engine: tuning more HP?

[Jerry/MT]

The Massey 1652, 1655, 1660 all use a 3.0L 4cyl Iseki diesel, but produce 52, 55 & 60 HP. Haven't received a real answer from the Massey dealers I've contacted, and no responses in the MF forum, so..........

Anyone know if (and how) the 1652 could be tuned to make 55 or 60 HP?

Thanks in advance.

For a diesel you can increase the fuel delivery and increase the max power output. This often referred to as "turning up the pump". This results in higher peak pressures and temperatures and there must be sufficient design margin in the affected components to be able to tolerate the increased loads and temperatures that result. Otherwise durability of the engine is compromised. Tractor engines are generally de-rated in order to have long operational lives. Increasing the HP without resigning the components cuts into the durability margins that are targeted in the de-rate.

Another way is to use a turbo to increase airflow through the engine. Again the loads and temperatures go up so the components must have sufficient design margin to be able to tolerate the increases.

Increases in compression ratio can also increase the power output.

Other ways are changing cam characteristics (increased lift and duration) IF the cam has not otherwise been optimized for this all ready in the basic engine.

These methods apply to a fixed displacement engine. You can also ways increase displacement (by boring it out) and increase HP but your question was specific to an existing engine.

I don't think you would have any trouble boosting a 1652 up to a 1660 but then if you are buying used, likely there isn't much difference in price between a used 1652 and a 1660 so perhaps the way to go would be to just look for a 1660 at a good price. There may not be much difference at all once you pay a shop to turn up the I.P and dyno the engine which would be the only safe way to do it. Too much risk in just cranking the screw up without knowing how much you increased the HP.

Can't... In the 16xx series, they didn't offer the 1655 (shuttle) or 1660 (PowerShuttle) in HST. I need HST for what I do, no way around it. If I could have PowerShuttle, I'd skip CUT'S all together and move up to the next series.

So, I'm stuck with my 1648 (2.2L) or the 1652 (3.0L) to keep HST.

If I jumped to tier 4 (17xx series) they now offer the 1758 in HST (59 HP)... But that's way too much more money to justify the jump.

So... The only way I'd jump to 1652 right now is if I found one at around "break even" pricing, and IF it could be tuned up for more HP like it is in the 1655/1660.

Btw, had a Massey dealer recently say that they couldn't turn it up there, because it's "set from the factory that way" and it would require tuning the pump and an ECU flash.

Thoughts on that anyone?

Back in the early 80's I was tractor shopping and went to the massey dealer. He was waiting on another customer and gave me a some papers on the tractors I was looking at. The 255 and 265 were the same tractor just different HP. I asked him what the difference was and he said the pump and injectors. There was over $2000 difference in price and he said he would turn a 255 up for $200 so I got the 255 and after the year wait was up He turned it up for me. Put 265 injectors on it and turned up the pump from 52 HP to 74HP. I never had a single time that I wished I had not turned it up. Pulled better and did more work per gallon of fuel. Ran it for 10 years and sold it when I sold the farm. Find a tractor mechanic that has a hydro hp tester. hooks to the pto and uses water to test hp and get him to do it for you. I would not do it without the mechanic having a tester.

What is computer controlled on that tractor. With some common sense tractors can be easily turned up for more power, my neighbor has turned up all of his tractors and hasn't had any issues for years and thousands of hours but he uses common sense operating them (tractors are all diesel, IH 986 and 1086, ford 3000 and 5000, case 1070?, McCormick CX95, JD 4440).

Pull a Fred and put a turbo on it! That's my plan to up the ooomph of my lil 3005.

I'm not sure ... I was thinking they were speaking out of their rear when they told me it would need an ECU flash

No interest in a brand war here but... If you really need HST and want more HP - there are a few other colors that meet those criteria.

Very true. But for a bunch of reasons not meant for this thread, I'd prefer to stay with the Massey.

I'm not familiar with the Massey but I would agree. I didn't think any of the manufacturers went to electronic controlled engines till tier 4. If it is a mechanical injection pump then a flash wouldn't be needed since the ecu has no control over fueling.
