Power mods for 3647 engine

[twayneray]

I would like to see some ideas and proven mods. that would increase the power of my little diesel in my 2005 3647. This has been a good little tractor, but as the warranty has long since expired, i am interested in bumping the power up on this little unit. I think it would be a lot of fun to have this size tractor putting out power in the 60-70 hp range. Is this feasible? Is it even achievable? I may have to be content with just running a straight exhaust and turning up the fuel pump just a bit. This little engine is supposed to be bullet proof so lets see what we can make it do!! Let the ideas roll boys!

Don't have any personal experience with that engine but assuming it isn't already turbo charged, that is the first thing I would consider other than maybe turning up the pump. A turbo would very likely be the most reliable means of making a substantial increase in power. There are a number of turbos out there that may be appropriately sized. I have read about guys using motorcycle and automotive turbos on their tractors, so you aren't necessarily limited to using a unit from an agricultural application.

While all manufacturers typically "overengineer" when it comes to how much "power" their components can take, I'd be careful. I'd hate to see you ruin a perfectly good tractor in your quest for more power...

All that "extra" HP could raise havoc with transmissions, transaxles, etc...

I agree. The 5530 Branson is 55HP and it uses the same A2300 but with a little turbo. Of course the typical warnings....blah, blah....but let us know how it works!
