How much power could i reliably get out of one if I fitted an intercooler ?

The Marine version does comfortably over 350hp, but obviously you have the huge luxury of an almost infinite heat dump for intake charge cooling.
To answer the OP's Q- with some bigger injectors, DV's in the pump, and reasonable air to air cooler, 300hp would be fairly easy.
Unlikely to be able to sustain that continuous as the tractor radiator would be too small at that power level though.
I am of course ignoring any transmission & diff limitations !

Alastair Cooke in Northern Ireland has one doing in round 400hp I think. Have a look at his YouTube channel and an interview with farmflix on YouTube for more on what changes he has made. Think he stated the poweshuft transmission in his 8970 is rated for 600hp.

Allegedly not so good after Deere bought them only to find Ford held the patent and could not use them, but they did later appear in some Masseys
Come to think of it, there is a known issue with the 'smaller' Powerstar 7.5's.
From memory the version fitted to the 8670's didn't have under piston oil squirters, and when the fuelling was tweaked a little too far the piston crowns would overheat and fail.
It wasn't an issue on the 3 bigger models, but it caught out a lot of 8670 owners who were after a cheap upgrade but ended up with the cost of a rebuild.

Do any TMs have under piston cooling?

The ones I’ve seen all do, we’ve a few grey ones in bits aswell which have them

Constant load too, and no chance of a sudden stress torque spike that you might get with say a tyre spinning suddenly gripping.

No it'd be pretty poor at handling load transients

If i put a set of butterflies with conditioners on , it should drive them if i can keep the rad clean.

Plenty of TM 190 used to run them, they were cooking the backends for fun though but the engine was ok apart from the silly injector pump!!!
what have you got?

A TM165 with mechanical pump. Was harm being done to the back ends or were they just running very hot? The oil cooler is a bit petit on the 165. I was often thinking of fitting another or 1 bigger cooler but never did yet. At 40K on road work they get fairly hot.
