Ford Tw-15

Mccloy_Farms · Sep 26, 2023

I got a tw-15 thats been sitting for 20+ years. Got it started, been using it alot recently and done alot of work too it. Most of the eletrical is okay, ac doesnt blow cold, heat knob is seized, no lights work, frontmost cylinder manifold leaks. So, I have a few questions on the tractor that have popped into my head. Do they make a heavier duty clutch for this? Can I put a bigger turbo on, and if so, which one? How does the tw-15 compare to the 25, 35, and the 8830?

I had a 9000 that I used strictly for pulling competitions. I bumped the HP by increasing fuel to max and advancing timing. I beefed up the clutch by converting to a double disc. Conventional wisdom was that going to a larger turbo would likely result in blowing the head gasket and needing larger head bolts.

You can go on TractorData and see how it compares to the other tractors. The TW15 is the second-smallest tractor in the series, "child" of the TW10 and "parent" of the 8530. The 8830 is the largest tractor in its series, equivalent if not slightly more HP than the TW35.

HP and a longer hood are the main differences as you get bigger in the TW series. More hood for more fuel tank I guess. The 30 series added powershift as an option.

Does the tractor do the work you need it to do? Then don't mess with it. I do not understand why everyone's first instinct is to add a turbo if there isn't one, install a bigger turbo if there is one.

Not a ford person in tractors and don't know much about them. I also don't understand the turbo or bigger turbo idea either if you need or want more HP then buy a bigger tractor for the power. Making power in little engines makes for a lot of money spent for nothing but a pile of parts to send to the junkyard. There's no replacement for displacement in the HP category.

A friend of mine has one making around 200hp - I'm not sure what all he did to it, but he's a Ford expert. I believe they use the same 401 cubic inch block all the
way up to the TW-20, so I would guess it will take it

The shop that rebuilt the pump on my 9000 said that it should be making around 500 HP. That may sound like a lot but you need to be getting 250 out of a Farmall M these days to be competitive on the pulling track.

I don't really have enough financial resources to go out and buy a bigger tractor. Just looking to see if their was an easy way to gain 30-40 hp. It has the stock turbo and fuel turned up by the dealer
