modifications to add the extra fuel.
Turboing often costs about four to five thousand dollars when done so why not just go buy the next larger tractor and get everything built for the extra horsepower.

One of the big differences in the 5000 and 7000 was a turbo.. and many people still drop in M&W kits.. etc.

A new crank might be nice too..

I know a guy that had a 5000 up to 105 hp and stock it was 70..

It lasted quite a while till the crank turned into a pretzle... of course.. he hitched it to big plows and used all of them wild ponies to their max.

within moderation.. i think you should be able to play with the smoke screw a bit without catastrophic issues..
